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.
