Scott Alexander examines seven cognitive traps that lead doctors to believe they're above-average, potentially applying to other client-choice professions. Longer summary

Scott Alexander explores why doctors often believe they're above-average practitioners. He presents seven cognitive traps that contribute to this belief: 1) Doctors mainly see patients who left worse doctors, 2) Patient retention creates a positively biased sample, 3) Patient departures are often unnoticed, 4) Long-term patients are usually success stories, 5) Doctors are aware of others' mistakes but not their own, 6) Successes are attributed to skill while failures are attributed to circumstances, and 7) Doctors excel at metrics they personally value. Scott suggests these biases might apply to other professions where clients choose their service providers. Shorter summary
