Well, I am not sure what the link is too strength or weakness, and taken as written, i would suggests that changing one's opinion, per se, is a sign of nothing at all: the question is why did you change your mind, and also, in terms of the current thread, did you at least have an opinion, or are we so willing to change our minds that we never assert anything.

Because that is politician's breaking promises. Scientists in fact promise to never become hide bound and when they do we accuse them of being short-sighted and illoyal villains too.
