It seems like Wikipedia would be familiar with a lot of the same challenges that come with identifying fake news articles. Anyone more familiar than I am with Wikipedia care to comment?
Quoting Wikipedia policy itself:
>If Wikipedia had been available around the sixth century B.C., it would have reported the view that the Earth is flat as a fact and without qualification. And it would have reported the views of Eratosthenes (who correctly determined the earth's circumference in 240BC) either as controversial, or a fringe view. Similarly if available in Galileo's time, it would have reported the view that the sun goes round the earth as a fact, and if Galileo had been a Vicipaedia editor, his view would have been rejected as 'originale investigationis'.
