I was listening to a project proposal the other day and had a similar set of questions to guide the conversation. It was actually with a psychologist and I think that field and way of thinking represents the exact flip side of the type of rational thought that is reinforced and developed by programming. I'll likely end up turning down the project; my biggest fear is getting sucked into something that won't conclude well, so I'm going to use this fleshed out guideline next week and see how many of the steps I can reach clarity on.
