I’m not very familiar with how Wikipedia vets the sources in the references/external links. I was wondering whether there are manual or automated checks for cyclic sources, for example a Wikipedia page cites a source for something, but such source after a few rounds of citing would go back to the same Wikipedia page.
- Does that happen with Wikipedia?
- Does it matter? I presume that would invalidate the source?
- How do they make sure it does not happen? Is there an automated check or something?
Wikipedia does not check if the sources themselves cite Wikipedia. I mean they can, but they rarely do.
This has led to situations where a falsehood keeps getting added because it has a “reliable source” and editors are too lazy to question it.
