In the Footsteps of Kurt Lewin: Practical Theorizing, Action Research, and the Psychology of Social Action

How and why do people become actively involved in doing good for others and for society by taking action to respond to social problems? Such involvement can take the form of participation in volunteerism and philanthropy, community groups and neighborhood organizations, and social activism and political movements. To understand the dynamics of these processes of social action, I draw on coordinated programs of basic and applied research, conducted in field and laboratory settings, to illustrate the complex interplay between features of persons and properties of their environments in determining why some individuals become involved in social action, what sustains their involvement over time, and the consequences of such action for individuals and for society. Then, building on the messages of these programs of research, and the theoretical perspectives guiding them, I consider implications for social policy issues of relevance to individuals, groups, and society as well as the ways in which the social sciences can contribute to the effective functioning of society and the well‐being of its citizens.
