156-430: A National Institute of Justice -funded project in which researchers studied every mass shooting since 1966, and approximately 150 mass shooters, and coded 50 life history variables for each. Their data suggest that almost all mass shooting perpetrators had four life history variables in common: they had (1) commonly experienced early childhood trauma and exposure to violence; (2) "reached an identifiable crisis point in

However, the study did find evidence that mass shootings "have polarizing effects conditional on partisanship": "That is, Democrats who live near a mass shooting even tend to become more supportive of gun control restrictions, while Republican attitudes shift in the opposite direction." The study authors concluded, "To
312-572: A 2016 study found that nearly one-third of the world's public mass shootings between 1966 and 2012 (90 of 292 incidents) occurred in the United States, In 2017 The New York Times recorded the same total of mass shootings for that span of years. A 2023 report published in JAMA covering 2014 to 2022, found there had been 4,011 mass shootings in the US, most frequent around the southeastern U.S. and Illinois. This

British criminologist Peter Squires argued that mass shooters in Europe and the U.S. "tend to be loners with not much social support who strike out at their communities, schools and families", and noted that countries with high gun-ownership rates but greater social capital (such as Norway , Finland , Switzerland , and Israel ) have fewer mass killings. Psychologist Jillian Peterson and James Densley co-founded The Violence Project,
546-497: A formal diagnosis of mental illness" and that only one-fourth of active shooters surveyed had a formal diagnosis of any mental health disorder (and a psychotic disorder in only 3 cases). The survey concludes that given the high lifetime prevalence of the symptoms of mental illness among the U.S. population, "formally diagnosed mental illness is not a very specific predictor of violence of any type, let alone targeted violence." The 2021 National Survey on Drug Use and Health conducted by

The study specifically found that "A 10% increase in state gun ownership was associated with a significant 35.1% (12.7% to 62.7%, P=0.001) higher rate of mass shootings. Partially adjusted regression analyses produced similar results, as did analyses restricted to domestic and non-domestic mass shootings." A 2020 study published in Law and Human Behavior examined

A panel of mental health and law enforcement experts has estimated that roughly one-third of acts of mass violence—defined as crimes in which four or more people were killed—since the 1990s were committed by people with a " serious mental illness " (SMI). However, the study emphasized that people with an SMI are responsible for less than 4% of all the violent acts committed in

In 2022, Psychology, Public Policy, and Law published a study by Jillian Peterson , James Densley , and others, assessing the life history variables of 172 mass shooters from 1966 to 2019. The researchers found that symptoms of psychosis played no role in 69% of mass shootings. In the October 2018 PLOS One study, the researchers studied whether state-level SMI rates predicted state-level mass shooting rates and found that state-level SMI rates did not predict state-level mass shooting rates. In 2004,

As of 2017, studies indicated that the rate at which public mass shootings occur has tripled since 2011. Between 1982 and 2011, a mass shooting occurred roughly once every 200 days. However, between 2011 and 2014, that rate has accelerated greatly with at least one mass shooting occurring every 64 days in

Mark Follman of Mother Jones , which compiles an open-source database of mass shootings, contends that "While all the victims are important, conflating those many other crimes with indiscriminate slaughter in public venues obscures our understanding of this complicated and growing problem." Northeastern University criminologist James Alan Fox argues against

A 2021 article in the journal Injury Epidemiology found that from 2014 to 2019, 59.1% of mass shootings in the United States were related to domestic violence (DV), and the shooter either killed a family member or had a DV history in 68.2% of mass shootings. Mass shooting contagion (the " copycat phenomenon ") has been studied. A study published in PLOS One in 2015 examined mass shootings in
1404-578: A single psychological profile and the characterization of mass shooters as "friendless loners" is a stereotype. Psychiatrist Paul S. Appelbaum argued that the data from the New York State Psychiatric Institute and Columbia University Irving Medical Center database of mass shootings show that "legal problems, substance and alcohol use, and difficulty coping with life events seem more useful foci for prevention [of mass shootings] and policy than an emphasis on serious mental illness."

1950-1046: The Journal of Threat Assessment and Management published a study comparing 171 public mass shooters and 63 active shooters in the United States from 1966 to 2019 (using cases compiled in The Violence Project's database) to the general population, homicide offenders , and people who die by suicide . In comparison to the general population, mass shooters were more likely to have a history of mental health issues, to have lifetime thought disorders , and greater lifetime suicidal ideation, while in comparison to general homicide offenders, mass shooters four times more frequently premeditated their homicides, eight times more frequently killed strangers, and were more likely to experience suicidal ideation and commit suicide directly or by cop . In comparison to people who committed suicide, mass shooters were actually more likely to have histories of suicidal ideation and were slightly more likely to premeditate

Researchers have found
2340-475: The October 2018 PLOS One study assessed the impact of state-level gun ownership rates in predicting state-level mass shooting rates and found that state-level gun ownership rates were not statistically significantly associated with the number of mass shootings in each state. The researchers tested the possibility that the relationship between gun ownership and the mass shooting rate was being confounded by gun law permissiveness and found that gun law permissiveness

Conversely, psychologist Peter F. Langman has argued that while mass shooters follow similar patterns, mass shooters do not fit
2730-447: The United States from 1976 to 2018. There is no fixed definition of a mass shooting in the United States, and different researchers define "mass shootings" in different ways.

In the December 2013 Journal of Forensic Sciences lone-actor terrorists survey, lone-actor attacks were rarely sudden or impulsive and the researchers have subsequently noted that a sizable subset of their subjects took preparations to maximize their chances of death by cop or suicide. Based upon the similarities in premeditation and lifetime suicidal ideation, James Densley has argued, "Many of these mass shootings are angry suicides." A 2021 cross-sectional study published in JAMA Network Open examining 170 perpetrators of mass public shootings from 1996 to 2019, found that 44% of mass shooters had leaked their plans prior to committing

"These findings suggest that leakage is a critical moment for mental health intervention to prevent gun violence." In 2015, psychiatrists James L. Knoll and George D. Annas noted that considering that mass shootings committed by perpetrators with SMIs amount to less than 1% of all gun-related homicides (and that most gun deaths in

The likelihood of them developing PTSD, depression, anxiety, suicidal thoughts, and more, are extraordinarily high. Studies show that 12.4% of mass shooting patients were diagnosed with some form of mental illness, most common being PTSD. Men show lower rates of developing PTSD unlike women who show higher rates. Men and women who fit
