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)).

For new analyses or error checking previous work. Scientists are human and often refuse access to data for hostile outsiders, preventing them…

Many libertarians defend women’s voting rights (suffrage) by reference to general principles about equality of legal rights. The historical reason for this move, I think, is that libertarians and classical liberals was a political reaction to the extra legal rights of the nobility and royalty. Thus, their goal was to equalize such rights, and this…
Below I list all the studies I am aware of that use national IQs in studies of immigrants, usually as an estimate of their IQ levels in the host country. Most of these studies are authored by me and coauthors, but not the first two from 2010, which were seemingly independently conceived by two sets…
