Researchers have explored how music preferences can relate to psychological traits, emotional experiences, and social behaviors, but identifying causal links is challenging due to the complexity of human behavior. Many other factors, such as personal upbringing, social environment, life experiences, and individual personalities, can influence the development of aggressive tendencies.
It is essential to avoid generalizations and note that music is often one of several factors that interact to shape a person's beliefs, attitudes, and behaviors. Music and other forms of art provide diverse outlets for self-expression and emotional release without directly leading to aggression or violence.
If you have concerns about an individual's behavior, it's best to assess their specific circumstances and seek professional guidance or support rather than solely relying on music preferences as an indicator of potential aggressiveness.
