For about 30 years, Brad Bushman has studied the factors that cause human aggression, including violent media. He is a member of President Obama’s committee on gun violence, and has testified before the U.S. Congress on the topic of youth violence. He has published over 170 peer-reviewed journal articles. Google Scholar lists more than 25,000 citations for Bushman's articles, ranking him #2 among communication scholars cited. In 2014 he received the Distinguished Lifetime Contribution to Media Psychology and Technology from the American Psychological Association. His research has challenged several myths (violent media have a trivial effect on aggression, venting anger reduces aggression, violent people suffer from low self-esteem, violence and sex sell products, warning labels reduce audience size). One of his colleagues even calls him the "myth buster." His research has been published in top scientific journals including Science and Proceedings of the National Academy of Sciences and has been featured extensively in mass media including the BBC, New York Times and NPR.
