Sleeping on a big decision, such as buying a car or house, is more likely to produce a result with which people remain happy than consciously weighing up the pros and cons of the problem, based on the findings of Ap Dijksterhuis, Ph.D at the University of Amsterdam in the Netherlands, in his classic article, ‘Sleeping on it.’.
“Complex decisions are best left to your unconscious mind to work out, according to a new study, and over-thinking a problem could lead to expensive mistakes. The research suggests the conscious mind should be trusted only with simple decisions, such as selecting a brand of oven glove.”
“Thinking hard about a complex decision that rests on multiple factors appears to bamboozle the conscious mind so that people only consider a subset of information, which they weight inappropriately, resulting in an unsatisfactory choice. In contrast, the unconscious mind appears able to ponder over all the information and produce a decision that most people remain satisfied with.”
Dijksterhuis said, “We found that when the choice was for something simple, such as purchasing oven gloves or shampoo, people made better decisions – ones that they remained happy with – if they consciously deliberated over the information.”
“But once the decision was more complex such as for a house, too much thinking about it led people to make the wrong choice. Whereas, if their conscious mind was fully occupied on solving puzzles, their unconscious could freely consider all the information and they reached better decisions.”
The unconscious mind appears to need some instruction. “It was only when people were told before the puzzles that they would need to reach a decision that they were able to come up with the right one.” If they were told that none of what they had been shown was important before being given the puzzles, they failed to make good choices.
“At some point in our evolution, we started to make decisions consciously, and we’re not very good at it. We should learn to let our unconscious handle the complicated things,” Dijksterhuis concluded.
