I recently wrote a feature for The Reasoner (edited by Hykel Hosni) that described the introductory chapter of The Handbook of Rationality (MIT Press). Both the feature (http://www.thereasoner.org/) and the entire volume of the handbook (https://mitpress.mit.edu/9780262045070/the-handbook-of-rationality/) are freely available online.

Phil Johnson-Laird, Ruth Byrne and I recently published a paper in PNAS on how people base their verifications of assertions (such as Tom visited Florida or Wyoming) on non-logical truth values: while binary logics stipulate truth values of true and false, and nothing more, humans comprehend truth values such as true and it couldn’t have… Continue reading
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.

It may require some effortful thinking and some background knowledge to construct a plausible explanation from scratch, so you need a good reason to do so. One of the most important reasons for why people generate explanations is to resolve inconsistencies. Previous research showed as much: when faced with some inconsistent causal information, reasoners spontaneously… Continue reading
Phil Johnson-Laird and I have a new paper the describes a theory and computational model of how people reason about properties. The theory holds that people construct small-scale mental simulations of entities linked to their properties, and that the more mental simulations they build, the harder a problem will be. A computer model, mReasoner, simulates… Continue reading
Hillary Harner and I have a new theoretical paper out in Cognitive Science on the processes and mental representations people rely on to reason about desire. The paper shows that people think of desires as “counterfactive” — A wants X implies that X isn’t the case by default. It also shows that people separate desires… Continue reading
Phil Johnson-Laird, along with his collaborators Monica Bucciarelli, Robert Mackiewicz, and myself, published a paper in Psychonomic Bulletin & Review that reviewed research into how humans consciously reason about recursive operations. Though the term “recursion” is often used by computer scientists to describe specific types of programs, people without any background or training in computer science can… Continue reading
Hillary Harner and Laura Kelly successfully completed their NRC Postdoctoral Fellowships this Fall — congratulations to them both! Throughout their years at NRL, Laura and Hillary made some important discoveries into how people reason about durations and how they reason about desire. Laura Kelly‘s work in the Reasoning Lab focused on how people reason about… Continue reading
I’m extremely excited that Branden Bio began his postdoc at NRL this week! Dr. Bio is coming from Princeton’s Psychology Department, where he worked on studying attention, awareness, and its underlying neural mechanisms. His recent work focuses on how people attribute conscious states to others. He’s published papers in PNAS, eLife, and Cerebral Cortex. At… Continue reading
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.
