Some argue that inherited genetic differences play the dominant role in cognitive ability, while others emphasize the importance of education, nutrition, family environment, and life experiences. Based on genetic research, psychological studies, educational data, and long-term human development research, what does the available evidence suggest about the primary factors influencing intelligence?
