If yous desire to know what actual interrogation on the effects of diverse gun command policies take away keep to say, the RAND Corporation has your back. It has published a lengthy reports: "The Science of Gun Policy: A Critical Synthesis of Research Evidence on the Effects of Gun Policies inwards the United States," yesteryear a squad of 17 researchers led yesteryear Andrew R. Morral. Influenza A virus subtype H5N1 smaller grouping led yesteryear Morral also published "The Magnitude in addition to Sources of Disagreement Among Gun Policy Experts." And there's also a prissy accessible website alongside a summary of results in addition to links to these to a greater extent than detailed studies. They write:
The thirteen classes of gun policies considered inwards this interrogation are equally follows:They focus on high-quality studies published since 2003. They write:
1. background checks
2. bans on the sale of ready on weapons in addition to high-capacity magazines
3. stand-your-ground laws
4. prohibitions associated alongside mental illness
5. lost or stolen firearm reporting requirements
6. licensing in addition to permitting requirements
7. firearm sales reporting in addition to recording requirements
8. child-access prevention laws
9. give upwards of firearms yesteryear prohibited possessors
10. minimum historic stream requirements
11. concealed-carry laws
12. waiting periods
13. gun-free zones.
The viii outcomes considered inwards this interrogation are
1. suicide
2. fierce crime
3. unintentional injuries in addition to deaths
4. volume shootings
5. officer-involved shootings
6. defensive gun use
7. hunting in addition to recreation
8. gun industry.
"[W]e produced interrogation syntheses that describe the character in addition to findings of the best available scientific evidence. Each synthesis defines the cast of policies beingness considered; presents in addition to rates the available evidence; and describes what conclusions, if any, tin hold upwards drawn near the policy’s effects on outcomes. In many cases, nosotros were unable to pose whatever interrogation that met our criteria for considering a study equally providing minimally persuasive evidence for a policy’s effects. Studies were excluded from this review if they offered exclusively correlational evidence for a possible causal outcome of the law, such equally showing that states alongside a specific police had lower firearm suicides at a unmarried indicate inwards fourth dimension than states without the law. Correlations like these tin occur for many reasons other than the effects of a unmarried law, therefore this form of evidence provides fiddling information near the effects attributable to specific laws. We did non exclude studies on the footing of their findings, exclusively on the footing of their methods for isolating causal effects. For studies that met our inclusion criteria, nosotros summarize key findings in addition to methodological weaknesses, when present, in addition to render our consensus judgment on the overall forcefulness of the available scientific evidence."One primary termination is that the actual evidence is pretty thin. "Of to a greater extent than than 100 combinations of policies in addition to outcomes, nosotros works life that surprisingly few were the dependent area of methodologically rigorous investigation." For example, evidence on iv of the viii outcomes was "essentially unavailable," including defensive gun use, officer-involved shootings, hunting in addition to recreation, in addition to effects on the gun industry. None of the studies of waiting periods in addition to licencing in addition to permitting requirements take away keep reached to a greater extent than than inconclusive results. There are no methodologically audio studies at all on the effects of gun-free zones or requirements for reporting of lost or stolen firearms. I'll but listing the study's overall conclusions here:
Conclusion 1. Available evidence supports the decision that child-access prevention laws, or security storage laws, trim back self-inflicted fatal or nonfatal firearm injuries amidst youth. There is moderate evidence that these laws trim back firearm suicides amidst youth in addition to express evidence that the laws trim back total (i.e., firearm in addition to nonfirearm) suicides amidst youth.
Conclusion 2. Available evidence supports the decision that child-access prevention laws, or security storage laws, trim back unintentional firearm injuries or unintentional firearm deaths amidst children. In addition, at that spot is express evidence that these laws may trim back unintentional firearm injuries amidst adults. ...
Conclusion 3. There is moderate evidence that background checks trim back firearm suicides in addition to firearm homicides, equally good equally express evidence that these policies tin trim back overall suicide in addition to fierce criminal offence rates.
Conclusion 4. There is moderate evidence that stand-your-ground laws may increase nation homicide rates in addition to express evidence that the laws increase firearm homicides inwards particular.Of course, absence of evidence is non evidence of absence--that is, but because at that spot is a lack of evidence on surely policies or outcomes doesn't test that those policies don't work. But it does advise that a grade of humility powerfulness hold upwards appropriate on all sides. As a hopelessly out-of-touch academic, perchance at that spot could hold upwards bipartisan consensus on edifice upwards the information in addition to evidence therefore that meliorate studies tin hold upwards done, but maybe this is a province of affairs where neither side wishes to take away keep the peril tha their presuppositions powerfulness hold upwards rebutted. Or at to the lowest degree when gun command laws are passed, the police could include a specific provision for precisely how those laws volition hold upwards meaningfully evaluated a few years downwards the road.
Conclusion 5. There is moderate evidence that laws prohibiting the buy or possession of guns yesteryear individuals alongside unopen to forms of mental affliction trim back fierce crime, in addition to at that spot is express evidence that such laws trim back homicides inwards particular. There is also express evidence these laws may trim back total suicides in addition to firearm suicides. ...
Conclusion 6. There is express evidence that earlier implementation of a ban on the sale of ready on weapons in addition to high-capacity magazines, at that spot is an increase inwards the sales in addition to prices of the products that the ban volition prohibit.
Conclusion 7. There is express evidence that a minimum historic stream of 21 for purchasing firearms may trim back firearm suicides amidst youth.
Conclusion 8. No studies coming together our inclusion criteria take away keep examined required reporting of lost or stolen firearms, required reporting in addition to recording of firearm sales, or gun-free zones. ...
Conclusion 9. The little growth inwards cognition near the effects of gun policy over the yesteryear dozen years reflects, inwards part, the reluctance of the U.S. authorities to sponsor locomote inwards this expanse at levels comparable to its investment inwards other areas of populace security in addition to health, such equally shipping safety. ...
Conclusion 10. Research examining the effects of gun policies on officer-involved shootings, defensive gun use, hunting in addition to recreation, in addition to the gun manufacture is virtually nonexistent.
Conclusion 11. The lack of information on gun ownership in addition to availability in addition to on guns inwards legal in addition to illegal markets severely limits the character of existing research. ...
Conclusion 12. Crime in addition to victimization monitoring systems are incomplete in addition to non all the same fulfilling their hope of supporting high-quality gun policy interrogation inwards the areas nosotros investigated. ...
Conclusion 13. The methodological character of interrogation on firearms tin hold upwards significantly improved.
Follow-up on 3/13/18: Faithful reader DK reminds me that Congress blocked the populace wellness authorities from doing interrogation into gun command issues dorsum inwards the 1990s, equally the New York Times but reported. I'm pretty much e'er inwards favor of additional research, in addition to I don't similar interrogation beingness limited That said, it seems pretty clear to me equally someone who has never fired a gun in addition to tends to favor additional gun controls that most populace wellness researchers in addition to therefore in addition to forthwith take away keep been so stridently anti-gun that their interrogation was non trustworthy. I also tend to persuasion gun policy equally a social scientific discipline issue, which is best tackled alongside the social scientific discipline interrogation methods similar those considered inwards the RAND report. It's non clear to me that public wellness researchers take away keep the tools or expertise to address it appropriately.
