Habit formation, self-deception, and self-control

Recent research in psychology suggests that successful self-control is attributed to developing adaptive habits rather than resisting temptation. However, developing good habits itself is a self-regulating process, and people often fail to accumulate good habits. This study axiomatically characterizes a dynamic decision model where an agent may form a deceptive belief about his future preference: the agent correctly anticipates his future preference by considering the effect of habits; however, he is also tempted to ignore the habit formation. Self-control must be exerted for resisting such a self-deceptive belief. Our model is flexible enough to accommodate a variety of habit formation and explains behavioral puzzles related to gym attendance, self-control fatigue, and demand for commitment.
