As others have pointed out many times (recently Richwine 2019), one cannot just use identical thresholds of educational attainment to select for identical levels of human capital (broadly conceptualized) among sending immigrant countries. Example of this was that Heiner Rindermann mentioned in an interview (in German) that: Selbst in einer Elitegruppe, Ingenieurstudenten aus den Golfstaaten,…

Retrieved from mankindquarterly.org/archive/issue/59-4/5 It is well established that general intelligence varies in the population and is causal for variation in later life outcomes, in particular for social status and education. We linked IQ-test scores from the Danish draft…
Continue ReadingThanks to Chet Robie for sending me his study. There’s been quite a bit of research on immigrant IQs. From within our network, Heiner Rindermann and James Thompson published a long analysis of scholastic achievement data: Rindermann, H., & Thompson, J. (2016). The cognitive competences of immigrant and native students across the world: An analysis…
Continue ReadingQuoting from Arthur Jensen’s book Educability and group differences (1973). He was being criticized for postulating genetic causes, which some critics think would cause great social harm if they were to be believed. That is, Jensen was replying to the Turkheimers of yesteryear. The scientific task is to get at the facts and properly verifiable…
Continue ReadingIt’s somewhat of an alt right myth that immigrant groups come into the country, and then continuously outbreed the original population even if no more immigration happens. While this maybe have happened historically, it does not generally happen in Western countries because the immigrant groups quickly reduce their fertility levels to the level of the…

Continue ReadingSweden, the land of feminism, of course constantly demands the government produces reports that prove the sex gap in incomes is caused by evil eyes men. So, the bureaucrats attempt to oblige and produce a stream of reports, all of which result conclusions like these: Den statistiska analysen visar att den genomsnittliga löneskillnaden nästan helt…
Continue ReadingSomeone pointed me to data showing a recent very steep decline in incoming migrants. I had a look at the data and plotted it. Unfortunately, the dataset has some problematic missing data that make the decline appear more steep than it is. We’re at 2014 levels, not 2011’s. Main limitation of the below is that…
Continue ReadingIn 2016, a Brazilian PHD student with access to the Brazilian Pelotas dataset was kind enough to run a few regressions for us. We apparently forgot to make the results public, but do so now so others can see. I have also previously analyzed some of this data which was later published in an obscure…
