Speaking of philosophy of science, one of the things about new paradigms is that they are supposed to solve anomalies of older paradigms. A while ago, Dalliard (2014) mentioned (in a footnote!) one of these, namely the attitude-achievement paradox. There’s quite a number of studies on it: The brief version is that black, Hispanic etc. […]

May be another case of a zombie idea: one that keeps being refuted only to come back under another term, and then await refutation for 10-20 years. It is also fairly obvious: systematic approaches to more or less everything work better than ad hoc, haphazard ones. There’s no reason to expect this also not to […]

All the talks were recorded, but only the long ones with the most famous people are published so far, so you will have to […]

A reader asked me to comment on the predictions/musings by Marty Nemko at his blog. I had never heard of him before, but he’s some kind of coach, radio host and columnist popular in the Bay Area. The decline in good jobs. My optimistic side predicts that improved education and gene editing to improve intelligence […]

It seems that no one has integrated this literature yet. I will take a quick stab at it here. It could be expanded into a proper paper later in case someone wants to and have time to do that. Stereotypes Lee Jussim (also blog) has done a tremendous job at reviewing the stereotype literature in […]

@JamesPsychol Those results don't look real to me. Betas are never exactly identical across models. — Emil OW Kirkegaard (@KirkegaardEmil) September 8, 2015 @JamesPsychol @KirkegaardEmil FSIQ is uncorrelated with the residualized factor index scores, so its beta doesn't change across models. — Timofey Pnin (@pnin1957) September 8, 2015 Let’s test that. Since we don’t have […]
