>You trust a photo from a photojournalist. You don't trust a photo from some rando in your social feed.

The problem is, this isn't highly true.

Sometimes we don't trust photos from some journalists, not necessarily because we think it is dramatically edited, but we know even professionals have been caught mildly editing, either in-camera or with tools afterward.

Conversely - sure, we don't trust when we see a photo from a rando slandering a politician, unless we want to believe it. At the same time, we mostly believe a rando photo of a fireman rescuing a cat. The latter is less likely to be fake, and if it is, the consequences of believing it are less severe.

Trust heuristics are complex and highly psychological.
