The Ben Franklin Effect

Doing Favors Makes YOU Like THEM

The Counterintuitive Truth

Common sense tells us: we do favors for people we like. But Benjamin Franklin discovered something backwards:

"He that has once done you a kindness will be more ready to do you another, than he whom you yourself have obliged."
— Benjamin Franklin, Autobiography (1791)

In other words: doing a favor for someone makes YOU like THEM more, not the other way around. This seems absurd—shouldn't helping someone you dislike make you resent them more?

In 1969, psychologists Jecker and Landy ran an experiment that proved Franklin right. When participants did a personal favor for an unlikeable researcher, they rated him higher than those who did nothing.
