Wise people are less lonely. Here's why.
America might be in the throes of a loneliness epidemic, but cultivating wisdom can help.
- Loneliness can seriously damage your mental and physical health and can even impact cognition and lifespan. What's worse, it's on the rise.
- Most research on the topic has focused on the negative impact of loneliness.
- Now, new research suggests that the wiser one is, the less lonely one feels, regardless of how many social connections one has.
While he was scraping out a life in the woods by Walden Pond, Henry David Thoreau wrote, "I find it wholesome to be alone the greater part of the time. To be in company, even with the best, is soon wearisome and dissipating. I love to be alone. I never found the companion that was so companionable as solitude."
Many would disagree — living in solitude can be seriously taxing for social animals like human beings. Even Thoreau, famous for his self-imposed solitude, needed people in his life; Thoreau's mother made weekly visits to give him food and do his laundry for him.
Although he may not have been a perfect representation of his own philosophy of self-reliance and solitude, Thoreau was an innovative thinker and better equipped to tolerate solitude than your average man. Now, new research has helped clarify the connection between wisdom and the ability to withstand loneliness. On December 18, Dr. Dilip Jeste at the University of California, San Diego, along with his colleagues, published a study in International Psychogeriatrics in which they found that the wiser one gets, the less lonely one feels.
A loneliness epidemic
The United States has been in the throes of a loneliness epidemic. In the last 50 years, self-reported rates of loneliness have doubled, which is bad news for public health. Loneliness can cause depression, substance abuse, cognitive impairment, malnutrition, frailty, poor sleep, and slew of other undesirable effects. Loneliness is so bad for you, in fact, that former Surgeon General Vivek McCarthy said that it is associated with a lifespan "as severe as the lifespan you see with smoking 15 cigarettes a day."
Considering how dangerous loneliness is and its rise, research on the phenomenon is desperately needed. This is why Jeste and colleagues conducted a study on 340 San Diegans to learn more about loneliness and what, if anything, can defend against it.
Defining loneliness and wisdom
In an interview with CNN, Jeste said, "One thing to remember is that loneliness is subjective. Loneliness does not mean being alone; loneliness does not mean not having friends. […] Loneliness is defined as 'subjective distress.'" Essentially, it is the perceived gap between the relationships you have and the ones you want.
While we know quite a bit about the nature of loneliness, less research has been done on the connection between loneliness and wisdom. Investigating this link made sense. In addition to the anecdotal evidence of the resilience of wise individuals against loneliness, more rigorous studies suggest that the nature of wisdom is very much opposed to loneliness. According to Jeste,
Published studies including literature reviews, an expert consensus panel, and examination of an ancient scripture suggest that wisdom is a complex human trait with specific components — i.e., emotional regulation, self-reflection, pro-social behaviors such as empathy and compassion, decisiveness, social advising, tolerance of divergent values, and spirituality.
Loneliness peaks at three key ages
Using a series of validated survey instruments to measure loneliness, mental and physical health, and wisdom, Jeste and his colleagues examined loneliness and wisdom in a sample whose ages ranged from 27 to 101.
The results were not encouraging. Roughly 76 percent of the sample reported feeling moderate to severe loneliness, and the lonelier a participant was, the more likely they were to experience poor mental and physical health and poor cognition.
The researchers also found an unusual relationship between loneliness and age. There were three peaks in loneliness: one in people's late twenties, one in the mid-fifties, and one in the late eighties. Although the study was not designed to explain these results, Jeste offered some speculation: "So the late 20s is often a period of major decision-making, which is often stressful because you often end up feeling that your peers made better decisions than you did, and there's a lot of guilt about why you did this or did that."
In your mid-fifties, "You see some of your friends are dying, and really, it's the first time you realize that your life span is not forever." And, of course, in one's late eighties, good friends have or will soon pass away, the end of life is approaching, and financial difficulties may add more stress to an already stressful time.
A silver lining
Using two survey instruments (the UCLA-3 loneliness survey and the SD-WISE wisdom survey), the researchers found that loneliness and wisdom had an inverse relationship. Image source: Jeste et al., 2018
But there was an optimistic finding: The wiser a participant was, the less likely they were to feel the kind of oppressive loneliness that can be so detrimental to one's health. The researchers measured wisdom through six essential aspects: altruism, a sense of fairness, insight, general knowledge of life, the management of emotions, acceptance of divergent values, and decisiveness.
According to the research, it seems that, because they cultivate relationships with themselves as much as they do with others, wise individuals tend to be in good company — whether or not they are surrounded by friends.
The natural follow-up question to this research is how to cultivate wisdom. Unfortunately, there are many, many answers to this question that are pseudoscientific at worst or poorly researched at best. The concept of wisdom, too, is difficult to define and represents a broad range of pro-social behaviors. However, based on the definition used in this study, if we become more introspective, learn to regulate our emotions, and cultivate empathy for others, we might just find our lives become a little less lonely.

So much for rest in peace.
- Australian scientists found that bodies kept moving for 17 months after being pronounced dead.
- Researchers used photography capture technology in 30-minute intervals every day to capture the movement.
- This study could help better identify time of death.
We're learning more new things about death everyday. Much has been said and theorized about the great divide between life and the Great Beyond. While everyone and every culture has their own philosophies and unique ideas on the subject, we're beginning to learn a lot of new scientific facts about the deceased corporeal form.
An Australian scientist has found that human bodies move for more than a year after being pronounced dead. These findings could have implications for fields as diverse as pathology to criminology.
Dead bodies keep moving
Researcher Alyson Wilson studied and photographed the movements of corpses over a 17 month timeframe. She recently told Agence France Presse about the shocking details of her discovery.
Reportedly, she and her team focused a camera for 17 months at the Australian Facility for Taphonomic Experimental Research (AFTER), taking images of a corpse every 30 minutes during the day. For the entire 17 month duration, the corpse continually moved.
"What we found was that the arms were significantly moving, so that arms that started off down beside the body ended up out to the side of the body," Wilson said.
The researchers mostly expected some kind of movement during the very early stages of decomposition, but Wilson further explained that their continual movement completely surprised the team:
"We think the movements relate to the process of decomposition, as the body mummifies and the ligaments dry out."
During one of the studies, arms that had been next to the body eventually ended up akimbo on their side.
The team's subject was one of the bodies stored at the "body farm," which sits on the outskirts of Sydney. (Wilson took a flight every month to check in on the cadaver.)Her findings were recently published in the journal, Forensic Science International: Synergy.
Implications of the study
The researchers believe that understanding these after death movements and decomposition rate could help better estimate the time of death. Police for example could benefit from this as they'd be able to give a timeframe to missing persons and link that up with an unidentified corpse. According to the team:
"Understanding decomposition rates for a human donor in the Australian environment is important for police, forensic anthropologists, and pathologists for the estimation of PMI to assist with the identification of unknown victims, as well as the investigation of criminal activity."
While scientists haven't found any evidence of necromancy. . . the discovery remains a curious new understanding about what happens with the body after we die.
Metal-like materials have been discovered in a very strange place.
- Bristle worms are odd-looking, spiky, segmented worms with super-strong jaws.
- Researchers have discovered that the jaws contain metal.
- It appears that biological processes could one day be used to manufacture metals.
The bristle worm, also known as polychaetes, has been around for an estimated 500 million years. Scientists believe that the super-resilient species has survived five mass extinctions, and there are some 10,000 species of them.
Be glad if you haven't encountered a bristle worm. Getting stung by one is an extremely itchy affair, as people who own saltwater aquariums can tell you after they've accidentally touched a bristle worm that hitchhiked into a tank aboard a live rock.
Bristle worms are typically one to six inches long when found in a tank, but capable of growing up to 24 inches long. All polychaetes have a segmented body, with each segment possessing a pair of legs, or parapodia, with tiny bristles. ("Polychaeate" is Greek for "much hair.") The parapodia and its bristles can shoot outward to snag prey, which is then transferred to a bristle worm's eversible mouth.
The jaws of one bristle worm — Platynereis dumerilii — are super-tough, virtually unbreakable. It turns out, according to a new study from researchers at the Technical University of Vienna, this strength is due to metal atoms.
Metals, not minerals

This is pretty unusual. The study's senior author Christian Hellmich explains: "The materials that vertebrates are made of are well researched. Bones, for example, are very hierarchically structured: There are organic and mineral parts, tiny structures are combined to form larger structures, which in turn form even larger structures."
The bristle worm jaw, by contrast, replaces the minerals from which other creatures' bones are built with atoms of magnesium and zinc arranged in a super-strong structure. It's this structure that is key. "On its own," he says, "the fact that there are metal atoms in the bristle worm jaw does not explain its excellent material properties."
Just deformable enough

What makes conventional metal so strong is not just its atoms but the interactions between the atoms and the ways in which they slide against each other. The sliding allows for a small amount of elastoplastic deformation when pressure is applied, endowing metals with just enough malleability not to break, crack, or shatter.
Co-author Florian Raible of Max Perutz Labs surmises, "The construction principle that has made bristle worm jaws so successful apparently originated about 500 million years ago."
Raible explains, "The metal ions are incorporated directly into the protein chains and then ensure that different protein chains are held together." This leads to the creation of three-dimensional shapes the bristle worm can pack together into a structure that's just malleable enough to withstand a significant amount of force.
"It is precisely this combination," says the study's lead author Luis Zelaya-Lainez, "of high strength and deformability that is normally characteristic of metals.
So the bristle worm jaw is both metal-like and yet not. As Zelaya-Lainez puts it, "Here we are dealing with a completely different material, but interestingly, the metal atoms still provide strength and deformability there, just like in a piece of metal."
Observing the creation of a metal-like material from biological processes is a bit of a surprise and may suggest new approaches to materials development. "Biology could serve as inspiration here," says Hellmich, "for completely new kinds of materials. Perhaps it is even possible to produce high-performance materials in a biological way — much more efficiently and environmentally friendly than we manage today."
Dealing with rudeness can nudge you toward cognitive errors.
- Anchoring is a common bias that makes people fixate on one piece of data.
- A study showed that those who experienced rudeness were more likely to anchor themselves to bad data.
- In some simulations with medical students, this effect led to higher mortality rates.
Cognitive biases are funny little things. Everyone has them, nobody likes to admit it, and they can range from minor to severe depending on the situation. Biases can be influenced by factors as subtle as our mood or various personality traits.
A new study soon to be published in the Journal of Applied Psychology suggests that experiencing rudeness can be added to the list. More disturbingly, the study's findings suggest that it is a strong enough effect to impact how medical professionals diagnose patients.
Life hack: don't be rude to your doctor
The team of researchers behind the project tested to see if participants could be influenced by the common anchoring bias, defined by the researchers as "the tendency to rely too heavily or fixate on one piece of information when making judgments and decisions." Most people have experienced it. One of its more common forms involves being given a particular value, say in negotiations on price, which then becomes the center of reasoning even when reason would suggest that number should be ignored.
It can also pop up in medicine. As co-author Dr. Trevor Foulk explains, "If you go into the doctor and say 'I think I'm having a heart attack,' that can become an anchor and the doctor may get fixated on that diagnosis, even if you're just having indigestion. If doctors don't move off anchors enough, they'll start treating the wrong thing."
Lots of things can make somebody more or less likely to anchor themselves to an idea. The authors of the study, who have several papers on the effects of rudeness, decided to see if that could also cause people to stumble into cognitive errors. Past research suggested that exposure to rudeness can limit people's perspective — perhaps anchoring them.
In the first version of the study, medical students were given a hypothetical patient to treat and access to information on their condition alongside an (incorrect) suggestion on what the condition was. This served as the anchor. In some versions of the tests, the students overheard two doctors arguing rudely before diagnosing the patient. Later variations switched the diagnosis test for business negotiations or workplace tasks while maintaining the exposure to rudeness.
Across all iterations of the test, those exposed to rudeness were more likely to anchor themselves to the initial, incorrect suggestion despite the availability of evidence against it. This was less significant for study participants who scored higher on a test of how wide of a perspective they tended to have. The disposition of these participants, who answered in the affirmative to questions like, "Before criticizing somebody, I try to imagine how I would feel if I were in his/her place," was able to effectively negate the narrowing effects of rudeness.
What this means for you and your healthcare
The effects of anchoring when a medical diagnosis is on the line can be substantial. Dr. Foulk explains that, in some simulations, exposure to rudeness can raise the mortality rate as doctors fixate on the wrong problems.
The authors of the study suggest that managers take a keener interest in ensuring civility in workplaces and giving employees the tools they need to avoid judgment errors after dealing with rudeness. These steps could help prevent anchoring.
Also, you might consider being nicer to people.
