Diagnostic Panel Wisdom-of-Crowds Simulator

Each doctor on a diagnostic panel is only slightly better than a coin flip at telling an explainable case from a genuine anomaly. Watch the Condorcet Jury Theorem in action: as the panel grows, majority-vote accuracy climbs toward certainty far faster than any individual doctor ever could — unless the doctors stop judging independently.

This simulator puts a panel of N doctors in front of an ambiguous case — is it an explainable medical phenomenon or a genuine anomaly? — where each doctor, alone, is only individually-better-than-random at calling it correctly. Tune the panel size and each doctor's individual accuracy, and watch the exact Condorcet Jury Theorem formula predict how fast majority-vote accuracy should climb toward certainty. Then flip on correlated judgments to see why the theorem's independence assumption is not a technicality: when doctors start copying a shared bias instead of judging on their own, more panelists stop helping.

⚙ Under the hood

This simulation demonstrates how averaging many independent diagnoses converges to the true pollution level faster than any individual doctor can.
