Final answer:
High intelligence can come from various factors, including genetics and environmental influences. Studies have shown that intelligence scores tend to rise with a well-adjusted lifestyle, education, and opportunities for intellectual stimulation. Twins studies have also suggested a genetic component to intelligence.
Step-by-step explanation:
High intelligence can come from various factors, including genetics and environmental influences. Studies have shown that intelligence scores tend to rise with a well-adjusted lifestyle, education, and opportunities for intellectual stimulation. For example, a longitudinal study conducted by Lewis Terman in 1921 found that children with high IQs became successful, well-educated adults.
Furthermore, some researchers believe that intelligence has a genetic component, as evidenced by twin studies. The Minnesota Study of Twins Reared Apart showed that identical twins raised together and apart exhibit a higher correlation between their IQ scores than siblings or fraternal twins raised together.
It is also important to note that intelligence is not solely determined by IQ scores. Factors like grit, perseverance, and personal qualities can also contribute to academic success and achievement.
