“…The model theory is based on a fundamental principle of parsimony according to which individuals tend to construct only a single, simple, and typical model (Goodwin & JohnsonLaird, 2005;Johnson-Laird, 2006).

Depending on this initial model, the task of evaluating consistency can be easy or hard.…”
