Abstract: Behavioral science faces the formidable task of having to determine simultaneously what is deterministic (constant and same), while also determining what is probabilistic (uncertain and variable). Should scholars treat heterogeneity of behavior as a nuisance or as substance? These questions arise both between and within individuals. This presentation will introduce a mathematical modeling paradigm, and associated quantitative and computational analytics, that aim to provide novel, nuanced, and deep insights into the source and meaning of heterogeneity of behavior. Illustrative application areas span the entire discipline of Psychology, with an emphasis on decision research.

Bio: Michel Regenwetter obtained his Ph.D. in Mathematical Behavioral Sciences from the University of California at Irvine. His  primary goal is to model, measure, and predict preference and choice behavior when it is allowed to vary. Random utility models are designed as a modeling language to capture and quantify the ubiquitous variability in choice and preference behavior. Prof. Regenwetter's primary interests can be categorized as falling within three paradigms: probabilistic measurement, social choice, and preference evolution over time.
