A Study of Human Behavior in Online Voting

Plurality voting is perhaps the most commonly used way to aggregate the preferences of multiple voters. The purpose of this paper is to provide a comprehensive study of people’s voting behaviour in various online settings under the Plurality rule. Our empirical methodology consisted of a voting game in which participants vote for a single candidate out of a given set.
