Definitely one of the most useful posts I've seen on overcoming bias. I shall be referring back to this list often. I am surprised though, that you did not reference that incisive philosopher, Humpty Dumpty, who had views about a word meaning exactly what he wanted it to mean :) While I haven't thought through the taxonomy of failures through quite as thoroughly, I spent a fair amount of time figuring out the uses of the words 'strategy' and 'tactics' in collaboration with a philosopher of language, and wondering about the motivated bias that enters into deliberately making these ambiguous words more fuzzy than they need to be. The result was a piece on the semantics of decision-making words. Somewhere in this dictionary, there is also probably a need to connect up with notions of conceptual metaphor (Lakoff) and the Sapir-Whorf hypothesis. It'll probably come to me in a day or two. Something connecting intent, connotation, denotation... hmm.
