Western, Educated, Industrialized, Rich, and Democratic, that is. One of the common complaints about evolutionary psychology is that it claims to be addressing evolved human universals, but when you look at the data sets, they are almost always drawn from the same tiny pool of outliers, Western undergraduate students enrolled in psychology programs, and excessively extrapolated to be representative of Homo sapiens — when we’re actually a very peculiar group. How peculiar? A paper by Henrich, Heine, and Norenzayan, “The Weirdest People in the World”, tries to measure that…and by nearly every standard they looked at, the wealthy inhabitants of democratic western societies are not exactly normal (that is, they’re far from average in ways both good and bad and value neutral). Who are the people studied in behavioral science research? A recent analysis of the top journals in six sub‐disciplines of Psychology from 2003‐2007 revealed that 68% of subjects came from the US, and a full 96% of subjects were from Western industrialized countries, specifically North America, Europe, Australia, and Israel (Arnett 2008). The make‐up of these samples appears to largely reflect the country of residence of the authors, as 73% of first authors were at American universities, and 99% were at universities in Western countries. This means that 96% of psychological samples come from countries with only 12% of the world’s population. Put another way, a randomly selected American is 300 times more likely to be a research participant in a study in one of these journals than is a randomly selected person from outside of the West. It’s even worse: “67% of the American samples (and 80% of the samples from other countries) were composed solely of undergraduates in psychology courses”. That wouldn’t be so bad if we were examining traits that were truly universal, or if we had a better understanding of exactly what...

It is a very good and measured response that highlights the flaws in bad evolutionary psychology. Evolutionary psychology, the study of human psychological adaptations, does not have a popular or scientific reputation for being rigorous, even though there are rigorous, thoughtful scientists in the field. The field is trying to take on an incredibly challenging task: understand what of human behavior is adaptive and why. We can better circumvent the conditions that lead to violence, war, and hatred if we know as much as we can about why we are the way we are. What motivates us, excites us, angers us, and how can evolutionary theory help us understand it all? Because of this, there are consequences to a bad evolutionary psychology interpretation of the world. The biggest problem, to my mind, is that so often the conclusions of the bad sort of evolutionary psychology match the stereotypes and cultural expectations we already hold about the world: more feminine women are more beautiful, more masculine men more handsome; appearance is important to men while wealth is important to women; women are prone to flighty changes in political and partner preference depending on the phase of their menstrual cycles. Rather than clue people in to problems with research design or interpretation, this alignment with stereotype further confirms the study. Variation gets erased: in bad evolutionary psychology, there are only straight people, and everyone wants the same things in life. Our brains are iPhones, each app designed for its own special adaptive purpose. I’ve still got plans to post more on this subject, but an unfortunate event has blocked me. I was going to make my next post on evolutionary psychology one that focused on some of the papers, and in particular, I wanted to discuss a good paper or two, so that I could start off on the right tone. And people sent me links and papers. Only problem: they were all awful. Every one. I couldn’t believe that even...

This is another addition to my αEP series about evolutionary psychology. Here’s the first, and unfortunately there are several more to come. By the way, people are wondering about the α in the title. Don’t you people do any immunology? α is standard shorthand for “anti”. I mentioned in the last one this annoying tendency of too many pro-evolution people to cite “complexity” as a factor that supports the assertion of selection for a trait. Strangely, the intelligent design creationists also yell “Complexity!” at the drop of a hat, only it’s to prove that evolution can’t work. They’re both wrong. I ran across a prime example of this recently in a post by John Wilkins (It’s pick-on-John-Wilkins day! Hooray!) Read more

This is another addition to my αEP series about evolutionary psychology. Here’s the first, and unfortunately there are several more to come. I have a real problem with evolutionary psychology, and it goes right to the root of the discipline: it’s built on a flawed foundation. It relies on a naïve and simplistic understanding of how evolution works (a basic misconception that reminds me of another now-dead discipline, which I’ll write about later) — it appeals to many people, though, because that misconception aligns nicely with the cartoon version of evolution in most people’s heads, and it also means that every time you criticize evolutionary psychology, you get a swarm of ignorant defenders who assume you’re attacking evolution itself. That misconception is adaptationism. Read more

This is one of a series of posts I’m working on over the next few days to criticize evolutionary psychology. More will be coming under the label αEP! Recently, Bob Costas, a sports announcer, spoke out about gun control. In reply, the right wing has been in a frenzy of denunciations — he should just shut up, he’s not qualified to speak, he can’t possibly have reasonable opinions about anything other than football (of course, these same angry commentators don’t express similar opinions about Ted Nugent). It’s called Shut Up and Sing Syndrome. Named after a Laura Ingraham book and a 2006 documentary about the harsh reaction to the Dixie Chicks’ anti-Bush comments, this syndrome condemns many Americans to believe that actors, musicians and athletes — really, anyone not deemed political “experts” — have no right to use their platform to address issues considered “political” in nature. In this case, conservatives are insisting that Costas is not merely wrong on the substance of his gun-related comments, but also that, according to the New York Times, “it was inappropriate to use the platform of an NFL telecast to make arguments concerning a hot-button issue like gun control.” The insinuation is that as a sportscaster, he has no standing to weigh in on a political issue. In other words, like critics of outspoken athletes who tell them to “shut up and play,” critics want Costas to simply “shut up and talk only about sports.” Sound familiar? It should. It’s a problem in more than just entertainment and politics — it’s also a problem in skepticism. What it really is is an authoritarian defense of orthodoxy that dismisses criticism unless it comes from the right kind of person — preferably one comfortably embedded deeply in the orthodox position. It’s a version of the Courtier’s Reply, only in this case it’s used to defend science, or a political position,...
