One solution is to recognize that, unfortunately, in that case you don't have much reliable knowledge about the world and therefore your default position should be to not try to influence it. Practically that means things like not judging other people, not voting, or alternatively voting for libertarians who don't believe in imposing rules on other people (because if you voted for specific rules, you'd be doing so based on unreliable information).

Luckily you don't have to actually research every single article. It's OK to generalize over time. Rules can also be shared. Here's some of mine: ignore any story about Russia because they're always unreliable especially since the war, ignore any study about science or public health, ignore any claims made by (ex)-intelligence agents, ignore any claims that appear to support woke narratives, ignore any statistical claims about China, ignore economic predictions or really anything that depends on academically developed statistical models.
