It's at the core of Google algorithm: page rank. It uses 'trust'.
That actually maps to how we work as a society.
We cannot be experts in everything, we do not have the time, ability, wherewithal.
So we 'trust' certain sources: Teachers, Doctors, Lawyers, Judges, Police, more than we do others i.e. criminals, sources of gossip, arbitrary people.
This is why when people form those institutions fail us, it's a much bigger problem than otherwise. We should fire a teacher for teaching things that are wrong, but we don't worry about the guy walking down the street spouting nonsense.
Over time, we learn who to trust, and also the ways in which we can trust them. 'Nature' has a lot of credibility in some ways, but it also doesn't mean they are always right, and, when it comes to softer issue, they can be politicised.
Judges have more integrity than the average person, but they can also be biased.
The NYT is a good source of information, but it depends if it's 'straight news or opinion'.
Putin has a 'propaganda Army' of people trying to convince people of certain things, much of which are not true. People around the world will believe it if they are exposed to enough of it.
The Russian and Cheese population apparently are willing to believe that UKR government is a bunch of 'Nazis and Drug Dealers'. Which is perverse.
'Information Reputation' is a really big deal and the only way it will work as a society is if we give the 'Conch' to those with greater credibility, otherwise, people will believe in 'whatever'. You can tell people almost anything and 30% of them will believe it if they want to, which is enough people to tilt the needle on so many issues.
