Belief storage is often modeled as having the structure of a single, unified web. This view of belief is attractive and widely assumed because it appears to provide an explanation of the flexibility of cognition and the complicated dynamics of belief revision. However, when one scrutinizes human cognition, one finds strong evidence against the web, and suggestive of a fragmented model of belief storage. Using the best available evidence from cognitive science, I develop this fragmented model into a nascent theory of the cognitive architecture of belief storage.
