Experts

[Edwardo Piet]

My general rule:

Trust an expert if there’s a consensus among experts in his field, and if that field is considered overwhelmingly trustworthy by other relevant fields.

^ This pretty much.

I don't trust people on the fringe until they're accepted.

I mean, sure, people like Einstein will come along who are laughed at but they are eventually taken seriously.... and for every Einstein there's 10,000 nutjobs.
