The book explores the perplexing phenomenon of how intelligent and capable individuals often engage in seemingly irrational or counterproductive behaviors within organizational settings. It delves into the concept of "functional stupidity," where employees and leaders avoid critical thinking and questioning to maintain harmony and efficiency, ultimately leading to a lack of innovation and poor decision-making. Through a series of examples and analyses, the authors illustrate how this paradox manifests in various industries and suggest ways to foster a more thoughtful and questioning work environment to enhance organizational effectiveness.
