How Smart Should the President Be? A historical analysis suggests a link between IQ and performance
Scientific American ^ | May 26, 2015 | David Z. Hambrick

Do the smartest presidents make the best presidents? This question invariably emerges as a topic of spirited debate when the U.S. presidential election approaches. In 2004, former New York Times Executive Editor Howell Raines asked, “Does anyone in America doubt that Kerry has a higher IQ than Bush?” Citing Bush’s and Kerry’s scores on the Armed Services Vocational Aptitude Battery—an IQ-like test that the military uses to determine whether a recruit is qualified for enlistment—the conservative pundit Steve Sailer countered that there was no doubt that, in fact, Bush had the higher IQ. And the chatter about IQ has begun for next November’s election. Democratic frontrunner Hillary Clinton is “smart enough to handle the job” and “may have a higher IQ than Bill”, while among Republican hopefuls, Jeb Bush is the “smart brother” and Ted Cruz “towers as the smartest presidential candidate”. Wisconsin governor Scott Walker may not be the smartest candidate but “our most intelligent presidents have often been our worst presidents” anyway.

There are three basic views on the relationship between IQ and success in the Oval Office. The first view says the smarter the president, the better. In line with this view, Gary Hart, the retired U.S. Senator and one-time presidential hopeful, argued that although a big part of success as president is picking smart people for key positions, “it takes a pretty keen mind, honed by study, travel, experience, and exposure to competing ideas, to form good judgment and to know whom to trust on complex substantive issues.” The second view holds that you only have to be smart enough to be president. The idea behind this view is that IQ is a “threshold” variable, which loses its predictive power beyond a certain level. Malcolm Gladwell explained this idea in his book Outliers:“The relationship between success and IQ works only up to a point. Once someone has reached an IQ of somewhere around 120, having additional IQ points doesn’t seem to translate into any measureable real-world advantage.” (The average IQ for the general population is 100; an IQ of 120 is at about the 91st percentile.) The final view is that the president can actually be too smart—because, for example, he or she may be unable to communicate on a level that less-intelligent colleagues and constituents can understand. According to one analysis, this is President Obama’s problem: “President Obama is too intelligent for Republicans to understand.” This view puts greater emphasis on interpersonal skills than intelligence. The president is someone you should want to have a beer with, or maybe go bowling with.

What does science say? For obvious reasons, it is not possible to have the 43 U.S. Presidents sit for an IQ test. Thus, in a 2006 study, the University of California Davis psychologist Dean Keith Simonton used a historiometric research approach to estimate the correlation between IQ and presidential success. In the conventional approach to measuring IQ, a person is given a standardized test, such as the Wechsler Adult Intelligence Scale, and their score on the test is assumed to reflect their level of intelligence (with some amount of random error). By contrast, in the historiometric approach, a person’s IQ is quantitatively estimated based on variables having known correlations with IQ, such as highest level of education, academic honors, scores on college admissions exams, occupation, and preferences. In his study, Simonton found that IQ estimates for the first 42 presidents (Washington to G. W. Bush) ranged from 118—around the average for a college graduate—to a stratospheric 165—well beyond the conventional cutoff for “genius.” (The three lowest, from the bottom, were Ulysses S. Grant, Warren Harding, and James Monroe. The three highest, from the top, were John Quincy Adams, Thomas Jefferson, and John F. Kennedy.) What’s more, IQ correlated positively with a measure of “presidential greatness” based on multiple rankings and ratings of presidents’ leadership ability—and the relationship went in a straight line. The smarter the president, the better, roughly speaking. Simonton’s IQ estimates also correlate positively with a ranking of presidential performance compiled by statistician and FiveThirtyEight.com founder Nate Silver.

This finding agrees with results of large-scale meta-analyses by the University of Iowa industrial psychologist Frank Schmidt demonstrating that general cognitive ability—the psychological trait underlying IQ—is the single best predictor of performance in the workplace. It is also consistent with findings from research that has directly tested the idea that IQ is a threshold variable. In a project known as the Study of Mathematically Precocious Youth, Vanderbilt psychologists David Lubinski, Camilla Benbow, and their colleagues found that, even among a sample of intellectually gifted people, a higher level of cognitive ability in childhood forecasted great accomplishment later in life, both in school and beyond. In another study, using four data sets with sample sizes in the thousands, a team of researchers led by the University of Minnesota psychologist Paul Sackett investigated the relationship between cognitive ability and both academic and work performance. In all cases, the relationship was positive and linear—the higher the level of cognitive ability, the better the performance. There was no evidence to support the threshold hypothesis, that there is a “smart enough.”

There is also evidence that IQ is an important predictor of acquiring expertise in specific domains. For example, in a study of 90 Austrian tournament chess players, the psychologist Roland Grabner and his colleagues found that IQ correlated positively with tournament chess rating. (As it happens, over half of U.S. presidents reportedly played chess, and one—Jimmy Carter—aspired to become a chess master after leaving office.) Similarly, in a re-analysis of results of a previous study, my colleague Brooke Macnamara and I found that fluid intelligence—the general ability to reason and think logically—was a strong positive predictor of skill in the board game GO, as measured by a laboratory task that was specially designed to measure a GO player’s ability to evaluate game situations and select optimal moves. In turn, performance in this task was strongly related to a player’s tournament GO rating.

The job of president of the United States calls on a wide range of knowledge, skills, and abilities. The president must acquire vast amounts of knowledge about a dizzying array of topics, consider competing points-of-view and ideas in making decisions, and solve complex problems of all sorts. It goes without saying that IQ isn’t the only predictor of success in this job. Many other factors matter, including experience, personality, motivation, interpersonal skill, and perhaps above all else, luck. Yet, what science tells us is that a high level of intellectual ability translates into a measureable advantage in the Oval Office. As Gary Hart noted, “The Constitution imposes no IQ test”—and it seems safe to assume that it never will. All the same, we should want smart people to run for president, and then we should wish the winner all the luck in the world.

I’m pretty sure you can’t know someone’s IQ without a formal test.

Jimmy Carter was a very intelligent man but a poor president. What we need is a high wisdom quotient.

So how would Lincoln score by those criteria?

This is the most idiotic thing I've ever seen. It might work, sort of, for the last 50 years. Before that, no way.

I think it is utterly ludicrous to rank JFK as they do.

To my mind, Lincoln was probably our smartest president.

I think someone is wrongly associating one's level of formal education with his level of smarts. He's already had significant accomplishments as an executive that I am not aware of others attaining. That's what I call smart.

“President Obama is too intelligent for Republicans to understand.”

AH - HA - HA - HA - HA - HA!

More psycho-babble clap trap!

"it is a great advantage to a president, and a major source of safety to the country, for him to know he is not a great man."

In my judgment, obama has an average, or slightly below average IQ, but he is an accomplished mimic, and thus has been able to dupe many people into believing that he is “articulate and bright and clean.”

The idiots on the left think Obama is smart and Bush dumb. I think Bush is two times or more intelligent than Obama and smarter than the smooth talking con man Clinton. Clinton knew how to work the system, that didn’t make him smart. Obama, well, he gets worked by someone. He is a puppet.

My IQ is probably higher than any US president’s, but I would make a seriously rotten president.

A. I don’t want the job.
B. I’m an introvert, not a team player,
C. I’m short tempered,
D. and probably most importantly, I have very low tolerance for idiots.

With my superior intellect and low BS-threshold, I’d alienate every other country in the world.

I don’t believe IQ has to be all that high, but rather we should judge a candidate on past experience. For example someone like Obama who has the resume of a child - Professional student and he knows how to make phone calls - should not be President.

Carter wasn’t really that smart. I know intelligence is broken down over different types of abilities. However, Carter wasn’t smart. He was well positioned and at the right place at the right time. Same with Obama and Clinton.

Bush, too. Reagan, otoh, was a lot smarter than all of them. Occationally, it happens. Ted Cruz is right there in elite status and might be able to overcome the puppet masters. We will see. IMHO, Thomas Jefferson was our most brilliant leader.

I hope Cruz is of the same clothe.

I would bet that the authors of this study voted for Gore in 2000, and that guy was among the least intelligent SOBs I have ever seen running.

IMHO, IQ tests do not measure real smarts. There are other factors where we can not assign a number. BTW --- Nixon's IQ was probably off the charts. Did he have problems because the Democrats "couldn't understand him"?

Just a wild guess, but I don’t think there is a fat chance in hell that that is the problem.

Am I clairvoyant or what? I knew a delusional sentence like that would be buried in the Sci Am article before I even started reading.

According to one analysis, this is President Obama’s problem: “President Obama is too intelligent for Republicans to understand.”

I have not seen one logical conclusion come from Obama's mouth in over eight years. . . and when he is actually speaking something that is not scripted by other people who are as equally non-gifted as he at drawing valid conclusions, the number of non sequiturs is exponentially increased. He and his puppet masters are singularly inept at seeing logical consequences of their actions, mis-directed actions, and inactions.

Frankly, I don't think Obama would recognize a logic fallacy if one were to bite him on his Democratic Donkey behind.

Obama has shown that he cannot spell Syracuse, he cannot pronounce the word corpsman and he does not know how many states there are in the U.S.

Obama is the only editor who was unable to write a single piece for the law review.

Unlikely his IQ is above 115.
