Does change of responsibility reduce escalating commitment? A replication and theoretical extension.

Reassigning responsibility is the most prominent and best-replicated intervention against escalating commitment (i.e., the failure to withdraw from losing courses of action). This intervention is considered effective because it reduces reinvestments after negative feedback in decision scenarios with a single reinvestment decision. However, we argue that any intervention against escalating commitment should fulfill two additional criteria. The first is temporal stability, that is, the beneficial effects of the intervention need to persist beyond a single reinvestment decision. The second is specific effectiveness, that is, the intervention should reduce commitment only if the project continues to fail after an initial setback (structural failure) but not if it recovers and is ultimately profitable (temporary failure). To subject reassignment of responsibility to this critical test of effectiveness, we introduce a modification of the escalation paradigm that allows testing for temporal stability and differentiates between structural and temporary failure. In the first of two experiments, we did not find evidence of temporal stability. Experiment 2 found persistent short-term effects of responsibility reassignment, but these effects were unspecific, reducing commitment to both losing and ultimately successful courses of action. Our findings question the usefulness of responsibility reassignment as an effective intervention against escalating commitment. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
