Overview

We investigate the cognitive roots of people's beliefs in order to understand the biases that prevent them from changing their minds. We approach these issues by conducting behavioral studies with children and adults, developing models of reasoning, surveying experts, and using data science techniques to analyze data from social media sites. 

 
 

The Cognitive science of Beliefs and Belief Revision

In the domains of medicine and morality, people are often deeply entrenched in their beliefs and resistant to any new information. These applied ethical problems motivate our research on belief revision: We examine the biases that prevent people from changing their minds. We aim to develop educational interventions to overcome these psychological obstacles and understand the beliefs that underlie people’s misconceptions.
