Christopher Peterson

Christopher Peterson is best known for co-authoring the VIA (Values in Action) Classification of Character Strengths and Virtues alongside Martin Seligman. This comprehensive framework identified and categorized 24 universally valued character strengths, such as bravery, kindness, and curiosity. The VIA Classification remains the foundational manual for the scientific study of positive human traits.

Christopher Peterson spent his academic career as a highly respected professor of psychology at the University of Michigan. He was based in Ann Arbor, where he conducted his research on optimism, character, and well-being. At the university, he was deeply beloved by students and frequently won major teaching awards for his engaging lectures.

Published in 2006, this textbook was one of the first comprehensive academic summaries of the emerging positive psychology movement. It synthesizes research on what makes life most worth living, covering topics like positive emotions, grit, wisdom, and hope. It remains a core text in university courses seeking to understand human flourishing rather than just mental illness.

Before pivoting strictly to positive psychology, Peterson conducted pioneering research on the physical health impacts of optimism and pessimism. He specifically studied the trait of explanatory style, finding correlations between a pessimistic outlook in youth and poorer cardiovascular health decades later. This early work helped scientifically establish the mind-body connection, proving that psychological traits have long-term physiological impacts.
