Don't you think there's a difference between isolated anecdotes and two dozen paragraphs with very similar content? Not to mention the fact that Dobelli reviewed Taleb's book, and that other authors have noticed similarities.

Also this paragraph:

Note that correspondence of content doesn't imply plagiarism. There is a book EXTREMELY similar to Fooled by Randomness called The Drunkard's Walk. Yet not a shade of plagiarism. Why? the examples and terminology were very different. Some ideas can be rediscovered by two people. And when asked, the author said: Had I known about FBR I wouldn't have written that book. An honorable man.

EDIT in reply to above edit: Note that Taleb isn't saying he's the originator of all the examples. Many are attributed in his footnotes, and he's not claming authorship of them. Many of the examples, as you say, are already in the common consciousness. Taleb is using these examples to drive other points. The only thing he is saying - in this article - is showing how Dobelli is obviously plagiarizing what he has written.
