A new study co-authored by CU Boulder sociology professor David Pyrooz reveals that 7% of the U.S. population have witnessed a mass shooting. The research, based on a nationally representative survey of over 44,000 Americans, also found that people who have experienced mass shootings are more likely to suffer from psychological distress and hold more negative views of police. Pyrooz shared about his research with Science Writer for CU Boulder Today, Lisa Marshall. He emphasized the importance of understanding the broader societal consequences of mass shootings for victims and communities.
