Bruce K. Alexander

Bruce K. Alexander is a psychologist known for his research on addiction and the environment's role in behavior. He challenged traditional views by suggesting that addiction arises more from social and environmental factors rather than solely individual choice or brain chemistry. His famous "Rat Park" experiments showed that rats in enriched, social environments were less likely to develop drug dependency compared to isolated rats. This work emphasizes the importance of community, social connection, and environment in preventing and understanding addiction, highlighting that improving social conditions can reduce reliance on substances.
