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 studies, but wrote them down on Wikipedia. Now, we want […]

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 […]

www.gwern.net/Embryo%20selection#counteracting-dysgenics Gwern has a very long and detailed post/page on embryo selection and related matters. You should definitely read it. He has just added a new section on counteracting dysgenics — the genetic evolution of undesirable traits — and asked for my comments/thoughts. The background for the discussion are the recent genomic findings supporting dysgenic […]

Gelman proposed the time reversal heuristic when evaluating discussions about failed replications. One helpful (I think) way to think about this episode is to turn things around. Suppose the Ranehill et al. experiment, with its null finding, had come first. A large study finding no effect. And then Cuddy et al. had run a replication […]

Rnotebook: rpubs.com/EmilOWK/immigrant_IQ_Danish_draft Because I was discussing this dataset with a friend, I decided to reexamine it. Examining this dataset was my first reviewed paper (Kirkegaard 2013). It was manually done in Excel with no statistical guidance. So I had to work out everything myself based on googling around for formulas. My first write-up was not […]
