Good Lord, @mcogilvie, all I'm trying to do is suggest that if one is having trouble making a decision, there may be more work to do than just putting "make a decision" in an action list and for me it's worth clarifying what that work is -- while still allowing that someone else may have a different but equally valid method of handling things. And somehow even that's not reasonable enough to avoid gratuitous snark in these forums?
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.
