Dr. Orestis KOPSACHEILIS is now an Assistant Professor of Behavioral Economics at the Technical University of Munich. He earned his Ph.D. in Economics from the University of Nottingham, UK in 2019. His research interests include focuses on decisions under uncertainty in individual and social contexts as well as the ensuing policy applications to high-risk decision areas such as medical decision making. He is also working on the intersection of collective intelligence and machine learning. His papers have been published in Theory and Decision, Journal of Risk and Uncertainty and MBC-Public Health.

Conditional cooperation is usually investigated in experiments where the choices of others are known. In many circumstances, however, there is uncertainty about others' cooperativeness. Using a novel experimental protocol, we manipulate the perceived likelihood of cooperation in a Prisoner's Dilemma, and whether such information is described unambiguously or learned through experience and thus ambiguous. We report on a 'description-experience gap' in which rare events appear to be more influential under experience than under description. This contrasts with earlier results from the individual choice literature. We show how stronger priors under social than individual uncertainty can account for this reversal.
