"But actually the vast majority of your decision making is based on judgements without adequate evidence. "

Er, but this is not what we're talking about   We are talking about accepting without demur a highly-improbable notion that is at odds with everything else we experience and for which there is NO evidence. I know I set the bar high for evidence. But no higher than for anything else. And if it works for you, fine. I can't argue with that. What I can argue with is passing it on to others as if it were truth. Someone did that to you, which is why you believe. And millions of people are trapped in belief systems that do NOT work very well for them.
