Regression toward the mean. That is, in any series of random events an extraordinary event is most likely to be followed, due purely to chance, by a more ordinary one.

Nonverbal communication forms a social language that is in many ways richer and more fundamental than our words.

That's why successful people in every field are almost universally members of a certain set - the set of people who don't give up.

We believe that when we choose anything, judge a stranger and even fall in love, we understand the principal factors that influenced us. Very often nothing could be further from the truth. As a result, many of our most basic assumptions about ourselves, and society, are false.

We judge people and initiatives by their results, and we expect events to happen for good, understandable reason. But our clear visions of inevitability are often only illusions.

Our inner weighing of evidence is not a careful mathematical calculation resulting in a probabilistic estimate of truth, but more like a whirlpool blending of the objective and the personal. The result is a set of beliefs - both conscious and unconscious - that guide us in interpreting all the events of our lives.

When we are in the grasp of illusion - or, for that matter, whenever we have a new idea - instead of searching for ways to prove our ideas wrong, we usually attempt to prove them correct. Psychologists call this the confirmation bias, and it presents a major impediment of our ability to break free from the misinterpretation of randomness.
