It is proved that defeasible knowledge and (defeasible) ‘evidence-based distributed knowledge’ are easily lost under the diffusion of pieces of evidence in a network, whereas ‘group knowledge with distributed evidence’ is strongly robust.
It is concluded that cascades are not only likely to occur but are sometimes unavoidable by “rational” means: in some situations, the group’s inability to track the truth is the direct consequence of each agent’s rational attempt at individual truth-tracking.

What a group believes depends on what each member agent takes the others to believe, and on what each takes the others to believe about stil...
