Detailed Biographical note

I am Professor of Psychology Emeritus at the University of Massachusetts, Amherst, and Founding Director of its Ph.D. concentration in the Psychology of Peace and Violence. I was born in Hungary, where as a young child I lived through Nazism, and then communism. I escaped from there when I was 18 years old after the Hungarian revolution of 1956 was defeated, lived in Vienna for two years, and then came to the U.S. I finished my undergraduate education at the University of Minnesota and received my Ph.D. at Stanford. I taught at Harvard and was visiting professor at Stanford, the University of Hawaii and the London School of Economic and Political Science.

I have studied the influences that lead to caring, helpful, altruistic behavior and moral courage in children and adults, and their development in children. Having studied both
active bystandership,” and passivity in the face of people in need, I turned to a focus on perpetration. I studied the social conditions, culture, psychology of individuals and groups, and social processes that lead to mass violence, especially genocide and mass killing, but also violent conflict, terrorism and torture. I studied how such violence progressively evolves, and the role of passive bystanders in allowing the unfolding of violence. Increasingly I focused on understanding how violence between groups can be prevented, as well as how hostile groups can reconcile, especially in post-conflict settings after violence between them. I also studied and worked on facilitating positive group relations. I have been concerned with how active bystandership in the service of prevention of harmful behavior and reconciliation can be promoted. 

My books include the two volume Positive social behavior and morality (Volume 1, Social and Personal influence, 1978; Volume 2, Socialization and development, 1979); The roots of evil: The origins of genocide and other group violence (1989); The psychology of good and evil: Why children, adults and groups help and harm others (2003); Overcoming evil: Genocide, violent conflict and terrorism (2011); and edited or co edited several books (see Vita), including Patriotism in the lives of individuals and nations (1997). In 2015 I published The roots of goodness: Inclusive caring, moral courage, altruism born of suffering, active bystandership and heroism.  New York: Oxford University Press. I have also written many articles and many books chapters for edited books, and blogs on several blog sites, including Psychology Today and Huffington Post.

I have worked on varied projects in field settings, their approach primarily based on my research (See Staub, 2018, in Vita).  I developed a training program for the State of California after the Rodney King incident to reduce the use of unnecessary force by police, by training police officers to be active bystanders who prevent or stop unnecessary harmful behavior by fellow officers. Since 2015 I have been collaborating in developing and using a version of this program by the New Orleans police department. It has very positive effects, and media attention and articles about it in police Journals led to conferences in New Orleans in 2018 and 2019 with leaders of police departments around the country who expressed interest in introducing it in their departments. Other projects included teacher training to create classrooms that help children become caring and non-violent; a project in Amsterdam to improve Dutch-Muslim relations after significant violence there; a project in New Orleans to promote healing and reconciliation in the wake of Katrina; and a Training Active Bystanders project in Western Massachusetts to train students in schools in active bystandership in the face of harmful behavior by their peers towards other peers. A curriculum of this training is available on this website (

Starting in 1999 I have conducted workshops/trainings in Rwanda, together with Laurie Anne Pearlman and both U.S. and Rwandan assistants, for the staff of organizations that work in the community, with national leaders, with people in the media, and others.  In collaboration with Radio LaBenevolencija of Amsterdam, using the approach we had developed for our trainings, we created a variety of educational radio programs, both informational programs and radio dramas. An educational radio drama which began to broadcast in 2004 in Rwanda is still ongoing, as is a radio drama in Burundi that began to broadcast in 2006. Another of our radio dramas, in the Congo (DRC) stopped broadcasting in 2016 after 11 years. The aim of this work has been to promote healing, reconciliation, and help prevent new violence and/or stop ongoing violence, and help people impacted by violence lead better lives. This work has been supported by a variety of funders, to Laurie Pearlman and me, and to Radio LaBenevolencija. In 2007 the Rwandan radio projects won the Human Rights & Accountability award that was launched by the UN for the 60th anniversary of the Declaration of Human Rights.

I also served as an expert witness in violence related cases, for example, at the Abu Ghraib trials. I lectured widely on topics related to my work in academic, public, and government settings in the U.S. and other countries (see Vita on the website).
