The option with the most votes will be chosen by the jury. In the N-couple model of Althöfer and Thiele (Theory and Decision 81:1–15, 2016), the jury consisted of 2N agents. These agents form N independent couples, with dependencies …

Im trying to proof the non asymptotic part of Condorcet's jury theorem: "In a homogeneous committee composed of n=2k+1 independent experts with the same expertise 0.5 < 𝑝, any addition of an even number of specialists with expertise 𝑝 increases the probability of the majority rule being ... WebCondorcet's Jury Theorem shows that on a dichotomous choice, individuals who all have the same competence above 0.5, can make collective decisions under majority rule with a competence that approaches 1 as either the size of the group or the individual competence goes up. The theorem assumes that the probability of each voter's being correct is … WebWith the aid of a simple discrete probability model, the Condorect Jury Theorem is extended to situations where there is dependency between judgement. It is shown that negative intra-voter correlation improves on jury competence in the sense that the probability of a correct decision increases. Positive correlation, on the other hand, tends … molly put the kettle on
