I'm already aware of popper and his falsification, but I'll spend a bit more time on the article, thanks. My problem is I can easily and happily change my mind if the evidence is concrete but where it is more a matter of common sense I tend to fail; "This is interesting and fun and may be useful - is it worth investing the time in?" And because it is all these, I seduce myself into spending the time on it whereas I suspect it may not be the best use of my time. Deffo not my strong point, that... Going back to the original issue of evidence swaying (or not) people, I really feel lost looking at how to some people, reality is just a hindrance to what they know to be true.
