The U.S. Presidential IQ hoax was a mid-2001 e-mail and internet hoax that purported to provide a list of estimated IQs of the U.S. Presidents from Franklin D. Roosevelt to George W. Bush.

It was reprinted as if factual by the ever-gullible Guardian, and was cited in a Doonesbury cartoon as if it represented reality.

In reality, we have a good handle on only three Presidential IQs.

JFK was tested at 119 by his prep school.

President Bush the Younger scored 1206 on the pre-1974 SAT, which converts to an IQ of about 129 on the Otis scale. (There was a close correlation between SAT and IQ in those days. The correlation was dependable enough that MENSA accepted a 1250 score for membership at that time. Over the years the tests have been revised, the correlation no longer exists, and MENSA no longer accepts SAT scores in its admission process.)

Richard Nixon was one of the gifted students studied by Terman in his longtitudinal study. Nixon biographer Roger Morris says RMN tested at 143 when he was in Fullerton High School in California.


Al Gore was never elected President (or was he?), but we also have a pre-1974 SAT score for him. He scored 1355, which is equivalent to about 137-138 on the Otis scale, and would place him in the upper 1%, about in the same league as Nixon.
