And third of all, the same way you round up so that you’re 6’0 on OKCupid, NBA players round up so that they’re 7’0 on their official stats. Second of all, at this height talent scouts comb the world for suitably tall foreigners and import them, so we can no longer assume we’re drawing from the pool of tall Americans. ![]() First, at this height people with very rare medical conditions and pituitary tumors start taking over from normal variation, so we lose our ability to derive a census a priori with pure math. But he adds several complicating factors. Sports Illustrated‘s Dan Diamond does a similar analysis and gets broadly similar results. So about 8 out of 9 people of this height are in the…wait, no, that can’t be right. So about one in every 30 people of this height is in the NBA.Ġ.00002% of the US male population is 7’0 to 7’3, which corresponds to about 45 men. So about one in every 1,500 people of this height is in the NBA.Ġ.003% of the US male population is 6’9 to 7’0, so about 5,000 men. So about one in every 40,000 people of this height is in the NBA.Ġ.15% of the US male population is 6’6 to 6’9, so about 200,000 men. So about one in every 500,000 people of this height is in the NBA.Ģ.35% of the US male population is 6’3 to 6’6, so about 4 million men. So about one in every 11 million people of this height is in the NBA.ġ3.5% of the US male population is 6’0 to 6’3, so about 21 million men. We can do some very rough Fermi calculations for the next couple standard deviations.ģ4% of the US male population is 5’9 to 6’0, so about 54 million men. If we’re going to stick to our resolution to use the histogram we’ve got, the contribution of the left half of the height bell curve is precisely zero. The all-time record holder is Tyrone “Muggsy” Bogues at 5’3, who was actually pretty good (though not above exploiting his distinction for publicity: his autobiography is called In the Land of Giants ). This is not true eternally and forever – Wikipedia’s List Of Shortest NBA Players names 25 NBA players in history (out of maybe 5000 total) who were below average stature. The first thing we notice is that nobody shorter than average (ie 5’9) gets in. So let’s see what we can learn from the height distribution of every player in the NBA: ( source) It’s another strongly heritable polygenic trait which is nevertheless susceptible to environmental influences, and which varies in a normal distribution across the population – but which has yet to accrete the same kind of cloud of confusion around it that IQ has. ![]() Since z-scores are magic and let us compare unlike domains, we conclude that eminent theoretical physicists are about as smart as pro basketball players are tall.Īny time people talk about intelligence, height is a natural sanity check. Both of these are a little over three standard deviations above their respective mean. The average NBA player has a height of 6’7. ![]() The average eminent theoretical physicist has an IQ of 150-160.
