Could this be fixed by a change in Wikipedia policy? I’m thinking maybe a requirement that all cites be dated, and that a cite for a statement must predate the edit that added the statement.
I have two brothers who both enjoy inventing stuff to post on Wikipedia. One with a religious bent and the other on anything at all. Some of it gets removed such as his statement that Portland cement came from Portland Maine, but never form Portland Oregon. But he has done a dozen or more fantasy posts and says with a laugh that most of them are still there.
All cites are dated, both by when you find them and when they were published. And proving the the citation postdates the claim is a valid argument to say a cite is invalid.
Honestly, I’ve done this. About 8 years ago, maybe, now, I introduced a fact I invented in a wikipedia article, and now it seems to be fairly well entrenched on the internet, at least.
Why assume this is a phenomena unique to Wikipedia? Maybe we should instead assume it’s as common in all reference works as we’re discovering it is in Wikipedia.
I tried this 4 years ago when SDMB was playing Mornington Crescent, whimsically making a temporary change to the page of an obscure mathematician.
But within half an hour the change was flagged “citation needed”; 24 hours later it was gone. I’ve doctored the first URL in the above quote to point to the fake page:
Because Wikipedia is very different than printed reference works. Printed reference works, at least reputable ones, were more carefully researched, edited, and fact-checked than Wiki is. No doubt some made-up facts have gotten in to standard works, but there’s no reason to believe it would have been as common as it is in Wiki.
