What drives mass shooters? Grievance, despair, and anger are more likely triggers than mental illness, experts say

A 2018 study by the FBI’s Behavioral Analysis Unit evaluating 63 active shooters between 2000 and 2013 found that a quarter were known to have been diagnosed with any kind of mental illness, and just 3 of the 63 had a verified psychotic disorder.

Although 62 percent of shooters showed signs that they were struggling with issues like depression, anxiety, or paranoia, their symptoms, the study notes, may ultimately have been “transient manifestations of behaviors and moods” that would not qualify them for a formal diagnosis.

Formally diagnosed mental illness, the study concludes, “is not a very specific predictor of violence of any type, let alone targeted violence,” given that roughly half of the US population experiences symptoms of mental illness over the course of their lifetimes.

Forensic psychologist Jillian Peterson, cofounder of The Violence Project, a think tank dedicated to reducing violence, said mass shooters are typically younger men, channeling their pain and anger through acts of violence and aggression. For many mass shooters, Peterson said, their path to violence begins with early childhood trauma. They often share a sense of “entitlement,” she said — to wealth, power, romance, and success. When they don’t achieve those goals, they become enraged and search for a scapegoat.

”As they get older, you see a lot of despair, hopelessness, self-hate — many of them attempt suicide — isolation. And then that kind of despair, isolation, that self-hatred turns outward,” Peterson said. “School shooters blame their schools. Some people blame a racial group or women or a religious group or the workplace.”

But mental illness, she said, is rarely an exclusive motive for mass shooters. In a study published last year, Peterson and her colleagues analyzed a dataset of 172 mass shooters for signs of psychosis — features of schizophrenia and other mood disorders. Although mental illness and psychotic disorders were overrepresented among the mass shooters they studied, Peterson’s study found most mass shooters were motivated by other factors, such as interpersonal conflicts, relationship problems, or a desire for fame.

Peterson’s study found psychotic symptoms, such as delusions or hallucinations, played no role in almost 70 percent of cases, and only a minor role in 11 percent of cases, where the shooters had other motives. In just 10 percent of cases, perpetrators were directly responding to their delusions or hallucinations when they were planning and committing their attacks.

Stop Blaming Mental Illness

The United States is experiencing a public health epidemic of mass shootings and other forms of gun violence. A convenient response seems to be blaming mental illness; after all, “who in their right mind would do this?” This is utterly wrong. Mental illnesses, certainly severe mental illnesses, are not the major cause of mass shootings. It also is dangerously stigmatizing to people who suffer from these devastating disorders and can subject them to inappropriate restrictions. According to the National Council for Behavioral Health, the best estimates are that individuals with mental illnesses are responsible for less than 4% of all violent crimes in the United States, and less than a third of people who commit mass shootings are diagnosably mentally ill. Moreover, a large majority of individuals with mental illnesses are not at high risk for committing violent acts. Continuing to blame mental illness distracts from finding the real causes of mass shootings and addressing them directly.

Mental illness is, regrettably, a rather loosely defined and loosely used term, and this contributes to the problem. According to the American Psychiatric Association, “Mental illnesses are health conditions involving changes in emotion, thinking or behavior…associated with distress and/or problems functioning in social, work or family activities.” That broad definition can arguably be applied to many life stresses and situations. However, what most people likely mean when they attribute mass shootings to mental illness are what mental health professionals call “serious or severe mental illnesses,” such as schizophrenia, bipolar disorder, or major depression. Other frequently cited causes of mass shootings—hate, employee disgruntlement, being disaffected with society or disappointed with one's life—are not defined clinically as serious mental illnesses themselves. And because they have not been studied systematically, we do not know if these purported other causes really apply, let alone what to do about them if true.

Cruel, Immoral Behavior Is Not Mental Illness

Here is an excerpt:

Another way of posing the question is to ask—Does immoral, callous, cruel, and supremely selfish behaviors constitute a mental illness? These socially deviant traits appear in those with and without mental illness, and are widespread in the general population. Are there some perpetrators suffering from a genuine psychotic disorder who remain mentally organized enough to carry out these attacks? Of course, but they are a minority. To further complicate matters, psychotic individuals can also commit violent acts that were motivated by base emotions (resentment, selfishness, etc.), while their psychotic symptoms may be peripheral or merely coincidental.

It bears repeating that reliable, clinically-based data or complete psychological autopsies on perpetrators of mass public shootings are very difficult to obtain. That said, some of the best available research on mass public shooters indicates that they often display “rigidness, hostility, or extreme self-centeredness.” A recent FBI study found that only 25% of mass shooters had ever had a mental illness diagnosis, and only 3 of these individuals had a diagnosis of a psychotic disorder. The FBI’s cautionary statement in this report is incisive: “. . . formally diagnosed mental illness is not a very specific predictor of violence of any type, let alone targeted violence…. declarations that all active shooters must simply be mentally ill are misleading and unhelpful."

Psychiatric and mental health treatment has its limits, and is not traditionally designed to detect and uncover budding violent extremists. It is designed to work together with individuals who are invested in their own mental health and seek to increase their own degrees of freedom in life in a pro-social manner. This is why calls for more mental health laws or alterations in civil commitment laws are likely to be low-yield at best, with respect to preventing mass killing—and stagnating to mental health progress at worst.

Misguided mental health system needs an overhaul

The glaring failures surrounding Esteban Santiago, resulting in the tragic killing of five people and wounding of eight others in Fort Lauderdale, Florida, prompts me to make some points about our misguided mental health system.

First, psychiatrists have no ability to predict who is going to be violent. In a Jan. 3, 2013, Washington Post article, "Predicting violence is a work in progress," after reviewing the research, writer David Brown, reported:

• "There is no instrument that is specifically useful or validated for identifying potential school shooters or mass murderers."

• "The best-known attempt to measure violence in mental patients found that mental illness by itself didn't predict an above-average risk of being violent."

• "(S)tudies have shown psychiatrists' accuracy in identifying patients who would become violent was slightly better than chance."

• "(T)he presence of a mental disorder (is) only a small contributor to risk, outweighed by other factors such as age, previous violent acts, alcohol use, impulsivity, gang membership and lack of family support."

Top 10 myths about mass shootings

By James Alan Fox

Originally published on December 19, 2012

Myth: Mass shootings are on the rise.

Reality: Over the past three decades, there has been an average of 20 mass shootings a year in the United States, each with at least four victims killed by gunfire. Occasionally, and mostly by sheer coincidence, several episodes have been clustered closely in time. Over all, however, there has not been an upward trajectory. To the contrary, the real growth has been in the style and pervasiveness of news-media coverage, thanks in large part to technological advances in reporting.

Myth: Mass murderers snap and kill indiscriminately.

Reality: Mass murderers typically plan their assaults for days, weeks, or months. They are deliberate in preparing their missions and determined to follow through, no matter what impediments are placed in their path.

Myth: Enhanced background checks will keep dangerous weapons out of the hands of these madmen.

Reality: Most mass murderers do not have criminal records or a history of psychiatric hospitalization. They would not be disqualified from purchasing their weapons legally. Certainly, people cannot be denied their Second Amendment rights just because they look strange or act in an odd manner. Besides, mass killers could always find an alternative way of securing the needed weaponry, even if they had to steal from family members or friends.

Myth: Restoring the federal ban on assault weapons will prevent these horrible crimes.

Reality: The overwhelming majority of mass murderers use firearms that would not be restricted by an assault-weapons ban. In fact, semiautomatic handguns are far more prevalent in mass shootings. Of course, limiting the size of ammunition clips would at least force a gunman to pause to reload or switch weapons.

Myth: Greater attention and response to the telltale warning signs will allow us to identify would-be mass killers before they act.

Reality: While there are some common features in the profile of a mass murderer (depression, resentment, social isolation, tendency to blame others for their misfortunes, fascination with violence, and interest in weaponry), those characteristics are all fairly prevalent in the general population. Any attempt to predict would produce many false positives. Actually, the telltale warning signs come into clear focus only after the deadly deed.

Myth: Widening the availability of mental-health services and reducing the stigma associated with mental illness will allow unstable individuals to get the treatment they need.

Reality: With their tendency to externalize blame and see themselves as victims of mistreatment, mass murderers perceive the problem to be in others, not themselves. They would generally resist attempts to encourage them to seek help. And, besides, our constant references to mass murderers as “wackos” or “sickos” don’t do much to destigmatize the mentally ill.

Myth: Increasing security in schools and other places will deter mass murder.

Reality: Most security measures will serve only as a minor inconvenience for those who are dead set on mass murder. If anything, excessive security and a fortress-like environment serve as a constant reminder of danger and vulnerability.

Myth: Students need to be prepared for the worst by participating in lockdown drills.

Reality: Lockdown drills can be very traumatizing, especially for young children. Also, it is questionable whether they would recall those lessons amid the hysteria associated with an actual shooting. The faculty and staff need to be adequately trained, and the kids just advised to listen to instructions. Schools should take the same low-key approach to the unlikely event of a shooting as the airlines do to the unlikely event of a crash. Passengers aren’t drilled in evacuation procedures but can assume the crew is sufficiently trained.

Myth: Expanding “right to carry” provisions will deter mass killers or at least stop them in their tracks and reduce the body counts.

Reality: Mass killers are often described by surviving witnesses as being relaxed and calm during their rampages, owing to their level of planning. In contrast, the rest of us are taken by surprise and respond frantically. A sudden and wild shootout involving the assailant and citizens armed with concealed weapons would potentially catch countless innocent victims in the crossfire.

Myth: We just need to enforce existing gun laws as well as increase the threat of the death penalty.

Reality: Mass killers typically expect to die, usually by their own hand or else by first responders. Nothing in the way of prosecution or punishment would divert them from their missions. They are ready to leave their miserable existence, but want some payback first.
