This book is a stand-alone sequel to "Predictions: Society's Telltale Signature Reveals the Past and Forecasts the Future" (Simon & Schuster, New York, 1992), which provided a new way of understanding society and ourselves by applying scientific concepts to predicting social phenomena. In addition to taking up the challenge of confronting the predictions made 20 years ago with actual data-something forecasters generally refrain from doing-this book includes many new topics that became relevant more recently.
