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
Wood and Rünger review habits as context-linked automatic behaviors that develop through repetition and can operate efficiently outside deliberation.
What it does not establish
This does not mean that every repeated behavior is a habit, that habits are immutable, or that conscious intention is irrelevant.
Context
This source provides the habit-science bridge added to the final Chapter 3 note. It supports context-linked automaticity through repetition, not the Human OS friction model as a whole.
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.
