I don't think I look particularly stupid; rather I think it is just that I never seem to "know" anything.
I've evolved (regressed?) to the point that I consider most important values, decisions, and preferences to be probabilistic, not solid and specific. You arrive at decisions and beliefs based on the "best" information and value-system available to you at the time, but we all know that things change.
The hard part is changing your opinion when the reasons for your original stance change enough to warrant doing so.
It's a framework that lets me feel comfortable about having made the "right" decision even when it turns out to be wrong (I figuratively bet on a full house and the opponent had a straight flush - right decision, undesired result, but no regrets about betting).
At least that's the theory. Real life: I waiver, cling, and do all the other "human" screw-ups as often and the next person, I suppose. Somehow it all works out pretty well most of the time.
