This document discusses the long-standing debate around whether nature (genetics) or nurture (environmental factors) has a greater influence on human development. It reviews perspectives from fields like psychology, criminology, philosophy and studies on topics like intelligence and the effects of family and peer relationships. While many experts have argued for either nature or nurture as the dominant factor, most modern psychologists view both as important influences that interact in shaping human development, with neither being solely responsible. The question of the relative impact of each remains an active area of research.
