It's not the moderators' job to decide what's true and impose that decision on everyone else. The community would hate it if we tried to run HN that way—it's probably one of the few things that political enemies would come together and agree on.

We don't have a truth meter [1]. It's the community's job to sort out what's true and false. It's the mods' job to (try to) ensure that people (try to) do that through thoughtful, respective conversation rather than flamewar, snark, or attacks, in keeping with the site guidelines: https://news.ycombinator.com/newsguidelines.html.

It's easy and all too satisfying to imagine that if the mods would simply impose your idea (<-- I don't mean you personally, but any of us) of what's true and false, what's lies and misinformation, etc., then the site would get magically and massively better. However, different users have radically different sets of what they consider true vs. lies—why should we select one and not another? This would just be a different way of imposing our own viewpoint on the community. It's not our temperament to do that, and as I mentioned, the community would never tolerate it.
