I don’t know if I am yet done with the topic of diversity. The discussions about diversity are currently rather intense, and I feel I still have to say quite a bit about it. In general, I have noticed that my position is that diversity is based for at least a considerable part in biology, while those who are on the side of social engineering are of the opinion that it is all culturally determined. In that respect, I discovered a fascinating series of documentaries by the Norse comedian and sociologist Harald Eia, called “Hjernevask“. I haven’t yet completed watching them, but up to now I am pretty surprised about some of his discoveries. The two things that stand out to me are: (1) the role of biology in determining differences between genders and races is much bigger than I had previously assumed, and (2) evidently in “enlightened” western countries such as Norway the thought that differences can be the result of biology is actively shunned even by people whose job it is to know better. Heartily recommended.
