Trust is much more nuanced than N% wrong. You have to consider circumstantial factors as well. ie who runs The NY Times, who gives them money, what was the reason they were wrong, even if they’re not wrong what information are they leaving out. The list goes on. No single metric can capture this effectively.
Moreover, the more political a topic the more likely the author is trying to influence your thoughts (but not me I promise!). I forgot who, but a historian was asked why they wouldn’t cover civil war history, and responded with something to the affect of “there’s no way to do serious work there because it’s too political right now”.
It’s also why things like calling your opponents dumb, etc is so harmful. Nobody can fully evaluate the truthfulness of your claims (due to time, intellect, etc) but if you signal “I don’t like you” they’re rightfully going to ignore you because you’re signaling you’re unlikely to be trustworthy.
Trust is hard earned and easily lost.
