Jehan Sparks, Ph.D.

Jehan is a behavioral scientist who studies judgment and decision making. She is currently a postdoctoral researcher at the University of Cologne, Germany. In Fall 2020, she will be joining UCLA Anderson as a postdoctoral researcher in the Behavioral Decision Making area, primarily working with Craig Fox on uncertainty and nudging healthy behaviors.


Jehan's primary line of research investigates how people get "stuck" in certain ways of thinking—like a negative (vs. positive) frame or a thought of what could have been worse (vs. better)—and the contextual factors that enable people to get unstuck and think more flexibly. She also studies whether people have insight into what they like and dislike in interpersonal relationships (e.g., romantic partners).

Jehan’s research uses online, laboratory, and field experiments to understand positive and negative thinking. This work intersects  with research on framing, counterfactual thinking, and ambivalence, and is intended to advance our understanding of positive and negative information while having implications for the types of real-world challenges people face every day as they think about who to vote for, who to date, and what to buy.
