Jorge Hirsch, the h-index's inventor, used data-pattern forensics to help force the retraction of Ranga Dias's room-temperature superconductivity claim

In 2020 physicist Ranga Dias and collaborators reported room-temperature superconductivity in carbonaceous sulfur hydride under high pressure, a celebrated result published in Nature. Jorge E. Hirsch — the condensed-matter physicist who a generation earlier had invented the h-index and whose own field is superconductivity theory — became a leading critic. His argument was forensic rather than experimental: the published magnetic-susceptibility data fit an implausibly smooth curve for what should be noisy laboratory measurements, and he contended the team could not have produced those results "without using procedures that can only be characterised as data alteration and manipulation." Nature retracted the paper in September 2022.

The critique carried a social cost that outran its technical vindication: per the capture's account, Hirsch was temporarily banned from arXiv (Feb 2022) for the inflammatory tone of his accusations even as his substantive analysis held up [unverified — arXiv-ban date/duration rests on the capture's Tier-4 Wikipedia sourcing, not the Tier-2 reports; see the verification question].

This is the same "does the pattern of evidence make sense" instinct pointed in opposite directions — first to reward scientists with a citation number, then to unmask one by showing the numbers were too clean to be real. That "too clean to be real" test is not new to physics: it is the statistical descendant of a rule that runs from Fisher's 1936 verdict on Mendel back to Talmudic law, and it is the same principle by which the verbatim-but-non-independent Gersick quote gets graded down — developed in 2026-07-11-hop-suspicious-perfection. It is a data-forensics cousin of the "try to disprove, not prove" discipline in claim-ach-step-5-instructs-analysts-to-disprove-not-prove, and it belongs to the vault's small cluster on how scientific error does or does not get corrected — compare the propagation-failure case of claim-yellow-rain-bee-feces-refutation-never-formally-retracted, where a decisive refutation never reached the official record. Here, by contrast, the correction did land: the paper was withdrawn.
