"Rationality: The Antidote To Being Fooled By The Industry".
About this book: Inspired by Nassim N. Taleb's works The Black Swan, Antifragile, and Skin in the Game, Klaus Grobys explores how rationality and irrationality are manifested in human behavior across various domains of human life. The stories discussed in this book are based on real-life observations. This work deals with political incorrectness, the presence of concentration in virtually all domains of human life, the carelessness of industries manifested in profit-maximizing at the expense of simple folks, and various other issues that many authors typically avoid. The objective of this book is first to acquaint the reader with a new perspective concerning the concept of rationality and second to equip the reader to identify traps set up by profit-maximizing industries and self-serving lobbies.
