The fact that hype exists doesn't prove that something is not important.

The adage that fact is stranger than fiction seems to be especially true for the workings of the brain.

Science is like a love affair with nature; an elusive, tantalising mistress. It has all the turbulence, twists and turns of romantic love, but that's part of the game.

It may well be our brains are wired up to be slightly more optimistic than they should be.
