"I suggest that some form of superstitious behavior will be eternal," Stevens said. "Some form of magical thinking will also be evident, because it gives us some measure of control. The world is vast, complex, impersonal, unpredictable and the sense that one has little bit of control over things is comforting."
So whether avoiding black cats, cracks on the sidewalk or looking over your shoulder on Friday the 13th, Stevens says it all makes you perfectly human.
