Quizplus · Accepted Answer

Research has shown that intelligence is not simply related to the overall size of the brain. While there are correlations between certain structural aspects of the brain and intelligence, such as the volume and density of gray matter in specific regions, the statement that people who score high on intelligence tests tend to have larger brains is not accurate. Intelligence is a complex trait influenced by both the structure and the functional connectivity of the brain, rather than its size alone.
