David Lykken

DAVID LYKKEN is a behavioral geneticist and Emeritus Professor at the University of Minnesota. He is the proponent of a set-point theory of happiness, the idea that one's sense of well-being is half determined by genetics and half determined by circumstances. His research illustrates that a person's baseline levels of cheerfulness, contentment, and psychological satisfaction are largely a matter of heredity. He is the author of Happiness: What Studies on Twins Show Us about Nature, Nurture, and the Happiness Set Point.
