Exposure to television coverage of Parkland mass shooting and post-traumatic stress disorder (PTSD) prevalence. Baseline included a distribution of 11.2% agents watching <4 h, 13.1% watching between 4–7 h, 10.8% watching between 8–11 h, and 64.9% watching 12 h or more. Scenario 1: agents watched television <4 h per day. Scenario 2: all agent preferences were shifted to the lower half of population television watching distribution (i.e., all agents either watched 4 or less h or 4–7 h of television coverage). Scenario 3: all agent preferences were shifted to the upper half of population television watching distribution (i.e., all agents ether watched 8–11 h 12 or more hours of television coverage).
