My working hypothesis is that people do this by combining general logic-like rules with sophisticated memories. My main approach is to develop mathematical theories for explaining activities like reasoning, categorization, and judgments of probability. I test these theories in my lab by examining people's ability to answer simple questions and name things.
Ongoing research examines the viability of formal, probabilistic models of causal and counterfactual inference and induction. One focus concerns people's sensitivity to the distinction between observation and action. Through action, people can run mini-experiments that might afford causal inference.
Sloman also studies several issues of categorization. First, do people have fixed categories of things in their heads or are categories completely determined by specific categorization tasks? For example, how well do the categories we use to name things correspond to the categories we use to induce the properties of things? Second, what are the "core" or central properties of an object and what makes them so important? The answer may have something to do with the causal activities that we engage in with the object.
Sloman also studies judgments of confidence and probability. The goal in this research is to understand the principles of coherence that underlie our beliefs. What makes evidence seem consistent with an hypothesis? In what sense and to what degree do our judgments have a rational basis?
