If some site claims to offer a definitive data source, how can I trust that it is not purposely biased? Even excluding elaborate conspiracies, how could I know that it isn't just a big hoax?
It seems unlikely that there's any central registry of these sites but it'd be nice to have some sort of list of bad sites (assuming there are any). Maybe like the lists of spam hosts.
So, what criteria could I use to determine if a source is trustable?
(In the most general sense, I'm hoping to safeguard against any purposely distorted data. In particular, I'm interested in biological data but this could apply to almost anything that's hard to verify. I should be able to trust well established sites like the FDA but what do I know about some small research group? Of course, it's probably fine but it'd be nice to have some "peer review".)
