I agree with what you're saying, but I think people tend to jump to conclusions on the basis of short statements from posters. You might accuse me a snark, but I wouldn't draw further conclusions.I never doubted that, I just thought that was not what you were specifically expressing in that sentence (ie: your skepticsm (doubt) may be due to the skeptical manner in which you evaluated the cases, but in that sentence you only specifically mentioned the former). In the method definition, skepticsm is not ones ultimate position but rather the method used in reaching that position. Once can be quite confident in the truth of a claim and yet arrived at that conclusion skepticially.
In particular, I would doubt the complete veracity of these stories even if I had never read much about savants. That's because they are popular-press stories, which are quite subject to change and exaggeration over time. Also, people aren't very good at getting the right interpretation. For example, there is nothing in the Daily Mail story to suggest Padgett is a "math genius." He's just incredibly good at patterns and geometrical figures. This is a cool savant talent, but it's hyperbolized.
