Talking with Strangers

 A hefty body of research has found that an overwhelmingly strong predictor of happiness and well-being is the quality of a person’s social relationships. But most of those studies have looked at only close ties: family, friends, co-workers. In the past decade and a half, professors have begun to wonder if interacting with strangers could be good for us too: not as a replacement for close relationships, but as a complement to them. The results of that research have been striking. Again and again, studies have shown that talking with strangers can make us happier, more connected to our communities, mentally sharper, healthier, less lonely, and more trustful and optimistic.
