Writing of her future demise, author and humorist Dorothy Parker once observed that her epitaph might read, “Wherever she went, including here, it was against her better judgment.”

Celebrated for her scathing wit and wordplay, the late Parker might agree that sarcasm held tangible benefits. Doled out with care, ironic remarks—usually defined as communication that humorously conveys your intent through language that appears to be the opposite of what you mean—can amuse friends, lighten the mood, or broadcast your wit. But there’s more to sarcasm than simply eliciting a laugh. It turns out that the perks of your caustic muttering might have some scientific support. Take a look at a few peer-reviewed consequences to your snappy comebacks.

1. Sarcasm and humor might make you appear more confident, particularly at work.

In a 2016 paper published in the Journal of Personality and Social Psychology, researchers evaluated adults on their responses to some candid remarks about fictional pet food and travel companies, among other subjects. Those with zingers were perceived as having more competence and confidence. “The successful use of humor—telling jokes that are funny and appropriate—can raise your status because it makes you appear more confident and more competent,” says co-author Thomas Bitterly, a postdoctoral research fellow at the University of Michigan's Stephen M. Ross School of Business. “Confidence and competence are two of the key traits that determine whether we give someone status. The reason for this is because we want the individuals who have influence in a group to be those who are capable of leading it.”

Humor and sarcasm work to reinforce these traits, Bitterly tells Mental Floss, because humor itself is a risk. “Before we tell a joke, especially to people we do not know well, it’s difficult to know with certainty if our audience will find it funny and appropriate. If they find it unfunny and inappropriate, they will think that we lack competence and we will lose status. Given that humor is risky, telling a joke signals confidence,” he says.

2. Sarcasm can improve creativity.

In a 2015 paper [PDF] published in Organizational Behavior and Human Decision Processes, researchers (including those at Harvard and Columbia business schools) made the case for sarcasm facilitating creative thinking. In a series of experiments, participants gave or received positive, neutral, or sarcastic responses with a partner. Those in the sarcastic groups performed better at creative tasks—like problem-solving on paper—after the fact.

"This is because both sarcasm construction and sarcasm interpretation are conducive to abstract thinking, a key cognitive precursor to creative thinking," lead author Li Huang, an assistant professor of organizational behavior at INSEAD, tells Mental Floss. Huang points to a common sarcastic comment aimed at someone wasting time in the workplace: "Don't work too hard." The intended meaning is likely to "work harder." Both the speaker and recipient benefit, Huang says, because both need to process the underlying message. The speaker must translate the admonishment to sarcasm, and the recipient has to consider what the speaker really meant. That abstraction fosters creative thinking because creativity is needed to discern the truth and not the literal meaning of the statement.

"In this way, to construct or interpret sarcasm is to traverse the psychological distance between the stated and the intended meaning through abstract thinking," Huang says.

There is one word of caution: Sarcasm tends to have this effect when it’s lobbed between two parties who know and trust one another. With strangers, it might simply come off as rude or confusing.

3. Sarcasm can make criticism seem almost pleasant.

Want to offer some constructive commentary without feeling like a jerk? In a 2016 paper published in the Journal of Speech, Language, and Hearing Research, co-author Melanie Glenwright, an associate professor of psychology at the University of Manitoba, examined how adults and children interpreted sarcastic commentary. The generally agreeable reactions by adults to criticism indicates it can be wrapped in an amusing remark that reduces the chance for the listener to feel offended.

“The use of indirect language allows the speaker to criticize the addressee indirectly which is perceived as more polite than a direct, literal insult,” Glenwright tells Mental Floss. "Speakers may use sarcasm to deliver insults in professional or social settings where they want to criticize another person in a less-harsh manner.”

4. Sarcasm can make for better social bonding.

When we pass along a humorous observation and someone agrees with it, we’re strengthening our bond with that individual, according to Glenwright. “[Sarcasm] improves social bonding between the speaker and the addressee,” she says. “Sarcasm can also be used to convey humor and jocularity which can improve mood both in the speaker and addressee.”

5. Sarcasm might make you appear more intelligent.

Sarcasm and humor alike share a common trait: They require creative thinking that’s rapidly deployed to analyze a situation. Depending on the company, Bitterly says that a clever retort could potentially have people thinking more highly of you. “Saying something that is funny and appropriate is difficult,” he says. “It requires being able to recognize an opportunity for humor—'did someone just say something I know a funny response for'—[and] being able to quickly generate or recall a funny response and being able to predict how the audience is going to respond. On top of those things, delivery and timing also matter …. We tend to view people who manage to successfully pull off all of these things as being more intelligent, and we see that reflected in the way we refer to them.”

Sssspectacular: Tree Snakes in Australia Can Actually Jump

Ophidiophobia, or fear of snakes, is common among humans. We avoid snakes in the wild, have nightmares about snakes at night, and recoil at snakes on television. We might even be born with the aversion. When researchers showed babies photos of snakes and spiders, their tiny pupils dilated, indicating an arousal response to these ancestral threats.

If you really want to scare a baby, show them footage of an Australian tree snake. Thanks to researchers at Virginia Tech, we now know these non-venomous snakes of the genus Dendrelaphis can become airborne, propelling themselves around treetops like sentient Silly String.

That’s Dendrelaphis pictus, which was caught zipping through the air in 2010. After looking at footage previously filmed by her advisor Jake Socha, Virginia Tech Ph.D. candidate Michelle Graham headed for Australia and built a kind of American Ninja Warrior course for snakes out of PVC piping and tree branches. Graham observed that the snakes tend to spot their landing target, then spring upward. The momentum gets them across gaps that would otherwise not be practical to cross.

Graham next plans to investigate why snakes feel compelled to jump. They might feel a need to escape, or continue moving, or do it because they can. Two scientific papers due in 2020 could provide answers.

Dendrelaphis isn’t the only kind of snake with propulsive capabilities. The Chrysopelea genus includes five species found in Southeast Asia and China, among other places, that can glide through the air.

9 Facts About Narcolepsy

Everyone experiences occasional daytime sleepiness, but just a small fraction of the population knows what it’s like to have narcolepsy. The disorder is defined by persistent drowsiness throughout the day, and in some cases, sleep paralysis, hallucinations, and the sudden loss of muscle control known as cataplexy. Having narcolepsy can make doing everyday activities difficult or dangerous for patients, but unlike some chronic conditions, it’s also easy to diagnose and treat. Here are some facts you should know about the condition.

1. There are two types of narcolepsy.

If everything you know about narcolepsy comes from movies and TV, you may think of it as the disease that causes people to go limp without warning. Sudden loss of muscle control is called cataplexy, and it’s the defining symptom of type 1 narcolepsy. Type 2 narcolepsy, on the other hand, is mainly characterized by fatigue. Losing motor function while awake isn’t a problem for those with type 2.

2. Type 1 narcolepsy stems from a chemical deficiency.

Almost every patient with type 1 narcolepsy has low levels of hypocretin. Hypocretin is a neurochemical that regulates the wake-sleep cycle. When there isn’t enough of this chemical in the brain, people have trouble staying conscious and alert throughout the day. Most people with the second, less severe type of narcolepsy have normal hypocretin levels, with about a third of them producing low or undetectable amounts. Type 2 narcoplepsy has been studied far less than type 1 of the disorder, and scientists are still figuring out what causes it.

3. The exact causes of narcolepsy aren’t always clear.

So why do some people’s brains produce less hypocretin than others? That part has been hard for scientists to figure out. One possible explanation is that certain autoimmune disorders cause the body to attack the healthy brain cells that make this chemical. This disorder can be the result of genetic and environmental factors. Although people with narcolepsy rarely pass it down to their offspring (this happens less than 1 percent of the time), the sleep condition does occasionally crop up in family clusters, suggesting there is sometimes a genetic component at play. Head trauma that impacts the area of the brain responsible for governing sleep can also lead to narcolepsy in rare cases.

4. There are tests to diagnose narcolepsy.

If patients believe they might have narcolepsy, their doctors might ask them to detail their sleep history and keep a record of their sleep habits. There are also a few tests potential narcoleptics can take to determine if they have the condition. During a polysomnography test, patients spend the night at a medical facility with electrodes attached to their heads to monitor their breathing, eye movement, and brain activity. A multiple sleep latency test is similar, except it gauges how long it takes patients to fall asleep during the day.

5. Strong emotions can trigger cataplexy.

Cataplectic spells can sometimes be predicted by triggers. In some patients, feeling strong emotions—whether they’re crying, laughing, angry, or stressed—is all it takes for them to lose muscle control. These triggers vary from patient to patient, and they can even affect the same person randomly. Some people deal with them by avoiding certain situations and closing themselves off emotionally, which can disrupt their social lives.

6. Narcolepsy can make sleep terrifying.

Narcoleptics don’t just worry about their disorder during their waking hours. When they’re trying to fall asleep at night or wake up in the morning, narcolepsy can complicate things. One symptom is experiencing vivid, dream-like hallucinations while transitioning in or out of consciousness. These visions are often scary and may involve an intruder in the room with the sleeper. If they happen as the patient falls asleep, the hallucinations are called hypnagogic, and if they occur as they wake up, they’re hypnopompic.

A related symptom is sleep paralysis. This happens when a person’s brain cuts off muscle control of their body before they’re fully asleep or as they’re waking up. This combined with hypnagogic or hypnopompic nightmares can cause frightening experiences that are sometimes confused for real encounters.

7. Narcoleptics sometimes do activities half-asleep.

To outside observers, narcolepsy is sometimes hard to spot. A narcoleptic patient overcome by sleepiness won’t necessarily pass out in the middle of what they’re doing. Some act out “automatic behavior,” which means they continue with their actions—whether that’s walking, driving, or typing—with limited consciousness. This can cause poor performance at work or school, and in worst case scenarios, accidents while driving a car or operating machinery.

8. Harriet Tubman may have had narcolepsy.

One of the most famous likely narcoleptics in history is Harriet Tubman. The African American abolitionist was known to suffer from what were probably sudden narcoleptic episodes. The condition may have stemmed from the severe head trauma she sustained when a slave master threw an iron at another slave and hit her instead. The injury left her with permanent brain damage: In addition to narcolepsy, she also experienced chronic seizures and migraines throughout her life.

9. Medications and lifestyle changes are common narcolepsy treatments.

Though there’s no way to cure narcolepsy completely, there are many treatment options available. Taking medication is one of the most common ways to manage the disorder. Stimulants such as modafinil and armodafinil can be used to combat mild sleepiness, while amphetamines are often prescribed for more severe forms of fatigue. For hallucinations and sleep paralysis, selective serotonin reuptake inhibitors and serotonin and norepinephrine reuptake inhibitors—drugs that suppress REM sleep—can help.

As an alternative or supplementary treatment to medications, doctors may recommend lifestyle changes. Sticking to a sleep schedule, exercising regularly, avoiding nicotine and alcohol, and taking naps during the day can all reduce the symptoms of narcolepsy.
