Fast-to-Slow Coupling

Canonical definition

The Fast-to-Slow Coupling is the formal specification of the handoff between the fast valuation layer (the three-node $M \to V \to S$ system operating on subsecond timescales) and the slow Bayesian layer (the Belief Register and Hypothesis Space operating on the timescale $\tauB$ ). The coupling map $\Phi:(Vt, St, bt, \mathcal{H})\to Et$ delivers the Decision Hub's Scalar to Conscious Cognition as Evidence, which is then lifted to a likelihood over the representable Hypothesis Space (Stage 1), used to update the Belief Register by Bayes' rule (Stage 2), and emitted back to the fast layer as a weighted Evidence proposition (Stage 3), where the emission strength is governed by the Evidence-Emission Coefficient $\omega(T{int})$ .

Explanation

The fast valuation loop runs your moment-to-moment reactions, and the slow Bayesian loop runs your settled Beliefs about why you want things. The Fast-to-Slow Coupling is the bridge between them. Your fast loop produces the Scalar, a feeling of wanting, which your conscious mind interprets by picking the most plausible explanation from its available Hypothesis set. That explanation becomes a piece of evidence that updates your Beliefs, and those updated Beliefs feed back into your fast loop by adjusting how much weight different motivational sources get. If your Hypothesis set does not include "this wanting might be mimetically driven," then the coupling systematically converts mimetic wanting into sincere false Beliefs about authentic motivation. This is the Confabulation Rationality Lemma in dynamical-systems form.
