Why you finish movies you hate: sunk cost fallacy

The sunk cost fallacy: why paying for something makes us stick with it, from the 1985 theater-ticket study. For education only, not medical or mental health advice. Studies: Arkes & Blumer (1985), The psychology of sunk cost, Organizational Behavior and Human Decision Processes; Arkes & Ayton (1999), Psychological Bulletin. Stock footage: Pexels.
