Every decision is a bet on an uncertain future

Duke's foundational reframe is that decisions aren't really different in kind from bets—both involve committing resources (time, money, attention) toward a future outcome you can't fully control or predict. Choosing a job, a restaurant, or a spouse involves the same underlying structure as calling a poker hand: you have incomplete information, some probability distribution of outcomes, and a choice to make anyway.

She argues most people resist this framing because "betting" sounds reckless or gambling-adjacent, while "deciding" sounds sober and controlled—but the linguistic comfort of "deciding" hides the same uncertainty a bet openly admits to. Poker forces this honesty onto players immediately: fold or call, and the cards don't care how confident you felt.

Duke's point isn't that life is a casino—it's that pretending our decisions are more certain than they are leads to worse thinking, because we stop asking the right question ("what's the probability this works, and how confident am I really?") and start asking the wrong one ("was I right or wrong?").

Takeaway: Before deciding, explicitly ask what odds you'd assign to different outcomes—don't skip straight to a verdict.
