First we had 3 laws, then a 4th. I’ll propose a 5th: All human behavioral traits are heritable. The effect of being raised in the same family is smaller than the effect of genes. A substantial portion of the variation in complex human behavioral traits is not accounted for by the effects of genes or […]

Generally my stance is that people should date/mate who they want. Furthermore, I don’t personally care much about this question or the future survival of statistical clusters (races). Asserting that there are problems with cross-racial mating smacks of 19th century race thinking. However, it would not the first time people in the past got things […]

Being annoyed by some of the usual qualitative drivel masquerading as science (see almost any tweet by @RealPeerReview), I was moved to make a nice background/poster. en.wikiquote.org/wiki/William_Thomson A slide from some anthropologist said of Galton that he “Worshipped at the alter of quantification”. That’s a nice way to put it!

Note: I found two persons to do this so far. 1. Skills required Ability to copy paste from this Wikipedia page into a spreadsheet. Ability to find the elementary information for a study. 2. Job description A meta-analysis relies on a dataset of information about other studies. One of us collected a large number of […]

Because I hate seeing solid contributions go unnoticed. Few remember Barbara Stoddard Burks for the early pioneer of behavioral genetics she was. She doesn’t even have a Wikipedia article. I will fix that shortly. In their article on the sociologist’s fallacy in interpretation of familial data, Rowe and Rodgers (1997) mention Burks thus: The issues […]

I don’t have time to provide extensive citations for this post, so some things are cited from memory. You should be able to locate the relevant literature, but otherwise just ask. Haier, R. J. (2016). The Neuroscience of Intelligence (1 edition). New York, NY: Cambridge University Press. Because I’m writing a neuroscience-related paper or two, […]

This is commentary on: Ellis, L., Hoskin, A. W., Dutton, E., & Nyborg, H. The Future of Secularism: a Biologically Informed Theory Supplemented with Cross-Cultural Evidence. Evolutionary Psychological Science, 1-19. For over a century, social scientists have predicted declines in religious beliefs and their replacement with more scientific/naturalistic outlooks, a prediction known as the secularization […]

This is a break from the usual technical sciency stuff! I talked with John Fuerst about how weird it is that people all over the Western world were watching the same American produced cartoons as a child. A kind of pan-Western world environmental effect, if there are any long term effects of watching these, aside […]

h/t to SSC for leading to me discovering the most curious thing. So it turns out there’s a camgirl with an interesting blog featuring things like evidence-based camgirling (why not?) and a subjective experience based model of LSD tripping (based on doing LSD for every week for 10 months?!). Looking over her Twitter reveals that […]

Brian Boutwell et al has a new preprint out: The Experience of Discrimination in Contemporary America: Results from a Nationally Representative Sample of Adults A large body of social science research is devoted to understanding the causes and correlates of discrimination. However, less effort has been aimed at providing a general prevalence estimate of discrimination […]
