43 American Presidents Ranked In Order Of Their IQs

43. Ulysses S. Grant – 130

Ulysses S. Grant may be low on this list, but that doesn’t mean he was dumb by any stretch. Nowadays, in fact, his estimated IQ of 130 is a whole 32 points above the average American’s. Grant was the 18th president, serving two terms from 1869, although he’s arguably just as well-remembered as a Unionist Civil War general. And since he was on the winning side of the conflict, that suggests he was indeed pretty smart after all.
