Much has been written in the last ten years about intuition, especially expert intuition. What’s so fascinating about intuition, of course, is the idea that one’s mind may work on a problem without one being aware of it.

Keith Richards put it this way:
Somewhere in the back of your mind, you’re thinking about this chord sequence or something related to a song. No matter what the hell’s going on. You might be getting shot at, and you’ll still be ‘Oh! That’s the bridge!’ And there’s nothing you can do; you don’t realize its happening. It’s totally subconscious, unconscious, or whatever.

Malcolm Gladwell’s book Blink was largely devoted to this phenomenon. Other books--e.g., Tim Wilson’s Strangers to Ourselves and Danny Kahneman’s Thinking Fast and Slow--have summarized some of the research showing that such unconscious cognition occurs, but Gladwell differed in suggesting that at times we’d be better off relying on intuition than in thinking. Some researchers--most consistently Gerd Gigerenzer at the Max Planck institute, but others, including Kahneman at times--suggest that advice might be sound.

A recent study, however, suggests you’re better off thinking.

 A group of researchers at Florida State and University of Leuven (Moxley et al, 2012) presented expert chess players with complex chess positions and varied the amount of time players were allowed to deliberate before they had to pick a move. The question was whether players benefited from more time. 

Experimenters also asked subjects to “think aloud” as they deliberated, so researchers could evaluate whether the first move subjects contemplated turned out to be the best one, even if further thought led them to pick another, inferior move.  (Move strength was evaluated by a computer program designed to make such evaluations--I won’t pretend to be able to evaluate its validity.)

Here are the results, for three different levels of problem difficulty.

This pattern--improved moves with more deliberation--was also observed in less expert players, but that finding is not terribly surprising. Expertise is thought to be the basis of intuition, so we expect that rapid intuitions of less expert players will not be as good, and that they will benefit from slower, deliberative processes.

More surprising is that experts showed the same benefit. Other studies (e.g., Burns, 2004) using a different methodology drew a different conclusion. For example, when playing speeded chess (which allows very little time for each move) the differences between good, very good, and expert players remains largely intact. So whatever it is that makes the best players the best, it can't be slow, deliberative processes, because there's no time for these processes to operate in speeded chess. It's been thought that the rapid, intuitive processes are due to pattern recognition of game positions.

Moxley et. al argue that the difference between their results and previous ones may lie in the fact that they examined move selection whereas Burns (and other researchers) have examined the outcome of entire games.

In the final analysis, the most apt conclusion seems to be that both pattern recognition and deliberative cognition are major contributors to expertise.

Is there a difference between deliberative thinking and what I would call delayed intuition? The difference would be that the first is something that is *caused* by the process of deliberation whereas the second is still a flash of insight, but it occurs after a delay. I'd imagine that think aloud might actually induce verbal deliberation in the latter case because of the social expectation to explain things that contradict each other.

I think most would say that these are different. A researcher named Ap Dijkersterhuis (dijksterhuis.socialpsychology.org/) has done some interesting research on the idea of this idea, that you can walk away from a problem, not think about it, but nevertheless be "working on it." There seems to be some truth to it (for at least some types of problems) and yes, it's thought to be different than the flash of intuition, which is thought to be supported by *recognizing* the solution, based on past experience.

If you want to throw off your tennis opponent, just ask them to explain to you how they are hitting the ball so well. This seems to be what the researchers did to the chess masters in this experiment. Ryan makes a good point: verbalizing an explanation will affect the "intuitive" flash of insight, just as the quality of these flashes are diminshed by caffeine, lack of movement and people asking you to explain yourself. Intuition works best when more factors are synthesized at once and the conscious mind is quiet, which allows subtle intuitions to reach conscious awareness. Thinking out loud is great for data gathering, but then that information must be meshed into prior knowledge to create the intuitive flash of insight. Otherwise, it's not intuition, it's just thinking out loud. Intuitions can be explained after the intuitive flash occurs, not before. So I suspect that the chess masters might make better choices when using their unbridled intuition. The experiment should be repeated, with the masters playing as they prefer and not explaining their moves.

I am interested in how the word intuition is used as I read entries online. Most often it is presented as being what is actually logic based on faulty premises. Also, this "putting on the back burner" aspect is more of a cognitive behavior where the brain does its thing with the information it has, similar to a computer working on a program with data input. Another way intuition is explained is as being behavior that is actually based on experience. At any rate, intuition has nothing to do with brain activity, other than the brain has the tools to recognize it and then either believe or disbelieve what is before it.

With the chess game, a truly intuitive behavior would be to see the entire game before it was played or at least the other player's moves before made.

I work with intuitive people. I have seen people manipulate their blood pressure and heart rate to a cited number. I have seen people hold things they have never seen before and say where it is kept and what the owner's personality is like. Sometimes they amaze themselves!

Intuition is about getting information from the unseen world, that of energy. Quantum physics is coming closer to explaining how this works, but people in other-than-western-cultures have known and honored it for a long time. The recent studies of the heart which have shown that the heart also has neurons confirm that intuition comes to us through the heart.
