Psychological determinants are those that refer to internal views on the actions and information involved in a project. This can include cognitive factors, personality, and emotions as they relate to project elements. Of these, sunk costs, time investment, decision maker experience and expertise, self-efficacy and confidence, personal responsibility for the initial decision, ego threat, and proximity to project completion have been found to have positive relationships with escalation of commitment, while anticipated regret and positive information framing have been found to have negative relationships.
