Does this sound like the set of challenges you might be facing?

• I keep saying I’m certain about this, but the second I imagine actually putting real money on it I get this twist of hesitation
• I’ll declare I’m totally sure about something, but the instant I imagine actually putting real money on it my stomach tightens
• I keep passing on bets that are clearly worth it over the long run, because the sting of the likely small loss looms so much larger than the rare big win
• When something confirms what I already think I swallow it whole, and when something contradicts me I poke holes until it disappears
• I’ve been frozen on this for weeks, telling myself I’ll move once I’m sure

Practices that may help

1. Thinking in Bets
   Annie Duke's thinking in bets framework treats decisions as bets with uncertain outcomes, separating the quality of the decision from the quality of the outcome. Most real decisions involve incomplete information, so good decision-making is about process and probability, not about being right every time. The core skill is evaluating decisions on the information available at the time, not on how they turned out.
2. Translate beliefs into bets to reveal your true confidence
   Would you bet $100 on that belief at even odds? The answer often reveals the gap between claimed and actual confidence.

3. Put stakes on your beliefs — even hypothetically
   Ask: "Would I bet on this?" to separate genuine confidence from performed confidence.

4. Accept positive-EV decisions even when they feel uncomfortable
   If the expected value is clearly positive, take the decision — even if most individual outcomes are losses.

5. Ambiguity Aversion — Why Unknown Odds Feel Worse Than Bad Odds
   Ambiguity aversion, demonstrated by Daniel Ellsberg's 1961 paradox, is the tendency to prefer bets with known probabilities over bets with unknown probabilities — even when expected value is identical or the unknown option may be better. It is driven by discomfort with Knightian uncertainty and systematically steers people away from unfamiliar but potentially high-value opportunities.
6. Update beliefs explicitly when new information arrives
   Treat new information as a reason to state a revised probability, not as confirmation of the old one.

7. Run small bets to convert ambiguity into data
   Replace paralysis with cheap experiments that generate local evidence and reduce uncertainty incrementally.

8. Check the outside view before trusting the inside view
   Ask how similar situations have gone before trusting your story about this specific situation.

9. Check whether the rules of your domain are actually stable
   Before applying any probability model, ask whether the rules governing outcomes could change mid-game.
