Our limbic brain is powerful, powerful enough to drive behavior that sometimes contradicts our rational and analytical understanding of a situation. We often trust our gut even if the decision flies in the face of all the facts and figures. Richard Restak, a well-known neuroscientist, talks about this in his book The Naked Brain. When you force people to make decisions with only the rational part of their brain, they almost invariably end up “overthinking.” These rational decisions tend to take longer to make, says Restak, and can often be of lower quality.
