When you write things down for GTD it shouldn't be done to help you make complex and preferredly rational decisions. It is done to help you remember, to relieve your mind from having to remember. Writing a task down is different from writing your reasoning for a decision down.
Fair enough; after thinking about it for a moment I realized that I probably mixed explicit reasoning with dumping information out of my head.
But still, does that mean that explicit cost-benefit analysis is bad? Or, when I'm confused about an issue I need to decide on, if I do a mind-dump of things related to that issue, does that lead to poor decisions? I'm asking, because so far I find it extremely helpful to do a mind dump, when I feel confused.
