Group decisions under ambiguity: Convergence to neutrality

  • Keck, Steffen
  • Diecidue, Enrico
  • Budescu, David V.

This paper focuses on decisions under ambiguity. Participants in a laboratory experiment made decisions in three different settings: (a) individually, (b) individually after discussing the decisions with two others, and (c) in groups of three. We show that groups are more likely to make ambiguity-neutral decisions than individuals, and that individuals make more ambiguity-neutral decisions after discussing the decisions with others. This shift toward higher ambiguity neutrality in groups and after a group discussion is associated with a reduction in the rates of both ambiguity aversion and ambiguity seeking. We suggest that the results might be driven by effective and persuasive communication that takes place in groups.
