Some of the talks from ISIR 2016 in Saint Petersburg are now online. In particular, I enjoyed Detterman’s talk, but of course I think he is too pessimistic about reproductive genetics. All the talks were recorded, but only the long ones with the most famous people are published so far, so you will have to […]

Following the publication of another gender pay gap article, I wondered: What kinds of gender gaps do people think are important to talk about? Googling stuff is a crude measure of just this. The results: “gender wage gap” 448,000 “gender pay gap” 462,000 “gender income gap”, 14,000 “gender wealth gap” 4,340 vs. “gender lifespan gap” […]

rpubs.com/EmilOWK/208757 Analysis of the data collected so far, presented side by side with R code. It will be expanded into a proper paper and submitted to OQSPS soonish. Soonish here meaning when Noah gets around to do it! Due to the surprising results, we should probably do a follow-up replication using new subjects. These results […]

One of the things that bother me with the current research on gender differences in personality is the reference group approach problem. Researchers ask questions that require participants to make comparisons between themselves and some implicit group. Gerhard Meisenberg pointed out the problem with this approach for cross-cultural research: A potentially remediable source of low […]

I stumbled upon another physicist venturing into someone else’s field and getting things right. I quote from Pinker’s Better Angels: In the early 1950s, two eminent British scholars reflected on the history of war and ventured predictions on what the world should expect in the years to come. One of them was Arnold Toynbee (1889–1975), […]

In a not so well written paper (that we should update to be better presented), John Fuerst and I previously used two hypotheses using the National Longitudinal Survey of Freshman dataset: Spatial transferability: when people move, they tend to keep their psychological traits and culture. Generational transferability: when people have children, their children tend to […]

I was recently asked to suggest introductory reviewing materials for bright laymen (see also my previous post). I ended up giving the following recommendations: – Intelligence: A very short introduction (2001, by Deary, very mainstream researcher). 132 pages. Libgen – Intelligence: All that matters. 2015. Ritchie (young, mainstream researcher). 160 pages. Libgen Bit more technical, […]

For some research designs, one pays the participants by the amount of time they spend on the task (like regular work). For other designs where one does not, usually participants are able to drop out if one annoys them too much. In both cases it is important to use brief measures. Still, when one uses […]

I learned about this topic many years ago reading Scott Lilienfeld‘s 50 Myths of popular psychology. In it, they write: In his blockbuster bestselling book Blink: The Power of Thinking Without Thinking, journalist Malcolm Gladwell (2005) argued that experts reach decisions by focusing on the most relevant information and making accurate snap judgments. They can […]
