Kirkegaard, E. O. W. (2020). Human Biodiversity for Beginners: A Review of Charles Murray’s Human Diversity. Mankind Quarterly, 60(3). Journal (gated) Human Diversity is Charles Murray’s latest book. This review evaluates the claims made in the book and places both the author’s theses and their criticisms in their historical context. It concludes that this book…

A Report of the Center on Education Policy. Bainbridge, W. L., & Lasley, T. J. (2002). Demographics, diversity, and K-12 accountability: The challenge of closing the…
Kirkegaard, E. O. W. & de Kuijper, M. (2020). Public Preferences and Reality: Crime Rates among 70 Immigrant Groups in the Netherlands. Mankind Quarterly, 60(3) journal link (gated) We estimated crime rates among 70 origin-based immigrant groups in the Netherlands for the years 2005-2018. Results indicated that crime rates have overall been falling for each…
In Making sense of Heritability, Sesardić wrote: On the less obvious side, a nasty campaign against H could have the unintended effect of strengthening H [hereditarianism] epistemically, and making the criticism of H look less convincing. Simply, if you happen to believe that H is true and if you also know that opponents of H…
Now that the video is up, here’s some other studies I came across. Falkenberg, L. (1990). Improving the accuracy of stereotypes within the workplace. Journal of Management, 16(1), 107-118. Has a pretty straightforward summary of stereotypes and stereotyping: Organizations experience high levels of inefficiency when decisions are based on inaccurate stereotypes. As humans are dependent…
Some time ago, I made a plot of this that Steve Hsu ended up posting. However, here’s a newer one. The public datafile is here. Latest published report is here, which reports data for 2014. They publish a paper every year, or so, which report on ~5 year old data. I see no report for…
Published a new video summarizing the stereotype accuracy and bias evidence. Well, some of it! Also then discuss various implications for taking accuracy seriously in a Bayesian framework. 75 minutes long!
Counting significant hits was always a dumb way to measure progress in genomic prediction of a trait. Breeders using animals and plants never bothered with this approach and they used ridge regression for best predictive power (a “two cultures” problem no doubt). Researchers in human genetics are starting to catch up, implementing clever Enet approach…
Eysenck, H. J. (1995). Genius: The natural history of creativity (Vol. 12). Cambridge University Press. The book is on LibGen I continue my Eysenck readings with his popular genius book (prior review The Psychology of Politics (1954)). Having previously read some of Simonton’s work, Eysenck sure is a very different beast! The writing style follows…
Open data is a fundamental part of getting science to work well. Primary reasons for this: Redundancy is data archiving. Most data are lost because no backups exist! Easy access to 3rd parties. For new analyses or error checking previous work. Scientists are human and often refuse access to data for hostile outsiders, preventing them…
