I'm not sure if your first example "Ignoring information they cannot immediately fit into a framework" includes "sticking to an elegant, logical framework and considering cases where this does not occur to be exceptions or aberrations even when they are very common".

That's something you see quite a lot with some otherwise quite rational people: the 'if my system can't explain it, the world's wrong' attitude'. As illustrated here: http://xkcd.com/1112/
