Schopenhauer and Unconscious Thought

"Contrary to conventional wisdom, it is not always advantageous to engage in thorough conscious deliberation before choosing," according to a paper published in the latest issue of Science magazine.
Unconscious thought, defined as "thought or deliberation in the absence of conscious attention directed at the problem," can sometimes yield superior results, University of Amsterdam psychologists found. And they suggest that the same effect can be "generalize[d] to other types of choices -- political, managerial, or otherwise."
See "On Making the Right Choice: The Deliberation-Without-Attention Effect" by Ap Dijksterhuis, et al, Science, vol. 311, 17 February 2006 (free abstract).
So does that mean that the processes of political deliberation should be restructured to place greater emphasis on intuition and "hunches"? Not exactly.
The strengths and limits of "unconscious thought" were considered by author Sue Halpern in a review of Malcolm Gladwell's book "Blink" in the New York Review of Books (April 28, 2005).
..."Schopenhauer argued at length, and with a psychological insight which was altogether unprecedented, that empirical evidence points to the conclusion not only that most of our thoughts and feelings are unknown to us but that the reason for this is a process of repression which is itself unconscious," wrote Bryan Magee in his magnificent "The Philosophy of Schopenhauer" (Oxford, rev. 1997).
