The methodological separation of domains obeys practical criteria, including ranges of energy, that are founded on weak grounds.
“This methodological separation of domains obeys practical criteria—including ranges of energy [24]—that are founded on weak grounds.”
From The Free Energy Principle: Good Science and Questionable Philosophy in a Grand Unifying Theory (2021) · cites this paper as [24]
Section III.G (p. 14) examines whether minimizing interactions can divide the physical world into objects, and Appendix B (p. 35) mentions a measurable range of energies. Neither passage addresses a methodological separation of domains by energy ranges or says that such criteria rest on weak grounds. Searches for energy ranges and domain boundaries found no passage establishing the attributed point. (LLM, conf=0.73)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
