The five-second checklist

Who hosts this page, and do they vet what goes on it?
Who wrote it, and who vouches for them?
Is there a DOI or a journal page you can check yourself?
Does anyone else cite or replicate it?
Has it been corrected or retracted?

No label is magic. Peer review catches errors but does not remove them, and even a good source can be quoted out of context. Read the actual claim, then check who is making it.

A note on these notes: the history blurbs lean on Wikipedia and a few primary pages. Wikipedia is a good map, not the territory, so follow its citations to the original documents before you rely on a detail.
