Conjecture
Free energy minimisation on its own does not produce the classic results of associative learning: in active inference models of conditioning the fit comes from structure added to the model and parameters set after the fact, so the fit does not test the principle. In an active inference model of Pavlovian conditioning, adding a redundant second cue does not by itself reproduce blocking, because learning the second cue still raises accuracy and so lowers free energy; blocking appears only once an attention action is added. The same model then explains both blocking and the frequent failures to replicate it by moving the balance of cue novelty against reward value, and a model that predicts an effect and its absence, depending on parameters chosen afterwards, cannot be tested by that effect. Its integration of Rescorla-Wagner, Mackintosh and Pearce-Hall rests on a few simulated phenomena (single-cue learning, blocking, latent inhibition, overshadowing) with no fit to animal data and no new prediction tested. Its reading of reward prediction error as a by-product of free energy minimisation rather than the driver of learning is undone by its own alternative learning rule, which weights updates by the free energy of the reward observation and so brings a prediction-error driver back. Integrating existing models without settling a dispute between them redescribes; it does not explain.
