This book explores how functional stupidity - uncritical and unreflective thinking within prescribed, constrained ways - is institutionalised and why we should minimise it at workplaces. How did our organisations become stagnant, and what can be done to revive them? Contemporary societal and organisational noise, extensive bureaucratisation, silo thinking, imitation, bullshit talk, and meaningless meetings are destructive to workplaces. This book explains how we got here and shows escape routes through more independent thinking and speaking up. With spotlights on individual and organisational strategies to combat stupidity, various structures and practices to mobilise support are illuminated. A provocative and entertaining read, this book will be practically useful reading for all interested in making organisations more effective.
