Research Says Psychopath Are Less Likely To Yawn From Contagiousness

(NEWSER) – A human behavior that's often contagious may provide a simple clue to whether a person is a psychopath, researchers from Baylor University have discovered, per Smithsonian. A study published in the Personality and Individual Differences journal finds that individuals with psychopathic traits—including coldheartedness, self-centered impulsivity, and "fearless dominance," per a press release—are less likely to "catch" a yawn from other people, an action that has suggested empathy and emotional connections with other people in past studies, Smithsonian explains. "I thought, 'If it's true that yawning is related to empathy, I'll bet that psychopaths yawn a lot less.' So I put it to the test," the study's lead author, Brian Rundle, says in the release. How he tested his hypothesis: After administering a psychological test to 135 students to see how they placed on the psychopath spectrum, his team applied electrodes to the subjects and placed them in front of computer screens that showed short clips of faces that were yawning, laughing, and neutral. The electrodes measured muscle and nerve reactions, plus how frequently subjects yawned. Researchers found the less empathy subjects had demonstrated on the test, the less likely they yawned. That doesn't mean if you don't catch a yawn, you're a psychopath, Rundle says. "The take-home lesson is not that if you yawn and someone else doesn't, the other person is a psychopath," he says in the release. "A lot of people didn't yawn, and we know that we're not very likely to yawn in response to a stranger we don't have empathetic connections with. … This is [just] a good starting point to ask more questions." (Yawning also gets less contagious as we age.)

Its 11:30 am and I’m yawning like a motherfucker cause i want to nap right now. Not saying that dispels any myth about my mental status but i don’t think Im crazy. And I don’t even think this study is crazy. It makes sense. I’ve been known to hate a lot. I compiled like a 15 page book comprised of this one person my buddy likes that i hate just to prove to him why i hate her. I had a list of people i despise when i have to be a delivery boy and deliver food to them. I hate a ton of people. But I’m not murdering in cold blood. See when you look into the eyes of like Joseph Kony or Putin. You can just see the hate in their eyes. Their brains constantly buzzing thinking about all the psychopath stuff they’re gonna do. It makes sense. If they were caught just in a crowded room yawning because someone below them is yawning it would undermine all authority. I picture a room full of people in a boring class yawning their balls off and theres just the kid in the back stewing his brain over someone he hates. No chance that psychopath fits into normal society and neither do his yawning habbits.
