Education, Intelligence, and Performance of the Presidents
When it comes to the presidency, which is better? To have an educated president, or a smart president? Is there any historical pattern of education level or intellect that correlates with success in the office?
To answer these questions it’s helpful to look at the presidents over our entire 233-year-old republic, remembering that 18th century education looked very different than modern schooling. It’s also helpful to have access to scholarly works such as Dr. Dean Simonton’s 2006 work to impute an IQ score for all the presidents. Plus, in modern times, hundreds of historians, professors, and professional observers of the presidents are annually asked by C-SPAN to rank the president’s performance from top to bottom.
Looking into the details of these factors places us at the intersection of education, IQ, and ranking of presidential performance. For the record, all these factors exist through Barack Obama but not yet completely for his later successors.
Education
Our presidents have had a wide range of formal education experiences, ranging from ‘no formal education’ (George Washington and Andrew Johnson), to PhD level (Woodrow Wilson). These big differences in formal education are best understood in the context of the times. Colonial America had fewer choices for formal education, although John Adams, his son John Quincy, and James Madison all graduated from Harvard or Princeton. Most, but not all modern presidents have had access to significant formal educational opportunities.
In addition to these founding fathers, John F. Kennedy, Theodore and Franklin Roosevelt, Barack Obama, and George W. Bush also graduated from Harvard, while Bill Clinton, Gerald Ford, George H.W. Bush, and William Howard Taft all graduated from Yale. Some have gone overseas for parts of their education, such as Kennedy attending the London School of Economics and Clinton attending Oxford.
At the other end of the education scale, Harry Truman and Andrew Jackson had little education beyond high school.
Intelligence
Without getting too deeply into the methodology used by Dr. Simonton, it’s fair to say that assigning an IQ score to the founding fathers is hard to do. That said, no one disputes that John Quincy Adams was by far our smartest president, with an IQ over 168. Not too far behind was Thomas Jefferson at 154, John F. Kennedy at 150, Bill Clinton at 149, and Jimmy Carter and Barack Obama at 145. Given the American average IQ of 100, the lowest presidential IQ, US Grant at 120, is well above average. Indeed the average IQ for the presidents is 135, near the ‘genius’ mark of 140+.
Performance Rank
Which brings us to the question of how well presidents performed in office. Such rankings by C-SPAN’s esteemed historians can be biased and most certainly subject to change over the years. The 2021 rankings:
- Abraham Lincoln
- George Washington
- Franklin Roosevelt
- Theodore Roosevelt
- Dwight Eisenhower
- Harry Truman
- Thomas Jefferson
- John F. Kennedy
- Ronald Reagan
- Barack Obama
As noted, neither Washington, Lincoln, nor Truman had much formal education nor high IQs, yet they are at the very top in performance. They would be called outliers in any analysis.
Washington commanded the highest levels of respect from all corners of the country and his leadership in the Revolution and convocations organizing our founding laws and Constitution made him a legend in his own time.
Harry Truman left office in 1953 with very low approval ratings. Yet over time, historians have pushed him higher and higher in the rankings, mostly for his handling of communist aggressions and setting up long term structures within our government such as the CIA, NATO, Joint Chiefs of Staff, and National Security Council to manage security issues for our country.
More predictably, the two Roosevelts, John F. Kennedy, and Barack Obama had it all going for them: formal education, high intelligence, and they used those skills to perform among the very best.
These ranking exercises and assignment of IQ scores do not easily consider leadership, creativity, character, and personality as critical but subjective factors in a president’s performance. Therefore, they can be debated again and again.
It’s fair to say that the American people are sometimes best served by presidents who are better educated and have higher intelligence levels. However, we must also leave room for tremendous performers who excel as leaders and have personality traits that enable them to succeed whether they achieved high levels of education or not.
