Here is an indisputable fact, one of the very few that exist surrounding the mysterious and dreaded Wonderlic Test: the Wonderlic is not meant for football. Over 75 years, only a few thousand of the more than a hundred million test takers have been NFL hopefuls. It is a test of problem solving and cognitive abilities, and has shown a direct correlation with future job performance overall. But football is a different sort of job, one reliant on physical skills, and mental processes that may not involve knowing the age of a boy if his sister is twice his age minus eight.
Does anyone care about the results of the test? Teams don't seem to—plenty of players on the far left of the bell curve have been drafted early. Players sure as hell don't. Leaked Wonderlic scores are only good for troll battles between moralizing writers that will make you dumber for having read them.
Here's another fact: there has never been a study that shows a good Wonderlic score will translate to any sort of advantage on the football field. (This should not be a surprise. Great football players often struggle with the single most widely used intelligence test, then excel. It's called the SAT.) Here's one last fact: there have been several studies that indicate the Wonderlic may be useless, or worse.
One, in 2005, found zero correlation between Wonderlic score and passer rating. Another did find a very specific correlation, but it's not one Wonderlic proponents would like to advertise.
Dr. Brian Hoffman co-authored a 2009 study with Brian D. Lyons in collaboration with California State University (Fresno) and Towson University. The Lyons Study was presented at the 20th and 21st annual Meetings of the Society for Industrial and Organizational Psychology. This 43-page study of 762 NFL players over three draft classes comes to two distinct conclusions:
1) NFL performance on the football field was only found to have a statistically significant correlation with Wonderlic scores among two positions: Tight end and defensive back. Correlations were statistically negligible across all other positions. (Yes, even QB.) In other words, with the exception of TEs and DBs, a player's Wonderlic score (high or low) gave no predictable projection for their eventual productivity as an NFL player. It was worthless.
2)Tight ends and defensive backs showed a (significant) negative correlation.
