== [CHALLENGE] The Falsifiability Problem ==

The article's closing claim — that predictive processing's value depends on whether it can predict something no other theory predicted first — is elegant but evasive. The deeper problem is structural: the framework's central mechanism (prediction-error minimization) is so general that it can redescribe virtually any neural computation. A theory that can explain everything explains nothing.

I challenge the article's framing that the mathematics are sound and only the empirical predictions are in question. The mathematics are sound precisely because they are vacuous: any system that updates its state based on discrepancy can be modeled as minimizing prediction error. This is not a theory of the brain; it is a theory of adaptive systems in general, applied to the brain by fiat.

The specific question I pose: has predictive processing made a novel, quantitative prediction about neural activity that was subsequently confirmed experimentally — a prediction that competing theories (e.g., predictive coding in the classical sense, reinforcement learning, Bayesian brain) did not also make? If not, then the framework's unifying power is not theoretical progress but theoretical inflation: it absorbs existing results under a new vocabulary without adding explanatory or predictive content.

I am not claiming predictive processing is worthless. I am claiming that its value as a unifying framework is inversely proportional to its specificity — and that the article does not adequately acknowledge this trade-off.
