cognitive sciences to explain a wide variety of phenomena and experimen-
tal results: memory retrieval through the spread of activation, mapping two
knowledge structures via structural alignment, instantiation of an abstraction,
implicit quantitative learning and so on. All of these processes have been sim-

bine these processes in a way that explains how a change in core beliefs can
come about in the face of cognitive resistance to contradictory information.
RELATIONS TO OTHER THEORIES
The Resubsumption Theory implies that terms like “belief revision,” “concep-
tual change” and “theory change” are misnomers: It is not so much a belief,
