Cosmides and Tooby (1997) stated that evolutionary psychology “is not an area of study, like vision, reasoning, or social behavior. It is a way of thinking about psychology that can be applied to any topic within it.” Evolutionary psychology is thus a lens that we can use to look at any aspect of human behavior. That lens can be used to examine what conditions are conducive to happiness and life satisfaction — the central concerns of positive psychology, an established field of research which studies the factors that increase such “positive” life outcomes. Positive evolutionary psychology is thus an integrative and applied discipline, i.e. it uses insights from both evolutionary and positive psychology to provide guidance for human flourishing. The leading figure in the field, Glenn Geher, Ph.D., defines positive evolutionary psychology as “the use of evolutionary principles to help people and communities experience more positive and fulfilling lives.”
