We look harder for flaws in a study when we don't agree with its conclusions.
Like sand on the beach, the brain bears the footprints of the decisions we have made, the skills we have learned, the actions we have taken.
Arguing, after all, is less about seeking truth than about overcoming opposing views.
The mind, of course, is just what the brain does for a living.
The conscious act of thinking about one's thoughts in a different way changes the very brain circuits that do that thinking.
The mind can store an estimated ioo trillion bits of information compared with which a computer's mere billions are virtually amnesiac.
