That is difficult, yes. The way the game is played is a handful of large outlets promote themselves as “trusted” and then drown out everything else as “untrustworthy”. But the fly in the ointment for them is that even these large/sophisticated opinion manipulators (they shouldn’t be called news sources at this point) are inconsistent both over time and sometimes also in the moment. Today’s public short attention span prevents it from seeing such inconsistencies or from paying attention to the broader picture. But guess what today’s models easily outperform humans on? The ability to pay attention to more than a small handful of things for longer than a few minutes.
