His current research focuses on promoting conflict intelligence and systemic wisdom as meta-competencies for navigating conflict constructively across all levels (from families to companies to communities to nations), which includes projects on adaptive negotiation and mediation; cross-cultural conflict adaptivity; optimality dynamics in conflict, justice and polarization; multicultural conflict; intractable conflict; and sustainable peace. 

 

In 2003, Dr. Coleman became the first recipient of the Early Career Award from the American Psychological Association (APA), Division 48: Society for the Study of Peace, Conflict, and Violence, and in 2015 was awarded the Morton Deutsch Conflict Resolution Award by APA and a Marie Curie Fellowship from The European Union.

Most recently he published a book with Columbia University Press on breaking through the intractable polarization plaguing the U.S. and other societies, titled, The Way Out: How to Overcome Toxic Polarization (2021). 

 

Dr. Coleman has also authored well over 100 articles and chapters, is a member of the United Nations Mediation Support Unit’s Academic Advisory Council, is a founding board member of the Gbowee Peace Foundation USA, and is a New York State certified mediator and experienced consultant. In 2017, he received the International Association of Conflict Management 2017 Best Conference Theoretical Paper Award for his article Conflict Intelligence and Systemic Wisdom: Meta-competencies for Engaging Difference in a Complex, Dynamic World, and in 2018 The Emerald Literati Award for the paper Adaptive mediation: An evidence-based contingency approach to mediating conflict. 

 

 

Dr. Coleman also founded and edits the MD-ICCCR Science-Practice Blog, the WKCR (89.9 FM) monthly radio program Peace and Conflict at Columbia: Conversations at the Leading Edge, and is a frequent blogger on Psychology Today and The Hill.

Rethinking Intractable Conflict

Intractable conflicts are those that are highly destructive and endure by perpetuating the very conditions of misery and hate that contributed to them in the first place. Certainly the most visible causes of such conflicts -- competition for scarce resources; ideological differences -- are important. But in a paper in American Psychologist, TC's Peter Coleman and colleagues argue for a paradigm shift in addressing such problems -- a dynamical systems approach that stresses the role of more basic dynamics and considers three strategies for changing systems of thoughts, beliefs and memories in enduring conflicts.
