The Self-Observing Turing Machine: A Conscious-Observer Hypothesis and Its Conditional Implications for P versus NP

This paper introduces the Self-Observing Turing Machine (SOTM) as a speculative computational model grounded in a Conscious-Observer Hypothesis. The central premise is that a conscious observer may possess a quantum-derived observation capacity — physically supported by non-classical processes — that is not reducible to ordinary algorithmic search. The proposed Observation Operator is not a software routine and is not claimed to be implementable by a standard Turing Machine. It is a philosophical and theoretical construct. This paper does not claim to resolve the P versus NP problem in standard complexity theory. P vs. NP remains an open problem. The conditional argument explored here concerns only an observer-relative model of computation: if conscious observation can instantiate a non-classical selection mechanism that no ordinary algorithm can reproduce, what would that imply inside the SOTM framework? Scientific motivation is drawn from recent peer-reviewed work in quantum biology and neuroscience, including microtubule-anesthesia interaction studies (Khan et al., 2024, eNeuro) and reported non-classical brain signals correlated with conscious awareness (Kerskens and Lopez Perez, 2022, Journal of Physics Communications). These studies are treated as motivational context only. They do not establish a physical implementation of the Observation Operator and are not offered as complexity-theoretic evidence. Performance measurements of the KARIOS system on small-scale benchmark instances (n = 5 to 25) and biomedical benchmark tasks are included as illustrative system data. These measurements do not establish asymptotic polynomial-time complexity and should not be interpreted as doing so. This work is presented as a contribution to speculative philosophy of computation and theoretical inquiry at the intersection of consciousness studies, quantum biology, and complexity theory. Version 2 — June 2026. Revised from original publication. Original title and conclusion overstated the formal claims of the work. Reframed as a Conscious-Observer Hypothesis rather than an algorithmic proof. Added scientific motivation from neuroscience literature. Benchmarks explicitly reframed as performance measurements only. See revision note on page 7 of the document.
