When was the IQ tested? Methods of testing IQ are different when Washington was president compared to now. At what age? Joe Biden most certainly does not have 149 IQ currently.
Agree!
IQ score depends on the test. On some tests the genius leel score is 130. On others 160. Score is meaningless unless there’s a way to conciliate the different scores. Mensa uses the standard of a score in the top 2 percent on any standardized test. That said, this report is BS. There’s no reliable way of measuring an IQ from two centuries ago.
