In this research, we surveyed the behavior of escalation of commitment in common organization. In this phenomenon, decision maker, despite receiving negative information and feedbacks from owns primal decision results, still committed to it. Some theories which explains this phenomena, views it with two approaches. The first approach provides dysfunctional and flaw, and the other logically. In this research, we surveyed this behavior and related theories on governmental organizations. The ministry of commerce in Iran was selected as a case study, and a sampling selected randomly at management levels. A questionnaire was given to them and was gathered data. For analysis and hypothesis test linear regression equation was developed. The result shows that the Self justification, Agent and Approach-avoidance theories explain escalation of commitment phenomena on governmental section in Iran.
