The Delusions of Crowds

Inspired by Charles Mackay’s 19th-century classic memoirs of ‘Extraordinary Popular Delusions’ and the ‘Madness of Crowds’, William Bernstein engages with mass delusion with the same curiosity and passion, but armed with the latest scientific research that explains the biological, evolutionary, and psychosocial roots of human irrationality. Bernstein tells the stories of dramatic religious and financial mania in western society over the last 500 years – from the Anabaptist Madness that afflicted the Low Countries in the 1530s to the dangerous end-times beliefs that animate ISIS and pervade today’s polarised nations; and from the South Sea Bubble to the Enron scandal and dot com bubbles of recent years.
