The effect of mass shootings on daily emotions is limited by time, geographic proximity, and political affiliation

Our study provides causal evidence of how a mass shooting affects the emotions of residents throughout the city and state where the event occurred. We found that mass shootings have a strong impact on the emotions of individuals, but the impact is politicized, limited to individuals living within the town or city where the incident occurs, and fades within a week of the incident. The findings provide evidence on the full emotional toll of mass shootings while also offering insights into the link between mass shootings and gun politics.
