A manager facing a dilemma might consult some of his senior employees, and decide according to the advice of the majority. Should he consult only those on whom he relies most, or let more people share in the decision? We analyze how does the augmentation of a jury by adding two potential jurors influence the probability of making the "correct" choice. We obtain a necessary and sufficient condition for the total correctness probability to increase, assuming that the competence structure of the committee is known. The intuitive meaning of the condition is explained in terms of a certain mean competence.
