OK, I have to correct myself. This was the page I was thinking of:
https://en.wikipedia.org/wiki/Christine_Peterson
https://en.wikipedia.org/wiki/Talk:Christine_Peterson
But taking a closer look at the various timestamps and edit history, it seems they did change "coined" to "suggested" once the evidence was presented.
Previously, I had seen this comment on the talk page, and assumed that it meant they refused to fix it:
> This is some useful research that could be reported in the media. That would be a source. As it is two reliable sources credit her. We cannot report your research even though it is convincing.
However, they seem to at least have changed the word "coined" immediately so as to remove the false statement.
Nevertheless, the mentality displayed in that comment on the Talk page is quite astounding: "Your research is convincing, but we have to ignore it."
