Wow... Hard-core racism, here on HN? And connecting 'accomplishments of races' with modern day policing practices...
Are you even aware of the influence of black people on ancient history? Of the black Roman emperors? Of the black Egyptian Empire, one that was looked at in awe for 5 thousand years?
Are you aware of the inspiration the founding fathers took from the Hodenoshone (Iroquois)?
And in general, are you even slightly aware of how much circumstance and happenstance impact big historical moments?
Either way, you are a perfect example of the kinds of people who invented IQ, and exactly the reasons why it was invented - scientistic veneer to justify racist beliefs, not much better than phrenology before it.
And I sincerely hope you'll get to experience how the kind of policing you praise feels on you own skin. It will hurt, but perhaps it will help you grow as a human being.
Edit: the above comment was heavily edited after my response, removing everything except a link to 1 study.
A published study doesn't make the theory mainstream. This study is heavily criticised in the field, for p-hacking amongst other things. Also their conclusion is about IQ, which itself isn't seen in the mainstream as an indication of general intelligence, so they're really reaching from the get go. You have to have a serious agenda to read this paper and sincerely think the conclusion correct...
