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

• There’s one area I consider myself an expert in, and that’s exactly where I’m most stubbornly sure and most often wrong
• The stuff I’m most certain I’ve nailed is exactly what blindsides me on the test
• I feel completely sure about this decision, which is honestly starting to make me nervous
• I’m good at my actual job, but lately I keep wading confidently into the next thing over
• I’d jump on this in a heartbeat if it were the familiar version, but because it’s in a world I don’t know I’m demanding way more proof before I’ll touch it

Practices that may help

1. Identify the specific domains where you are most overconfident
   Calibration is domain-specific — find where your confidence most exceeds your accuracy.

5. Check whether you’re demanding an unfair ambiguity premium
   Estimate what you’d accept under comparable known-odds risk — if your bar is much higher for unknown odds, that gap is the bias.

6. Separate “the world is uncertain here” from “I don’t know enough yet”
   Ask: would a domain expert still face this uncertainty? If not, the issue is a skill gap — not fundamental ambiguity.

7. Practice confidence interval estimation
   Estimate ranges for factual quantities and check how often the true value falls within your range.

8. Watch for the signatures of overconfidence
   Treat "this is obvious" and "I’ve got this" as warning signs, not green lights.

9. 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.
10. 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.
