it's how our brains evolved to work - but we now have access to more information than ever and the optimum strategy is to go against our biological programming and actively seek out missing information instead of allowing the brain to fill it with assumptions.
i tried to explain this to a moron ( a mechanic ) and he just made up some BS excuse like " but what if you don't have access to information, and you have lost the skill of making BS assumptions ? "
clearly some people enjoy being dumb and can't be helped.
