As a psychologist, I often find myself noticing how the behavior of one person can affect the behavior of another. For example, over the past few weeks while driving to work in the morning, I have noticed that if I leave a space open at an intersection, the car in the lane next to me often will do the same. I tested my theory by sometimes blocking the intersection and sometimes leaving an opening and, without fail, the other driver followed suit. This isn’t ground-breaking science, but it got me thinking about how important is can be for each us to model prosocial behavior. I’m not talking about pay-it-forward, random acts of kindness gestures (though those certainly are nice, too) but rather modeling an awareness that there are other people around us to consider. Huffington Post recently published an article about the habits of considerate people which supposedly include, among other things, anticipating the needs of other people, having good manners, and being empathetic. These are not behaviors that necessarily take a lot of time or other resources; these are things we can be mindful of in daily activities. Perhaps letting someone in in traffic won’t solve all the world’s problems, but it does signal respect and may decrease another person’s frustration by a margin. What could be bad about that?
