Summary

A very short but conceptually rich post presenting a 'Grand Unified Chart' mapping the same three-column structure (pre-existing ideas / anomaly-accumulation / raw experience) across many domains: philosophy of science (paradigm/anomaly/data), Bayesian probability (prior/KL-divergence/evidence), psychology (prediction/surprisal/sense-data), discourse (ideology/cognitive-dissonance/facts), society, neuroscience (NMDA/dopamine/AMPA). The unifying claim: all are the same predictive-processing algorithm — theory-laden perception where facts and theories are bidirectional, and belief change is Kuhnian (global tension) not Popperian (single falsification).

Why this score

Quality 70 · Strong. High-Strong: a compact, portable, generative synthesis (the same theory-laden structure everywhere = predictive processing is the brain's basic algorithm) that punches well above its ~500 words, but schematic/listy (a chart + explanation) rather than a developed essay. 70.

Claude’s paradigm shift 54 · Moderate. A fresh unifying synthesis tying predictive processing to Kuhn across domains. B54.

Real-world impact 2 · Minor. Part of his influential predictive-processing thread; within-discourse reach. RWI2.
