What you should focus on is TEACHING everyone how to learn and how to figure out what is a fact or not. If everyone was taught that we would all be better off.
The best thing to do would be to leave this alone completely, in terms of making a system of it. What you are talking about doing is shaping the way people think and will put people into "self selected echo chambers" and is dangerous. Your well meaning intentions of this as extremely misguided in my opinion, what you are also talking about doing is creating a sort of decentralized Chinese Social Media Score.... And we all know how that is used by governments...
