Yes. It took humans centuries, millennia, or a couple hundred millennia, depending on how we think about it, to slowly, as a group of millions of people, develop the systematic checks and filters on our thinking that we call mathematics and science.
The surprise is having inherited that, some of us think checking our own beliefs this way is natural. We are healthy skeptics of ourselves.
That many people honestly (and I believe it is generally honest) don't "get it", don't understand how easy it is, for each of us to fool ourselves, is the unsurprising thing.
We did not evolve to discover solid truths. Just to navigate natural and social environments full of correlations, unlikely ever to be well understood, and statistically survive. Natural "beliefs" were/are simply imprinted correlations, adopted heuristics, or social identification, that upon being fixed, let us stop wasting time rethinking the incomprehensible. The pinnacle of innovation until recently.
