The Human Potential Movement (HPM) arose out of the counterculture milieu of the 1960s and formed around the concept of cultivating extraordinary potential that its advocates believe to lie largely untapped in all people. The movement took as its premise the belief that through the development of "human potential", humans can experience an exceptional quality of life filled with happiness, creativity, and fulfillment. As a corollary, those who begin to unleash this assumed potential often find themselves directing their actions within society towards assisting others to release their potential. Adherents believe that the net effect of individuals cultivating their potential will bring about positive social change at large.
The emergence of HPM is linked to humanistic psychology. The movement is strongly influenced by Abraham Maslow's theory of self-actualization as the supreme expression of a human's life.
In the middle of the 1960s, George Leonard did research across the United States on the subject of human potential for the magazine Look. In his research, he interviewed 37 psychiatrists, brain researchers, and philosophers on the subject of human potential. He found that "Not one of them said we were using more than 10% of our capacity", which should not be misconstrued as an endorsement of the ten percent of the brain myth but which is a more general claim. During the course of this research, Leonard met Michael Murphy, the founder of the nascent Esalen Institute that at the time was running educational programs for adults on the topic of "human potentialities". Leonard and Murphy became close friends and together put forth the idea that there should be a human potential movement.
