Rapid book catalog
A fast, inspectable first pass—not an expert verdict on an entire book.
Each book gets exactly three central factual or causal claims. A rough AI assessment assigns 100% for supported, 75% for mostly supported, 50% for mixed, or 25% for weak. The displayed score is their average, rounded to the nearest whole number.
The selection of those three claims is itself a judgment. A different defensible selection could change the score, and this rapid layer does not confirm the exact wording against a specific edition.

The automated audit followed every unique citation. It tests whether a URL responds; it cannot tell whether the source is strong enough for the claim.
Publisher anti-bot responses are deliberately separate from confirmed broken links. Timeouts and network failures remain unresolved rather than being called good or bad. Snapshot 2026-09-01 using http-head-get/0.1.0.
Fifteen books were sampled across five domains to look for obviously implausible score behavior. This is a rough audit, not an independent fact-check.
Guns, Germs, and Steel 67 · Sapiens 67 · The Dawn of Everything 67
All three land at 67 because the selected claims mix durable broad patterns with disputed universal or deterministic framing. Passage-level selection review remains the main calibration risk.
The Gene 92 · The Emperor of All Maladies 92 · The Structure of Scientific Revolutions 67
Evidence-rich scientific histories score highly; Kuhn lands lower because two selected universal claims remain contested. The spread is directionally plausible, not proof of accuracy.
The Great Influenza 83 · The Hot Zone 75 · Midnight in Chernobyl 100
Documentary histories score strongly while The Hot Zone loses credit for sensationalized transmission and symptom framing.
The Innovators 83 · The Box 92 · Bad Blood 100
Specific institutional and fraud records score higher than sweeping innovation narratives. This domain may be easier to source than ancient macrohistory.
The Warmth of Other Suns 100 · The Better Angels of Our Nature 58 · Why Nations Fail 67
Narrow documentary claims score higher than global decline or single-cause institutional theories. Selection and causal-scope judgments deserve expert review.
