Definition

A generative hierarchy is the predictive-processing organization in which higher levels encode more abstract, temporally extended or context-rich regularities and lower levels encode more immediate sensory expectations. RB2 describes predictions descending and residual errors ascending to revise the model. The proposal keeps this explanatory architecture distinct from a hierarchy of personal worth, a literal inner observer or a complete account of embodied life.

Explanation

The defining passage relates levels by their different scope and temporal grain. Lower-level mismatches can alter higher expectations, while successful predictions require less revision. Hierarchy therefore concerns interacting constraints and correction rather than a sovereign top layer that already knows every detail or a one-way command chain immune to input.

Walking in a familiar home and hearing speech in noise illustrate expectations making perception economical while unexpected events remain disruptive. Such examples are authorial explanations of the theory, not independent measurements of one universal anatomical circuit. The world’s resistance remains necessary to surprise, learning and reality-testing.

RB2 frames predictive processing as action-oriented and embodied, yet explicitly denies that it settles the entire biology of anticipation or collapses phenomenology into error minimization. The proposed entry accordingly retains a computational architecture at its stated explanatory level, without making all self-maintenance, experience or symbolic meaning identical to this hierarchy.
