In a recent study, researchers did a meta-analysis of 437 other studies on narcissism and aggression. The meta-analysis looked at data from over 123,000 participants and found that narcissism is related to a 21% increase in aggressive behavior and an 18% increase in violent behavior.
Narcissism, simply defined is “entitled self-importance.”
Researchers stated that those who are highly narcissistic are especially aggressive when provoked but also aggressive otherwise. Participants with high levels of narcissism also demonstrated high levels of physical and verbal aggression, spreading gossip, bullying and even displacing aggression against innocents or strangers. They were seen to attack both in a hotblooded and coldblooded manner. Narcissism correlated with aggression in both males and females and in both Western and Eastern countries.
Researchers stated that people who think they are superior to others seem to have fewer qualms about attacking those they view as inferior. Research demonstrates that everyone is a little narcissistic but there are those with a much higher level of narcissism and that relates to their level of aggression. They also tend to be bad relationship partners, discriminate against others and are low in empathy.
Other studies have looked at a rise in narcissism. Some experts believe social media may be a factor. One study saw that people who posted a large number of selfies increased narcissistic traits by 25% in just four months. Another study found 85% of people are taking far more pictures of themselves than every before.
