The original Binet IQ test was a good idea - French school teacher Binet used it to decide when to put a child with no birth certificate who did not know his age into first grade, and when to assign a child who we now call “special needs” into classes with special teachers.
A truly weird professor at Stanford University, Louis Terman,
who previously studied termite mounds
modified Binet’s IQ test into what is called the “Stanford-Binet IQ test”
and used it in the 1920s to spot what he believed to be the top 2% of children with an IQ score of 140.
These kids self-adopted the nickname “Terman’s Termites”
There is a book written about them called “Terman’s Kids”
https://www.kirkusreviews.com/book-reviews/joel-n-shurkin/termans-kids/Louis Terman believed they would be the next Nobel Prize winners - but none of these children with 140 IQs did,
while two students with 120 IQs that he tested and rejected did win Nobel Prizes.
Another professor - this time at Harvard U - studied high IQ Harvard students and compared them to matched Boston children who did not go to college in a long running study.
Dr Valiant found that in both the Harvard kids and the Boston kids there was this trend - the higher the IQ the more likely the child would become an alcoholic.
Valiant wrote a good book: What You can Change and What You Can’t
If you go to a few MENSA meetings the amount of heavy drinking is noticeable, kinda the opposite of AA
Maybe I should rethink my position.
