Ethics requires symmetry between upside and downside

Taleb's foundational claim is that fair, sound decision-making depends on symmetry: whoever benefits from a good outcome should also suffer from a bad one. When a decision-maker captures gains but offloads losses onto others — shareholders, taxpayers, customers, future generations — the incentive structure quietly rewards recklessness. He illustrates this with the case of a senior banking executive who earned enormous bonuses during a period of hidden, accumulating risk, then departed before the eventual collapse without ever returning the money. Taleb treats this pattern, sometimes called privatizing gains while socializing losses, as one of the most corrosive dynamics in modern institutions, because it looks like skill and foresight right up until the moment the hidden risk detonates. Takeaway: before trusting a decision-maker's track record, check whether they'd have personally lost anything if they were wrong.
