well as the value of goal attainment (i.e., rewards minus costs), and thereby generate a subjective expected utility associated with the decision to allocate additional resources." The next phase of the escalation process is self-justification and rationalizing if the decision the leader made used resources well, if the resources being used were used to make positive change, and assuring themselves that the decision they chose was right. Leaders must balance costs and benefits of any problem to produce a final decision. What matters most often in assuring the leader that they made the right choice regardless of the final outcome is if their decision is what others believed in. Research conducted on the topic has been taken from many other forms and theories of psychology. Many believe that what researchers have done thus far to explain this behavior is best analyzed and tested through situational development and resource allocation. Other research has identified circumstances that lead to the opposite of escalation of commitment, namely deescalation of commitment. This research explains the factors that influence whether escalation or deescalation of commitment is more likely to occur through the role of budgeting and mental accounting. Vietnam War Escalation of commitment can many times cause behavior change by means of locking into resources. One of the first examples of escalation of commitment was described by George Ball, who wrote to President Lyndon Johnson to explain to him the predictions of the war outcome: Theories Self-justification theory Self-justification thought process is a part of commitment decisions of leaders and managers of a group and can therefore cause a rise in commitment levels. This attitude provides "one explanation for why people escalate commitment to their past investments." Managers make decisions that reflect previous behavior. Managers tend to recall and follow information that is aligned to their behavior to create consistency for their current and future decisions. If a group member or outside party recognizes inconsistent decision making, this can alter the leadership role of the manager. Managers have external influence from society, peers, and authority, which can significantly alter a manager's perception on what factors realistically matter when making decisions. Prospect theory Prospect theory helps to describe the natural reactions and processes involved in making a decision in a risk-taking situation. Prospect theory makes the argument for how levels of wealth, whether that is people, money, or time, affect how a decision is made. Researchers
