People who are more rational don't perceive emotion less, they just regulate it better. - Jonah Lehrer

There is something scary about letting ourselves go. It means that we will screw up, that we will relinquish the possibility of perfection. It means that we will say things we didn’t mean to say and express feelings we can’t explain. It means that we will be onstage and not have complete control, that we won’t know what we’re going to play until we begin, until the bow is drawn across the strings. While this spontaneous method might be frightening, it’s also an extremely valuable source of creativity…the lesson about letting go is that we contain our own creativity. We are so worried about playing the wrong note or saying the wrong thing that we end up with nothing at all.

A few years ago, Tor Wager, a neuroscientist at Columbia University, wanted to figure out why placebos were so effective. His experiment was brutally straightforward: he gave college students electric shocks while they were stuck in an fMRI machine. (The subjects were well compensated, at least by undergraduate standards.)

People assume that they perceive reality as it is, that our senses accurately record the outside world. Yet the science suggests that, in important ways, people experience reality not as it is, but as they expect it to be.
