Trained on Survivors - Reframing the Free Energy Principle as a Mechanics of Persistence

The Free Energy Principle (FEP) offers a mathematically rigorous framework for understanding self-maintaining systems. Its constructs—variational free energy, Markov blankets, active inference, attractor dynamics—provide genuine explanatory purchase on phenomena ranging from cellular homeostasis to cognitive inference. This paper does not dispute the formalism's internal consistency or empirical productivity. It contests the interpretive weight the formalism is asked to bear. The central argument is that FEP encodes survivorship bias as explanatory structure. The framework models systems that have already achieved persistence—that already occupy characteristic regions of state space, already maintain Markov blankets, already exhibit the self-maintaining dynamics that free energy minimization characterizes. Systems that fail to achieve such organization leave no trace in the formalism. The mathematics is trained on survivors; the rarity of survival is presupposed rather than explained. What appears as a theory of identity is, on examination, a theory of how already-constituted identities manage to persist. The paper develops this critique through engagement with FEP's core constructs: the hidden normativity in treating region occupancy as identity; the generality problem that prevents distinguishing thermostats from theorists; the treatment of resistance as structural feature rather than funded accomplishment; and the inference from Markov blanket possession to identity constitution. In each case, the framework is shown to presuppose what a theory of identity should explain. The alternative proposed—Identology—does not reject FEP but repositions it. FEP provides the mechanics of persistence conditional on identity; Identology specifies what counts as identity in the first place. The frameworks are complementary: one describes how survivors survive; the other explains what survival costs and why most trajectories never achieve it. The paper introduces no competing formalism. The error diagnosed is interpretive, not mathematical, and correcting it requires conceptual clarification rather than technical innovation. The goal is not to dismantle FEP but to specify its proper domain: a powerful mechanics of self-maintenance, not an ontology of identity.
