In games of “chicken”—canonically, two teen boys drive their cars toward one another at breakneck speed, the one who swerves is “chicken” (and if neither swerves, then both lose and it’s small consolation to either that neither is “chicken”)—there are two ways to make the other guy swerve. One is a commitment mechanism: Tie down the steering wheel so it won’t swerve, jam the accelerator full down with a broom stick, and jump into the back seat. The second is to have the reputation of being crazy, as in being crazy enough not to swerve.
Acting crazy gets less respect than it should as a winning strategy in politics and other areas. North Korean dictators are given a wide berth in international affairs because the international community thinks they’re crazy. Overseas, George W. Bush was widely decried as a crazy belligerent. I often wondered whether he invited the reputation intentionally.
