Laboratory for the Philosophy and Psychology of Rationality and Decision

Within the Laboratory for the Philosophy and Psychology of Rationality and Decision (LPPRD), we study the mind through formal theories of representational content based on notions like questions and exact truth-making, and we conduct relevant experiments.


One of the main theoretical contributions of work in LPPRD has been the erotetic theory, according to which the aim of resolving questions is central to how the mind works. This line of inquiry has yielded a theory of our natural reasoning and decision-making capacity that accounts for empirically documented breakdowns like tempting fallacies and framing-effects, but that also explains the possibility of classical rationality. According to the erotetic theory, our minds naturally aim at answering questions as directly as possible, and if we are inquisitive enough in the process, we can get the kind of rationality required for science, philosophy, and classical economic agents as a special case.


Our work has led to the discovery of new framing effects in moral judgment, models of distraction and of delusional thinking, several new tempting reasoning fallacies, and a large-scale computer simulation of how fisherman decision-making interacts with marine ecology.
