Higher education teaching loads are about economics, not valuing teaching

Posted 23 Nov 2015 / 0

The Chronicle of Higher Education “Why We Should Teach Less, Not More” This is a great opinion piece that effectively captures my perspective on this issue. High-quality higher education requires really labor-intensive curriculum development and maintenance. In order for a professor to provide a course that is comprehensive and up-to-date, she must spend countless hours 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

Maybe infants don’t really care who helps and who hinders after all…

Posted 16 Nov 2015 / 0

PLoS ONE “Probing the Strength of Infants’ Preference for Helpers over Hinderers: Two Replication Attempts of Hamlin and Wynn (2011)” Great example of how studies need to be replicated! I am wondering if funding agencies should reserve particular lines for replication studies. Does this kind of funding opportunity exist?

The problem with same sex attraction “for the good of the species”

Posted 16 Nov 2015 / 0

arXiv “Toy model for the adaptive origins of the sexual orientation continuum” This is an interesting idea that definitely bears further exploration, but by my reading of the math, the tradeoff here (what’s good for the species in having trait diversity versus what’s good for an individual in achieving reproductive success) is expressed purely in 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

Review of William B. Provine’s “The ‘Random Genetic Drift’ Fallacy”

Posted 05 Nov 2015 / 5

Just about a year ago, I got an unusual email. It was from William Ball Provine, a well-known historian of science most famous for his work on the modern evolutionary synthesis. Provine was especially well-known to me as the Ph.D. advisor to Greg Graffin of the punk band Bad Religion; although this is a story Read More

Did the population bombers drive China into cultural crisis?

Posted 05 Nov 2015 / 0

Image courtesy of Wikimedia Commons The Los Angeles Times “China drops its ‘one-child’ policy, now let’s ban the ‘population bomb’” Great op-ed that makes it really clear that impact is a function of not just the number of people on the earth but also the resources those people consume (affluence) and technologies used to produce Read More
