Doing some background reading on genomics topics such as: Cross-population predictive validity of genomic scores (polygenic scores). LD-decay. Causal variant tagging / distribution of causal variants / genetic architecture. Admixture mapping accuracy given LD decay. Implications of the above for research into genetic causes of group differences in polygenic traits. Implications of the above for…
Continue ReadingIn many ways, my science — and my colleagues’ science — generally involves collecting evidence for obvious hypotheses that are mainly denied by leftist-leaning people (more precisely, egalitarian). Here’s a brief review. Stereotypes about major demographic groups are quite accurate Jussim of course already showed this, but since it’s still frequently denied, seems that we…
Continue ReadingWrote a new re-analysis for another meta-analysis of exercise for depression. Found good evidence of publication bias again. Unclear what the effect size really is, but my posterior 95% range is something like -.05 to .50. http://rpubs.com/EmilOWK/Schuch2016_reanalysis
Continue ReadingIn evolutionary biology, there is a hypothesis about sex ratios: Trivers-Williard hypothesis. It has been noted that males have higher dispersion in their fertility than females have, a finding that is also true in humans (one, two, three). If resources are related to fertility — which they are in many species and used to be…
Continue ReadingI don’t have time to do this project right now. However, since I gathered a bunch of relevant resources that I don’t want to have to re-find, I will write them down somewhere — here. My blog is my extended memory. Music genres are another fuzzy concept, like races. Lots of genres (and classification systems…
Continue ReadingDisclaimer: I did not read Rushton’s seminal book on the topic. I was only first recently able to obtain a complete electronic copy (i.e. not abridged version). I did in fact only skim this literature. I don’t have time to work on this, but I’d like others to do so, hence I put the labor…

Genetic and Environmental Influences on Personality: A Study of Twins Reared Together Using the Self- and Peer Report NEO-FFI Scales. Journal of Personality, 65(3), 449–475. https://doi.org/10.1111/j.1467-6494.1997.tb00324.x Connelly, B. S., & Ones,…
Continue ReadingI read the following interesting paper: Braun, S. T., & Stuhler, J. (2016). The Transmission of Inequality Across Multiple Generations: Testing Recent Theories with Evidence from Germany. The Economic Journal, n/a-n/a. https://doi.org/10.1111/ecoj.12453 This paper shows that across multiple generations, the persistence of occupational and educational attainment in Germany is larger than estimates from two generations…
Continue ReadingI was skimming a Wikipedia article related to immigrant crime and came across an obscure Swedish language report from the 1990s: Ahlberg, J. (1996). Invandrares och invandrares barns brottslighet: En statistisk analys [Immigrants’ and immigrants’ children’s crime: a statistical analysis]. Brottsförebyggande rådet (BRÅ). (file available on OSF) This report is a goldmine. Briefly: Data from…

Retrieved from https://openpsych.net/paper/50 So the German paper is finally out. As far as I know, this is the most extensive analysis of immigrant crime in Germany. Still, it is a quite simple analysis in some ways….
