Reply #17: This is probably more realistic...

Back in 1999, Charles Murray, co-author of The Bell Curve, and I
estimated from Bush’s SAT of 1206 (about 1280 under the easier
scoring system adopted in 1995) that his IQ fell somewhere around
the 95th percentile. The late leftist historian Jim Chapin estimated
that Bush’s IQ of roughly 125 probably falls in the second quartile
of presidents, a little below average, while Al Gore, who scored
about 10 points higher, was in the third quartile. You don’t have to
be a genius to be president.
