The phrase "skin in the game" is one we have often heard but have rarely stopped to truly dissect. It is the backbone of risk management, but it's also an astonishingly complex worldview that applies to all aspects of our lives. Nassim Nicholas Taleb pulls on everything from Antaeus the Giant to Hammurabi to Donald Trump to Seneca to the ethics of disagreement to create a tapestry for understanding our world in a brand new way. Among his insights: For social justice, focus on symmetry and risk sharing -- Ethical rules aren’t universal -- Minorities, not majorities, run the world -- You can be an intellectual yet still be an idiot -- Beware of complicated solutions (that someone was paid to find) -- True religion is commitment, not just faith.
