Well said, I've talked about similar things in some of my posts. We should be curious, doubt and ask questions, but in doing so we create gaps, holes, voids, abysses and darkness in our comprehension due to not having an answer. That abyss is chaos, the unknown uncharted. The void in comprehension has fear to it, discomfort, insecurity, anxiety. We often fill in the gaps with a imagined idea, a belief. Then we feel secure and comfortable having our nice and even worldview or whatnot having no holes in it, at least according to out desire to believe whatever fills the gap created by a question. That's how I've described it before hehe.

Sometimes as you say, there is no answer. But, that doesn't stop many from adopting beliefs to fill in the gaps of the unknown.

There is also the fear of not admitting wrong, or else we appear less capable and lose a form of prestige or part of our social status.
