Kris N. Kirby

Kris N. Kirby is a Professor of Psychology at Williams College, where he is affiliated with the Cognitive Science Program. His research and teaching focus on decision-making processes, self-control mechanisms, and nonviolent behavior. Office locations include Wachenheim Science Center Room 325 and previously Bronfman Science Center.

Education:

• Ph.D. in Cognitive Psychology, Harvard University (1991)
• B.A. in Psychology and Philosophy, Marshall University (1985)

Professor Kirby's research centers on behavioral decision theory, particularly delay discounting (how people value future rewards), impulsivity, and self-control. His work bridges cognitive psychology and behavioral economics, examining applications in addiction, academic performance, and nonviolence. He has developed statistical tools like BootES for effect size analysis and explores Gandhi-inspired psychological frameworks for positive social change.

His publication record shows consistent focus on discounting mechanisms since the 1990s, with evolving applications from theoretical models to cross-cultural studies (including Tsimane' Amerindians) and clinical populations. Recent work integrates methodological innovation with psychological theory, demonstrating how discounting rates correlate with real-world outcomes like academic performance and substance abuse.
