Interesting. I am not so sure of the "science" but philosophically I try to do some these things, deliberately. Like everything important needs to be questioned. Questioning and thinking. However this is pie in the sky without evidence. Evidence and reason, and question, question, question, are at the core of my philosophy.
When I was at uni I used to rush in, get material, and start to research and outline my papers. I would do this whenever I had energy, so if it crashed I would be mostly done anyway. However I rarely finished early. I used to think about the issues. Then finish just before they were due.
Thinking takes time. Thinking through options takes more time than just following rules. I think that allows for more creativity because you have time to think outside of the narrow box you are forced into if in too much of a hurry to get it done.
Hmmm, maybe I rushed into this response too fast. Let me think about it.
