• Description

Throughout history and around the world, religious leaders and philosophers have extolled

the virtue of gratitude. Some have even described gratitude as "social glue" that fortifies

relationships—between friends, family, and romantic partners—and serves as the

backbone of human society.

But what exactly is gratitude? Where does it come from? Why do some people seem to be

naturally more grateful than others? And are there ways we can foster more feelings and

expressions of gratitude?

Over the past two decades scientists have made great strides toward understanding the

biological roots of gratitude, the various benefits that accompany gratitude, and the ways

that people can cultivate feelings of gratitude in their day-to-day lives. The studies

comprising this science of gratitude are the subject of this paper.
