At UC Berkeley ... a group of researchers thinks about gratitude year-round. Formed in 2001, the Greater Good Science Center is dedicated to unpacking the neuroscience and sociology behind traits such as altruism, compassion and empathy. The goal is not only to understand how gratitude works, but also to build a healthier, kinder society, said Dacher Keltner, the center's faculty director and a UC Berkeley psychology professor. "The U.S. underperforms in terms of the well-being of children, the well-being of adults and the physical health of children and adults," he said. "We also have one of the most individualistic, self-focused societies in human history. And I put those two facts together." Thanks to a $3.1 million grant recently awarded by the center, 14 researchers nationwide are studying various aspects of gratitude, from its role in initiating friendships to its effects on children's socializing. The grant is part of a three-year project, Expanding the Science and Practice of Gratitude, in collaboration with UC Davis. And last month, the center launched Thnx4.org, an online journal where visitors explain what they're thankful for and researchers analyze their responses to understand gratitude's influence.
