What is the Benjamin Franklin effect?

The Benjamin Franklin effect describes how doing a favor for someone can actually make us feel more positively towards that person. The phenomenon is named after Benjamin Franklin, one of the Founding Fathers of the United States of America, who wrote about the concept in his autobiography. 

Where this bias occurs

Imagine you have a co-worker, Alice, whom you don’t particularly like. You’ve had some disagreements in the past and you generally don’t have a good impression of her. One day, Alice asks for your help with a project she’s working on and you agree to assist her, even though you’re not thrilled about it. 

As you work together on the project, you find that Alice is appreciative of your assistance and is friendly and grateful. You see her dedication and hard work and you start to understand her perspective and skills better. As you continue to collaborate, you gradually start to develop a more positive opinion of Alice. 

Over time, you realize that you actually enjoy working with her and that your initial negative feelings have turned into a more favorable impression. This shift in your attitude towards Alice is an example of the Benjamin Franklin effect. By doing Alice a favor and working together on the project, you’ve come to like her more, despite your initial reservations.

I was blown away with their application and translation of behavioral science into practice. They took a very complex ecosystem and created a series of interventions using an innovative mix of the latest research and creative client co-creation. I was so impressed at the final product they created, which was hugely comprehensive despite the large scope of the client being of the world's most far-reaching and best known consumer brands. I'm excited to see what we can create together in the future.
