Why do trends in human society sometimes change so suddenly? The past three years show how quickly cultural shifts can occur, which makes answering the question above all the more urgent. In 1999, we were celebrating our heroes, the stock market had reached unprecedented heights - and many people believed that peace in the Middle East was at hand.

Three years later, the economy is weak, corporate executives are being thrown in jail, bloodletting between Israelis and Palestinians is daily ritual, India is testing missiles, North Korea is threatening the U.S. with nuclear destruction, the U.S. is at war with Iraq, European allies are deserting the U.S., a senator is calling for the resignation of the chairman of the Federal Reserve, and Americans are stocking supplies for terrorist attacks. What changed? And why?

Is it possible that all of these events flow from the same cause?

Best-selling author Robert Prechter's revolutionary new two-book set, Socionomics: The Science of History and Social Prediction, proposes a startlingly fresh answer. It spells out a historical correlation between patterned shifts in social mood and their most sensitive register, the stock market. It also presents engaging studies correlating social mood trends to music, sports, corporate culture, peace, war and macroeconomic trends.

Socionomics: The Science of History and Social Prediction includes the brand-new 2nd edition of the book that started it all, The Wave Principle of Human Social Behavior and the New Science of Socionomics as well as his new title, Pioneering Studies in Socionomics, a rich collection of the insightful studies and essays that founded a new basis for social science. Together, these books will transform your understanding of how society works. They will change the way you read the newspaper or watch the news. You'll learn how to predict news trends months in advance. Learn for yourself the science of social prediction here.
