MCCI: Unified Theory of Mental Holes--Causality--Choice Architecture

We construct a theory of ``mental holes'' verifiable under the triple norm of probability--utility--causality: given a rational baseline strategy and an embedding of observable architecture variables, we define the total deviation functional and its four-dimensional decomposition (bias, noise, causal mismatch, architecture sensitivity), provide identification criteria via backdoor/frontdoor/instrumental variables/discontinuity/difference-in-differences, and specify minimal experimental designs.
