Melvin J. Lerner is Distinguished Professor Emeritus of the Department of Psychology of the University of Waterloo, where he founded the Division of Social Psychology. The majority of his research efforts focus on the theme of justice in people's lives. Much of that research has been summarized in several volumes, beginning with Belief in a Just World: A Fundamental Delusion (1980), which was awarded the Quinquenual Prize from the Society for the Scientific Study of Religion, and continuing in several co-edited volumes: with S. Lerner, The Justice Motive in Social Behavior: Adapting to Times of Scarcity and Change (1981); with Gerold Mikula, Entitlement and the Affectional Bond (1994); with Leo Montada, Responses to Victimizations and Belief in a Just World (1998); and Current Societal Concerns about Justice (1996). In addition, Lerner is the founding editor of the journal Social Justice Research and was the co-recipient of a Max-Planck-Forschungspreis and a Lifetime Achievement Award from the International Society for Justice Research. Susan Clayton is Whitmore-Williams Professor of Psychology and Chair of Environmental Studies at the College of Wooster. She has published extensively on topics related to justice as well as the natural environment. With Faye Crosby, she wrote Justice, Gender, and Affirmative Action (1992), which received an award from the Gustavus Myers Center for the Study of Human Rights in the United States, and with Susan Opotow, she co-edited a volume of the Journal of Social Issues on 'Green Justice' as well as Identity and the Natural Environment (2003). She is also the co-author (with Gene Myers) of Conservation Psychology: Understanding and Promoting Human Care for Nature (2009). Clayton is a Fellow of the American Psychological Association and has served as president of the Society for Population and Environmental Psychology.

“Given the broad acceptance of capitalist philosophy in most of the developed and developing world, one could expect that self-interest motives would be used to explain all sorts of human interactions with others. Further, it could be expected that such explanations would be readily accepted. Are there no situations where humans act to provide or restore justice to others without benefit to themselves? Lerner and Clayton’s work emphatically says ‘yes, there certainly are many such situations.’ The authors apply careful scientific analyses to studies purporting to support the self-interest explanation and dismantle them with surgical precision. They show that people's actions can stem from justice-seeking motives and not solely from strict self-interest.” – Selwyn Becker, Professor Emeritus of Psychology, Booth School of Business
