Epistemic Democracy and the Aggregation of Citizen Competence
Quick fact
The Condorcet Jury Theorem shows that if each voter has a probability greater than 1/2 of being correct, the probability that the majority picks the correct option approaches 1 as the number of voters increases. Even with a competence of just 0.51, a large enough jury is virtually guaranteed to be right.
Why this is interesting
Imagine a group of voters with only a slight edge over a coin flip—yet, when they all vote, the group can become almost infallible. How is that possible?
