Scientific studies done by Catherine Cox and Dean Keith Simonton in 1926 and 2006, (respectively), have determined in order, the Intelligence Quotients of the U.S. Presidents from Washington to Bush…..you might be surprised. I know you’re disappointed that we don’t get to Obama and Trump but maybe someday we will know if their IQ’s are hugely big or huge and bigly.
Just for giggles, write down your guess for the top 3 and see how far off or on you were.
