Minnesota Twin Family Study

The Minnesota Twin Family Study is a long-term research project that examines the roles of genetics and environment in human behavior and traits. It focuses on twin pairs, both identical and fraternal, raised together and apart. By analyzing similarities and differences in these twins, researchers gain insights into how much of our personality, intelligence, and mental health is influenced by inherited factors versus upbringing. The study has contributed significantly to our understanding of nature versus nurture and has implications for psychology, psychiatry, and social policy.
