BIO-ComplexityFebruary 8, 2026Michael Egnor, Robert J Marks
Integrated information theory (IIT) equates consciousness to integrated information, a concept that quantifies the interconnectedness of a system’s physical causal properties. However, IIT relies on a metric of complexity for integrated information—the phi (Φ) metric—that is both impractical to compute and insufficient to predict consciousness. Evaluating the Kullback-Leibler divergence for all...
