I agree for hard science, but I see more wishful thinking about society on the "left". A lot of the rhetoric about social justice implicitly hinges on the Blank Slate theory, the assumption that all (groups of) people would, in a vacuum, have exactly the same statistical outcomes. Therefore, all deviations from the average must automatically be a sign of systemic discrimination. When you look at studies, the situation is rarely as clear-cut.

The same is true with the "diversity is strength" mantra, where everyone seems to cite that one feel-good McKinsey study as if that told the full story.

This kind of naivety is not as bad as burning the planet, but at the end of the day, it's still people looking at studies and saying "can't be true".
