We experimentally investigate information aggregation through majority voting when some voters are biased. In such situations, majority voting can have a “dark side”, i.e. result in groups making choices inferior to those made by individuals acting alone. We develop a model to predict how...

This paper reports on experiments testing the viability of markets for cheap talk information. We find that the poor quality of the information transmitted leads to a collapse of information markets. The reasons for this are surprising given the previous experimental results on cheap-talk games....
