I don't think this is an accurate assessment. Yes, GTD wants you to get everything out of your head and onto the "paper" in front of you. And yes, this might take a long time for some people, up to hours or days. But the key thing is it's all written down. Once it is, then you go through the collected inputs and actually figure out what to do with them. But you can't do that while your brain is still going "did I write this other thing down?" You need a clear mind before you start processing.
