These Are The Most Intelligent U.S. Presidents Ranked By IQ Score – No. 4 is a Surprise

#30. John F. Kennedy – IQ 150.7

Kennedy is known as the youngest person ever to be elected as president, but he was one of the most intelligent. It’s crazy to think about how America would’ve turned out if he wasn’t assassinated.

#29. Bill Clinton – IQ 148.8

Before becoming the 42nd president, Bill Clinton was the governor of Arkansas. He is considered one of the smartest presidents, but that doesn’t mean he had common sense. Which he clearly proved with the Lewinsky scandal.
