My view is that most people don't talk publicly about windfalls, so if someone's willing to do it on a throwaway it's way more useful IMO to tease information out of him than to marginalize his comments. That's also the best way to determine whether or not he's lying.

If he's consistently lucky, then he's good.

Probabilistic tails are narrow but they do exist. By that, I mean you shouldn't assume that something isn't worth discussing just because it is improbable. That approach stifles the free exchange of thoughts and ideas, and neglects the reality that some people are in fact talented at things that most people can't do.

PS I didn't say you specifically downvoted the guy, but we as a collective have downvoted several of his comments on this article, and you as an individual are trivializing his (claimed) experience as luck.
