Evolutionary Psychology

The title of this post is, of course, a parody of the sociobiological, or in modern parlance, the "evolutionary psychology" argument linking behaviors that evolved in our species during the long slog known as The Pleistocene with today's behavior in the modern predator-free food-rich world. And, it is a very sound argument. If, by "sound" you mean "sounds good unless you listen really hard." I list this argument among the falsehoods that I write about, but really, this is a category of argument with numerous little sub-arguments, and one about which I could write as many blog posts as I…
If you read only one book this holiday season, make it all of the following twenty or so! But seriously ... I'd like to do something today that I've been meaning to do, quite literally, for years. I want to run down a selection of readings that would provide any inquisitive person with a solid grounding in Behavioral Biological theory. At the very outset you need to know that this is not about Evolutionary Psychology. Evolutionary Psychology is something different. I'll explain some other time what the differences are. For now, we are only speaking of fairly traditional Darwinian…
Two posts for your consideration. On the Less Wrong weblog, Babies and Bunnies: A Caution About Evo-Psych. I am not one to make blanket dismissals of "evolutionary psychology." But, there are structural problems with the strong incentives toward generating hypotheses at the equipoise of novelty and intuitive plausibility. In other words, much of the evo-psych which penetrates the broader public mindspace is driven by demand-side forces. Over at EconLog Bryan Caplan has a post, Born Gay, where the newly famous Ryan Sorba is shown to be pretty close to a total behavior genetics denialist. Until…
Since my last post was rather pessimistic, I thought I'd point to something a little more cheerful, Social Scientists Build Case for 'Survival of the Kindest': Researchers at the University of California, Berkeley, are challenging long-held beliefs that human beings are wired to be selfish. In a wide range of studies, social scientists are amassing a growing body of evidence to show we are evolving to become more compassionate and collaborative in our quest to survive and thrive. In contrast to "every man for himself" interpretations of Charles Darwin's theory of evolution by natural…
At Cognition & Culture, a review of Sarah Blaffer Hrdry's new book, Mothers and Others: The Evolutionary Origins of Mutual Understanding. I really liked her previous work, Mother Nature, so I'm definitely going to check this out. Sarah Blaffer Hrdy was a prominent source in Ullica Segerstrale's Defenders of the Truth: The Sociobiology Debate.
Update: The author of the paper clears up confusions. Update: Here's the paper. End Update The British media is abuzz with another paper from Satoshi Kanazawa, the evolutionary psychologist who has great marketing savvy. I can't find the study online anyway, so here is the Times Online: In a study released last week, Markus Jokela, a researcher at the University of Helsinki, found beautiful women had up to 16% more children than their plainer counterparts. He used data gathered in America, in which 1,244 women and 997 men were followed through four decades of life. Their attractiveness was…
On this week's Science Saturday John Horgan interviews Richard Wrangham. The second half of the conversation focuses on Wrangham's new book, Catching Fire: How Cooking Made Us Human. I've heard pieces of the arguments mooted in the back & forth before, but it looks like in this book they're all brought together. Humans are a large animal with a very small gut, so we need to maximize the bang-for-the buck when it comes to what we eat. Unlike gorillas and to a lesser extent chimpanzees we just aren't able to process enough low quality vegetable matter to keep ourselves going. Part of this…
Evil Genes: Why Rome Fell, Hitler Rose, Enron Failed, and My Sister Stole My Mother's BoyfriendWhen I first received this book to review, I thought "Oh, great, another one of these pop evolutionary psychology books by some academic with a large mortgage payment" (or words to that effect). But then I read it and my attitude got better. The theme of this book is as the title says, evil ... at several scales, and understanding evil from a neuro-psychological perspective. Here, the genes themselves are actually relatively unimportant except as part of the necessary steps to build a human…
The World's Fair is pleased to offer the following discussion about The Caveman Mystique: Pop-Darwinism and the Debates Over Sex, Violence, and Science (Routledge, 2007), with its author Martha McCaughey. McCaughey is a Professor of Sociology and the Director of Women's Studies at Appalachian State University. Professor McCaughey's work fits at the intersections of gender, sexuality, science, technology, social movements, and the media. I first met her during her tenure at Virginia Tech, where she distinguished herself as a leading feminist scholar in science studies, an atypically…
David Brooks has a new column grandly titled The End of Philosophy. Heather Mac Donald at Secular Right chides him for his criticism of the New Atheists, while John Derbyshire offers guarded praise. It seems to me that the jab at the New Atheists was something of a throwaway line and I lean more toward John's position. I give Brooks credit for attempting to inject insights from the new cognitive sciences into contemporary political commentary. Politics is a phenomenon which manifests on a grand scale, but its ultimate roots are at least in part in individual human psychology. The empirical…
Dawkins gave a talk that could be criticized as not particularly new, in that his main idea is that human brains are too powerful and adaptable to continue to function primarily within an adaptive program serving as a proper adaptive organ. Instead, human brains think up all sorts of other, rather non-Darwinian things to do. This idea has been explored and talked about in many ways by many people. Kurt Vonegut Jr.'s character in Galapagos repeatedly, in a state of lament, quips "Thanks, Big Brain..." as evidence accumulates that our inevitable march towards extinction is primarily a…
Would you gamble on a safe bet for the promise of something more? Would you risk losing everything for the possibility of greater rewards? In psychological experiments, humans tend to play it safe when we stand to gain something - we're more likely to choose a certain reward over a larger but riskier one. Now, we're starting to understand how our two closest relatives deal with risk - bonobos, like us, tend to be risk-averse while chimpanzees usually play the odds. Sarah Heilbronner from Harvard University studied the attitudes of five chimps and five bonobos to risky decisions. All the…
