Most things are provably true/false, or not broken down into fine enough detail.
In the minority of situations where it is genuinely indeterminate, you come to a consensus, just as happens between normal people millions of times each day on this planet.
Part of the problem is, politicians routinely pass legislation they know is wrong, knowing they can hide behind the "we didn't know, our intentions were in the right place" argument later because they know they will be let off the hook, even though everyone knows they are lying.
Governance has become such an "emperor has no clothes" scenario, where lying with impunity isn't given a second thought - no one would have believed you if you had predicted this state of affairs 100 years ago.
Processing all these lies on an ongoing basis sounds impossible, but if the media and the public actually started outing politicians and executives for their lying, they would stop doing it so much, making verification of genuine uncertainties much easier.
