What is the Ben Franklin effect?

The Ben Franklin effect is when someone likes you more after doing you a favor [1][2]. It's like when you help a friend with their homework—afterward, you feel like they're a better friend, even though nothing changed about them [1].

Why does it happen?

Your brain gets confused about why you helped someone [1]. Instead of thinking "I'm a nice person," it thinks "I must really like this person, or I wouldn't have helped them" [2]. It's like your brain working backwards to figure out what you feel [1].

What does it feel like?

Imagine lending your toy to someone you didn't really like [2]. After you lent it, you might suddenly feel closer to them, because you wouldn't have shared if you didn't care [3]. The favor makes you think you care about them [1].

How do you use it?

If you want someone to like you, you can ask them for a small favor [4]. When they help you, their brain will trick them into liking you more [2][4]. It works best with small favors like borrowing a pen or asking for advice [5].
