Some interesting cases are presented in the book of people choosing to act in ways that would be contrary to their best interests and the point the authors make is that they are stunned by this pull of irrational behavior that even affects expert professionals at their craft and the premise is that this tunnel-vision approach could affect anyone. What the authors miss, which is evident throughout history and in great literature is that man rarely serves his best interests. If he did, Utopia could be built in a year. It is human nature to work against your own best interests, the authors of the book treat it as an important discovery, while individuals of the world of all levels of education and experience continue to do what is not in their best interest, and act on whims, rather than consult some timetable of all possible good outcomes from a planned best interest way of life.
