There is no way with existing platforms and algorithms. We need systems that actually promote the truth. Imagine if claims (posts) you see come with a score* that correlates with whether the claim is true or false. Such a platform could help the world, assuming the scores are good.
How to calculate these scores is naturally the crux of the problem. There's infinite ways to do it; I call these algorithms truth heuristics. These heuristics would consider various inputs like user-created scores and credentials to give you a better estimate of truth than going with your gut.
Users clearly need algorithmic selection and personalized scores. A one-size-fits-all solution sounds like a Ministry of Truth to me.
* I suggest ℝ on [-1,1].
-1 : Certainly false
-0.5 : Probably false
0 : Uncertain
0.5 : Probably true
1 : Certainly true
