Branden Bio and I recently published two papers at CogSci 2023 that focus on how people reason about mental states. The papers focus on two patterns we recently discovered: people’s online and offline knowledge interact, and they exhibit a systematic pattern of errors when reasoning about mental states.
About Me

I am a Senior Cognitive Scientist at the US Naval Research Laboratory in Washington, DC. I run the Reasoning Lab at NRL, where we study and build simulations of the mental processes that underlie everyday human reasoning.
