Why should we never listen to people who explain rather than do? Why do companies go bust? How is it that we have more slaves today than in Roman times? Why does imposing democracy on other countries never work?

The answer: too many people running the world don't have skin in the game. In his inimitable, pugnacious style, Nassim Nicholas Taleb shows that skin in the game applies to all aspects of our lives. It's about having something to lose and taking a risk. Citizens, lab experimenters, artisans, political activists and hedge fund traders all have skin in the game. Policy wonks, corporate executives, theoreticians, bankers and most journalists don't.
