Famous hereditarian Arthur Jensen found that <70 IQ (intellectually disabled) white kids acted "abnormally" while black kids with the same score act "normal"

Instead of questioning the metric, they just decided that black folks adapted well to being intellectually disabled.

Many hereditarians will tell you they consider 16% of African Americans and 50% of Africans to be intellectually disabled (old term was mentally ret*rd*d). I simply didn't realize that many just believe we function differently under that designation.

I honestly didn't know this was a thing. I've been in a couple conversations lately where it seemed like a struggle to get a hereditarian to say things which were logical consequences of their positions.

I had no idea there was this huge logical hole sitting right there

But seriously, doesn't common sense say that if
- IQ is a universally fair metric

And:
- IQ <70 implies intellectual disability
- Black people with IQ <70 don't match expectations of intellectual disability

Then... maybe IQ isn't a universally fair metric?

The question about the metric is the easy part. Just imagine being so convinced that black folks are intellectually inferior that one can just shut their brains off when it comes to a logical gap that should make one question everything.
