 ToM is a particular kind of theory: it is assumed to have a distinctive sort of content. A ToM operates with mental state concepts that feature in theoretical postulates that comprise the core general principles of a theory of everyday psychology. The content of the ToM that normally developing humans use is, for TTists, what enables most of us to navigate our everyday social world fluidly and with ease. TT holds that we succeed in understanding ourselves and others if we manage to infer the mental states responsible for particular actions correctly by applying a ToM, thereby bringing the laws of everyday psychology to bear on particular cases. As such, TTists hold that, for most of us, the heavy lifting in daily social cognition is done by our acquaintance with, and use of, laws of a folk ToM.
