The Dark Side of the Vote:Biased Voters, Social Information, and Information Aggregation Through Majority Voting
نویسندگان
چکیده
We experimentally investigate information aggregation through majority voting when some voters are biased. In such situations, majority voting can have a “dark side,”that is, result in groups making choices inferior to those made by individuals acting alone. In line with theoretical predictions, information on the popularity of policy choices is beneficial when a minority of voters is biased, but harmful when a majority is biased. In theory, information on the success of policy choices elsewhere de-biases voters and alleviates the ineffi ciency. However, in the experiment, providing social information on success is ineffective and does not de-bias voters. JEL-codes: C92, D7, D02, D03

متن کاملDouble voter perceptible blind signature based electronic voting protocol
Mu et al. have proposed an electronic voting protocol and claimed that it protects anonymity of voters, detects double voting and authenticates eligible voters. It has been shown that it does not protect voter's privacy and prevent double voting. After that, several schemes have been presented to fulfill these properties. However, many of them suffer from the same weaknesses. In this p...
متن کاملInformation Aggregation and Strategic Abstention in Large Laboratory Elections
Recent advances in voting theory have shed light on the influence of pivotality on voter choices when voters have asymmetric private information, and the implications of this for information aggregation in committees and elections. Of particular interest is the result that voters may optimally choose to vote contrary to their own private information, even in committees or elections where all vo...
