This year (2018) Robert Sternberg is slated to give a distinguished contributor interview at the ISIR meeting to be held in Edinburgh. There’s already tons of material on his behavior: Extreme self-citations: replicationindex.wordpress.com/2018/04/22/robert-sternbergs-rise-to-fame/ Extreme text recycling (self-plagiarism): steamtraen.blogspot.fr/2018/04/some-instances-of-apparent-duplicate.html Editorial role abuse: www.insidehighered.com/news/2018/04/30/prominent-psychologist-resigns-journal-editor-over-allegations-over-self-citation and more However, here I want to point out an additional angle.

Rindermann, H. (2018). Cognitive capitalism: human capital and the wellbeing of nations. Cambridge, United Kingdom ; New York, NY: University Printing House. Heiner was kind enough to send me a reviewer’s (paper) copy. Unfortunately, I lack the time to write up a formal book review, and so this blogpost will have to do. James Thompson already […]

Doing a lot of background reading on animal ecology, I found this review paper: Lefebvre, L. (2013). Brains, innovations, tools and cultural transmission in birds, non-human primates, and fossil hominins. Frontiers in human neuroscience, 7, 245. Recent work on birds and non-human primates has shown that taxonomic differences in field measures of innovation, tool use […]

Miron Zuckerman is updating his meta-analysis of the religion and intelligence relationship, and asked me to compute some extra analyses of the OKCupid dataset. Results: rpubs.com/EmilOWK/intell_religion_OKCupid Main findings Cognitive ability is independent cause of the usual demographics. Distribution of cognitive ability by religious stance x seriousness. Error bars = 95% confidence intervals. Gays more religious […]

Antonio Regalado is providing us with a recent series of the arguably best informed (compared to Guardian, Nature news etc.) popular science articles on genomics and its relevance to modern eugenics (embryo selection or genetic engineering) as well as the group differences causation question. www.technologyreview.com/s/609204/eugenics-20-were-at-the-dawn-of-choosing-embryos-by-health-height-and-more/ www.technologyreview.com/s/610251/forecasts-of-genetic-fate-just-got-a-lot-more-accurate/ www.technologyreview.com/s/610339/dna-tests-for-iq-are-coming-but-it-might-not-be-smart-to-take-one/ As background for some of these, I had […]

It has been noted that East Asians are positive outliers for the latitude ~ IQ pattern, they’re too far south for their high IQs. Some possible reasons for this are: The peoples evolved further north and migrated south in recent times, and their intelligence level is related to their recent origin, not current location, just […]

Most environmentalists have by now given up denying the existence of racial gaps in head size, but they only retreated a few yards: Nisbett, R. E., Aronson, J., Blair, C., Dickens, W., Flynn, J., Halpern, D. F., & Turkheimer, E. (2012). Intelligence: new findings and theoretical developments. American psychologist, 67(2), 130. Brain size and IQ. […]

There’s an interesting slide in Rindermann’s survey: Rindermann, H. (2013). 2013 survey of expert opinion on intelligence. International Society for Intelligence Research, ISIR 2013 List of surveys here James Thompson’s previous coverage I’ve edited it to be in a single image (from 3). Do we have an estimate of relative media left-wingness for these? Some […]

There’s an interesting study making the rounds on Twitter: Great new study: In 2002, 1200 Nepalese pregnant women were randomly assigned to receive micronutrient supplements or not. Experimental children had heavier birthweights. Now, at age 12, there was no difference in Intelligence. @Shine_Daizy @marcelleprost t.co/ZyCtbJGEMs pic.twitter.com/V1iPbCxiES — John Protzko (@JProtzko) March 8, 2018 Dulal, S., […]

Someone sent me some questions on this study: Fagan, J. F., & Holland, C. R. (2007). Racial equality in intelligence: Predictions from a theory of intelligence as processing. Intelligence, 35(4), 319-334. African-Americans and Whites were asked to solve problems typical of those administered on standard tests of intelligence. Half of the problems were solvable on […]
