The US does not have the highest incarceration rate in the world:

It's 4th, and the difference between the US and the next few dozen isn't that significant. Also, you are assuming cause and effect. The US is a rich, well developed country with an unusually high black population due to slavery. The much simpler explanation is that the black population are much more criminally inclined. The fact that their average IQ is significantly less is explanation enough: criminality is closely tied to IQ.

I hope you know that IQ is also a defined test one can improve results by training for it. It is nothing genetically fixed in the IQ-test. When I did ask Claude for high correlations of crime and murders, then claude lists the following:

Additionally does the map you shared showcase very clearly, that it is among the top incarceration rates worldwide. It is a well known thing in social science, that most prisons within the US lack models to focus on reintegration of prisoners. Prisons are rather criminal highschools, than helping those who need it the most to find a way to live a successful life, with a legal job and a house over the head. I mean to most people it should be clear, that prisoners are some of the weakest link within society. They are not there for being very social, skilled and useful. So it is kind of obvious they need a lot of training in getting there in order to become a good neighbour after prison.

So it's the low IQ not the black skin? Why don't you propose to incarcerate the whole low IQ population instead of just the black portion?

You are just making stuff up now. I clearly proposed to enforce laws equally, and allow the results of that to happen as they may:

Your post at the top of the thread says "black".
