Is family-linked terrorism a cultural and genetic phenomenon?

Posted 03 Dec 2015 / 0

National Public Radio “In Worst Attacks, Terrorists Often Have Fraternal Bonds” This is an interesting — albeit brief — piece on a recent “pattern” that has emerged in terror attacks: teams of attackers are often composed of blood relatives. As a good scientist I have to point out that there’s a danger here of over-generalizing Read More

Jeremy Yoder on contemporary selection for increased human height

Posted 23 Nov 2015 / 0

Social Evolution Forum “Natural Selection on Human Height Doesn’t Measure Up To Much” I agree overall with Yoder’s analysis, although it seems that he misreads the study a bit: by my reading, women’s height also had an effect on the survival of offspring, although the effect was nearly half that of men. But Yoder’s larger Read More

Religious children are less altruistic… or maybe not…

Posted 16 Nov 2015 / 0

Image courtesy of Wikimedia Commons A recent study published in Current Biology claims to have demonstrated that children raised in religious households are less altruistic and more vindictive than their peers raised in non-religious households. Using two different tests — a Dictator Game conducted with stickers and a task that measured reactions to watching interpersonal Read More

Fascinating and clever study of how personal contact norms vary by relationship

Posted 10 Nov 2015 / 0

Image from PNAS Proceedings of the National Academy of Sciences “Topography of social touching depends on emotional bonds between humans” (Suvilehto et al. 2015) This is a really clever study in that it aggregates a lot of data that is collected rather efficiently from a lot of participants. This makes the results robust for this Read More

Jonathan Haidt on the business advantage of being ethical

Posted 10 Nov 2015 / 0

This is a fascinating talk by Jonathan Haidt, a psychologist situated within one of the most prestigious business schools in the world whose research focuses on morality and emotion. I can’t help but be impressed when someone addressing business concerns leads with biology, and Haidt does a good job of summarizing the “disruptive cooperation” (read: competitively-superior Read More

That beard and deep voice may be to put him in his place, not attract her

Posted 09 Nov 2015 / 0

There have been a lot of evolutionary psychology experiments that have tried to define both female and male attractiveness to the opposite sex, an indirect way to get at the nature of sexual selection in humans. A new study published in Behavioral Ecology reminds us that sexual selection is not the only process that has Read More

What’s the evolved function of curiosity?

Image courtesy of Jeffrey Pang via Wikimedia Commons Neuron “The Psychology and Neuroscience of Curiosity” (Kidd & Hayden 2015) This is a fantastic review of what is known about curiosity and what needs to be learned about curiosity in the near future. I was glad to see the “four questions” approach to curiosity here. Tinbergen’s questions Read More

David Sloan Wilson on how Jeff Bezos don’t know squat about chickens (or evolution!)

Posted 16 Oct 2015 / 1

Evonomics “Jeff Bezos got Darwinism all Wrong!” This is an interesting analysis of the Bezos way of doing business, which represents an oft-lauded bastardization of Darwinian theory. What I like about Wilson’s brief analysis is that he focuses back on the unit of selection that matters for a business: the corporation. Unless you naively believe Read More
