Positive psychology is a field of psychological theory and research of optimal human functioning of people, groups, and institutions.[1][2] It studies "positive subjective experience, positive individual traits, and positive institutions... it aims to improve quality of life."[3]
Positive psychology largely relies on concepts from the Western philosophical tradition, such as the Aristotelian concept of eudaimonia,[7] which is typically rendered in English with the terms "flourishing", "the good life" or "happiness".[8] Positive psychologists study empirically the conditions and processes that contribute to flourishing, subjective well-being, and happiness,[2] often using these terms interchangeably.
Positive psychologists suggest a number of factors that may contribute to happiness and subjective well-being, for example: social ties with a spouse, family, friends, colleagues, and wider networks; membership in clubs or social organizations; physical exercise; and the practice of meditation.[9] Spiritual practice and religious commitment is another possible source for increased well-being.[10] Happiness may rise with increasing income, though it may plateau or even fall when no further gains are made or after a certain cut-off amount.[11]
