Corrections
Manifold Rotor publishes corrections when substantiated errors affect the accuracy of our reporting. This page lists all corrections and updates to previously published stories.
Why We Publish Corrections
Accuracy is essential to the credibility of industry reporting. Manifold Rotor maintains a clear process for evaluating correction requests and publishing amendments when we discover or are shown factual errors in our published work. We distinguish between three categories: corrections for material factual errors, clarifications for ambiguous or incomplete phrasing that did not misstate facts, and retractions when an article must be removed from circulation because the central claim was false. We publish all three categories with the original publication date and the correction date so readers can assess the context.
When someone notifies us of a potential error, we evaluate it against the source documentation we used for the original article. If the error is substantiated—that is, if the published text contradicts the evidence we consulted—we determine its materiality. A minor spelling or typographical error does not appear on this page; factual errors about specifications, performance claims, industry standards, or business data do. We respond directly to the source of the correction request with our determination within two business days of receiving it, regardless of whether we publish a correction.
Correction or Clarification?
The distinction between a correction and a clarification matters for reader trust. When we published an article discussing ceramic coating hardness standards, the text stated that most consumer coatings test at 9H on the pencil hardness scale. A material scientist wrote to note that the article did not distinguish between claimed hardness and independently verified hardness, and that many products claiming 9H do not pass third-party testing to that standard. This was not a factual error—we did not claim that all 9H coatings were independently verified—but it was an incomplete statement that could mislead. We published a clarification alongside the original article noting that claimed specifications should be verified through independent testing before making purchasing decisions. The clarification does not change the original text but provides critical context.
A third case involved a press release we reported on from a trade association. The release claimed that a particular certification program covered 12 states; the association later issued an amended release correcting that to 8 states. Because we reported what the original press release stated, and the association itself issued the correction, we published an update noting the amendment and the date it was issued. This was neither our error nor a case requiring source criticism, but transparency demanded we note the change.
