Groupthink: A Study in Self Delusion

With reference to the ideas of a Yale professor who first identified the theory, and to the writings of George Orwell from whose 'newspeak' the word was adapted, Booker sheds new light on the remarkable – and worrying – effects of 'groupthink', and its influence on our society.

Booker defines the three rules of groupthink: the adoption of a common view or belief not based on objective reality; the establishment of a consensus of right-minded people, an 'in group'; and the need to treat the views of anyone who questions the belief as wholly unacceptable. He shows how various interest groups, journalists and even governments in the twenty-first century have subscribed to this way of thinking, with deeply disturbing results.

As Booker shows, such behaviour has led to a culture of fear, heralded by countless examples throughout history, from Revolutionary Russia to Napoleonic France and Hitler's Germany. In the present moment it has caused countless errors in judgement and the division of society into highly polarised, oppositional factions.

As Booker argues, only by examining its underlying causes can we understand the sinister power of groupthink which permeates all aspects of our lives.
