Which theory emphasizes the importance of genetic makeup in determining intelligence?

The theory that emphasizes the importance of genetic makeup in determining intelligence is the nature theory. This perspective posits that many characteristics, including intelligence, are primarily influenced by biological factors, particularly genetic inheritance. Advocates of this theory argue that an individual's traits and potential can be largely predetermined by their genetic background, thus shaping their cognitive abilities and intelligence levels.

In the context of juvenile delinquency, understanding the influence of genetic factors can provide insight into the risk of engaging in delinquent behavior. It recognizes that while environment plays a crucial role, certain predispositions linked to genetics may also influence an individual's propensity toward certain actions or behaviors.

The alternative perspectives such as nurture theory focus more on environmental influences and experiences, behavioral theory emphasizes learned behaviors and responses to stimuli, and psychodynamic theory considers unconscious motivations and internal conflicts, which differ fundamentally from the emphasis on genetics present in the nature theory.
