Premeditated horror
- In contrast to impulsive shooters, individuals like Eric Harris, Dylan Klebold, Seung-Hui Cho, Adam Lanza, and Nikolas Cruz meticulously planned their attacks. They reveled in the chaos they caused, showing no remorse for the devastation they inflicted.

The role of untreated mental illness
- Mental illness often amplifies the anger and resentment of mass shooters, making it harder to quell. A 2021 study of 50 US mass shooters from 1982 to 2019 revealed that approximately two-thirds had untreated psychiatric disorders.

Psychological patterns
- Research reveals that approximately 8% of mass shooters have autism spectrum disorder, a rate significantly higher than in the general population. Clinical depression, schizophrenia, paranoia, and narcissism are also common.

A misunderstood link
- While mental illness is often associated with mass shootings, researchers caution against placing sole blame on conditions like schizophrenia, autism, or depression, as millions face these challenges without resorting to violence.

The role of empathy and interaction
- "Through face-to-face engagement and mirroring, we connect with the minds and, literally, the hearts of others. When you catch another’s smile and smile yourself, you feel better," explains Schwartz.

A common thread among school shooters
- Schwartz’s research following the Sandy Hook tragedy reveals a striking pattern: nearly all mass shooters, particularly those targeting schools, experience intense social isolation. This detachment from society plays a critical role in their path to violence.

Screens vs. human connection
- Schwartz also expresses strong conviction that social media and screen time are increasingly replacing face-to-face interactions, further contributing to social isolation.

Decoding mass-shooter psychology
What we’ve learned since Columbine
© Getty Images
Most of us would rather not dwell on the idea of monsters, but they’re hard to banish from our minds. Our brains, shaped by millennia of evolution to detect danger, keep them vividly alive. In today’s world, mass shooters have replaced the primal threats that once haunted us: not lions in the brush or snakes in the grass, but killers in schools, grocery stores, and shopping malls.
These monsters don’t lurk in shadows: they strike in broad daylight, in places we consider safe. To protect ourselves and our communities, we must confront their motives, examine their mental anguish, and study their disordered minds. Only then can we begin to uncover ways to prevent these tragedies before they unfold.
Click through the gallery to explore the progress we’ve made and the hope it offers for a safer future.
