I’m a behavioral science researcher interested in knowledge representation, collective behavior, political judgment, and trust. I currently work for the Human Cooperation Lab at MIT, serving on a team led by Dave Rand, Gordon Pennycook, and Tom Costello that studies belief change due to interactions with large language models. Some of our work is here and here. I’m also a visiting scholar at Sloman Lab, where most recently I co-edited a special issue of Topics In Cognitive Science on collective cognition. Previously I studied individual and group behaviors associated with COVID-19 at The Policy Lab at Brown University (some of our work is published here, here, and here); trust in government at MIT GOV/LAB; and private sector climate change efforts at Harvard Business School. Way back when I worked on misinformation at Tufts University, led a review of political cognition for the European Commission’s Joint Research Centre, and managed the Arts & Mind Lab at Boston College.
