The Ben Franklin effect is a psychological phenomenon where individuals tend to like someone more after performing a favor for them. This occurs due to cognitive dissonance, as people reconcile their actions of helping others with their feelings, often leading them to believe they extend kindness because they have a positive view of the person, even if that's not initially the case.
Benjamin Franklin illustrated this phenomenon when he asked a rival legislator for a favor, which led to increased friendship and civility between them, showcasing how doing a small favor can change perceptions.
To overcome the Ben Franklin effect, be aware of your motivations when helping others and recognize that your feelings towards someone should not be solely based on the favors you do for them.
