I don't think Taleb is presenting many of these as his original ideas, he's merely (in the original context - his book) using them as examples to drive his other ideas.
If you ask Taleb himself, he would say that he's only had one idea - the rest are just derivations (his or someone else's), and using already observed phenomena and anecdotes to explain it and its consequences.
The only purpose of that article is to expose Dobelli, nothing else.
As to the specific quote Taleb basically reads as a reorganized and edited version of this last quote. - isn't it possible that he has had a very similar experience?
But Taleb's page is also embarassing to Taleb. He's presenting many of these as his original ideas when, well, they're simply not.
