Persistence Bias

Persistence bias is the statistical asymmetry in transition probabilities by which a system, under fixed dynamics, constraints, and noise statistics, is more likely to remain within or return to previously occupied regions of effective state space than to transition into radically reconfigured regions.

It is not a force. It is an emergent bias in the stochastic flow of trajectories produced by barriers, constrained reachability, and the combinatorial difficulty of dismantling persistent distinctions.

Persistence bias is scale-relative: what counts as “the same region” depends on coarse graining and the effective description used.

Through this role, persistence bias:
