The research team analyzed posts from members of the 117th Congress on X over a two-year term. They identified thousands of gun-related posts and matched them to more than a thousand mass shooting incidents between January 2021 and January 2023. To test cause and effect, the authors combined causal discovery methods with statistical models and topic analysis.
Results showed Democrats were nearly four times more likely than Republicans to post about guns after mass shootings. Democratic posting rose within roughly two days and increased with shooting severity, especially when there were more fatalities or when the incident occurred in a lawmaker's home state. Republicans showed no similar causal response.
Topic analysis found clear differences: Democrats focused on legislation, communities, families and victims, while Republicans emphasized Second Amendment rights, law enforcement and crime. The authors note attention peaks immediately and falls within about 48 hours, so continued public pressure may be needed.

Discussion questions

- The article says attention falls within about 48 hours. Should the public keep pressure after that? Why or why not?
