Since today is Halloween, I thought I’d discuss the IQ of the king of horror, Stephen King; probably the most successful writer in the history of the genre. When asked what his SAT scores were King replied, in the 1300s. During the the 1960s (when King would have taken the test) the SAT was much more difficult than today. I estimated that if the SAT had been given to all American 17-year-olds in the 1960s (and not just the college bound elite), the mean would have been 760 and the standard deviation about 245; thus a score in the 1300s implies an IQ of anywhere from 133 to 139 (U.S. norms). Let’s split the difference and say 136. That’s higher than over 99% of Americans and speaks to the powerful connection between IQ and creativity, even in a field as non-academic as horror.

To put King’s score in perspective, the average SAT score at Harvard (the most elite school in the World) in 1960 was 1373 equating to an IQ of 138, however Harvard students by definition scored high on the SAT or they wouldn’t be Harvard students so their IQs would likely regress to the 120s (on average) on a randomly selected test. By contrast, for King the SAT was a random test so his 136 would likely not much regress, leaving him to tower not only above 99% of Americans, but even above the average Harvard student!

How does King compare to other super successful writers? When Amy Tan, author of The Joy Luck Club was asked her SAT scores, she replied 1150, which, also in the 1960s, would have equated to an IQ of 124. Based on his memories of taking the WAIS-R I estimated that journalist, author and Fortune Magazine editor Daniel Seligman would have clocked in at IQ 128. JD Salinger scored 104 on an IQ test according to his biography though many find this hard to believe.

So on a scale where Americans average IQ 100 with an SD of 15, great writers seem to average around 119 with an SD of 13. Thus even in a field of creative super achievers, King is a king.

Great scene from Stephen King’s Creepshow (note the kid in the scene is played by King’s real son):
