What does the term 'hereditary intelligence' refer to?

The term 'hereditary intelligence' specifically refers to the concept that intelligence is inherited genetically. This means that a certain portion of an individual's intellectual capabilities is determined by genetic factors passed down from their parents. Research in behavioral genetics has shown that both genetics and environment play crucial roles in the development of intelligence, but hereditary intelligence emphasizes the genetic component.

This concept is often explored through studies involving twins, particularly identical twins, as they provide insight into the influence of genetics on intelligence by comparing their similarities in cognitive abilities, even when raised apart. Overall, the idea that intelligence can have hereditary aspects continues to be an important topic in psychology, especially concerning discussions about nature versus nurture.
