Are NFL Players Smart?

This entry was posted on 1/4/2007 11:51 AM and is filed under Psychology, Sports.

My friends and I have often debated whether the average IQ in the NFL is higher or lower than the average of the general population. Conventional wisdom probably holds that NFL players have below average intelligence. I always argued the contrary position, that NFL players would score above average on an intelligence test. I figured there was something to the mental aspects of the game that would favor smart players. I also figured that going to college might lead to a higher score.

So, there is actually some evidence to answer this question. The Wonderlic Test is administered to potential NFL players before the draft. The same test is also administered to all kinds of people entering various professions. The average score on the Wonderlic is twenty, which is supposed to correspond to the average IQ of 100. A recent ESPN article shows the average Wonderlic scores for NFL players by position; it provides some sample questions too. It turns out that the average score for an NFL player is actually twenty-one, which is exactly the same average score among American workers.

Now I would really like to know how a person’s Wonderlic Test score compares to the scores of real IQ tests such as the Stanford-Binet or the Wechsler Adult Intelligence Scale (WAIS.) How accurate is the Wonderlic Test anyway?

      The Wonderlic is a "fit" based intelligence test designed for NFL players more so than a pure or raw intelligence measurement. The WAIS or WASI are more accurate measures of raw intelligence. The Wonderlic is not nearly as comprehensive since it is only a twelve-minute, fifty-question exam, whereas the WAIS or WASI containing 14 grouped sub-tests and takes several hours to administrate (my wife does this for a living). Additionally the Wonderlic is only looking at Adult male intelligence, which is not a representative sample of the requisite population and thus is not a very good comparable to a standardized intelligence test for the general public.

      According to the ESPN article, the same Wonderlic that's given to football players is given to millions of employees.

      Yes, the "real" IQ tests are obviously in a totally different league than the Wonderlic. Test scores for given individuals on the two tests would certainly be correlated, but I wonder how close they would be. I wonder if anyone or if Wonderlic has studied and compared actual results of the different tests.

      There would probably have to be a validation study between the 2 different tests of the same subjects taking both and then the r coefficient would have to be assigned based upon creation of a multiple linear regression. Typically an r value (correlation) of .3 or higher would be considered significant (where 1 is 100% correlated and 0 is 0% correlated). I'll look to see if there is one out there (probably does exist).

      Here is another ESPN article about the Wonderlic. The most interesting part describes how scores on the test may or may not be correlated with being a good football player.
