I'm both a fan of Taleb and Buffett. That said, Buffett's success is due to his strategy of evaluating companies based on a number of characteristics - value investing. It actually aligns very nicely with Taleb's personal investing strategy (as noted in his later book, the Black Swan) of eliminating uncertainty.

Long story short, the less you know, the more "random" events appear to be. As Taleb wrote, "a surprise for the turkey is not a surprise for the butcher." Buffett's strategy is to know/understand as much as possible. Of course you will still be victim of the unexpected, but probably not as frequently.
