Complex Decision? Don't Sleep On It

"Neither snap judgements nor sleeping on a problem are any better than conscious thinking for making complex decisions, according to new research," reports PhysOrg. "In the new study, to be published in The Quarterly Journal of Experimental Psychology, scientists ran four experiments in which participants were presented with complex decisions and asked to choose the best option immediately (blink), after a period of conscious deliberation (think), or after a period of distraction (sleep on it), which is claimed to encourage unconscious thought processes. The finding debunks a controversial 2006 research result asserting that unconscious thought is superior for complex decisions, such as buying a house or car. If anything, the new study suggests that conscious thought leads to better choices."
