Cognitive Psychology and Repeated Falsehoods

Disinfo Discussions: Dr. Polage and Dr. Hemmatian

Two experts in the field of cognitive science bring an understanding to how the brain responds to false information online. Dr. Danielle Polage is a cognitive psychologist and professor at Central Washington University. She’s studied the impacts of false information in digital environments, and the effects that exposure to repeated lying can have on an individual’s belief patterns. Dr. Babak Hemmatian has a Ph.D. in cognitive science and a Masters in computer science from Brown University. He studies how social narratives form and are negotiated using computational methods and behavioral experiments. His research dives into how people communicate and find consensus online.

This session is part of a series of expert briefings hosted in tandem with our Commission on Information Disorder to help make sense of the various facets of the information crisis. “Disinfo Discussions” is designed as a resource for the commissioners as well as the broader public.
