That all depends on your level of competence.
No it doesn't. It depends on the evidence. And you would be a fool to try the trick of "argument to authority" against this, when these are lifelong scientists performing these experiments. Oh, and all are producing the same results. Every time, without fail.
You literally have to have conscious thought about things you don’t know like the back of your hand.
Nobody is denying that the conscious mind doesn't take in and process information. Surely you don't think you just outsmarted people who have dedicated their lives to this science, and have thought of something they have not. Or, maybe you do ... that's another bad habit of yours, actually. Which, of course, is used to support another bad habit of yours: dismissing evidence so you don't have to account for it.
