Checking A Site's Corrections Policy
Launch library · evergreen read

A visible, easy to find corrections policy signals that a publication treats accuracy as an ongoing responsibility rather than a one time effort made only occasionally, willing to publicly acknowledge and fix genuine errors rather than quietly editing the record or simply ignoring them once already published for readers to see.
Sites without any visible corrections practice at all, or with a history of unexplained silent edits made to previously published claims, offer a considerably weaker foundation for trust, since there is no real accountability mechanism in place at all when something eventually turns out to be wrong or genuinely misleading.
Checking whether a specific past error was properly acknowledged, rather than judging the policy purely in the abstract, gives a much clearer sense of how a publication actually behaves in practice when its own reporting genuinely needs correcting after the fact, rather than merely in theory or empty promise.
