This report aims to integrate recent findings on the psychological and social underpinnings of behavior to make them available for more systematic use by both researchers and practitioners in development communities. The report draws on findings from many disciplines, including neuroscience, cognitive science, psychology, behavioral economics, sociology, political science, and anthropology. In ongoing research, these findings help explain decisions that individuals make in many aspects of development, including savings,
investment, energy consumption, health, and child rearing. The findings also enhance the understanding of how collective behaviors—such as widespread trust or widespread corruption—develop and become entrenched in a society. The findings apply not only to individuals in developing countries but also to development professionals, who are themselves prone
to error when decision-making contexts are complex.
