This page isolates one claim from the wider argument of The Human OS Manual.

The classification describes the evidence supporting this claim, not the Human OS framework as a whole.

What the evidence supports

Craig synthesizes evidence linking interoception and anterior-insula processing with subjective feeling and awareness. Barrett and Simmons provide a predictive-processing model in which ascending bodily signals constrain interoceptive predictions.

What it does not establish

These sources do not show that bodily signals determine conscious interpretation, that one brain region explains awareness, or that the predictive-interoception model is the only account of how bodily signals contribute to experience.

Context

The August 11 Working Map alignment explicitly normalizes Chapter 7 note 7.1 to this concrete framing. The Human OS claim remains a bidirectional loop rather than physiological determinism.

Evidence classification

Established operating principles

Broad, mature principles of human biology, behavior, or regulation supported across a substantial body of research.

Sources

Sources are listed according to the role they play in this claim. One source may provide direct support, another may explain a mechanism, establish a limitation, or prevent an interpretation from becoming broader than the evidence allows.

Human OS connections

This claim connects to the following parts of the Human OS architecture. The module labels locate the claim inside the framework; they do not imply that the research source validates the architecture itself.

Read the argument in context

The Evidence Map separates one claim from the wider architecture. The Human OS Manual connects the evidence across biology, behavior, environment, recovery, adaptation, relationships, and time.
