Q: Do people with serious mental health disorders pose a greater risk of becoming mass shooters?
A: People with mental illnesses are somewhat more likely to be violent than those without a diagnosis. But a majority are never violent, and very little is known specifically about mass murder.
In the wake of the Florida school shooting, politicians have raised concern over the influence of violent video games and films on young people. Scientists still debate the issue, but the majority of studies show that extensive exposure media violence is a risk factor for aggressive thoughts, feelings and behaviors.
