What is our basis for taking a source as authoritative? Is it because we checked all of the person’s credentials? Is it because the source was fact-checked by Peter Canby’s team at the New Yorker? Or is it because the person has the most followers on social media and a “Verified” sticker next to their name? Authority is more mimetic than we like to believe. The fastest way to become an expert is to convince a few of the right people to call you an expert.
