Can group decision-making mitigate propensity of escalating commitment？ ―An experimental research based on the prospect theory

Abstract

Escalation of commitment is a well-known investment trap, which is irrational from an economic point of view but inevitable due to psychological factors. Based on a role-playing experiment, this paper intends to analyze the impact of different effects of the prospect theory on the tendency of escalating commitment in different decision-making processes, and discusses whether certain decision-making processes can mitigate the tendency of escalating commitment. Our empirical results indicate that groups with prior individual consideration can make better decisions involving effects of the prospect theory than individuals and groups.
