Brian Boutwell et al has a new preprint out: The Experience of Discrimination in Contemporary America: Results from a Nationally Representative Sample of Adults A large body of social science research is devoted to understanding the causes and correlates of discrimination. However, less effort has been aimed at providing a general prevalence estimate of discrimination […]

Rnotebook: rpubs.com/EmilOWK/immigrant_IQ_Danish_draft Because I was discussing this dataset with a friend, I decided to reexamine it. Examining this dataset was my first reviewed paper (Kirkegaard 2013). It was manually done in Excel with no statistical guidance. So I had to work out everything myself based on googling around for formulas. My first write-up was not […]

In 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 […]

I 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. 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 […]

I 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 […]

Kirkegaard, E. O. W., & Becker, D. (2017). Immigrant crime in Germany 2012-2015. Open Quantitative Sociology & Political Science. Retrieved from 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. […]

Woodley convinced me that these are of actual interest. As some of you may recall, I compiled a large county level (n≈3000) dataset some time ago, but didn’t use it for anything. I just thought it would be a cool dataset, but that results were not too interesting. Well, since someone did think these were […]

I have only been able to find one fairly detailed dataset of immigrant performance in the Netherlands (covered in this study). It found the usual things, but with much uncertainty because the numbers were old (fewer immigrants back then → sampling error), covered a single year only (sampling error) and there was only one kind […]

Gwern has an old note on the US’ offer to buy Greenland from Denmark after WW2. Aside from the usual nationalist feelings about land, the Greenland population is ~25% genetically Scandinavian, presumably mostly Danish. This number is from genomic studies, the sociological counts differ somewhat because they include the mixed persons in the Inuit group […]
