In study after study,researchers have found that people who are more similar genetically are also more similar in terms of their IQ scores.These research findings seem to strongly support the genetic contribution to intelligence.Why are some researchers still skeptical that genes have a larger influence on intelligence than environment?

Question

The skepticism among some researchers regarding the larger influence of genes over environment on intelligence is due to multiple factors: A) the observation that identical twins raised apart still show high IQ correlations suggests a genetic component, but doesn't exclude environmental influences; B) the possibility that the more similar environments of identical twins could contribute to their higher IQ score correlations, challenging the assumption that these correlations are solely due to genetics; and C) the fact that adopted children show higher IQ correlations with their biological parents than with their adoptive parents supports a genetic link, but also raises questions about the role of the environment in which they are raised. These points collectively suggest that while genetics play a significant role in intelligence, the influence of the environment is also substantial and complex, leading to ongoing debate and research in the field.
