:Information technology (IT) projects can fail for any number of reasons, and can result in considerable financial losses for the organizations that undertake them. One pattern of failure that has been observed but seldom studied is the runaway project that takes on a life of its own. Such projccts exhibit characteristics that are consistent with the broader phenomenon known as escalating commitment to a failing course of action. Several theories have been offered to explain this phenomenon, including self-justification theory and the so-called sunk cost effect which can be explained by prospect theory. This paper discusses the results of a series of experiments designed to test whether the phenomenon of escalating commitment could be observed in an IT context Multiple experiments conducted within and across cultures suggest that a high level of sunk cost may influence decision makers to escalate their commitment to an IT project In addition to discussing this and other findings from an ongoing stream of research, the paper focuses on the challenges faced in carrying out the experiments.
