TB: Skin in the Game

Having personal exposure to the consequences of one's own decisions and advice. Those with skin in the game bear downside risk for bad outcomes, not just upside from good ones. The principle demands symmetry: no advice without accountability, no profit without possible loss.

Skin in the game is Taleb's cure for the problem of "talking without doing." Advisors, consultants, pundits, and bureaucrats often make consequential recommendations while bearing no personal cost if those recommendations fail. This asymmetry produces systematically bad advice — the recommender captures upside (fees, prestige, influence) while others bear the downside (losses, harm, failure). Skin in the game also serves as an epistemological signal: people who act on their beliefs reveal their true credences. Watch what people do with their own money and time, not what they say.

• Antifragile (Taleb): the "Bob Rubin trade" — traders who collect bonuses in good years and keep them in bad years; asymmetric payoffs without skin in the game produce reckless behavior; the solution is clawbacks and personal liability
• Fooled by Randomness (Taleb): lucky traders vs. skilled ones — those with skin in the game eventually blow up or survive; the filter of time and personal exposure separates genuine skill from noise

• Antifragility — antifragile systems require skin in the game; fragility is often hidden until someone with no skin in the game makes a decision that exposes it
• Lindy Effect — things with skin in the game (that could die from failure) have been filtered by survival
• Rationality — Moral Duty to Be More Rational — skin in the game makes rationality have real stakes
