This is just adding a blackbox filtering the output of another black box.
A democratic discussion does not need "truth filters". The proposition is insane.
2014 is significant, as it is 1 year after the IRA went online in early 2013 and Cambridge Analytica was also in operation. The new techniques they unleashed haven't gone away and there are copycats all over the place.
I see no solution short of a massive education campaign for every person in society as to what the human brain flaws are in regard to favoring mythological media patterns. A history of humanity favoring nonsense and falsehoods, a map to the weak spots in the human brain. Machine thinking has been doing sorting the output of social media for a long time now on media platforms, and 'trending' has proven for a decade to be a race to the bottom of exploiting flaws in both the hardware of the human mind and our lacking education on faults in chasing false signals.
At about the same time these "Bod Dylan has died" fake click baits raged at Facebook, and somehow they stopped. It is probably also related.
This assumes universal good faith. The reality is that there's a war against actual democratic discussions, and that bad actors are currently arming themselves with AI-powered weapons which will exponentially amplify their ability to harm and ultimately destroy legitimate discourse.
To choose not to defend democratic discussion is akin to having a country without a military.
