Kerem Oktar is a fifth-year PhD candidate in the Department of Psychology. His research aims to clarify the psychological and computational basis of disagreement – across scales, domains, and agents – from definition to intervention. He pursues these goals by (i) integrating insights from philosophy, psychology, and statistics to develop theories of how people respond to disagreement, (ii) testing these theories through behavioral experiments and computational models, and (iii) using these theories to design real-world interventions. He also studies decision-making; with particular interest in understanding people's preferences for relying on intuition vs. deliberation.
