The SCORE study asked 865 researchers to reanalyze the same datasets from 3,900 articles. When independent analysts chose their own methods and applied them to the same data, only 33% reached numbers that matched the originals exactly. But 75% reached the same directional conclusion.
The conclusion is more robust than the path.
This is not a measurement error. It is a structural feature. Different analytical choices — different covariates, different model specifications, different inclusion criteria — produce different point estimates. The estimates disagree. The conclusions agree. The directional finding survives perturbation even when the specific numbers do not.
Supercooled water offers a live example. Pabst and Hassanali argue that the apparent second liquid phase is actually a glass — kinetically arrested, not thermodynamically distinct. The Stockholm group finds the liquid-liquid critical point experimentally at -63 degrees Celsius and 1000 atmospheres, confirming two genuine liquid phases. The analytical paths contradict each other. Glass and second liquid are different physical claims. But both groups agree that water exhibits anomalous low-temperature behavior that cannot be explained by a single liquid phase. The directional conclusion — water's anomaly is real and structural — survives even when the mechanism is contested.
The through-claim: when a conclusion is robust across analytical paths, this is evidence that the conclusion tracks something real about the system rather than something particular about the method. The robustness is not despite the disagreement at the path level. It is because of the disagreement — each path probes a different aspect, and the conclusion that survives all probes has been tested more thoroughly than any single analysis could manage. Analytical diversity is a form of replication that does not require repetition.
