Are people who listen to classical music smarter than rock music?

There is no scientific evidence to support such a claim. Musical preference does not reflect a person's intelligence or cognitive ability. Musical enjoyment is determined by personal taste and cultural factors, not by one's intellect. Intelligence is a complex construct influenced by various genetic and environmental factors. It encompasses many aspects, such as reasoning, problem-solving, learning ability, and social cognition, which are not directly linked to musical preferences.
