Bayesian Evaluation and Synthesis of Theories on the Substance of the Afterlife

Abstract: This article evaluates leading hypotheses about the substrate of a putative afterlife—including subtle-energy/vital-force models, quantum information and zero-point field models, higher-dimensional ‘hyperphysical’ accounts, and consciousness-primary (idealist/simulation) frameworks—using a neutral-prior Bayesian lens. We assess how well each predicts empirical survival-of-consciousness evidence (e.g., veridical NDEs, mediumship, psi effects) and recent unification proposals that center information geometry and nonlocal fields. The posterior favors an information-centric hybrid: a consciousness-infused informational field (or ‘mindstuff’) that can exist independently of biological matter yet couple to brains during life. We synthesize these perspectives into a paraphysical continuum—structured, nonlocal, and responsive to intention—offering testable directions for instrumental transcommunication and signal-complexity assays.
