During the past few decades, a small army of psychologists, social scientists, and scholars have asked the same question. Through rigorous experimentation and exhaustive surveys, they've given birth to a new science of happiness, focusing not only on defining the nature of human happiness, but also on discovering ways to improve our chances for personal well-being. Before we strike off around the world to learn the lessons of the world's happiness people, let's turn to some of the leading experts to understand the scientific fundamentals of the field:
Ed Diener, Ph.D., is Joseph R. Smiley Distinguished Professor of Psychology at the University of Illinois at Urbana-Champaign, and the author of Happiness: Unlocking the Mysteries of Psychological Wealth.
Sonja Lyubomirsky, Ph.D., is a professor of psychology at the University of California, Riverside, and the author of The How of Happiness: A Scientific Approach to Getting the Life You Want.
Ruut Veenhoven, Ph.D., is director of the World Database of Happiness and editor of the Journal of Happiness Studies.
