I suggest reading through the blog I linked; Haidt is serious and well-respected. Alternatively, you can look at various impartially- (and usually government-) collected statistics that demonstrate group differences. Most of these differences are too incendiary to link here (and I'd rather not attract the wrath of dang), but let me cite one example: men are, biologically, physically much stronger than women. 95th percentile in women is 5th percentile in men. See this well-sourced quora thead: https://www.quora.com/Are-men-generally-physically-stronger-than-women https://www.quora.com/Are-men-generally-physically-stronger-... I think it's pretty easy to corroborate the statistics with everyday experience. Muscular strength is a function of total number of muscle fibers. Look around you, if you're in a group of men and women: which group tends to have the thicker biceps and triceps? Now consider that quite a few people, particularly in the more blue-tribe areas of the US, think that it's a grave injustice that women do not have more representation in occupations that depend to large extent on physical strength --- e.g., firefighting. Think about how frustrating it must feel to point out the unreality of this accusation. Imagine how it must feel to fear that you'd be fired from your job and ostracized from your social group for pointing out what the statistics and your own eyes agree in the truth. Now imagine that you had an opportunity to anonymously vote against the people who make you feel that way. Can you imagine this state of mind? If so, you've captured why Britain left the EU. > My impression of Heterodox Academy is that it's more of the same but regardless, how about finding some more serious sources if you genuinely want to know? One sad effect of the current political climate is that it's become very hard to find unbiased sources --- or at least sources everyone respects (which isn't the same thing).
