You ask a coworker for help with a project. They assist. Now they like you more than before, even if they were neutral before. The favor created liking.

The Original Discovery

Ben Franklin noted in his autobiography that an enemy who did him a favor became his friend. He theorized that people rationalize their actions: ‘I helped them, so I must like them.’ Used in persuasion research to show how requests increase liking.

How It Works in Real Life

The Ben Franklin Effect isn’t a rare phenomenon—it’s everywhere once you start looking:

  • An enemy hears you’re in trouble and helps. Instead of increasing resentment, the help starts to turn them into a friend. Actions change feelings.
  • A customer service rep goes the extra mile for a customer. The customer not only appreciates the service but develops loyalty because of the effort the rep put in.
  • You ask someone you’ve been distant from for advice. They give it. Now you’re closer. The request created connection.

Why This Matters to You

The Ben Franklin Effect is counterintuitive: vulnerability and asking for help increases liking, not decreases it. If you want someone to like you more, ask them for a favor (one that’s reasonable and within their ability). It works better than doing favors for them. This is why mentorship works: the mentor invests in the mentee, so they grow to care about them. It’s why teachers develop relationships with students who ask questions. Asking creates connection.
