It comes down to Bayes theorem, and what prior distribution you have. Then you update this with observations, and the distribution shifts. However, if you give a 0 probability to some set, it will stay 0 whatever you observe. So does a pure skeptic start off with a prior that can be updated?
A person is logical if they update their beliefs based on Bayes theorem, but that still means that two logical people could be in different states based on what they have observed to date and what their starting distributions were. However, for most starting distributions and a lot of observational data most logical people tend to converge to the same distribution.
The amazing thing in many of Randi's videos is that people do not change their minds in a Bayesian way, when they are shown in some sense to be wrong.
So, I think it is possible for someone to put a reason weight on a belief in god, and still behave logically from that point on. So what you should ask is what observations should logically reduce this belief in god.
To me, one's belief in god should dissipate as one realizes others hold contradictory beliefs based on equally compelling "evidence". If some gods are wrong (and some must be for any of them to be right), then the god belief that is correct has no more evidence for it than all the ones that are wrong. If people can believe in things like demons and be wrong, then how do we know that all invisible entities aren't equally wrong and for the same reasons? Those are the kinds of thought that lead to my disbelief.
But Randi has often commented on how none of the people tested change their minds after their failures... they just feel like their powers weren't working or there were bad vibes etc. The human mind is very good at protecting it's ego. I don't understand how anyone can watch Randi's demos and not question their own similar beliefs... and once one examines those beliefs--how can one continue to believe in their validity? It seems like a person must be concluding-- "yes, most people are very easy to fool-- but not me." And that's arrogant to me. Or delusional. Or maybe just protective cognitive dissonance. But whatever it is, it just doesn't seem "skeptical" to me.
