Garen Wintemute, an emergency medicine physician and longtime gun violence researcher at the University of California, surveyed more than 8600 adults in English and Spanish about their views on democracy in the United States, racial attitudes in U.S. society, and their own attitudes toward political violence. Half expect a civil war in the United States in the next few years. (The survey didn’t specify when.) “The fact that basically half the country is expecting a civil war is just chilling,” Wintemute says. -Science.org
