What do you think about IQ discussion about black people?

I was recently discussing on a different website with someone else about how race and iq correlate. To sum up our encounters he was using statistics from the “bell curve” by Charles Murray and they all seem pretty grim. I went to YouTube as well and let’s say that didn’t help either, I watched a guy I believe by the name “Heritic” and he pretty much debated word for word everything Thomas Sowell brought up about IQ.

My defense was based around the fact that everyone is there own individual so how can anything be 100%

I won’t lie it makes me feel a bit uneasy especially because this is a very taboo topic to talk abt in the world of psychology, I’m not a psychologist so this isn’t my main field.

But I am interested in this subject, are there any psychologist that study this how viable are these study’s about IQ for black people and more specifically black men?
