George W. Bush – IQ 138.5
Contentiously, George W. Bush was known for not being able to capture the audience’s attention and unpopular policy decisions. While the former president did forge a tremendous political career for himself, his school and college grades suggest that he wasn’t the best student.
Nevertheless, the man holds the distinction of being the only country head who entered the office with an MBA! The popular columnist David Brooks once famously quipped that Bush Junior’s IQ seemed 60 points higher when one met him in person. Maybe this was an act all along?
