There are a lot of studies that confirm this finding. For example, these researchers discovered that people who had small talk with a barista in a cafe felt happier than
those who were in a rush and left right after they received their order. They explained that brief talks with strangers create feelings of belonging and that’s why they lead to an increase in happiness.
So, we believe that there is one conclusion we have to make now. It seems that we need to forget all of the biases we have toward other people. If you feel like having a chat with a stranger next to you — do it. And this will help both of you become a little bit happier.
