 It is argued that as a result of the feature, Hypothesis theory can account for instances of poor learning that occur in some cases even when the statistical associational strength is high ().The process by which a subject is proposed to go about forming such rules or hypothesis has been the topic of formal probabilistic modeling, a discussion of which can be found in the references.A conceptual framework for formal probabilistic modeling of hypotheses in cognitive research has been given by Rudolf Groner

Hypothesis theory has fallen out of favor (along with many other rule-based models) in the wake of prototype and exemplar theories, both of which employ a notion of graded similarity rather than crisp set membership.
