Looking into Crystal Balls: An Experiment on Reputational Cheap Talk
Debrah Meloso, Marco Ottaviani, and Salvatore Nunnari

Do expert motivated by their reputation for being well informed have an incentive to misreport their information? As predicted by reputational cheap talk theory, reporters are more likely to report truthfully when the state of the world is more uncertain and when evaluators conjecture that reporters always report truthfully. However, evaluators have difficulty learning reporters' strategies and tend to overreact to message accuracy, exacerbating reporters' incentives to misreport.
