Action Quote by Michael Gazzaniga
“Experiments on split-brain patients reveal how readily the left brain interpreter can make up stories and beliefs. In one experiment, for example, when the word walk was presented only to the right side of a patient's brain, he got up and started walking. When he was asked why he did this, the left brain (where language is stored and where the word walk was not presented) quickly created a reason for the action: I wanted to go get a Coke.”

In simple terms: The brain invents reasons for actions even when it lacks the facts.
