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
Barlow, Wrosch, and McGrath meta-analyzed 31 samples. Goal disengagement showed a small association with greater quality of life, while goal reengagement showed a larger but still modest association; effects varied across well-being indicators and depression-risk context.
What it does not establish
The meta-analysis does not show that disengagement is always better than persistence, that every difficult goal should be abandoned, or that goal adjustment alone produces adaptation.
Context
The book uses goal adjustment as evidence that durable regulation can include changing the target rather than only exerting more effort.
Evidence classification
Strong human evidence
Supported by appropriate human studies, major reviews, trials, cohort research, or converging evidence. The strength of the category does not remove population, dose, timing, or context limitations.
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.
