Among the many stupid vices I use to numb the Trump pain is sometimes clicking through those idiotic click bait sites like "Celebrities you didn't know were geniuses." Anyway, it turns out that a truly surprising number of them turn out to have an IQ of 160, that is, four standard deviations above the mean (1 in 16,000). Of course you might not be surprised that Bill Gates and Stephen Hawking are credited with that lofty number, but Reggie Jackson, Sly Stallone, and a host of lesser actors are more surprising. I'm pretty sure that 160 is the mode of the distribution. Some guy I never heard of (James Woods) gets credited with a 1/25,000,000 IQ 180.
This entry might give you a clue that the compiler of the list is not quite in that stratosphere:
George Washington was the 1 st President of the United States. Washington was the Commander in Chief of the Continental Army during the Revolutionary War. Washington ushered in the Bill of Rights and Residence Act, authorizing the president to select the seat of permanent federal governance. Washington established a two-term precedent, a law forbidding Presidents from serving more than two terms in office. He had an IQ of 132.5.
It also turns out that IQs are known for practically all Presidents who died before the IQ test was invented.
