Dr. Abreu believes that intelligence is polygenetic, meaning it is determined by multiple genes interacting with each other. This is supported by research on twin studies and genome-wide association studies. The Flynn effect, the idea that intelligence scores have been increasing over the years, is not related to Dr. Abreu's belief about the genetic basis of intelligence. The idea that experience plays a role in intelligence is widely accepted, but Dr. Abreu specifically focuses on the genetic component. The family-environment effect, or the idea that family upbringing and environment influences intelligence, is also known to play a role but Dr. Abreu emphasizes the importance of genetic factors.
