Measuring Consciousness Like Temperature: The CI Formula Explained
The Consciousness Index gives every physical system a definite number. Physically grounded, calibrated on 100 species, every result traceable to 13 independently assigned biological parameters.
Temperature was once a qualitative concept. Then the thermometer made it measurable - and thermodynamics became possible. Consciousness is at the same pre-measurement stage: real, recognised, discussed, but not quantified. BFUT Paper 21 provides the measurement. The Consciousness Index (CI) gives every physical system a definite scalar number.
The CI Formula
The base CI₀ captures structural capacity: CI₀ = CI_floor + C × Ω(V) × (1+0.38A) × N^1.3 × K^1.2 C = 182.5283 anchors the human average CI₀ = 100. Ω(V) is the sensory bandwidth across five channels. A is the adaptive capacity. N^1.3 and K^1.2 are processing unit count and connectivity - super-linear because complexity scales non-linearly with neural count and connection density. CI_floor = 1.0 ensures no system has zero consciousness. The effective CI applies the survival factor S: CI = max(CI_floor, CI₀ × S) S = 0.35(1−P) + 0.25(1−E) + 0.20(1−D) + 0.20·I S captures structural fitness: P (predation vulnerability), E (environmental fragility), D (disease susceptibility), I (integration efficiency). S ranges from 0 to 1. Human S = 1.0 - uniquely maximum across all 100 species in the dataset.
The Five Measurement Channels
Ω(V) is measured across five channels corresponding to the five sensing modalities of Paper 20: sensory bandwidth (range and resolution of input sensing), environmental interaction (active modification of environment), social communication (electromagnetic-channel information exchange with conspecifics), manipulation ability (controlled physical action), and internal sensing (proprioception, interoception, self-model depth).
Dataset Integrity
The 100-species dataset contains 30 consistency-check species (N solved from target CI to verify biological plausibility) and 70 genuine out-of-sample predictions (all parameters assigned independently from biological literature, no adjustment to produce a desired CI). The 70 predictions constitute the scientific content. The formula is transparent: every result traces to 13 independently assigned biological parameters, all documented and checkable.
