A good result doesn't mean you decided well, and a bad one doesn't mean you blew it — luck sits in between. Learn to pull the two apart: write your real reasoning down before the result lands, run a pre-mortem on the ways it could fail, and build a Decision Ledger that finally tells you whether your judgment is any good.
A good decision can lead to a bad result, and you keep blaming the choice instead of the luck.
Most of us grade decisions by their outcomes, a habit poker champion and decision scientist Annie Duke calls resulting. It hides the real problem: nearly every meaningful choice is a bet placed under uncertainty, with the odds hidden and the result partly down to chance. This course builds the practical toolkit from Thinking in Bets. You will put numbers on your confidence, ask what usually happens before trusting your gut, run a premortem by visiting the failed future, and keep a decision ledger so you can separate skill from luck over time.
The point is not to be right more often. It is to wager your time, money, and attention more wisely, then learn from each result instead of being fooled by it.
"What makes a decision great is not that it has a great outcome. A great decision is the result of a good process."
Annie Duke, Thinking in Bets
Founders and operators: make high-stakes calls with incomplete information and want a process that holds up when the bet goes wrong.
Investors and analysts: want to estimate odds out loud, lean on base rates, and stop confusing a lucky win with a sound thesis.
Anyone facing a hard choice: a career move or a big purchase, who wants a repeatable way to weigh the odds and review the call later.
