Political bias in science: quotes from Gunnar Myrdal’s 1944 book

Gunnar Myrdal, who was Swedish, expresses an early version of the views the media repeat endlessly these days. To give some examples: White prejudice and discrimination keep the Negro low in standards of living, health, education, manners and morals. This, in its turn, gives support to white prejudice. White prejudice and Negro standards thus mutually…

Recently, I found a Swedish language report that discusses economic consequences of refugee immigration to Sweden. Ruist, Joakim. 2018:3 Tid för integration – en ESO-rapport om flyktingars bakgrund och arbetsmarknadsetablering.

Arab engineer IQ?

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.

Immigrant IQ gains by generation: evidence from PIAAC

Thanks 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).

“a kind of social paranoia, a belief that mysterious, hostile forces are operating to cause inequalities in educational and occupational performance, despite all apparent efforts to eliminate prejudice and discrimination”

Quoting 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…

Fertility of immigrant groups in Denmark by generation

It’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…
