IQ scores are influenced by both nature and nurture from "summary" of IQ and Human Intelligence by Nicholas Mackintosh
The idea that intelligence is a product of both genetic inheritance and environmental influences is a central theme in the study of IQ. This concept, known as the nature-nurture debate, has been a source of much discussion and controversy among psychologists and researchers. On one hand, there is evidence to suggest that genetic factors play a significant role in determining an individual's IQ. Studies of identical twins raised apart have shown that these individuals tend to have similar IQ scores, despite being raised in different environments. This suggests that there is a genetic component to intelligence that is independent of environmental factors. On the other hand, environmental influences also play a crucial role in shaping an individual's IQ. Studies have shown that children raised in stimulating and intellectually enriching environments tend to have higher IQ scores than those raised in less stimulating environments. This suggests that environmental factors such as education, socioeconomic status, and parental involvement can have a significant impact on an individual's intelligence. It is important to note that the nature-nurture debate is not a matter of either/or, but rather a complex interplay between genetic and environmental factors. Both nature and nurture interact to shape an individual's intelligence, with genetic factors setting the stage for potential and environmental factors influencing how that potential is realized.- IQ scores are influenced by a combination of genetic inheritance and environmental influences. While genetic factors may provide the foundation for intelligence, environmental factors play a crucial role in determining how that intelligence is expressed. The nature-nurture debate highlights the importance of considering both genetic and environmental factors in understanding human intelligence.
