jury theorem

• if each voter is right more often than wrong (p > 0.5), majority vote approaches certainty as the group grows
• proved by Condorcet in 1785
• the mathematical foundation of wisdom of the crowds
• in cyber: neurons are the voters. cyberlinks are the votes. the tri-kernel aggregates them into focus — a continuous generalization of majority rule weighted by stake and structure
• the theorem assumes independence. diversity of neurons is what ensures this condition holds
