Eugene Garfield, who devised the Journal Impact Factor out of the citation
infrastructure he built at the Institute for Scientific Information, repeatedly
warned against the very use to which it was later put. In a 1998 letter to
*Der Unfallchirurg*, responding to a German trauma-surgery society's defense
of using the impact factor to judge "scientific achievement," he wrote: "The
source of much anxiety about Journal Impact Factors comes from their misuse
in evaluating individuals, e.g. during the Habilitation process... I have
always warned against this use." Seven years later he made the adjacent point
about misuse in general to the 2005 International Congress on Peer Review and
Biomedical Publication in Chicago, saying he "expected it to be used
constructively while recognizing that in the wrong hands it might be abused."
The metric was designed to describe the average citation rate of a *journal*,
not to rank a *person*.

This makes Garfield an early, self-implicating voice in the critique that
scientific institutions later formalized: his warning anticipates by decades the
first general recommendation of
[[claim-dora-2013-declaration-rejects-impact-factor-for-research-assessment]],
which tells institutions not to use journal metrics to assess an individual
scientist's contributions. It also frames the two documented gaming failures the
vault tracks — editor-side manipulation in
[[claim-wilhite-fong-2012-coercive-self-citation-common]] and the outright
purchase of a citation credential in
[[claim-saudi-universities-bought-clarivate-highly-cited-researcher-status]] — as
realizations of a misuse the inventor had already named. The recurring shape is
Goodhart's Law: a measure built to describe scholarly influence becomes an
evaluative target and stops measuring what it once did. Garfield did not just
assert the warning; he gave a specific technical reason for it, tying it to
[[claim-garfield-seglen-within-journal-variance-undermines-individual-use|wide citation variance among articles within a single journal]].
