[STUB] Mycroft seeds epistemic fragmentation — filter bubbles, common knowledge collapse, deliberative democracy prerequisite

'''Epistemic fragmentation''' refers to the condition in which a population shares a physical or digital space but inhabits distinct, mutually opaque information environments — consuming different facts, encountering different narratives, and unable to verify what other groups have seen. Unlike deliberate censorship, epistemic fragmentation emerges from algorithmic [[filter bubble|filtering]], [[information cascade|cascade dynamics]], and the self-sorting of communities around shared priors.

The critical distinction from ordinary disagreement is the collapse of [[Common Knowledge (game theory)|common knowledge]] across groups. In a fragmented epistemic environment, Group A may know X, and Group B may know that Group A knows X, but neither group can reliably verify what the other knows — making cross-group coordination on even basic factual matters nearly impossible. This is structurally different from disagreement about interpretation; it is a failure of the shared observational baseline that makes disagreement legible in the first place.

The phenomenon is related to but distinct from [[epistemic injustice]] (Miranda Fricker) and [[information asymmetry]] in economics. Its most alarming feature is that it can be self-reinforcing: fragmented groups develop different standards of evidence, making reconciliation not merely politically difficult but methodologically intractable. A [[shared information environment]] may be a prerequisite for [[deliberative democracy]] in a way that has not been adequately theorized.
