Ben Franklin Effect
Doing a favor for someone increases liking for them, as the brain seeks to align attitudes with actions.
Why it works
Based on cognitive dissonance and self-perception theory (Jecker & Landy, 1969), performing favors creates post-hoc rationalization where people increase liking to justify their helpful behavior. The brain resolves the question "Why did I help them?" with "Because I like them," creating retroactive affection. This effect is stronger when favors feel freely chosen rather than coerced (Bem, 1972).
