The main subject of this book is behavioral economy. The main idea is that in some situations and cases people’s decisions are systematically following an irrational pattern. We all know from our experience that we are not totally rational but it is behavioral psychologist’s job to decide in what circumstances we intend to decide irrationally.

We are speaking of a hypothesis and a model when we talk about wise and rational decisions. The way in which economists believed for many years had been people’s main method of thinking and decision making (economists in all economic periods believed that they could predict people’s mind and behavior)

Being irrational or unwise in behavioral economics literature and Dan Ariely’s book means that people’s behavior doesn’t match the pattern in which traditional economists used to know.

By using “irrational” he emphasized that this form of rationality is not a suitable model to understand people, and people don’t tend to think and behave the same way in most situations.
