My research interests center on the origin of mental representations. How do we humans come to understand the world and its workings, and our place in it? I divide this issue into two related parts. The first is causal induction. How do people come to know that one thing causes another? Some sequences of events are merely associated; others are causal. How do people tell such sequences apart? And what comes to be represented as “things” that cause other “things”? Thus, the second issue is category formation. Objects and events in the world can be partitioned in infinitely many ways (e.g., objects that move in the wind, three-legged objects, sequences of air compression and rarifaction that bring pleasure, repeated actions, etc). Out of the infinitely many logically possible categories, only a minuscule fraction are commonly used (e.g., grass, polar bear, kite, melody, phone, smoking). Why do people have the folk categories that they have, but not the countless others that they don’t? The two issues are intertwined in that folk empirical categories are all causal (have consequences for us) in some way.

I primarily develop theories from a computational perspective and evaluate their implications, in particular, those for rationality. These include rational causal statistics and rational actions to address existential threats to humanity. I evaluate the theories and implications by conducting cognitive experiments on normal humans, mostly adults but preschoolers as well. I also consider other approaches to the underlying issues, including philosophical, artificial intelligence, anthropological, comparative, and neuroscience approaches.
