They will never, ever admit a 20 point IQ gap, on average.
Anyone who has a job cannot utter it, even amongst friends.
But us retired folks can speak the truth.
There’s a 20 point IQ gap!!
And you can’t fix stupid.
I did not independent research one time because I found the debate to be interesting.
In tests that are adjusted for culture and education, in the US and all over the world...there seems to be a gap.
Of course, unless you were looking at results from the 60’s the authors would go overboard telling you all of the reasons why this “might” be true.
The data supported the gap. No one wanted to believe the data.
Unnecessary.
"Different" is the issue.
