Edit window closing, and I don't like my level of snark. So slightly more verbosely:

IQ is a factor that predicts a host of abstract reasoning skills, but correlates strongly with nearly every metric required for success in modern society. While I agree with you that "being a world champion at anything" requires remarkable ability, including (variously) the ability to struggle, work hard, endure hardship, etc., those things are not IQ-related, and the distinction matters. IQ is, as best as has been determined, the most important factor for general success, and certainly success in the modern world, that has ever been found.

Well, aside from being born rich. But that's a different success metric.

Anyway, I don't have the guy's testing results, and I don't feel great about having an extended debate on what Tyson's IQ is, so that's as much as I'll say on the matter.
