What is the Ben Franklin Effect?

The Ben Franklin Effect is a psychological phenomenon where a person who has already done someone a favor is more likely to do another favor for that person, compared to if they had received a favor from them. This counterintuitive effect suggests that we tend to justify our actions by adjusting our attitudes: if we help someone, we are likely to conclude that we like them, because we wouldn’t help someone we dislike.

Historical Anecdote

The effect is named after Benjamin Franklin, who famously turned a political rival into a friend by asking to borrow a rare book. After the rival obliged, Franklin returned the book with a note of thanks, and the two became friends. Franklin wrote in his autobiography: “He that has once done you a kindness will be more ready to do you another, than he whom you yourself have obliged.”

Practical Applications

  • Building Relationships: If you’re trying to create a relationship, or even turn an enemy into a friend, you might consider what small favor you can request, rather than what you can give.
  • Conflict Resolution: Asking for help from someone you are in conflict with can soften their stance and open the door to reconciliation.
  • Leadership & Influence: Leaders can use this effect to build rapport and trust within teams by inviting contributions and assistance.
