Edward de Bono identified several types of thinking. He associated each with a coloured hat: White Hat Thinking is all about collecting information (imagine a white piece of paper). It would be of great benefit to Interactive Democracy (indeed any democracy) for politicians to identify what information is required for each issue and to fund the gathering of that information, perhaps through independent academics. This should be reported via a link on the ID web site.
(Edward de Bono created the term "lateral thinking")
