Dr. John

June 1st, 2008 by reality

Thanks to naked capitalism for pointing out this interview with Nicholas Taleb.

Let me introduce you to Brooklyn-born Fat Tony and academically inclined Dr John, two of Taleb’s creations. You toss a coin 40 times and it comes up heads every time. What is the chance of it coming up heads the 41st time? Dr John gives the answer drummed into the heads of every statistic student: 50/50. Fat Tony shakes his head and says the chances are no more than 1%. “You are either full of crap,” he says, “or a pure sucker to buy that 50% business. The coin gotta be loaded.”

The chances of a coin coming up heads 41 times are so small as to be effectively impossible in this universe. It is far, far more likely that somebody is cheating. Fat Tony wins. Dr John is the sucker. And the one thing that drives Taleb more than anything else is the determination not to be a sucker. Dr John is the economist or banker who thinks he can manage risk through mathematics. Fat Tony relies only on what happens in the real world.
