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.
