Professor Emeritus of Psychology, University of Washington

David P. Barash is professor emeritus of psychology at the University of Washington. He claims expertise in two areas: evolutionary biology (especially the behavior of people and animals) and peace studies (particularly with respect to nuclear weapons). Regarding the latter, he wrote the first comprehensive textbook of peace studies - Introduction to Peace Studies - as well as Peace and Conflict Studies, now in its 4h edition. His Stop Nuclear War! A Handbook, was a National Book Award nominee, as was The Caveman and the Bomb: evolution, human nature and nuclear war, which then-Chairman Gorbachev had translated into Russian for his personal use. He also wrote the first textbook on nuclear war - The Arms Race and Nuclear War - which was used at the country's war colleges, and his most recent book (coauthored with Judith Eve Lipton) is Strength Through Peace, an account of the highly successful demilitarization of Costa Rica.

He retired in 2017, after spending 43 years on the faculty of the University of Washington. He has written more than 250 peer reviewed technical articles, and has written, co-authored, or edited 40 books, and is a Fellow of the AAAS.

His most recent book is Threats: Intimidation and its Discontents (2020, Oxford University Press).
