Scientists Confirm 'Worst Person You Know' Is Actually Biologically Hardwired to Be That Way
WASHINGTON, D.C. — In a groundbreaking study that somehow got funded while the rest of us are eating gas station sushi for dinner, a team of behavioral geneticists from the National Institutes of Health has confirmed what literally anyone who’s ever worked retail already knew: some people are just born assholes.
The study, published this week in the journal *Nature Neuroscience*, claims to have identified a specific gene variant—dubbed the "HMP-7" or "Hold My Piss" sequence by the research team—that is directly linked to chronic entitlement, road rage, and the inexplicable urge to microwave fish in the office break room.
“For decades, we’ve blamed bad parenting, toxic masculinity, or a lack of third-grade reading comprehension for antisocial behavior,” said Dr. Emily Harrington, lead author of the study. “But our data suggests that for approximately 15% of the population, being an absolute menace to society is as inevitable as their next unpaid parking ticket.”
The research, which analyzed DNA samples from over 10,000 volunteers (and probably a few people who just spit into a tube for a free Amazon gift card), found that carriers of the HMP-7 variant show significantly reduced activity in the prefrontal cortex’s "basic human decency" region. This, apparently, is the same part of the brain responsible for not cutting in line, not blasting TikTok videos on public transit, and understanding that "No, you can’t speak to the manager about the fact that it’s raining."
Reddit, naturally, had a field day.
“So you’re telling me my ex-boyfriend, who once yelled at a barista for putting oat milk in his ‘extra oat milk latte,’ is actually genetically predisposed to being a human trash fire?” wrote u/SpilledMyMatcha in the r/science thread. “Cool, cool. So where do I file for retroactive emotional damages?”
Another user, u/ParkingLotEnforcer69, chimed in: “I work at a Home Depot. I’ve been saying this for years. It’s not ‘Karen’—it’s a genetic disorder. And we need to treat it accordingly. Namely, with a spray bottle and a timeout corner.”
The study’s methodology has already drawn some side-eye from the scientific community, mostly because it relies heavily on self-reported "jerk behavior" surveys. Critics argue that people who are actually terrible probably just lied on the questionnaire, which is—ironically—the most asshole move of all.
“The problem with studying jerks is that jerks don’t think they’re jerks,” said Dr. Marcus Webb, a sociologist at Stanford who was not involved in the study. “If you ask someone, ‘On a scale of 1 to 10, how much do you enjoy making the checkout line take 15% longer for everyone else,’ they’re not going to say ‘9.’ They’re going to say ‘I’m just being efficient.’ You can’t DNA-test your way out of self-awareness.”
But the NIH team stands by their data. They even identified a secondary marker, the "SMP-2" or "Screaming Into The Void" variant, which is strongly correlated with people who honk their car horn the *instant* a traffic light turns green. You know who you are. Yes, you, in the lifted Ford F-250 with the Punisher sticker. We see you.
So where does this leave the rest of us—the 85% of normies who just want to buy a sandwich without having a full-blown psychological warfare campaign launched against us by someone who thinks "customer is always right" is a constitutional amendment?
According to the study, there are treatments. Deep brain stimulation, targeted gene therapy, and—for the truly unhinged—daily mandatory viewings of the "Try Not to Cringe Challenge" compilation on YouTube. But the most effective intervention, researchers say, is simply "not engaging."
“If you see someone with the HMP-7 variant, the best thing you can do is not feed the beast,” Dr. Harrington warned. “They thrive on conflict. They are, in a very real sense, emotional vampires. And they probably don’t even own a proper recycling bin.”
The internet, predictably, has already weaponized this information. Several dating apps have reported a surge in users adding "HMP-7 Negative" to their bios, right between "fluent in sarcasm" and "looking for a third for a threesome." Meanwhile, the subreddit r/AITA is facing an existential crisis, as commenters are now split between "YTA, obviously" and "NTA, you can’t help being a genetic dumpster fire."
For their part, the researchers are already planning a follow-up study on whether the "I’m Not a Jerk, I’m Just Brutally Honest" personality type is actually just a milder form of sociopathy. Early results are promising, and by "promising," they mean "alarming."
One thing is clear: we are living in a post-accountability society. The next time your cousin Dave starts a political argument at Thanksgiving, you can just shrug and say, "Sorry, Dave, that’s just your HMP-7 talking." And then probably get uninvited from next year’s dinner.
But hey, at least now we know why the self-checkout line is always broken.
Final Thoughts
After decades of covering the quiet revolutions in labs and the loud noise of public misunderstanding, one truth stands out: we’ve mythologized the scientist as a lone genius in a white coat, when the real work is a grind of collaboration, failure, and incremental progress. The article reminds us that this gritty, human process is not a weakness to be hidden but the very engine of discovery, and dismissing it erodes the trust science needs to survive. Ultimately, our job isn’t to worship the results, but to respect the messy, skeptical method that produced them—because that’s the only way to keep the lights on in the dark.
