Paper VI of the Complexity Binding Theory (CBT) program — the Minimum Information Cost Principle, or MICP — predicts that the decoherence time of a quantum superposition with outcome distribution p scales linearly with its Shannon entropy: τₘeas (p) = H (p) / (γ₀ ln 2). Independently, and for seventy years, experimental psychology has documented the Hick–Hyman law for human choice reaction time: RT (p) = a + b·H (p). This note observes that these two laws share a common derivation from Shannon's source coding theorem: any system that acquires information at a bounded rate R and resolves outcomes drawn from distribution p has resolution time of at least H (p) /R. The functional form τ ∝ H (p) is therefore universal; only the rate R differs between domains, by approximately eight orders of magnitude. The identification does not imply that quantum measurement and neural categorization share a mechanism. It does, however, yield a first-principles upper bound on the information acquisition rate of any physical system at temperature T: Rₘax (T) = kT / (ℏ ln 2). The human conscious mind operates approximately thirteen orders of magnitude below this bound, a statement about the inefficiency of biological computation rather than about consciousness. If MICP's T₂ (p) ∝ H (p) prediction is confirmed experimentally on a qubit platform operating near the Landauer floor, the confirmation would place quantum measurement and human choice reaction on the same formal curve with vastly different slopes.
