Action Bias

Taleb has the quote of the day:

There’s something called action bias. People think that doing something is necessary. Like in medicine and a lot of places. Like every time I have an MBA—except those from Wharton, because they know what’s going on!—they tell me, “Give me something actionable.” And when I was telling them, “Don’t sell out-of-the-money options,” when I give them negative advice, they don’t think it’s actionable. So they say, “Tell me what to do.” All these guys are bust. They don’t understand: you live long by not dying, you win in chess by not losing—by letting the other person lose. So negative investment is not a sissy strategy. It is an active one.
