How Smart Are U.S. Presidents? See The List Of The Least Intelligent U.S Presidents In History

Going to college does not dictate the level of a man’s intelligence. It only goes as far as saying something about your brilliance. But being intelligent goes beyond schooling. It encompasses one’s perspective about life and how best one lives. That is exactly what stunned me in this list.

Some of these presidents did not go to college, yet they are ranked intelligent, infact they were presidents..

See the least of them all…

In a 2006 study, UC Davis professor Dean Simonton used historiometric methods to estimate each president’s IQ. Simonton analyzed information from each president’s biographies, speeches and writings that would indicate intelligence.

Simonton estimated four different IQ values for each president. All four IQs to get our rankings of the 25 least intelligent presidents in U.S. history. Note that President Obama was not included in the study.

With an average IQ of 128.5, these presidents are still smart, but the bar is set pretty high by the most intelligent commanders-in-chief. For reference, the average IQ for the general public is 100.

This list is by no means definitive, but it should give a general overview of each president’s relative intelligence.
