Positioning the Least Intelligent Presidents in U.S. History

How shrewd are U.S. presidents?

In a recent report, UC Davis educator Dean Simonton utilized historiometric techniques to assess every president's IQ. Simonton broke down data from every president's histories, talks and compositions that would show knowledge.

Simonton evaluated four diverse IQ values for every president. At InsideGov, we found the middle value of each of the four IQs to get our rankings of the 25 slightest keen presidents in U.S. history. Take note of that President Obama was excluded in the review.

With a normal IQ of 128.5, these presidents are still shrewd, yet the bar is set entirely high by the most savvy presidents. For reference, the normal IQ for the overall population is 100.

This rundown is in no way, shape or form authoritative, however it ought to give a general outline of every president's relative knowledge.
