A lot of studies have been performed on the nature of fake news and it's spread on social media sites:

A problem I have with a lot of these studies is how they seem to ignore the structure of a person's personal network. For example, I'm going to trust a post on psychology from someone who frequently makes accurate posts on the topic more than I'm going to trust one from my crazy meme-posting uncle.

I would trust ignoring this factor if most people didn't have accurate estimations of the knowledge level of the people in their social networks? Has there been any studies examining how accurately people keep track of who they trust on what topics? Does this accuracy affect how accurately they detect false information spread in their social network?
