In my experience it ends up just being more divise, the more an institution that one group of people do not trust doubles down on a story the more likely they are to become convinced of the opposite position, whereas those that thought it was true become more convinced. To quote Dr. Robert Calidini in his book Pre-Suasion. "The media is great at telling people what to talk about, but terrible at telling people what to think about it.", basically you can use media streams to get people to focus on something but you cannot use it to get them to believe a certain thing about it. The results will be more polarization as one group of people on any issue will have less trust in twitter, and the other side will use the proof of everyone knowing it is true. As I've been reading a recent book about the USSR right before and through WW2 (Ivan's war, good book by the way highly recommend it) it shows how the purpose of propaganda isn't about making you thinking a certain way, but rather making you feel isolated and convince you, that you are alone.
