6 Hats

When making a decision, look at the issue in turn with each of these hats on your head:
white hat: neutral, facts and numbers.
red: feelings
black hat: all the negatives, what could go wrong
yellow hat: sunshine, the upside
green: creative, new thinking, Alex Jadad's "what if" thinking. Just imagine!
blue: meta, thinking about the thinking. How am I going about this decision?
