Evolution Observed in Darwin’s Finches

neurologicablog Feed - Fri, 11/24/2017 - 4:55am

Just two weeks ago I wrote about “Evolution Caught in the Act” – I was writing about fossils that are clearly transitional and occur within a major evolutionary change, like a land animal adapting to aquatic life. Now we have another report that justifies the same title, although this one is in living species.

For this observation we go back to the beginning, to the Galapagos where Darwin made observations critical to his development of evolutionary theory. The Galapagos are a chain is relatively young volcanic islands, far enough from the mainland to provide relative isolation, but close enough for life to find its way there. Most famously, some ancestral finch species found its way to the island. Their descendants then adapted to a variety of food sources, most obvious in the change in beak size and shape, optimized for its new use.

What Darwin observed is that the Galapagos finches filled many of the same niches as other bird families in other parts of the world. He had to puzzle out why on the Galapagos all those niches were filled by finches. He figured out that they must be descended from an ancestral finch, which also means that they have speciated into a large number of different finch species as they adapted to different islands and different food sources.

Modern evolutionary scientists have also capitalized on the unique natural experiment represented by the Galapagos. They have been closely observing the finches for decades, and this has provided a massive set of direct data. All this work has paid off in the observation of a chance speciation event.

Scientists report that in 1981 they observed the arrival of a male cactus finch (Geospiza conirostris), a non-native species, to the island of Daphne Major. The relatively large male mated with native female members of Geospiza fortis, a medium ground finch. They produced fertile young. In the 36 years since the descendants have produced a stable and isolated population (now about 30 individuals) – researchers all calling this the big bird population.

Importantly, this big bird population has remained completely genetically isolated from native populations (called “endogamous” – mating only within a group). The big bird population are larger than the native ground finches, and this has enabled them to exploit a new food source. Further, the native females do not seem to recognize the song of the big bird males, and so do not mate with them.

The one critical ingredient for speciation is genetic isolation. However, this direct observation documents the fact that isolation does not have to be geographical. Genetic isolation can occur in species that exist in the same physical location – which is called “sympatry”. This would therefore be an example of sympatric speciation.

Once populations are genetically isolated there are a number of processes that can make them diverge over time. Simple genetic drift may be enough – random and non-directed changes in gene frequency with occasional new mutations thrown in.

However, if the populations are under different selective pressures they will also demonstrate directed changes over time. That is the case here, as the larger big bird finches are exploiting a new niche.

In this case the researchers were expecting that the immigrant bird and his offspring would simply be absorbed into the native population. This can introduce new genes into the population, but would not establish a new species. They were surprised to find that the population remained genetically isolated. The mating habits of the finches, however, made this possible.

This, of course, is just one case, but it adds to other examples of population changes in living species. This is now one of the best cases of a speciation event observed in real time in a living species. I also shows how quirky evolution can be. Random events, like the chance migration of a single male finch 65 miles to a nearby island, can trigger evolutionary change. Further, there are many things that can genetically isolate populations, and simple behavior is one of them. Even very similar and fertile species can be genetically isolated by behavior, such as mating song.

It is cool that almost two centuries later the finches of the Galapagos are still teaching scientists about evolution.

How Wikipedia Tackles Fringe Nonsense

neurologicablog Feed - Tue, 11/21/2017 - 5:03am

Wikipedia is an interesting experiment in amateur crowdsourcing of information. I think it is a massively successful experiment, but it faces specific challenges. This page on Wikipedia discusses their approach to what information they allow to remain in their pages. They have a number of policies and practices that are meant to act as a quality control filter.

In my opinion they have settled upon a reasonable approach that might even be used as a model in other contexts. They begin with a completely open model – anyone can become a contributor and add information to Wikipedia. This is the crowdsourcing angle – many hands make light work. There are currently approximately 5,505,947 articles on the English language version of wikipedia. Wikipedia was founded on January 15, 2001, so that is almost 17 years. It is hard to imaging creating a reference with that much information by any other method in that much time.

So the wiki model is ideal for quantity, but what about quality. From the beginning there were concerns about the quality of the information – if anyone can post information, how can we know how accurate it is? A 2008 study comparing Wikipedia to other references for historical articles found Wikipedia to have an 80% accuracy rating, compared to 95-96% for other references. However, a 2005 Nature study of science entries found that Wikipedia was almost as good as Brittanica online – with no differences in major errors, and with an average of 4 errors total per article for Wikipedia, and 3 per article for Brittanica.

There haven’t been many studies since then, but a 2012 small follow up study found no significant difference between Wikipedia and other sources. Wikipedia has tightened its editorial policies over that time, so the improvement makes sense.

What are Wikipedia’s quality control policies? They require information to have independent verifiable references. Further, they maintain a stance of neutrality toward controversies. They see this as appropriate for a standard reference. It is not their job to debate information or to give a soapbox to every fringe view, but to be a general reference for consensus scholarship.

These filters are absolutely essential for any open source project like this. One primary reason, as they have learned first hand, is that enthusiasm is not always proportional to quality. In other words, advocates of fringe ideas are likely to have a great deal of energy in promoting their views. They feel that they are in a beleaguered minority and have to promote their view against the tide of mainstream opinion. Wikipedia, without filters, is set up to give disproportionate attention to a vocal minority. The filters are necessary to make sure the information in Wikipedia reflects the balance of information and opinion, not just the enthusiasm of its advocates.

Wikipedia admits, however, that its filters are not currently adequate:

This maneuvering and filibustering is soon likely to exhaust the patience of any reasonable person who naturally prefers not to reason with the unreasonable, and who, unlike the advocate, has no special interest or passion other than striving to maintain neutrality. Additionally, by continually engaging fringe advocates in endless argument, you run the risk of turning Wikipedia into a battleground or a debating society. At the present time, Wikipedia does not have an effective means to address superficially polite but tendentious, long-term, fringe advocacy. Some contend that this is a main flaw of Wikipedia; that unlike conventional encyclopedias, fanatics (no matter how amateur or idiotic) can always get their way if they stay around long enough and make enough edits and reversions. [3] In this sense, Wikipedia’s ‘commitment to amateurism’ does not always work for the best interests of the project.

What I find particularly interesting is that the Wikipedia experience is a microcosm of a free society in general, and not just with social media. In a free and democratic society everyone has a voice, and everyone is equal. However, information is not equal. There can be dramatic differences in quality of scholarship, and those differences matter.

Shouldn’t the free marketplace of ideas sort it all out, though? In my opinion, yes and no. A marketplace is not a neutral void, it is a system with its own rules and forces at work. The feedback mechanisms will tend to lead toward certain outcomes, but those outcomes are not necessarily optimized for the general good of society.

For example, within a marketplace subjective value is placed on certain things, qualities, or services. The relative value of the various components of the marketplace will have a large effect on outcomes, which may have very negative long term unintended consequences.

That is essentially what the Wikipedia editors are saying – the open system by itself favors enthusiasm over quality, and that may not optimally achieve the goals of creating the best general information reference. The Wikipedia editors have therefore come to the same conclusion with their experiment that society has come to with the centuries long experiment with capitalism – the free market is powerful and should be leveraged, but we need to monitor the effects of market forces and tweak the rules to mitigate unintended consequences.

To take the broadest view – systems can have either top-down or bottom-up processes. Both have their strengths and weaknesses. A pure top down system is slow, cumbersome, and oppressive. It is well-controlled, but will get there slowly. A pure bottom-up process is chaotic and easy to exploit. It is fast, but you can’t really control where it’s going.

As with so many things in this world, the best option seems to be a balance between the two, and that is what Wikipedia rapidly evolved towards (and is still evolving). They have successfully leveraged the power of a bottom-up crowdsourced system. But they quickly found they had to add some top-down editorial filters to keep Wikipedia from becoming a constant brawling mess.

Another comparison worth making is the approach to information in Wikipedia and our educational system. Wikipedia correctly perceives their roles as documented the consensus of human scholarship. What things can we claim to know with reasonable confidence, based on some operational rules of transparency and independence? Wikipedia is not the place to debate new or fringe ideas, but to simply reflect those ideas which have already gained a sufficient acknowledgement among appropriate scholars.

That is the exact approach I think public schools should take. They exist to teach consensus scholarship, not give equal time to every fringe idea. Where schools differ is that they are not just a reference of information for students, but also exist to teach students how to think, how to study, and how to be scholars. For that reason students may need to be exposed to fringe ideas, to teach about them and how to evaluate them, but not to teach them as facts or as legitimate alternatives to mainstream scholarship.

For those who espouse fringe ideas, if they want to promote them and to elevate their fringe ideas into the mainstream, there are places to do that. They have to do the hard work of scholarship and convince academics of the value of their ideas. That is a different marketplace of ideas with its own rules.

What happens, however, is that fringe ideas fail in the marketplace of academia and science, and some proponents of those failed ideas then try to create a second life in the public marketplace which has different and often more permissive rules. They try to game Wikipedia, journalists, or the educational system, or they simply market their ideas in books or online.

That is why there needs to be additional rules for good journalism, or for projects like Wikipedia in order to prevent such end-runs around proper scholarship.

The Moon Landing Hoax – Again

neurologicablog Feed - Mon, 11/20/2017 - 4:56am

James Randi has often observed that paranormal beliefs are like “unsinkable rubber duckies.” No matter how many times they are knocked down, they just keep popping back up. That’s because they are not based on facts or logic, but motivated reasoning serving some deeper cultural or emotional need. You can counter them with facts, but that is not addressing the real reason for their existence.

Conspiracy theories are the same. There is a variety of motivations behind them, having nothing to do with the truth. They result partly from hyperactive pattern recognition and agency detection, serving a need for certainty, feeling special, and defending existing narratives from refutation. A well-tended conspiracy theory is like impenetrable armor that can turn away any fact.

The notion that the US never really went to the moon, and that the entire Apollo program was staged for some reason is one such conspiracy theory. Those who promote the moon landing hoax conspiracy theory depend largely on anomaly hunting – looking for anything that they cannot immediately explain, or that looks odd, and then proclaiming that it is evidence for a hoax. So far every one of their alleged anomalies has been shot down.

They claim, for example, that the lighting in photographs from the moon’s surface is uneven, proving stage lighting. Actually, the opposite is true. The unevenness of the shadows is from the unevenness of the surface of the moon itself. But properly analyzed, the photos show that the lighting is, in fact, parallel. This indicates a distant light source, like the sun. To duplicate this effect on earth, while simultaneously duplicating the lack of diffusion (no atmosphere) would have required many bright white lasers, technology that simply did not exist back then. (Lasers were expensive and only available in red.)

So ironically, what the moon hoax conspiracy theorists end up proving is that the moon landing could not possibly have been faked and was therefore real.

All other objections have similarly been dealt with. The movement of the flag was not due to wind, but just inertia (again, no atmosphere to dampen the oscillations). The movement of the astronauts and objects could not be duplicated by simply slowing down the film. Further, you can examine the dust thrown up by the moon rover and show that the thousands of dust particles are moving in moon gravity without an atmosphere.

As many people have pointed out, duplicating all this on Earth would have been more difficult and more expensive than simply going to the moon.

Conspiracy theorists are also good at “just asking questions.” Why can’t we see the moon landing sights with our orbiters? Well, we can. The  Lunar Reconnaissance Orbiter (LRO) has captured stunning pictures of the Apollo landing sites, even showing the footprints of the astronauts and matching records of their missions. Of course this, like all evidence, is easily dismissed by conspiracy theorists as fake and part of the conspiracy (impenetrable armor).

Now we have another claim of evidence of a moon landing hoax, of similar quality to all previous claims. Youtuber, Streetcap1, claims to see a stage hand in the reflection in a visor taken during the Apollo 17 mission. This is another great example of anomaly hunting, looking for anything superficially unusual rather than putting evidence into an appropriate context. You can see the picture above, and go to the link for the video which zooms in further.

With regard to the image of the figure in the visor, it is, essentially, blobsquatch. In other words, it is a blurry image at the limit of identifiable detail. It is enough to be suggestive but not definitive – like most photos of alleged ghosts, bigfoots, and Loch Ness monsters. Some photos are identifiable as fakes, and so might be clear, but mostly they are blobs that a motivated imagination can turn into the cryptozoological creature of choice.

In this case the figure is completely compatible with simply being another astronaut in a space suit. That is, by far, the simplest explanation. But it is blurry and distorted enough that you can imagine, if you are so disposed, a stage hand with long hair and a vest, and not wearing a space suit.

Ironically, as with the other alleged lines of evidence presented by the conspiracy theorists, if anything this is just more evidence against a hoax. Look at the entire reflection in the visor, which is essentially presenting the reverse view of the scene. You will notice the absence of any lighting, cameras, or any of the people necessary to pull of staging that photo on Earth. What would that one lonely “stage hand” be doing just standing there in the middle of the set, anyway?

This is often when many conspiracy claims fall apart, because they require simultaneously that the people pulling off the hoax are brilliant, powerful, and have impeccable attention to detail and yet also are incredibly stupid and careless. So, you would need to believe that they constructed a set of the moon’s surface, impeccably lighted, with simulated regolith, and constructed in such a way that a reflection in the visor does not reveal any cameras or equipment. Meanwhile, one stage hand stands right in the middle of the set while the photo is being taken, and the photo is released without anyone noticing.

It also reveals what often happens when you engage in enthusiastic anomaly hunting – the conspiracy explanation actually causes more and larger anomalies than the one it apparently explains. If you hypothesize that the photo is staged in order to explain the figure in the reflection, that hypothesis causes the bigger problem of why there isn’t cameras and other equipment in the reflection.

When trying to figure out the best explanation it is necessary to consider all evidence and all competing hypotheses to determine which one is most compatible with that evidence. All conspiracy theorists have to do, however, is cast doubt and ask questions. They are not really trying to put forward a coherent theory that stands up to scrutiny. They are just trying to cast doubt on the official explanation, and then declare that there must be a conspiracy. This is similar to science denial, like various forms of creationism. They don’t have to prove a coherent theory of creation, just cast doubt on evolutionary theory and then declare victory.

This latest bit of “evidence” is no different than all the other bits put forward to support a moon hoax theory. It is worthless, and if anything is just more evidence that the moon landing was genuine. That will not stop it from being added to the canon of moon hoax lore.

The Ethics of Head Transplants

neurologicablog Feed - Fri, 11/17/2017 - 4:43am

Newsweek, who has been following the story of Italian Neurosurgeon, Sergio Canavero, now reports: “Human Head Transplants Are About to Happen in China: But Where Are the Bodies Coming From?”

I have already discussed the scientific aspects of this claim. They are highly implausible and I doubt that such a transplant is about to happen at all. If it does I predict it will be a dismal failure, and ethically dubious. First, I have to reiterate, that it is far more accurate to call such a procedure a body transplant. The head donor will wake up with a new body. The body donor is, I suspect, dead.

There are three basic hurdles that need to be overcome in order to have a successful body transplant – the surgical attachment, suppression of rejection, and regeneration of the attached neurological tissue. Given that Canavero is a surgeon, I suspect he is excited about the first issue. He may think he has made some advances because he improved his technique for making the attachment. This was never, however, the primary hurdle.

We are already making great advances with organ transplantation and controlling rejection. However, this is still a huge issue. Donor and recipient have to be closely matched, and lifelong drugs are required. Still, the amount of tissue being transplanted here will be a challenge. It opens up, for the first time, the possible effects of tissue rejection on an entire brain. While this is a significant hurdle, our current treatments mean it is not necessarily a deal breaker (it might be, but research would be needed to see).

The real deal breaker here is the third issue – getting the neurological tissue to regenerate, specifically the spinal cord and various nerves. If you cannot get the head and body to communicate through the spinal cord, you will be essentially creating a quadraplegic – the body recipient will be entirely paralyzed and need to be on a ventilator.

Canavero is claiming that he has farmed out this research to another team, who have made such progress that he can proceed with a transplant. To say I find that hard to believe is an understatement. Such an advance would be truly enormous. There are research teams around the world working on spinal cord regeneration with modest progress – so how has Canavero’s mystery team left them all in the dust, without leaving a paper trail behind in the published literature?

Further, if Canavero’s team has solved the spinal cord regeneration problem (they haven’t, but just hypothetically) using that technology for a body transplant would be ridiculous. How about using it to help the half a million people who suffer a spinal cord injury each year? So either they are lying, or they are holding out such a technology, with is ethically monstrous.

Why China?

Canavero was unable to continue with his research in Italy, so now has moved to China where he claims to have the support of the Chinese government, and further claims he plans to proceed with the first “head transplant” next month. But why China? Newsweek speculates:

It is our suspicion that the authorities in China supporting this procedure are doing so wagering that a successful transplant will demonstrate to the world the dazzling level of technological achievement in the country. Perhaps it will. At a minimum, this procedure reveals that Chinese authorities believe there is no cost too high for raising China’s profile on the world stage.

But it also reveals something else that we think is important: cultural values determine what kinds of scientific research happens and where it happens.

If true, I predict their gamble will backfire. They are essentially backing a crank with impossible claims, and doing so does not make them look like they have advanced technology. Rather, it makes them look gullible and backward. They may think it’s worth the gamble, however. If it fails, that failure will mainly be ignored or discussed on the fringe. If it succeeds, they will stun the world. They will also likely distance themselves from any failure, but fully embrace any success.

Newsweek also brings up another issue. Where are the bodies coming from? China does not have a specific definition of death, and is not in line with the Western world on this issue. This is critical for organ donation. A donor needs to be officially dead, and proper consent had to have been given, either by the donor prior to death, or by their family.

Overall China does not have a great reputation for medical ethics and regulation. This is why they are a major center for fraudulent stem cell clinics, for example. There is potentially much overlap here. Chinese stem cell clinics, selling dubious treatments without proper published evidence to back them up, and without proper transparency, are presented by China as evidence that they are on the cutting edge. In reality they exist to lure desperate Westerners in for fake treatments costing tens of thousands of dollars. Perhaps China is looking to expand into the body transplant market.

In fact China is becoming a center for high tech medical quackery, which makes them a perfect fit for Canavero. I suspect this will play out like other dubious claims of technological advancement (like free energy) – delay, excuse, unsubstantiated claims of success, followed by evasion, then further excuses. Along the way someone will be conned out of money somewhere.

John Oliver Nails Trump

neurologicablog Feed - Thu, 11/16/2017 - 5:10am

In the season finale of Last Week Tonight, John Oliver reviews Trump’s assault on truth and decency. If you haven’t been watching this show, you should give it a try. Not only is it funny and entertaining, but on each episode Oliver does a deep dive on something in our society that is not right and can be fixed. His researchers generally do a great job, and I also think Oliver does a good job of not being gratuitously partisan.

His season-long attacks on Trump may not make it seem that way, but I don’t think they are partisan. I also try to keep my personal politics out of my science advocacy, but I think the problems with Trump transcend politics, ideology, and party. In this last episode for the season, Oliver reviews why this is true.

The real problem with Trump is not that he is Republican or conservative – actually you could argue that he is barely either of those things. It’s not even necessarily that he is an anti-establishment populist who wants to shake things up. The real danger of Trump is that he is an anti-intellectual who has been waging war against journalism, expertise, decency, standards, and any notion of objectivity.

For Trump the only thing that appears to matter is the current struggle in which he is engaged – he needs to achieve what he perceives as victory over any adversary, at any cost. Being honest and respecting knowledge and accuracy doesn’t seem to factor in at all.

As a result Trump is willing to sacrifice the basic fabric that is necessary for a functional democracy. He seems to view democratic checks and balances as nothing but an annoyance and obstacle, so eroding that fabric is just another win for him.

Many people, including many conservatives who have not caved to the insanity, have enumerated the numerous ways in which Trump erodes the shared norms on which our society depends. Oliver’s break down may not be the only way to do it, but it is as good as any. He highlights three strategies Trump uses to erode those standards. Actually, I think referring to anything Trump does as a “strategy” is giving him too much credit. These, rather, are the habits that Trump has adopted which have the effect of undermining our society.

The first is to delegitimize the media. Of course, news outlets are not without fault. They have their own biases and are rife with quality-control issues. Half of what I do on this blog is correct bad reporting about science. But the way to deal with this is to call them on their errors and bias, but in a way that respects the institution and vital role of journalism itself.

Trump doesn’t do this. He attacks entire news organization as “fake news.” The term “fake news” has become a shield against anything Trump doesn’t like or finds inconvenient. When news organization reveal legitimate information, or ask the kind of questions they should be asking of a world leader, Trump’s response is to delegitimize them, denounce them as fake, and even flirt with the idea of banning them from the press room, delicensing them, or “opening up the libel laws” so he can more effectively threaten them.

At the same time he promotes the one news outlet that is essentially functioning as a propaganda arm of the White House. It is clear that Trump would love to have one state media that tow his party line, and ban all other media who would challenge him on anything.

The second method Trump and his defenders use is diversion and distraction, what Oliver calls “whataboutism.” Skeptics will recognize this strategy as the tu quoque logical fallacy – defending one action by pointing to someone else who is engaged in something similar. This is only legitimate to the extent that it points out actual hypocrisy, but it is not a defense of ethically wrong behavior, flawed logic, or bad evidence. The recent allegations about Moore are a great example. Moore is accused, now by multiple women, and supported by accusations that he was banned from a local mall for cruising high school girls, that he had relations with teenage girls, at least one of which was underage. The defense? Well, what about Bill Clinton? Even if you accept as true that Democrats hypocritically gave Clinton a pass on his behavior, that does nothing to excuse Moore’s alleged behavior.

Whataboutism is part of a larger strategy of diversion – to distract from the actual issues with irrelevant dog whistles and appeals to emotion and tribalism. On countless occasions over the last two years I have been in conversations with Trump supporters, asked them about a specific policy point or failing of Trump, and their response was, “What about Hillary Clinton?” They still do it, even though she lost and is now politically irrelevant. The demonization of Hillary was so much a part of their support of Trump, they simply can’t let it go. Trump can’t let it go – he wants to use the Justice Department to punish his political opponent and continue the demonization. It is a convenient distraction whenever anyone has concerns about his blatant incompetence.

Finally, Oliver points out that Trump is essentially a troll. He is the first troll president, who won election by literally trolling his opponents and the media. By troll it is meant that Trump says things not to put forward a serious argument, based in logic and fact, but to have an emotional effect. He does it to upset anyone he perceives as an opponent or obstacle. He even does it to allies, just to keep them in their place.

This provides deniability to anything Trump says. He can never be held to a specific position, because he is generally incoherent. How many times has Trump said something outrageous. Then the media and the public are left scratching their head – it sounds like Trump just said he thinks Neonazis are OK. Did he really just say that? Then his spokespeople take to the airwaves to reinterpret what Trump said, and when Trump is confronted he gives vague and incoherent responses that just muddy the waters even further.

Watching one of his people on talk shows gives me a flashback of reading 1984. It is all newspeak and double talk. Deny, distract, divert, confuse. For anyone who cares about being precise and accurate in communication, it is a nightmare.

The scary thing is that Trump is affecting the baseline norm for society, not just for himself. His behavior is metastasizing. I actually don’t think Trump originated this behavior. Much of it has always been around to some degree, and has been greatly increased by social media. I think Trump is just a social media troll who inherited a marketable name and a lot of money. He found out how to troll his way into politics, at a vulnerable time when we are is social transition.

But he is exacerbating the problem by orders of magnitude. There is an optimistic view, however. Trump is shining a bright light on all the problems with trolling, fake news, and anti-intellectualism. He is also too incompetent to take maximal advantage of his position. I can only hope this will limit the damage he is doing. But hopefully the attention he is bringing to the problem will lead to a backlash, and a rededication to the norms of respect for truth, transparency, and scholarship that are necessary for a functional democracy.

Biology Teachers Honor TIES’ Bertha Vazquez

Each year, the National Association of Biology Teachers (NABT) honors individual teachers for their outstanding contributions to this important field of work. One of those awards is the Evolution Education Award, honoring the teacher whose classroom and community efforts have advanced the public’s accurate (and that’s important) understanding of evolution.

We are proud to tell you that the recipient of the 2017 Evolution Education Award was none other than Bertha Vazquez, the powerhouse middle school science teacher who heads the Richard Dawkins Foundation’s Teacher Institute for Evolutionary Science (TIES). Bertha was given the award at the NABT’s conference last week in St. Louis.

“It’s an honor to be recognized by such a wonderful organization, the National Association of Biology Teachers,” said Bertha. “The success of TIES is the result of the efforts of my fellow TIES Teacher Corps Members. We all recognize the importance of teachers helping teachers.”

As for TIES itself, it has kept up its incredible pace of activity and growth. TIES teacher Gemma Mora-Azuar recently ran a workshop in Houston that trained a record seventy teachers. That same weekend, TIES workshops took place in Columbia, South Carolina; Santa Barbara, California; and Panama City in Florida.

Congratulations to Bertha and all the great teachers powering the work of TIES.

 

The House GOP Budget’s Church-State Sneak Attack

The wall between church and state is the fortification that keeps our democracy from collapsing into theocracy, and the religious Right is always looking for ways the breach the wall where they think it weakest. The Johnson Amendment, to belabor this siege metaphor, is akin to a long-range weapon along the parapets of the wall, archers let’s say. It’s a part of federal law that forbids tax-exempt nonprofits (such as churches and the Center for Inquiry) from endorsing or opposing candidates for political office. Though it has proven to be a difficult law to enforce properly, the very presence of the archers has kept most of the enemy at bay.

That’s all changed. While those bows and arrows dissuaded most individual churches from engaging in electioneering (and indeed the majority of religious organizations support the Johnson Amendment), a well-funded and maniacally obsessed army of hard-right religious groups is not so easily spooked. Hurling massive payloads of political influence and lobbying dollars from their cross-shaped trebuchet, they aim to knock the archers of the Johnson Amendment from their perch. If they go down, the entire wall will not collapse, but gates of another kind would certainly fly open: the floodgates of political cash, flowing directly toward those churches that wish to become de facto political action committees for religious-Right candidates. (Sort of like a freelance cavalry? This metaphor may be going too far.)

A huge volley was flung toward the wall at the beginning of this month, when the House GOP released their proposed tax reform bill, which includes a provision revoking the restrictions of the Johnson Amendment for churches, allowing these institutions to openly support candidates for office. Donations to these churches would remain tax-exempt, and churches have tremendous leeway when it comes to what they use their donations for and how much they reveal about it to the public. That’s how these churches then become unofficial arms of a given candidate’s campaign.

Clergy, church employees, and members of congregations have never been prohibited from speaking their minds and supporting the candidates of their choice, despite the shouts and complaints of the religious Right and their allies in Congress and in the White House. The Johnson Amendment limits the activities of the institutions themselves, not individuals.

So it’s up to us to shore up this crucial part of the wall of separation. Luckily, most religious organizations and most of the American people agree with us: Churches shouldn’t meddle in elections. We put out an action alert to make it easy for you to contact your representatives and tell them that you want to keep those defenses strong.

News from the CFI Community

Paul Ryan’s Prayer Fallback: Sad!

After the horrific shooting massacre that left twenty-six dead in a Texas church, our leaders reverted to many of the same arguments and platitudes that almost always follow tragedies like these. While many are once again driven to take actions that would prevent further needless slaughters, others warn us that “now is not the time” and default to the now-cliched “thoughts and prayers.”

But as secularists and skeptics, we know that prayers are never enough. Certainly individuals can find comfort in their prayers, and we hope that everyone affected by these tragedies can find whatever means they can to help themselves and their loved ones heal. But prayer is not a solution to the crises that we face. It couldn’t possibly be.

But try telling that to the Speaker of the House of Representatives. On Fox News’s The Ingraham Angle, Speaker Paul Ryan berated those who have criticized him for solely relying on prayer and expressions of piousness whenever real-world problems overwhelm us. He proclaimed his “disappointment” with the “secular left,” saying how “sad” it is that we “don’t understand faith.” And then he told Ingraham:

And it is the right thing to do, is to pray in moments like this because you know what? Prayer works. And when you hear the secular left doing this thing, no wonder you’ve got so much polarization and disunity in this country when people think like that.

There’s a lot wrong with those sentences, not least of which was the idea that secular Americans who want reality-based solutions to our nation’s problems are somehow responsible for political polarization and division.

But more importantly, Ryan made the claim that “prayer works.” In our official statement, we reminded the Speaker that in fact there is no evidence that praying has any effect on earthly events, apart from an individual’s personal solace from the practice. Prayer certainly won’t fix the national emergency of gun violence.

As our president and CEO, Robyn Blumner, said, “Speaker Ryan’s imperative is to use his influence and power as our highest ranking legislator to create real, positive change that keeps all Americans safe while upholding our nation’s highest ideals. That he chooses this moment to belittle secular Americans, or Americans of any religious affiliation, is what is truly sad.”

Go check out our action alert and tell the Speaker that actions speak louder than prayer.

 

Some Justice—Maybe—for Avijit Roy

Four years ago, the Center for Inquiry formed a bond with a brilliant writer and science communicator in Bangladesh, Avijit Roy. Several atheist bloggers had been arrested at the time for “hurting religious feelings,” and we coordinated with Avijit to organize protests in locations around the world to demand their release.

In 2015, Avijit was murdered. He and his wife Rafida Bonya Ahmed were ambushed by Islamist militants at a book fair in Dhaka. Bonya suffered terrible injuries, and Avijit was hacked to death. It was a killing that heralded a wave of such murders in the months and years following, targeting secularist writers and activists. As a way to honor the memory of our friend Avijit Roy, and to support the cause of free expression, the Center for Inquiry established Secular Rescue, an initiative to provide assistance and relocation to activists whose lives are threatened by religious extremists. More than thirty people have been helped through this program so far.

Last week it was reported that one of the men believed to have participated in the attack on Avijit and Bonya has been arrested by Bangladeshi authorities. Abu Siddiq Sohel, allegedly a member of the al Qaeda–linked organization Ansar Ullah Bangla Team, reportedly told police that he had been a part of the attack.

We have no way of confirming the accuracy of these reports. However, we do have more than sufficient reason to be skeptical of any official news surrounding the murders of secularist activists, as the government of Bangladesh has been overtly hostile toward the victims of these attacks, blaming them for their own deaths and denouncing their writings. We declared the official response to the killings “appalling” and called upon the authorities to defend free expression rather than foment anger and hate.

For the sake of Avijit’s family and friends, secularist writers in Bangladesh, and for the sake of justice, we truly hope that all of Avijit’s killers will be apprehended and fairly tried. We’ll be watching these events closely as they develop.

 

Secular Rescue Success Story: Lubna Ahmed

Because of the nature of CFI’s Secular Rescue program, though we assist secularist writers and activists whose lives are threatened by extremists, it’s not always possible to publicly celebrate its successes. Even after someone has been relocated out of immediate harm’s way, it may be necessary for them to maintain a low profile for the sake of their own safety or that of their family.

How rewarding it is, then, when one of these brilliant and courageous people can step into the spotlight, tell their story, and continue to fight for their cause. On Monday, Lubna Ahmed, a human rights activist and chemical engineering student from Iraq, was the guest on The Rubin Report, where she eloquently described her struggle as an atheist living under threat in an ultra-conservative Islamic society.

“[The Center for Inquiry is] helping me, they supported me … They supported my case with the lawyers,” she told Rubin, when asked about the financial and legal assistance the Secular Rescue program provided. “I’m very grateful to Mr. Richard Dawkins. He takes his words into actions, not like others, because he sees that it’s very important to save people who are like me.”

We do believe in Lubna and all those who are striving to advance reason and secularism in the places most hostile to them. And we’ll keep doing all we can to help.

 

CFI Highlights on the Web

On Halloween, the Science Channel show Strange Evidence provided an example of how not to handle actual experts on the subject of extraordinary claims. CFI’s Joe Nickell and Tom Flynn were both asked to examine video purported to be evidence of Bigfoot, but as Joe explains in his post, the video he and Tom saw was not what they aired on the program, and in neither video was there proof of any Sasquatch to be found.

Joe has a lot more of substance to offer on this cryptozoological subject from his article in Skeptical Inquirer on the evolution of the Bigfoot myth, how it borrows and adapts from various cultures’ beliefs and legends, and has been molded by the “shrinking” of the planet.

Joe also recounts his visit to a Las Vegas–area saloon after CSICon last month, where legends tell of ghosts that haunt every part of the establishment, including the restrooms. As you could probably guess, Joe concludes, “There is only one kind of spirits at the Pioneer, the kind poured into a glass.”

Tamar Wilner does a true service for consumers of media, as she teases out the various strains of misinformation in the news media, most of which is being categorized as “fake news,” which she says “is a wooden mallet. It’s blunt. It can only smash, not carve, pluck, or hold up for inspection. The more we use it, the more dulled we all seem to its effects.”

Can chiropractors cure diabetes? No, but it makes for good marketing copy. William London looks at the various gimmicks that are bandied about to promote chiropractic, including the claim that diabetes can be “reversed” by chiropractors.

Consistently enlightening are Ben Radford‘s correspondences with those who vehemently disagree with his skeptical take. Here, he delicately engages in an exchange with someone who is sure that psychic powers exist (and something about Thomas Edison having been thought of as a “lunatic” in his day).

From Free Inquiry’s special issue on blasphemy in art, Bruce Adams tells of his own development as a blasphemous creative artist, and how his aim is to irreverently confront difficult issues through his art. The blasphemy is just a bonus.

In celebration of the anniversary of Carl Sagan’s birth, Inverse highlights an excerpt from a piece written by Ann Druyan about her life with Sagan for Skeptical Inquirer in 2003. “I don’t think I’ll ever see Carl again,” she wrote. “But I saw him. We saw each other. We found each other in the cosmos, and that was wonderful.”

And of course, you can keep up with news relevant to skeptics and seculars every weekday with The Morning Heresy.

SHERMER SHREDS Mass Public Shootings & Gun Violence: Part I

At 59 dead and over 540 wounded, the Las Vegas massacre that took place on October 1, 2017 is now the worse mass public shooting in U.S. history.

As is usually the case with such gun-related tragedies, within hours social media and political punditry was abuzz with talk of gun control and Second Amendment rights, with both the left and the right marshaling their data and arguments. The two most common arguments made in defense of gun ownership are (1) self protection and (2) as a bulwark against tyranny.

In this video, Michael Shermer “shreds” these ideas with skeptical scrutiny.

Sigmund Freud (1926). Photo by Ferdinand Schmutzer [Public domain], via Wikimedia Commons

In this week’s eSkeptic, Margret Schaefer reviews Freud: The Making of an Illusion, in which its author, Frederick Crews, convincingly argues that Freud constructed psychoanalysis on a fraudulent foundation. How did Freud convince so many people of the correctness and the profundity of his theory?

The Wizardry of Freud

by Margret Schaefer

“Clear evidence of falsification of data should now close the door on this damaging claim.”

The above is from a 2011 British Medical Journal article about Andrew Wakefield, the British physician whose “discovery” of a link between vaccination and autism fueled a world wide anti-vaccination movement. Since its publication in 1998, the paper’s results were contradicted by many reputable scientific studies, and in 2011 Wakefield’s work was proved to be not only bad science but a fraud as well: a British court found him guilty of dishonestly misrepresenting his data, removed him from the roster of the British Medical Society, and disbarred him from practice.

In his new book, Freud: The Making of an Illusion, Frederick Crews presents a Freud who was just such a fraud and who deserves the same fate. This is not the first time that Crews, a bona fide skeptic whose last book, Follies of the Wise: Dissenting Essays (2007), was reviewed in the pages of this journal, has written critically about Freud. Crews had been drawn to psychoanalysis himself (disclosure: this reviewer was, too) in the 1960s and early 1970s when, along with the late Norman Holland, he pretty much created the field of psychoanalytic literary criticism. But a prestigious fellowship to the Stanford Center for Advanced Study in the Behavioral Sciences (he was a professor of English at UC Berkeley at the time) gave him time to delve deeper into Freud, and convinced him instead that psychoanalysis was unscientific and untenable. Since then he has contributed to the growing skeptical scholarly and historical scholarship on Freud.

Psychoanalysis is not only pseudoscience (as most philosophers of science agree, though for different reasons), but “the queen of pseudosciences”.

Philosophers of science have indicted key concepts of Freud’s psychoanalysis such as “free association,” “repression,” and “resistance” as circular and fatally flawed by confirmation bias. Historians have tracked down the actual patients whose treatment served Freud as evidence for his theories and have sought to place Freud and his theories in the historical and cultural context of his time.

The Wizardry of Freud

Skeptic.com feed - Tue, 11/14/2017 - 10:30am

“Clear evidence of falsification of data should now close the door on this damaging claim.”

The above is from a 2011 British Medical Journal article about Andrew Wakefield, the British physician whose “discovery” of a link between vaccination and autism fueled a world wide anti-vaccination movement. Since its publication in 1998, the paper’s results were contradicted by many reputable scientific studies, and in 2011 Wakefield’s work was proved to be not only bad science but a fraud as well: a British court found him guilty of dishonestly misrepresenting his data, removed him from the roster of the British Medical Society, and disbarred him from practice.

In his new book, Freud: The Making of an Illusion, Frederick Crews presents a Freud who was just such a fraud and who deserves the same fate. This is not the first time that Crews, a bona fide skeptic whose last book, Follies of the Wise: Dissenting Essays (2007), was reviewed in the pages of this journal, has written critically about Freud. Crews had been drawn to psychoanalysis himself (disclosure: this reviewer was, too) in the 1960s and early 1970s when, along with the late Norman Holland, he pretty much created the field of psychoanalytic literary criticism. But a prestigious fellowship to the Stanford Center for Advanced Study in the Behavioral Sciences (he was a professor of English at UC Berkeley at the time) gave him time to delve deeper into Freud, and convinced him instead that psychoanalysis was unscientific and untenable. Since then he has contributed to the growing skeptical scholarly and historical scholarship on Freud.

Philosophers of science have indicted key concepts of Freud’s psychoanalysis such as “free association,” “repression,” and “resistance” as circular and fatally flawed by confirmation bias. Historians have tracked down the actual patients whose treatment served Freud as evidence for his theories and have sought to place Freud and his theories in the historical and cultural context of his time. Crews—to his own surprise—became well known as a major, if not the major, critic of Freud in the public eye because of a series of articles he published in the New York Review of Books in the 1990s. For Crews is that now all too rare and rapidly disappearing creature—the public intellectual—who is able to explain and make accessible an otherwise unwieldy amount of erudite scholarship in clear, elegant, and jargon-free prose. Defenders of Freud have sought to discredit him as a “Freud basher,” thereby continuing the (not so honorable) tradition that Freud began of questioning the motives of a skeptic and attributing it to “resistance” instead of answering his objections.

This is precisely one of the reasons that in previous books Crews has said that psychoanalysis is not only pseudoscience (as most philosophers of science agree, though for different reasons), but “the queen of pseudosciences,” because it is the only one that incorporates within its theory an explanation of why some people refuse to believe it, i.e. “unconscious resistance” which needs to be explained by Freud’s own ideas and methods—a most brilliant and masterful way of disarming criticism.

His new book, a biography of the first half of Freud’s life, with intensive focus on the period 1882–1900, examines the crucial years in which Freud was creating his “science of psychoanalysis,” which culminated in his Studies on Hysteria, 1895 and The Interpretation of Dreams, 1900. This time in Freud’s life has been somewhat neglected by Freud’s biographers for many reasons, including lack of sufficient available biographical information, but also because in these years Freud developed a theory of neurosis that he later said he abandoned. But Crews argues that all the principal concepts on which psychoanalysis rests were constructed at this early time. His logic is that if the roots of a tree are not sound, then the crown, no matter how beautiful and different from the roots, cannot be healthy. And recently a treasure trove of new data about Freud during this period has been released from censorship: the complete correspondence between the young Sigmund Freud and his fiancée Martha Bernays during the long four and a half years of their engagement, 1882–1886.

This correspondence, which consists of an astounding 1539 letters in all, had been concealed from public view for some 60 years. Only a very small portion—97 letters, or 6.3% of them—had been previously published, and those in expurgated form. Their importance is attested to by the fact that Anna Freud, his daughter, kept them private at her house in London instead of depositing them in the Freud Archive along with the rest of Freud’s papers after her father’s death in 1939. It was not until her own death in 1982 that her heirs finally did deposit them in the Freud Archive—but even then it was with the stipulation that access to them be restricted until the year 2000. Why was this correspondence hidden for so long? Their content makes it clear why: they don’t paint a flattering portrait of Freud. A reading of these letters after they became available on the Library of Congress website spurred Crews to write this book, as it confirmed to him all the suspicions about Freud’s motives and manner of working that he and others had raised before but had had to remain somewhat speculative: the fraudulent and pseudo-scientific evidential base on which psychoanalysis rests.

Despite its nearly 700-page length and 22 pages of footnotes, Crews’ book is divided into sections with witty titles such as “Sigmund the Unready,” “Tending to Goldfish,” and “Girl Trouble” and is thoroughly absorbing and highly readable. He begins with an examination of Freud’s family history and early education, detailing the reasons why Freud was “unready” to undertake the study of medicine, and then focuses on Freud’s “First Temptation”: cocaine. Freud’s enthusiastic endorsement—and use of—cocaine, Crews contends, had a much greater consequence for the theory of psychoanalysis than is officially recognized. It was not a soon-to-be-discarded “youthful indiscretion,” as Ernest Jones called it in his official 1957 biography of Freud, for Freud continued to use cocaine regularly, almost daily, not just occasionally, for some 15 years. Crews details Freud’s early experiments with the substance, and documents his disastrous attempt to help ease his best friend Fleischl’s withdrawal from morphine addiction by means of injections of cocaine. Meant as a kindness, it became the opposite, as Freud ignored every sign that it was not working and was blatantly harming his friend instead. Later, Freud dishonestly claimed to have cured Fleischl, when in fact his friend tragically deteriorated while undergoing Freud’s treatment, and finally died in great pain with two addictions instead of one: morphine and cocaine. The details of what happened to Fleischl are gruesome to read, and Crews sees Freud’s tenacious clinging to a pet theory and ignoring any evidence to the contrary, no matter how devastating, as characteristic of him throughout his life from then on.

As Freud wrote Martha while recommending it to her, he used cocaine to alleviate his many physical and emotional symptoms, which ranged from headaches, stomach aches, and sciatica to recurring depressions and intermittent “bad moods” punctuated by periods of elation. It consoled him for his loneliness in Paris while studying with Charcot, and gave him the self-confidence that he mostly lacked at this time. Most importantly for the creation of his psychoanalysis, he used it to overcome his writer’s block. Hence he was “under the influence” while he was thinking, writing, and creating the theories of psychoanalysis. Crews develops the intriguing notion that Freud had a “cocaine self” that permitted him to misrepresent and exaggerate the flimsy evidence he did have for his theories—and to manufacture evidence when none existed. Freud as a student had been a “studious, ambitious, and philosophically reflective young man, trained in rigorous intuitivism by distinguished researchers,” as Crews acknowledges. But in the early 1880s he changed into someone so arrogant and overweeningly ambitious and grandiose, so absolutely and unaccountably convinced of his theory of the sexual etiology of hysteria that he didn’t hesitate to stoop to dishonesty and fraud to try to prove it.

Psychoanalysis is not only pseudoscience (as most philosophers of science agree, though for different reasons), but “the queen of pseudosciences”.

Cocaine is notoriously known to induce feelings of supreme self-confidence, elation, and grandiosity in the user, to the point that facts and reality no longer matter. It also heightens sexual feelings and fantasies and is often used as an aphrodisiac for that reason, as Freud was well aware, using it for that purpose himself. (More than once in his letters we find Freud telling Martha that he feels like a “sexual giant.”) And Crews argues that Freud’s cocaine use also explains his exaggerated focus on sexuality as the ultimate cause of all neuroses.

Freud’s theory at the time, in brief, was that sexual seduction (molestation) in childhood, usually by fathers, which was “repressed,” i.e. not consciously remembered, was the “invariable,” “only,” and “exclusive” cause of all hysteria—in fact, of “all the neuroses”—as he announced in a paper he gave to a group of his peers in 1896. In that paper he presented as evidence 13 cases that he said he had successfully cured. No matter that the group’s chairman, Richard von Krafft-Ebbing, called Freud’s theory “a scientific fairly tale”—Freud rejected this judgment as due to his being an “ass” and a conventional prude—surely hard to believe of someone like Krafft-Ebbing, the foremost expert in pedophilia in the world at that time, and a man from whom Freud actually took a number of ideas (without giving him credit). Even more shockingly, Freud later admitted to his friend, confidant, and collaborator Wilhelm Fliess, a Berlin physician, that these 13 cases didn’t exist at all—he had just made them all up.

Freud believed in what has come to be called his “seduction theory of hysteria” for many years until he famously “changed his mind” about what it was that his patients had “repressed.” Although it is unclear exactly when he officially made this change (it was not until 1909 that he called the Oedipus complex the central complex of the neuroses), he privately confessed to Fliess in 1897 (a few months after presenting his fraudulent paper) that he had not actually been able to “conclude a single case” of analysis so far, i.e. that his treatments had not produced a single cure. In fact, he had not even been able to induce any patient to agree with him and “remember” such abuse consciously, even though he had exercised extreme pressure to get them to do so, including massage, “head pressure,” and drugs to put them in a more suggestible mood when verbal suggestion didn’t work (of course he had attributed this to their “resistance” and “repression”) This change of mind has long been celebrated as the beginning of “true psychoanalysis,” as it placed the cause of hysteria away from the external world and into the internal psychological world of his patients: they were not repressing memories of actual sexual molestation, but rather their own childhood sexual fantasies and desires that they had unconsciously attributed to their fathers. However, Crews shows that Freud had no more evidence for his second theory (in fact, less, as it was empirically not even potentially verifiable) than he did for his first one, and continued to use all the (circular and self-invented) concepts with which he had tried to “prove” the first theory, e.g. “repression,” “free association,” and “resistance,” all of which have meaning only in Freud’s own system.

If his new theory was no more empirically based than his first, how did Freud actually come up with his ideas of the etiology of hysteria? Crews takes his clue from the fact that Freud saw himself (and other family members, especially one of his sisters) as suffering from an hysteria exactly like those of his patients, and that what he represented as his empirically based “science of psychoanalysis” were actually his own—real or imagined—childhood sexual experiences. Crews’ exposition of what in Freud’s biography led him to his theories makes for interesting reading indeed. In the end, Crews demonstrates that Wilhelm Fliess, who at their last actual meeting in 1900 accused Freud of merely reading the contents of his own mind into that of his patients, was right. What this means is psychoanalysis is based on a case of one—Freud himself. That is, Freud took himself as representative of all people in all times and in all cultures—surely a supremely grandiose, narcissistic—and preposterous—idea.

This is just a thin slice of what else there is in this riveting and rewarding book. One chapter is devoted to Freud’s rather unsuccessful stay in Paris in the winter of 1885-86 observing Charcot’s treatment of hysterics at Paris’ famous Salpêtrière. Freud idealized Charcot, and never questioned the obvious artificiality of Charcot’s sexualized “theater of hysteria” that entertained the aristocratic audiences he invited to watch it, although others there at the same time as Freud saw through the charade, correctly seeing Charcot’s use of hypnosis as an extreme form of suggestion. Instead, he took over Charcot’s theory of the origin of hysteria wholesale. Charcot’s theory of hysteria died with Charcot in 1893, since by then it had become obvious that the great doctor had gone astray in his enthusiastic use of hypnotism. But Freud took no notice and elaborated Charcot’s method of using hypnosis on his patients after he returned to Vienna—with no success, as Crews details in sometimes hair-raising detail. The case of Bertha Pappenheim, considered to be the foundational case of psychoanalysis, is paradigmatic of the gulf between the reality of her treatment and its later reporting. Although she was Breuer’s patient from 1880–1882, Freud collaborated with him throughout the case, and referred to this particular case, “Anno O,” later more than to any of his own cases. This supposedly “successful cure” showing how hysterical symptoms could be cured by cathartic “talking” was a complete failure instead. After two years and a thousand hours of therapy (!) by Breuer, Pappenheim was worse, not better. And all the while she was supposedly cured of her symptoms by talking freely until she found their point of origin (the famous “chimney sweeping” that Freud took from her and later called “free association”) Bertha was being given large quantities of mind-altering drugs such as chloral hydrate (a “hypnotic” chemical that today is often used as a “date rape” drug) and morphine—drugs whose side effects and withdrawal symptoms in turn were often misinterpreted by the two as the very “hysterical symptoms” she needed to have cured (thus giving new meaning to Karl Kraus’ assessment of psychoanalysis as “the disease it purports to cure”). The quantities used on her were such that five weeks after her discharge as “cured” she had to be admitted to a psychiatric hospital, still symptomatic, and needing be detoxed—a truth that Freud and Breuer failed to mention when they wrote the case up 13 years later. And so it went with many other patients, e.g. Anna von Lieben, whom Freud in 1897 called his “principal client” and “instructress,” Ida Bauer (“Dora”), and Emma Eckstein, whose treatment, which almost killed her and resulted in her severe facial disfigurement, qualifies as out and out medical malpractice.

Crews’s book takes us up through Freud’s life and ideas until his Interpretation of Dreams in 1900. The idea that dreams have meaning is an old folk belief which is true on the face of it, as people do dream about matters of concern to them, but Freud’s elaborate dream theory gives that belief a pseudoscientific gloss, as he invented a complicated theory of dreams that attributed extraordinary intellectual and linguistic abilities to a supposed “dream censor” in our minds. It is pseudoscientific because—to give just one obvious reason—Freud’s interpretive scheme allowed for a symbol to mean either itself, its opposite (“You say it’s not your mother? Aha! It is your mother”) or anything else at all (displacement), with no way to determine which interpretation is correct, or even likely.

In the later part of his book, Crews also takes up the matter of Freud’s relationship with his sister-in-law Minna, the younger sister of Martha, who came to live with the Freuds in Vienna after the death of her fiancée in the mid-1890s. Crews finds the admittedly circumstantial evidence that she and Freud had a long-term affair too strong to ignore. (And what evidence can there be in something of this sort but circumstantial?) But he does not find this matter merely titillating. Crews argues that Freud’s closeness to Minna had an influence on his elaboration of psychoanalysis. As early as the mid-nineties, she supplanted Wilhelm Fliess as his confidant after that relationship ended in bitterness, as unlike Martha, she took a lively interest in his work, and helped him write his books and papers. Crews argues that she may have helped turn Freud away from whatever scientific and empirical values he still ostensibly held towards extremes of speculation such as spiritualism and telepathy. (At one point Freud actually claimed that what passed between the analyst’s and his patient’s “unconscious” happened by means of telepathy.)

Freud took himself as representative of all people in all times and in all cultures—surely a supremely grandiose, narcissistic—and preposterous—idea.

If, as Crews convincingly argues, Freud constructed psychoanalysis on a fraudulent foundation, how did he convince so many people of the correctness and the profundity of his theory? And not just his enthralled followers over whom he presided like the guru of a cult, excommunicating all apostates, but also many of us over many subsequent decades? One reason for Freud’s wizardry in doing this, Crews suggests, is Freud’s rhetorical mastery and guile, including his heart-warming protestations of modesty and scientific rigor. Crews, after all originally a literary critic, notes that the narrative structure of Freud’s case histories and his Interpretation of Dreams was that of a suspenseful detective story in the manner of Arthur Conan Doyle, one of Freud’s favorite authors (Freud himself admitted—in supposed surprise—that his case histories read more like short stories). In The Interpretation of Dreams, for example, Freud induces his reader to identify with him and join him in a quest he structured as a difficult and unsparingly honest introspective journey leading to that heart of darkness, the source of all dreams—“the Unconscious.” (Not for nothing was Freud awarded the Goethe prize for literature in Germany in 1936.) So he was creating “literature,” as some who still idealize the founder today argue and actually see as a virtue, claiming that psychoanalysis is therefore a “hermeneutic” rather than an empirical “science,” one conveniently not subject to empirical rules of evidence. True, “literature” does not have to be attuned to empirical reality—it’s “truth” lies in a different realm—but a theory of mind and a “science,” especially one applied to the (costly) treatment of suffering patients in the actual world, does.

I can’t help but add that one reason that Crews’ book succeeds as a readable and compelling book is the same one to which he attributed a good deal of Freud’s success: he, too, is an eloquent and passionate writer who has here constructed as enthralling a detective story as any of Freud’s. He, too, becomes Sherlock Holmes, the objective, erudite, and supremely rational sleuth who relentlessly tracks down hidden clue after clue—which leads him inexorably to only one possible verdict: Freud is guilty of fraud as charged. Except—and this is the big difference—Crews provides ample documentation and evidence for what he says, whereas Freud only pretended to do so.

Is any of this still important today, when psychoanalysis has effectively been banished from the mainstream professions of psychiatry and psychology for its lack of efficacy? Today even basic Freudian terms such as “hysteria” and “neurosis” have been excised from the DSM, the bible of psychiatric practice. But Crews argues that psychoanalysis still remains culturally pervasive and that Freud’s ideas, though proven pseudoscientific many times, persist and are still capable of exerting harmful influence in the real world. A recent example was the widespread “recovered memory” movement of 1980s and 1990s that Crews detailed in his eye-opening book of 1995, The Memory Wars. This movement, which still has hangers-on today, destroyed the lives of many families, including that of the daughters who accused their fathers of sexually molesting them in childhood on the basis of a therapist’s unearthing their “repressed memories” of sexual abuse, and jailed a number of falsely accused men. It was obviously a revival of Freud’s original theory of neurosis, in which a therapist convinced of this theory subtly or not so subtly—as was clearly demonstrated in later lawsuits—suggested this to their patients, just as Freud himself did.

Crews hopes that by proving that Freud’s creation of psychoanalysis was a fraud he will finally help “close the door” on this “damaging claim.” Will it? Alas, exposure as a fraud does not seem to deter belief: in the U.S. a large fraction of the population still believes in Wakefield’s vaccination-autism theory, and in 2015, anti-vaccination groups in California actually recruited the discredited Wakefield himself to come to their state and head their campaign against the state legislature’s effort to pass a pro-vaccination law protecting school children.

But “the still small voice of reason”—to quote Freud himself in another context—will, hopefully, prevail in the end. Anyone who reads Crews’ new book with an open mind will come away thinking that while Freud was indeed a highly imaginative thinker and an accomplished, eloquent writer—he was also a fraud and a huckster, a narcissistic con-man of overwhelming ambition, hungry equally for fame and fortune, who succeeded by means of deceptive propaganda and rhetoric in being the “conquistador” that he longed to be. But at end of the royal road to Freud’s Unconscious there is finally only the Wizard of Oz.

Fact-checking on Facebook

neurologicablog Feed - Tue, 11/14/2017 - 4:55am

Last year Facebook announced that it was partnering with several outside news agencies, the Associated Press, Snopes, ABC News, PolitiFact and FactCheck.org, to fact-check popular news articles and then provide a warning label for those articles on Facebook. How is that effort working out?

According to a recent survey, not so well. Yale researchers Rand and Pennycook found only tiny effects overall, and it’s possible there is a net negative effect from the warning labels. Some people just ignore the labels. Perhaps more significant, however, is the fact that fake news articles that were missed by the fact-checkers were more likely to be believed as real because they lacked the warning label. The fact-checkers could not possibly keep up with all the fake news, so they were overwhelmed and most of the dubious content not only made it through the filters, but benefited from a false implication of legitimacy.

Further, the Guardian reports that this arrangement between Facebook and these news outlets compromise the ability of those news outlets from being a proper watchdog on Facebook itself. If their journalists are being paid by Facebook to fact-check, then they have a conflict of interest when reporting on how Facebook is doing. This conflict is exacerbated by the fact that news organizations are hard-up for income, and could really use the extra income from Facebook.

So it seems that the fact-checking efforts of Facebook were insufficient to have any really benefit, and may have even backfired. Warning labels on dubious news articles may be the wrong approach. It’s simply too easy to foil this protection by overwhelming the system. You could even deliberately flood Facebook with outrageously fake news stories to serve as flack and provide cover for the propaganda you really want to get through. In the end the propaganda will be even more effective.

The inherent problem seems to stem from the difference between a pre-publication editorial filter and a post-publication filter. Traditional journalism has editors and standards, at least in theory, that require vetting and fact-checking prior to a story being published. Outlets had an incentive to provide quality control in order to protect their reputation.

Of course tabloids also have a long history. They take a different strategy – abandoning any pretense to journalistic integrity, and simply spreading outrageous rumors or fabricated “infotainment.” At least it was relatively easy to tell the difference between a mainstream news outlet and a tabloid rag, although there is more of a spectrum with the lines blurred in the middle.

No one would seriously claim that this system was perfect. News organizations have their editorial biases, and they had a lot of control over what became news. Biases tended to average out over many outlets, however. The big concern was over consolidation in the media industry, giving too much power to too few corporations.

Social media has now upended this system. There is now, effectively, no pre-publication editorial filter. The infrastructure necessary to own and operate a news outlet is negligible, and social media creates a fairly level playing field. It is an interesting giant social experiment, and I don’t think we fully know the results.

What this means is that ideas spread through social media mostly according to their appeal, rather than due to any executive decisions made by gatekeepers. There are still power brokers – people who have managed to build a popular site and have the ability to dramatically increase the spread of a particular news item. That, now, is the name of the game – clicks, followers, and likes. This equals power to spread the kind of memes and news items that will generate more clicks, followers, and likes.

The free-market incentive, therefore, is for click-bait, not necessarily vetted quality news. Quality is still a factor, and will give an article a certain amount of clicks. My perception is that there are multiple layers of information on social media. There are subcultures that will promote and spread items that appeal to them. They may appeal to them because they are high-quality, or because they are genuinely entertaining. Or they may appeal because they cater to a particular echochamber or ideology.

So, if you love science, you can find quality outlets for science news and analysis. Within these subcommunities, quality may actually be a benefit and the cream does rise to the top.

But sitting on top of these relatively small subcommunities is the massive general populace, which rewards memes and clickbait. That is the realm of fake news and cat videos – entertaining fluff and outrageous tabloid nonsense. This realm is also easily exploited by those with an agenda wishing to spread propaganda – click-bait with a purpose.

Facebook, as the major medium for this layer of fake news, now faces a dilemma. How can and should they deal with it? The outsourced fact-checkers strategy is, if the recent survey is accurate, a relative failure. So now what?

I feel we can do better than to just throw up our hands and let this new system play itself out. Sometimes market forces lead to short term advantages but long term doom. Can our democracy function without a well-informed electorate? Can our electorate be well-informed in an age of fake-news? The entire situation is made worse by the fact that the very concept of fake news is used to further spread propaganda, to delegitimize actual journalism and dismiss any inconvenient facts.

Can we properly function as a society if we don’t at least have a shared understanding of reality, at least to the point that there are some basic facts we can agree on? Recent history does not fill me with confidence.

I don’t have the solution, but I do think that the large social media outlets should take the problem seriously and continue to experiment. Overall I think we need to find the proper balance between democracy of information, transparency, and quality control. Right now the balance has shifted all the way toward democracy, with a massive sacrifice of transparency and quality control. I don’t think this is sustainable.

There are, of course, things we can do as individuals – such as supporting serious journalism, and not spreading click-bait online. Everyone needs to be more skeptical, and to vet news items more carefully, especially before spreading them to others. But this is a band-aid. This is like addressing the obesity crisis by telling everyone to eat less and exercise.

We need systemic change. It’s an interesting problem, but there are certainly ways to at least improve the situation.

Raccoons Are Smart But Not Good Pets

neurologicablog Feed - Mon, 11/13/2017 - 4:54am

Animal intelligence is fascinating for a number of reasons, not the least of which is that it forces researchers to think carefully about what intelligence is. The comparison might also provide a window into what constitutes human intelligence in particular.

There is no question that humans have intellectual capabilities that no other species has. However, some animals are smarter in certain ways than you may imagine. Certain birds, like corvids (jays and crows) have demonstrated significant problem solving capability, for example. Researchers are also finding that raccoons may be even smarter than we suspected.

One paradigm of animal intelligence research is known as the Aesop’s Fable test, based on the the story of the thirsty crow. In this tale a thirsty crow came upon a tall pitcher with water at the bottom, but it could not reach down the long neck to the water. So it dropped stones in the pitcher to raise the water level until it could reach. This behavior demonstrates creative problem-solving and some basic understanding of cause and effect. Corvids have the ability to pass this test – they can figure out how to use objects to raise the water level to gain access to water or food.

A recent study performed the same test on raccoons. They were given access to a long tube with marhmallows floating lower down, too low for them to reach. First they were shown how dropping stones would raise the water level. Two of eight raccoons tests were then able to use this effect to gain access to the marshmallows. Statistically this is not as good a performance as corvids, but at least some raccoons are smart enough to pass the test.

One additional raccoon gained access to the marshmallows, however. They figured out how to grip the top of the tube and then rock back and forth to know the tube over. The researchers had specifically designed the tube so it could not be knocked over, but the raccoons essentially broke the apparatus. This is interesting because it shows that animals may have particular skills or predilections that they will use to their advantage. Knocking over the tube was a very “raccoon” solution.

The researchers also went further. In a follow up experiment they exposed the raccoons to the same setup and gave them access to floating and sinking balls. The sinking balls would raise the water level, while the floating ones were “non-functional” – or so the researchers thought. Again the two smart raccoons performed well, and they figured out that by dropping floating balls on the water they could then push them down, splashing water and marshmallow up along the sides of the tube, and thereby gaining access to the food. One raccoon figured out how to spin the floating ball to bring up marshmallow clinging to it.

So some of the raccoons solved the test, but not in the way the researchers intended. They demonstrated creative problem solving.

Other researchers are interested in how raccoons are adapting to human civilization. Most people in rural or suburban areas will have experience with raccoons. Raccoons also live in cities, but you may be less likely to see them.  They have learned that humans are a great source of food, if you can figure out how to break into their containers. Raccoons are also fairly dexterous, and can break into most things if there is food to be had.

Researchers have compared urban and rural raccoons, and found that urban raccoons have better trash-can opening skills. When confronted with unfamiliar containers, they are more confident and successful in figuring out how to get passed any obstacles. When tracked with GPS city raccoons can be seen avoiding high-traffic streets, and taking safer paths to their destination.

Two questions remain – is the increased intelligence of city raccoons only a result of learning, or is there some evolution going on. Raccoon populations have increased significantly in the passed 80 years, and they are increasingly moving into human-occupied areas, including cities. This suggests that they are adapting to human civilization.

This phenomenon may be similar to what is believed to have happened with dogs. They started living on the edge of human populations, taking advantage of the scraps humans leave behind. Those better able to interact with the humans had a survival advantage. In this way dogs may have already been partly domesticated before humans started breeding them.

So, are raccoons adapting to humans in the same way? Are they becoming not only more clever, but domesticated? If so, how long will this process take? Further, will raccoons split into two species, the wild raccoon and the domesticated raccoon, similar to wolves and dogs?

It seems likely that raccoons will respond to the massively changing environment represented by human civilization. They already seem to be flourishing and adapting. The question is, what niche will they find? They will not necessarily take the same path as dogs or cats. Perhaps they will just become better thieves, increasing not only their cleverness but their stealth.

We may have a clue to the future of raccoon in modern day experience with raccoons as exotic pets. Because they can be adorable, some people may think it would be cool to have a raccoon pet, but veterinarians warn that they make terrible pets.

First, they need constant supervision. They are very good at destroying things, and if you ever left them alone in your house they would cause significant damage. Caging them is not an option as it is cruel to cage a wild animal and that will just stress them out. Raccoons respond to stress by biting. They also cannot be house-trained, and so will relieve themselves anywhere. Essentially, they would be nightmare pets.

But what if they were truly domesticated? Are these inconvenient behaviors part of being wild, or are they just core to being a raccoon? Is getting into trouble and destroying things part of the raccoon personality that would not be solved simply by domesticating them?

It is interesting to think about the future of raccoons. They are clearly one species doing well in the increasingly urbanized world. They are smart and dexterous, do not really fear humans, and are usually not dangerous (unless they have rabies or you provoke them into biting you). How far with their adaptation go? Will we see a future of super smart or fully domesticated raccoons? It’s not unlikely.

Glyphosate Not Associated with Cancer

neurologicablog Feed - Fri, 11/10/2017 - 4:54am

In March of 2015 the International Agency for Research on Cancer (IARC), part of the World Health Organization (WHO) published their assessment on glyphosate, Monsanto’s popular weedkiller, classifying it as 2a – a probable carcinogen. This was like red meat to the anti-GMO crowd, and even sparked class action suits against Monsanto and may lead to banning use of the chemical in the EU.

There were significant problems with the IARC report, however. First – it is at odds with every other expert review of the scientific literature on glyphosate. I review the evidence here, citing many expert panel reviews, all conclude that the evidence does not support a link between glyphosate and risk of cancer. The IARC conclusion is a clear outlier, which reasonably prompts questions as to why their designation stands out.

We also need to put the IARC classification of 2a – probable carcinogen, into context. This is the same classification that the IARC gave to drinking hot beverages or eating red meat. Overall they tend to err on the side of caution when making their classification.

But there were problems that go beyond where the IARC sets their threshold for “probable.” Two main criticisms have emerged. The first is the lack of transparency. Reuters has published a series of articles on the issue, outlining, for example, that when the EPA reviewed the safety of glyphosate they also published a 1300 + page document that outlines the entire deliberative process. The IARC produced no such document.

Further, Reuters was able to obtain copies of the draft report and shows that the final report differs in significant ways. They found 10 major changes or omissions from the draft to the final copy, every one in the direction of emphasizing the risks of glyphosate. It is not known who made these edits, and the IARC responded by essentially instructing their scientists not to discuss the confidential deliberative process.

Far more important, however, is the accusation that the lead IARC scientist knew of unpublished data (because he was involved in the research) that showed no correlation between glyphosate and cancer, but this data was not considered in the review. So the lead scientist excluded his own data from the final analysis.

That data has now been published. 

The study comes from the Agricultural Health Study. Here are the results:

Among 54 251 applicators, 44 932 (82.8%) used glyphosate, including 5779 incident cancer cases (79.3% of all cases). In unlagged analyses, glyphosate was not statistically significantly associated with cancer at any site. However, among applicators in the highest exposure quartile, there was an increased risk of acute myeloid leukemia (AML) compared with never users (RR = 2.44, 95% CI = 0.94 to 6.32, Ptrend = .11), though this association was not statistically significant. Results for AML were similar with a five-year (RRQuartile 4 = 2.32, 95% CI = 0.98 to 5.51, Ptrend = .07) and 20-year exposure lag (RRTertile 3 = 2.04, 95% CI = 1.05 to 3.97, Ptrend = .04).

This is the best and largest set of data to date, and it was negative. The possible association with AML requires further discussion, as I am confident it will be seized on by those with an anti-glyphosate agenda. First and most importantly, this association was not statistically significant. This means it is almost certainly noise in the data. Give the number of possible correlations being examined, non-significant possible correlations are almost inevitable.

There are two other reasons to think this association is noise – there was no difference between the 5 year and 20 year exposure lag. If this were a true cause and effect, we would expect the lag time to matter. Even more significant, however, is the fact that previous possible correlations were between glyphosate and non-Hodgkins lymphoma (NHL). That is the association that led to the IARC classification. There was no association with NHL is this data, just a non-significant association with AML. This is exactly what we expect to find with random noise – different correlations in different sets of data. Such correlations don’t mean anything until they are replicated in an independent set of data.

So the bottom line is that this large data set is essentially negative regarding any association between glyphosate and cancer. If the IARC had taken this data into consideration it may have (and it seems should have) changed their conclusions. They knew about this data, but chose to ignore it.

The issue of glyphosate is controversial because it has become a focal point for an ideologically struggle. For the anti-GMO movement it is the poster-child of corporate malfeasance. For corporations this is an example of activist government overreach.

I tend to think that both sides are correct, at least to an extent. We should not trust corporations, meaning that we should not just assume they will be good corporate citizens, never abuse their power, or that they will consider the public interest over their shareholders. There is overwhelming evidence that, generally speaking, this is not a good assumption. Corporations look after their own bottom line. That is why we need regulations, transparency, and oversight to protect consumer and public interests.

I also don’t think we can trust activist organizations, nor can we assume that government agencies will act without ideological bias. Again, history tells a very different story.

What we need, therefore, are professional disinterested reviewers. We need scientific experts to review objective evidence, and investigative journalists to make sure there is transparency. They don’t always do their job optimally either, but the whole system acts as a set of checks and balances.

The story of glyphosate and the IARC review is a microcosm of all this. We see multiple different interests, each with a different narrative interpretation of reality, fighting over what is, at the end of the day, a scientific question. What is the safety of glyphosate in the context of how it is used and compared to other alternatives? The best we can do is to have multiple independent experts review all the evidence and give us a transparent assessment. If a consensus emerges and that consensus includes the opinion that there is sufficient evidence to reach a conclusion, then that conclusion is probably the most reliable answer we can get.

In the case of glyphosate we actually have a large set of data with multiple independent reviews concluding it is relatively safe as used, and is superior to most other herbicides. The IARC review is an outlier, and the process used has come under significant criticism suggesting bias.

In any case, the recent published data from the AHS renders all previous reviews obsolete. This new data argues strongly against any link between glyphosate and cancer. In light of this, the IARC should update their classification, as their now obsolete classification is actively being used as a basis of lawsuits and regulations.

Evolution Caught in the Act

neurologicablog Feed - Thu, 11/09/2017 - 5:15am

The hypothesis that life on Earth as it is currently found is the result of biological evolution from a common ancestor over billions of years is supported by such a mountain of evidence that it can be treated as an established scientific fact. Further, it is now a fundamental organizing theory of biology.

This, of course, does not stop ideologically motivated denial. There are those who have been systematically misinformed about the evidence, and the nature of science itself. What they think they know about evolutionary theory they learned from secondary hostile sources. One of the common lies they are repeatedly told is that there are no transitional fossils.

This claim amazes me still, because the evidence is so easily accessible. Lists of transitional fossils are easy to find. One of my favorite examples is the evolution of birds, because the morphological transition from theropod dinosaurs to modern birds was so dramatic.

I also have to point out that this evidence represents a successful prediction of evolutionary theory. When Darwin first published his theory the fossil record was scant. Enough fossils had been discovered for scientists to see that life was dramatically changing over geological time, but the puzzle was mostly empty. There were not enough specimens to see connections between major groups. Evolutionary theory predicts that such connections would be found – and they were, and they continue to be.

The fossil record is such a slam-dunk win for evolutionary theory that deniers have no choice but to simply lie and falsely state that they don’t exist. They try to divert attention to the remaining gaps in the record, or the occasional fossil hoaxes. When you point out the many dramatic transitional fossils they perform the intellectual equivalent of sticking their fingers in their ears and saying, “La, la, la.”

The most dramatic transitional fossils relate to evolutionary changes resulting from a major change in lifestyle. When dinosaurs took to the wing, for example. Or whenever creatures adapt from the sea to land, or from the land back to the sea. Whales are a great example. We now have a compelling sequence of transitional whales, and can see the slow loss of legs over time, the movement of the nostril to the top of the head, the increase in size, and the development of flippers. Ambulocetus is about half way through this transition – a literal walking whale.

In addition to the well-known groups, there are many nicely documented transitions in less well-known groups – for example, the pleurosaurs. These are ancient reptiles that went back to the sea and evolved to an aquatic lifestyle. They are similar in this way to the plesiosaurs, ichthyosaurs and mosasaurs.  A recent specimen was discovered that is 155 million years ago, is remarkably well-preserved, and represents a clear transitional species. As Science reports:

The creature (which the scientists dubbed Vadasaurus, Latin for “wading lizard”) lived 155 million years ago and didn’t have the elongated trunk or relatively shorter limbs that later aquatic species of pleurosaurs did, the researchers report today in Royal Society Open Science. So, Vadasaurus would have been less streamlined overall than its aquatic kin, they suggest. But other features, such as the shape of its skull and the shape and placement of its nostrils, hint that some aspects of the creature were indeed becoming more adapted to an aquatic lifestyle.

So it was partly adapted to the sea, but not completely. Later specimens show more complete adaptation to the water. The specimen also had less ossification, meaning lighter bones, than its terrestrial ancestors. Lighter bones would be an aquatic adaptation – they would make floating easier and heavier bones would not be necessary for support in the water.

Aquatic adaptation is an excellent window into evolutionary change, because life in the water produces a suite of strong selective pressures. You can survive in the water, for example, with stumpy legs, but they are just getting in the way. They slow you down, so there is continuous selective pressure for smaller legs. Therefore we see in the fossil record progressively smaller hind limbs in groups adapting to the sea. Modern whales are left with just an internal bony vestige.

Another strategy evolution deniers use to sow doubt and confusion about the fossil evidence is to focus on tiny details and ignore the bigger picture. Here is a good example from the Orwellian named,  Evolution News. They report on two new transitional fossils, including another feathered dinosaur. The author does not acknowledge that such specimens fill in the morphological space of already known species, and therefore are transitional, providing further evidence for evolution. Rather, they argue, that because these specimens change the way we draw the lines of descent they are evidence against evolution.

That is a common tactic- misinterpret disagreement or uncertainty about the details as if it calls into question the bigger reality. Scientists are trying to piece together exactly what evolved from what when based upon an incomplete record. This is like trying to put jigsaw puzzle pieces in the right place when you only have 10% of the pieces. Every time you find a new piece there is the chance that it will change where you think the pieces go.

If evolution were not true, however, we would not be finding any pieces, or we would be finding pieces to other puzzles entirely. Once we started digging up fossils we could have found a complete absence of life prior to 10 thousand years ago. We could have found that species are stable throughout geological history. We could have found different species, but ones with not possible relationship to extant species.

That is not what we found. We found, as evolutionary theory regarding common descent predicts and requires, dramatically and sequentially changing multicellular species going back 550 million years. Further, fossil species largely fit into a compelling evolutionary pattern. We find creatures that are plausible ancestors to living creatures. We don’t find fossils that are impossible chimeras or totally out of sequence.

However, when you drill down to the details, the fossil record does not always provide enough evidence to make precise reconstructions. Scientists interpolate as best they can from existing evidence, but during this phase of discovery new evidence can significantly change how these maps are drawn. That does not call into question the fact of common descent itself. Pretending it does is intellectually dishonest, which is the hallmark of evolution deniers.

The fact remains, with each new transitional fossil discovered, there is another vindication for evolutionary theory.
