Question

Quizplus · Accepted Answer

Adoption studies have consistently shown that both genetics and environmental factors play a role in determining intelligence. Children who are adopted into families with higher socioeconomic status tend to have higher intelligence scores, suggesting the importance of environmental factors. However, studies also indicate that genetic factors are important, as children tend to have higher intelligence scores if their biological parents have higher scores than their adoptive parents. These findings suggest that intelligence is a complex trait influenced by both genetic and environmental factors.
