alt Hacker NewsPeople believe in witchcraft and lots of other things - including many horrible prejudices - just as confidently as you. There's a reason any scholarship, courts, medicine, and any other serious endeavors require objective evidence.
Imagine that - doctors, who have seen everything, have years of study, treat all those people, still require objective evidence. Anyone in IT looks for objective evidence - timing, stepping through code, etc.
Confidence doesn't correlate well with accuracy; in fact the more someone expresses your kind of confidence, the less I rely on them at all.
What if you wrongfully accuse someone? Does that matter? Are you responsible for the consequences of what you do?
You turn your brain off and outsource your thinking to other people, because you're incapable of perceiving reality for yourself, is what you're telling me.
Of course everyone is responsible for their accuracy and their errors, doesn't mean it's impossible to infer things based on observation experience and intuition. This is an evolved ability, but I do agree some people are better than others like most things.
You're conflating a lot of things. Many prejudices are accurate and prudent, which craft is stupid, but so what? I'm not going to deny my perception on something that's correct just because some other idiot believes in magic; non sequitur.
