Well, I had thought about adding a winking-smiley. Would that have made it better? In all seriousness, at least some people who embrace GTD also have a high degree of faith in rationality and methodology. I've come to believe that we as humans don't work that way, even when we think we do. When my wife and I were in graduate school and had, ah, limited incomes (we were so poor we split a candy bar once a month as a treat), we used a very traditional method for making a decision: a table of decision factors with weights (we're both scientists). Quite often, the answer the method gave was one we both rejected. We always went with our gut in those cases, and never regretted it. So I would add "no method" to the list of methods, which is methodologically suspect but nevertheless correct.
