Maybe this is a technological problem with a technological solution?

This strikes me as being a sort of blindness to the epistemic web-of-supporting-knowledge. What we claim to know is ultimately supported and reinforced by other propositions that are consistent with it. There is a view of reality defined by the proposition that vaccines do more harm than good, and there is a small web of propositions that stand in support of this; but its a very small web and it stands in opposition to far more propositions than are in its web.

What if there was some kind of page-rank for ideas we see on the internet? What if it was made obvious, in your web browser or something, that you were viewing information that had a very low epistemic probability based on the amount of supporting information on the web? Maybe we're 10 or 20 years out from whatever technological solution could accomplish this (AI, clever algorithms, ... ?) but I really think that sometimes people just have a hard time seeing or understanding the sheer scale of evidence that is opposed to their flawed beliefs.
