Ap Dijksterhuis is a famous Dutch psychology professor and has written a lot about unconscious thought. He even has a Unconscious Lab, see: http://www.unconsciouslab.com/index.php?page=People&subpage=Ap%20Dijksterhuis http://www.unconsciouslab.com/index.php?page=People&subp.... You can find a lot of links to scientific papers on this website. He is also the author of a Dutch bestselling book on unconscious thought "Het slimme onbewuste". Unfortunately it has not been translated in English. In an article on the BBC website (http://news.bbc.co.uk/2/hi/health/4723216.stm http://news.bbc.co.uk/2/hi/health/4723216.stm) he says: "The take-home message is that when you have to make a decision, the first step should be to get all the information necessary for the decision. Once you have the information, you have to decide, and this is best done with conscious thought for simple decisions, but left to unconscious thought - to 'sleep on it' - when the decision is complex."
