The notion of generosity, and the ways in which we deal generously—or not—with our friends, family and communities—is the heart of the book, The Paradox of Generosity by Christian Smith and Hilary Davidson, which is based on empirical data collected during five years of research as part of the Science of Generosity Initiative. The research draws on a survey of 2,000 Americans, 60 in-depth interviews with individuals across 12 states, and more than 1,000 photographs and other visual materials. The conclusion Christian Smith, William R. Kenan Jr. Professor of Sociology, draws is that there’s a direct correlation with happiness and generosity. “The more generous Americans are, the more happiness, health and purpose in life they enjoy,” he says.
