The scale of gun violence in the United States is often measured by the aftermath—the sirens, the hospital admissions, and the final death tolls. But a novel study suggests that the crisis begins long before a trigger is pulled, rooted in a widespread, often invisible prevalence of homicidal ideation. According to researchers from the University of Michigan, millions of Americans have seriously considered using a firearm to kill another person, revealing a staggering gap between public perception and the psychological reality of the nation’s relationship with guns.
The findings, published in JAMA Network Open, indicate that approximately 7.3% of adults have contemplated killing someone with a firearm at some point in their lives. When extrapolated to the general population, this suggests that more than 19 million citizens have experienced these thoughts. This data shifts the conversation from the act of violence to the homicidal ideation in Americans, suggesting that the impulse toward lethal violence is far more common than previously understood by public health officials.
As a physician and medical writer, I have seen how public health often focuses on the “event”—the shooting or the injury—while overlooking the prodromal phase. The sheer volume of people harboring these thoughts suggests that firearm violence is not merely a criminal justice issue, but a profound psychiatric and systemic health crisis. With roughly 44,000 firearm-related deaths recorded in 2024, the bridge between a fleeting thought and a fatal action remains the most critical point for intervention.
The Anatomy of Lethal Intent
The study, which surveyed a panel of 7,000 adults between May and September 2025, distinguishes between general thoughts and active planning. While 7.3% had ever considered such an act, 3.3% of the population reported seriously nourishing a plan to kill someone within the past year alone. Most alarming is the finding that nearly 1% of respondents moved beyond ideation to action, reporting that they had traveled to a specific location with a weapon and the intent to kill.
The targets of these intentions vary, reflecting different types of societal and personal friction. The research identifies a clear hierarchy of who is most likely to be in the crosshairs of someone experiencing homicidal ideation:
- Personal Enemies: Over 50% of those with lethal intentions targeted individuals they defined as a personal enemy.
- Strangers: Nearly 25% of the intent was directed toward complete strangers, a finding that mirrors the randomness of mass casualty events.
- Government Officials: 14% of potential shooters targeted representatives of the government, signaling a dangerous trend of institutional distrust.
- Intimate Partners: Roughly 10% of respondents considered killing a current or former partner.
- Workplace Associates: 7% targeted colleagues or supervisors.
Risk Factors and the Myth of the “Typical” Shooter
One of the most significant contributions of this research is the dismantling of common stereotypes regarding who is most likely to harbor homicidal thoughts. Many believe that gun ownership itself is the primary driver of these thoughts, or that specific political affiliations are the leading indicators. However, the data suggests otherwise: neither owning a firearm nor belonging to a particular political party significantly increased the frequency of these homicidal thoughts.
Instead, the risk is more closely tied to sociodemographic markers. The profiles most prone to these fantasies of violence are young men, predominantly those living in urban environments with lower levels of formal education. This correlation suggests that the impulse toward violence is often a byproduct of systemic instability and social marginalization rather than a simple byproduct of weapon access.
| Category | Percentage of Population | Estimated Reach |
|---|---|---|
| Lifetime Consideration | 7.3% | ~19 Million |
| Serious Intent (Past Year) | 3.3% | ~8.5 Million |
| Attempted Action (Travelled to site) | ~1% | ~2.6 Million |
The Window for Prevention
Despite the grim nature of these statistics, the researchers emphasize that the transition from thought to action is rarely a silent process. There is often a “leakage” of intent—a period where the individual signals their distress or their plans to others. The study found that approximately 1.5% of Americans disclose their murderous intentions to people in their lives before attempting to act.
In some instances, these individuals exhibit a paradoxical desire for help, explicitly asking friends or family members to remove or confiscate their weapons because they feel a crisis of violence becoming uncontrollable. These moments represent a vital clinical and legal window for intervention.
This evidence provides a strong medical and public health argument for “Red Flag” laws (Extreme Risk Protection Orders). By allowing law enforcement and healthcare providers to temporarily remove firearms from individuals posing a danger to themselves or others, the system can interrupt the trajectory from ideation to homicide. When a person asks for their weapons to be taken away, it is a clear clinical signal of an acute crisis that requires immediate stabilization.

The next phase of this research will likely focus on the efficacy of community-based intervention programs and whether targeted mental health screenings in urban centers can reduce the prevalence of these lethal fantasies. As policymakers debate the legality of firearm ownership, the medical community is increasingly calling for a focus on the psychological precursors of violence to prevent tragedies before they reach the emergency room.
