Personal profile

Personal profile

My focus is on understanding and addressing the way certainty drives our tendency to judge harshly, demonize, and dismiss people who disagree. We often think of this as a problem of political polarization, a lack of civil discourse, or a lack of viewpoint diversity. Where those are actually the downstream effects of a fundamental problem in how we think. 

In addition to my role as an Associate Professor at the University of Illinois, I am the co-director of the Mill Institute at UATX. At the Mill Institute, we work with educators to create classroom spaces where they can challenge settled thinking and explore contentious topics together. 

My work includes:
