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.

We also use our imagination and take shortcuts to fill gaps in patterns of nonvisual data. As with visual input, we draw conclusions and make judgments based on uncertain and incomplete information, and we conclude, when we are done analyzing the patterns, that out picture is clear and accurate. But is it?

Research suggests when it comes to understanding our feelings, we humans have an odd mix of low ability and high confidence.

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.

Says Bargh: "We all hold dear idea that we´re the captain of our own sould, and we´re in charge, and it´s a very scary feeling when we are not. In fact, that´s what psychosis is - the feeling of detachment from reality and that you are not in control, and that´s a very frightening feeling for anyone."

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.

One thing that feeds into the way you experience the social world is your mood - and one thing that affects your mood is the weather.
