The nature vs nurture debate was settled long ago. It’s always a mix. Humans have a lot of control over how they behave, but there are definitely inherent predispositions in everyone. They just don’t group nicely along racial lines like bigots believe.
Some people have to struggle a lot harder to behave “correctly” (which depends on societal definitions). Beyond this, there are many different capabilities and preferences. Different people have different natural talents. A ton of that can be altered with learning and training, but some people will improve much faster and will reach higher goals.
The two (main) genders also have a lot of differences as a collective whole. None of that excuses prejudices and limiting people because of the group they are identified with. Any given person can be far outside the norm of their group in terms of what they can do well or do poorly. There are also a lot of perceived differences grounded in social norms that have nothing to do with biological reality. That doesn’t mean there aren’t others that are demonstrable but irrelevant to individual judgments.
The number of people who dwell in the fediverse and think that any two people can accomplish the same thing by putting in the same number of hours astonishes me. It’s definitely influenced by their politics and how they want reality to be.

I hate this study, and I’m not going to forget it anytime soon.
