Is this the same as "six-sigma" (meaning extremely improbable event that has great impact because its extreme improbability)?
They use "six sigma" also in manufacturing as error level. If a probability of every erroneous task is 6-sigma, the final product is quite unlikely to be defective no matter how complex it is (automobile, etc.)
My IQ is 2.9-sigma, so it is very high (Mensa level is 2.0), but in itself it is meaningless because there are 100-thousands of as intelligent people around.
I saw you mention the sigma thing yesterday and looked it up but still don't really understand it. Basically, a simple definition of a Black Swan is something that comes along (e.g. internet) that most people just don't see coming. It is hard to predict to most. But once it gets a foothold most people look at it and say "Yeah, that was easy to see coming" - as it just makes so much sense - like the internet and like what Bitcoin can and is. I chopped that definition up, but think you get the point.
Regarding a high IQ, not to knock it, but we worship it in the West because it can help to make one a lot of money. But in the grand scheme of things, I would say something more in the direction of emotional intelligence, is more a sign of intelligence. Intelligence should involve many facets, - smarts, compassion, etc. Things that prolong the species and help us to better get along. As it is, IQ tests are self serving to a capitalistic mentality. I'm not knocking you, I love reading your posts, but I'm just saying... To measure a Human Being based on an IQ test, well it's sort of the antithesis of how one should be measured...
