Blocking is an epistemic habit: once uncertainty is resolved, redundant cues are not sampled, so corroboration stops.

The claim

Under active inference, blocking is an epistemic habit: once a first cue resolves the uncertainty, actions toward a second cue carry no expected information gain about states, so the cue is not sampled and nothing about it is learned. Exploration built into expected free energy switches off exactly where corroboration would come from.

blocking under active inference can be construed as blocking exploratory behavior by removing the expected information gain or epistemic affordance of actions that do not resolve further uncertainty

T=3 L=75 above=Latent inhibition: a cue judged uninformative is ignored even after it becomes informative. below=Novelty-driven reading will show latent inhibition: sources judged uninformative early are never re-read. | Their simulation plus their reading; the animal attention evidence (Mackintosh line) is mixed, hence L75.
