ImportanceDespite broad public support for gun safety policies, minimal policy implementation has occurred.ObjectiveTo investigate factors that encourage greater private support for and public action on gun safety policy.Design, Setting, And ParticipantsThree studies were conducted: a public opinion survey (Study 1) was conducted from January 8 to 22, 2019, and 2 experiments (Studies 2 and 3) were conducted from August 27 to October 17, 2019, and April 15 to 21, 2020, respectively. Adults living in the US were eligible to participate in Studies 1 and 3. Students 18 years and older participating in a research experience program were eligible to participate in Study 2. Study 1 was administered online by Ipsos, a market research company. A nationally representative sample of 1000 US adults was obtained from Ipsos' online KnowledgePanel, of whom 508 completed the public opinion survey. For Study 2, which was conducted in a university laboratory, 354 participants were recruited from a university research pool, all of whom completed the study. Study 3 was administered online by the market research company YouGov, which identified 727 US gun owners from its opt-in panel, from which it constructed a census-matched sample of 400 participants.ExposuresParticipants read a statement about the 2018 Marjory Stoneman Douglas High School shooting. Content was manipulated as a 2 (corrective information vs no corrective information) × 2 (system changeable vs system not changeable) between-subjects factorial design with random assignment. The corrective information included polling data highlighting widespread support among gun owners for several gun safety policies. System changeable described gun safety policies passed by Florida's legislature.Main Outcomes And MeasuresMain outcomes were support for gun safety policies and public disclosure of support.ResultsThe 3 studies included a total of 1262 participants (Study 1: 508 participants; weighted mean [SD] age, 47.7 [17.5] years; 261.9 women [51.6%]; 82.5 Hispanic [16.2%] and 60.3 Black [11.9%]; Study 2: 354 participants; mean [SD] age, 20.0 [2.3] years; 232 women [65.9%]; 100 Asian [28.3%] and 37 Black [10.5%]; Study 3: 400 participants; weighted mean [SD] age, 52.1 [16.4] years; 187.3 women [46.8%]; 295.5 White [73.9%], 44.5 Hispanic [11.1%], and 32.4 Black [8.1%]). Study 1 found that 63% to 91% of gun owners and 83% to 93% of non-gun owners supported key gun safety policies, yet both groups significantly underestimated gun owners' support for these policies by between 12% and 31%. Studies 2 and 3 found that exposure to corrective information was associated with a small increase in support for 2 gun safety policies of between 4% and 15%, both in terms of participants' privately held beliefs and the beliefs they would be willing to share publicly.Conclusions And RelevanceThis survey study found that many US adults failed to recognize that most gun owners support key gun safety policies. Correcting this misperception was associated with greater private and public support for gun safety policy.
