In this manuscript we study individual variation in the interpretation of conditionals by establishing individual profiles of the participants based on their behavioral respon- ses and reflective attitudes. To investigate the participants’ reflective attitudes we introduce a new experimental paradigm called the Scorekeeping Task, and a Bayesian mixture model tailored to analyze the data. The goal is thereby to identify the participants who follow the Suppositional Theory of condi- tionals and Inferentialism and to investigate their performance on the uncertain and-to-if inference task.
