The effecitiveness of the unanimity rule with sequential voting when jurors are unfair.

我们分析了评审团必须对一组参赛者(例如体操比赛或手工艺竞技表演)进行排名的问题，这些参赛者的社会最优排名是陪审员中的常识。他们可能在参赛者中有朋友，因此可能偏向于他们的朋友。结果表明，采用公开投票的顺序投票代替无记名投票，作为陪审团的集体决策方法，可以有效地使陪审团选择出社会最优的排名。

We analyze the problem of a jury that must rank a set of contestants (e.g., gymnastics competitions or competitive shows of crafts) whose the socially optimal ranking is common knowledge among jurors. They may have friends among the contestants and may, therefore, be biased in their friends' favor. We show that sequential voting with open ballot instead of secret ballot, is effective as the jury's collective decision-making method to make the jury select the socially optimal ranking.
