Inspired by this comment from polymath:
Sounds like you have a completely freak of nature low tolerance, like bottom 0.001 percentile for baseline THC tolerance.
0.001 percentile is 1 in 100,000 people, roughly equivalent to a person with an IQ of 165 (or 35, going in the other direction) or an American man who is 7 feet tall (or 4’8″).
Now, freaks of nature do happen by simple chance (somebody’s gotta pull the short straw), but let’s consider that my brain certainly seems a bit strange in other ways than low THC tolerance. Also consider, you will not find a white male with 35 IQ whose deficiency is not due to serious brain damage or severe retardation.
To illustrate the pattern, let’s imagine we see a 4’8″ man in the street who also has green skin. That’s odd, we think to ourselves. It’s very strange for a person to have green skin, and pretty rare for a person to be 4’8″. There is probably some sort of common mechanism behind these two rarities, because it is unlikely that they coincided in the same person by mere chance. Perhaps a genetic disease, or his hippy parents only fed him seaweed.
Now, let’s talk about people who completely bust the bell curve. William Sidis was estimated to have an IQ between 250 and 300. I have tracked down the citation and read it; could be false, or lying, but the claim itself is legitimate. 250 is ten standard deviations above the mean, and would correspond to someone being 30 inches taller than average, or 8’4″ (300 IQ ~ 9’2″). That’s not Yao Ming territory, because regression to the mean ensures that even Yao’s kids won’t be anywhere near 8’4″ (they would probably average closer to 6’10”). This is a different species entirely, as in Goliath’s younger brother. You know, like in the Bible:
4 A champion named Goliath, who was from Gath, came out of the Philistine camp. His height was six cubits and a span. [Ed: 9’9″]
1 Samuel 17:4
The chances that such a person would arise from pure genetic coincidence within homo sapiens are laughably negligible, suggesting that William James and Boris Sidis were on to something. Anyway, to conclude the analogy, if you saw a 9’9″ guy in the street with green skin, you would not be remiss to assume he is probably more than a genetic outlier. He is either a mutant or a different hominid.
