Swatting through Luke Barnes’ Review of “Why Evolution is True”

Luke Barnes is a postdoctoral researcher in the field of astronomy at the University of Sydney. He is probably a very competent astronomer. However, he seems to have some issues with modern evolutionary biology but dislikes being labeled a creationist. Despite his statements being very carefully engineered, he repeats many classic tactics and tropes of creationists.

Barnes wrote a three-part book review of Jerry Coyne’s book “Why Evolution is True” a while back that I will take pleasure in disentangling. I’m not someone who would defend Coyne no matter what, as I have strongly criticized his anti-psychiatry stance a couple of times before on this blog.

Barnes alludes to the stereotype that physicists tend to march into a field not closely related to physics and make sweeping proclamations about conclusions and problems in that field, especially if this field is perceived as being less stringent than physics. There are a few notable examples of where this has not turned out that good such as Freeman Dyson and climate change, Roger Penrose and consciousness as well as Linus Pauling (quantum chemist) and high doses of Vitamin C.

Generally speaking, the three parts roughly corresponds to criticizing the positive case for evolution, opposing the positive and negative case against intelligent design creationism and the supposedly negative effects of evolutionary biology on society. However, I will do my review of the review in one single post because I can focus on the core claims and misunderstandings.

Confronting Jerry Coyne on His Stance on Medical Psychiatry

Another couple of months has passed since Jerry Coyne, Professor of Ecology and Evolution at the University of Chicago, made his latest claims about psychiatry and psychiatric drugs. I have dissected many of his unreasonable claims about psychiatry on two occasions previously, in Why Jerry Coyne is Wrong about Medical Psychiatry and in the follow-up post Why Jerry Coyne is Still Wrong about Antidepressants. Since I feared that Prof. Coyne had started to slide down that dangerous path into denialism and pseudoskepticism, I decided to send him an email with a few critical questions against his stance to see what he thinks about them. Could it be that he has changed his mind, or has he become frozen in his views?

The email is too long to cite in its entirely (used a lot of references and such, which can be found in the two posts linked above), so I will just summarize my 6 questions. I identified additional problems besides these six, but I feel that these are the main questions I would like to see what Prof. Coyne thinks about at this time.

1. Why does Prof. Coyne describe the mainstream explanatory model for depression as “chemical imbalance”, when most descriptions in elementary level psychology textbooks emphasize a large number of interacting biological, psychological and environmental factors that are each important in their own
right?

2. Why does Prof. Coyne think that the fact that the genetics of mental illness is rife with uncertainties undermine the notion that many mental illnesses have genetic predispositions when studies on identical twins and adoption studies show that the heritability is often moderate? Surely, there is a different between knowing that a genetic predisposition exists and knowing the exact mechanism on a molecular level? To take an analogy: even though we may not have all the details of how common descent happened (is this taxon more related to that taxon than this other taxon?), we can be pretty sure of common descent.

Why Jerry Coyne is Still Wrong about Antidepressants

A few months ago, Jerry Coyne, Professor in the Department of Ecology and Evolution at the University of Chicago and an staunch supporter of evolution against creationists, made a series of remarkably flawed claims about medical psychiatry in general and antidepressants in particular. He did this after reading a couple of book reviews on a few controversial books on psychiatry and asserted that medical psychiatry was a scam. Needless to say, I confronted his claims in Why Jerry Coyne is Wrong about Medical Psychiatry and shown that Prof. Coyne made several glaring errors: he incorrectly characterized the mainstream view on the causes of depression, he claimed that the effectiveness of a drug was not evidence for the underlying model (thus implicitly agreeing with HIV/AIDS denialists that the effectiveness of antiretroviral treatment is not evidence that HIV causes AIDS), he did not understand the difference between genetic mapping and estimations of heritability, he advocated Big Pharma conspiracy theories, incorrectly claimed (based on Kirsch flawed studies) that antidepressants are no better than placebo and contradicted himself by claiming that mental disorders were not caused by chemical factors in the brain while at the same time claiming that antidepressants cause psychopathology without any evidence.

After this, I stopped regularly visiting his blog, so it is only now that I noticed that he wrote a follow-up article called Peter Kramer defends antidepressants. In it, Prof. Coyne repeats many of the same flawed arguments as before and it reads like an advertisement of Kirsch book on antidepressants. It is now clearer than ever that Prof. Coyne has gone of the deep end with regards to this topic. It is clear that his pseudoskepticism is deepening and that is why I have decided to write another criticism. There will necessarily be some repeats of content that I discussed in previous entries, but will try to keep it to a minimum.

Let’s get started, shall we? Read more of this post
