Problem then is: the believers of lies simply do not trust (an certain topics at least) the unbiased sources. I've been thinking about augmenting social networks with some measure of trust (eg. express that I trust my uncle 90% when it comes to car repairs but 5% when it comes to vaccines). But then eventually, we'll see N groups again. Nothing new there. But maybe by expressing trust(-per-topic) new misinformation will spread less quickly?
