Black people make up 13% of the US population, but only 1.2% of lead researchers on biomedical studies are black.
does anyone see a problem with this? you would only expect 13% of bio researchers to be black if bio researchers are of average intelligent.
If bio researchers are higher on the intelligence bell curve, simply because there are not as many blacks as there are whites would cause that number to deviate significantly from 13%. Even if the capabilities between blacks and whites follow the same distribution.
What I'm trying to say (making up numbers for simplicity), is that if you need an IQ of 110 to be a researcher, and thats 1/5 people for both black and white because they are equally capable. If there are 10 times more white people (90% white), you would expect 1/50 blacks (2%) to be researchers. not 1/10 (10%) because even though the odds of a 110 IQ are the same, there are fewer occurrences simply because there are far less blacks than whites.
I'm sure I messed up the calculations here but you get the idea right?
