Reasoning about inconsistency

To detect an inconsistency, people search for a possibility represented in a mental model, in which each proposition in a description is true. If they find such a possibility, the description is consistent; otherwise, it is inconsistent.

When an inconsistency arises from an incontrovertible fact, they retract any singularly dubious proposition or any proposition that is inconsistent with the fact; otherwise, they retract whichever proposition mismatches the fact. A mismatch can arise from a proposition that has only mental models that conflict with the fact or fail to represent it. Finally, individuals use their causal knowledge — in the form of models of possibilities — to create explanations of what led to the inconsistency.
