Previous research suggests that decision makers have the tendency to keep on investing in losing courses of action. The present study focuses on de-escalation and proposes causal loop diagrams as a technique to decrease escalating commitment in a failing action. The effectiveness of causal loop diagrams is also contrasted with the effect of receiving a list of important factors. Causal loop diagrams were found to decrease commitment as compared to having no decision aid. However, no significant difference was found between causal loop diagrams and a list of important factors as a de-escalation technique.
