The Politician Within Me book casts a new look at a practice and science that we have known for a long time, which is affecting the process of people's social (political) decision-making. This has been done by the presupposition that man is wise and rational. However, new theories suggest that the idea of a rational man has been unrealistic. In this book, the author tries to say, the idea that "Providing information results in better decision making, and the reason that people make wrong decisions is ignorance and unawareness of the facts" is not a correct idea and many individual and social decisions of human beings are unconsciously made. Following this claim, the author strongly believes that at least in the field of social and political decision-making, a politician within our brain, independently from us, makes decisions and surprisingly gives us the hallucination that we have actually made that decision with rational reasoning and evidence.
