A new Harvard-backed study claims that mass shootings kill people who were never anywhere near the gunfire — through a spike in fatal car crashes tied to phone alerts and breaking-news distraction.
Quick Take
- A JAMA Psychiatry study found traffic deaths rose 14.3% nationwide the day after the ten deadliest U.S. mass shootings, about 20 extra deaths.
- Researchers used real fatal-crash data from 2008 to 2023, not guesswork or polling.
- The spike happened even in states far from the shooting, matching the peak in online searches about the attack.
- Nonfatal active-shooter events showed no such spike, suggesting public attention, not violence alone, drives the pattern.
- The study admits it cannot prove cause and effect, only a strong statistical link.
What The Study Actually Found
Researchers from Harvard Medical School compared the ten days before each major mass shooting with the day right after it. They found fatal crashes rose by an average of 14.3% nationwide following the ten deadliest shootings between 2008 and 2023, translating to roughly 20 additional deaths. That figure came from the Fatality Analysis Reporting System, a federal registry of every fatal traffic accident in the country, giving the finding a solid data foundation.
The increase was not confined to the town or state where the shooting happened. Phys.org reports the effect held true “even in states far away from the tragedy,” and researchers say it stayed consistent no matter the driver’s age, gender, location, or the weather that day. That nationwide reach is what makes the finding hard to write off as a local traffic jam or road-closure fluke.
Phones, Panic, And Distracted Driving
The study’s lead author, Anam Jena, offered a simple explanation many parents already suspect: notifications. “You’re driving, getting notifications on your phone, encountering numerous breaking alerts, and receiving calls — you are genuinely distracted,” he said. The traffic spike lined up almost exactly with the moment internet searches about the shooting hit their peak, tying the crash data directly to the media frenzy that follows every mass shooting.
Notably, the spike did not appear after active-shooter incidents where nobody died. Those events got far less news coverage, and researchers found no rise in traffic deaths afterward. That contrast points squarely at saturation media coverage and phone-buzzing panic, not gun violence broadly, as the trigger. For conservatives who have long argued the media turns tragedy into a 24-hour spectacle, this is hard data backing that instinct.
Correlation, Not Proof, And Why That Matters
Even the researchers behind the study caution against overselling it. Multiple outlets covering the findings note the research “does not establish a definitive cause-and-effect relationship”. The headline number is also built entirely on the ten single deadliest shootings, a narrow slice of a much larger problem, and the public summaries don’t reveal the full model, sample size, or whether holidays and weather were properly ruled out.

That gap matters. Anti-gun activists will be tempted to fold this study into arguments for more federal restrictions on lawful gun owners, when the actual mechanism described here is about distracted driving and media hysteria, not firearms themselves. The honest reading is that non-stop news alerts and phone notifications are dangerous behind the wheel — a personal-responsibility problem, not a Second Amendment problem.
The Real Takeaway For Families
The lesson conservatives should draw is straightforward: turn off the phone, pull over if you need to check the news, and don’t let a breaking-alert culture built for clicks put your family at risk on the highway. Government can’t legislate away grief or distraction, but personal discipline behind the wheel can prevent the kind of secondary tragedy this study describes. That’s a solution rooted in individual responsibility, not another excuse for Washington to expand its reach.
