I don't know if this ties in well or not, but many times over the years I have talked with otherwise reasonable people who had already, or were about to, make really stupid decisions, and I called them out as such: "this is a really stupid thing to do" - to which they all responded "are you calling me stupid?" - I never succumbed to the temptation of "well, if the shoe fits..." - truth, and what I said, was: "about this particular decision, yes." They always had some particular goal in mind which overrode all other considerations in their mind, and they couldn't step back and see how their goal wasn't 100% all important overruling all other considerations.
