Perhaps to some people under certain circunstances. That may even have happened to me at some point.Once we finally accept the fact that we do not know the truth, we can then choose from among the various options, and change it at any time. But then it stops being a ‘belief’ and becomes a matter of faith.
But what I was talking about was something else entirely.
Truth isn't a consumer good (although many a consumer good is labelled as "truth, ready to use"). Of particular pragmatic and practical significance is that having the goal of tapping into some sort of cosmic truth is infantile and harmful. We can't in good faith expect protection out of the sincerity of our beliefs: that would spiritual fraud of a considerable intensity. That would be (and is) cowardly abuse of our own ability to believe and have faith, with a side dish of misguided social expectations to boot.
All the same, it happens so often and so widely that it really harms one's faith in humanity's worth.
To the extent that we can talk about a sense of "truth", it can responsibly come only from honest and inherently provisional efforts at achieving awareness according to the circunstances and available resources. We perceive existence and interact with it, but we are not owed connection to cosmic truths if they even exist in the first place. That is for fanfic characters, not for mentally sane adults.
