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.

A Harvard professor's study discovers the worst year to be alive.
- Harvard professor Michael McCormick argues the worst year to be alive was 536 AD.
- The year was terrible due to cataclysmic eruptions that blocked out the sun and the spread of the plague.
- 536 ushered in the coldest decade in thousands of years and started a century of economic devastation.
The past year has been nothing but the worst in the lives of many people around the globe. A rampaging pandemic, dangerous political instability, weather catastrophes, and a profound change in lifestyle that most have never experienced or imagined.
But was it the worst year ever?
Nope. Not even close. In the eyes of the historian and archaeologist Michael McCormick, the absolute "worst year to be alive" was 536.
Why was 536 so bad? You could certainly argue that 1918, the last year of World War I when the Spanish Flu killed up to 100 million people around the world, was a terrible year by all accounts. 1349 could also be considered on this morbid list as the year when the Black Death wiped out half of Europe, with up to 20 million dead from the plague. Most of the years of World War II could probably lay claim to the "worst year" title as well. But 536 was in a category of its own, argues the historian.
It all began with an eruption...
According to McCormick, Professor of Medieval History at Harvard University, 536 was the precursor year to one of the worst periods of human history. It featured a volcanic eruption early in the year that took place in Iceland, as established by a study of a Swiss glacier carried out by McCormick and the glaciologist Paul Mayewski from the Climate Change Institute of The University of Maine (UM) in Orono.
The ash spewed out by the volcano likely led to a fog that brought an 18-month-long stretch of daytime darkness across Europe, the Middle East, and portions of Asia. As wrote the Byzantine historian Procopius, "For the sun gave forth its light without brightness, like the moon, during the whole year." He also recounted that it looked like the sun was always in eclipse.
Cassiodorus, a Roman politician of that time, wrote that the sun had a "bluish" color, the moon had no luster, and "seasons seem to be all jumbled up together." What's even creepier, he described, "We marvel to see no shadows of our bodies at noon."
...that led to famine...
The dark days also brought a period of coldness, with summer temperatures falling by 1.5° C. to 2.5° C. This started the coldest decade in the past 2300 years, reports Science, leading to the devastation of crops and worldwide hunger.
...and the fall of an empire
In 541, the bubonic plague added considerably to the world's misery. Spreading from the Roman port of Pelusium in Egypt, the so-called Plague of Justinian caused the deaths of up to one half of the population of the eastern Roman Empire. This, in turn, sped up its eventual collapse, writes McCormick.
Between the environmental cataclysms, with massive volcanic eruptions also in 540 and 547, and the devastation brought on by the plague, Europe was in for an economic downturn for nearly all of the next century, until 640 when silver mining gave it a boost.
Was that the worst time in history?
Of course, the absolute worst time in history depends on who you were and where you lived.
Native Americans can easily point to 1520, when smallpox, brought over by the Spanish, killed millions of indigenous people. By 1600, up to 90 percent of the population of the Americas (about 55 million people) was wiped out by various European pathogens.
Like all things, the grisly title of "worst year ever" comes down to historical perspective.
A machine learning system lets visitors at a Kandinsky exhibition hear the artwork.
Have you ever heard colors?
As part of a new exhibition, the worlds of culture and technology collide, bringing sound to the colors of abstract art pioneer Wassily Kandinsky.
Kandinsky had synesthesia, where looking at colors and shapes causes some with the condition to hear associated sounds. With the help of machine learning, virtual visitors to the Sounds Like Kandinsky exhibition, a partnership project by Centre Pompidou in Paris and Google Arts & Culture, can have an aural experience of his art.
An eye for music
Kandinsky's synesthesia is thought to have heavily influenced his painting. Seeing yellow summoned up trumpets, evoking emotions like cheekiness; reds produced violins portraying restlessness; while organs representing heavenliness he associated with blues, according to the exhibition notes.
Virtual visitors are invited to take part in an experiment called Play a Kandinsky, which allows them to see and hear the world through the artist's eyes.

In 1925, the artist's masterpiece, "Yellow, Red, Blue", broke new ground in the world of abstract art, guiding the viewer from left to right with shifting shapes and shades. Almost a century after it was painted, Google's interactive tool lets visitors click different parts of the artwork to journey through the artist's description of the colors, associated sounds and moods that inspired the work.
But Google's new toy is not the only tool developed to enhance the artistic experience.
Artist Neil Harbisson has developed an artificial way to emulate Kandinsky by turning colors into sounds. He has a rare form of color blindness and sees the world in greyscale. But a smart antenna attached to his head translates dominant colors into musical notes, creating a real-world soundtrack of what's in front of him. The invention could open up a new world for people who are color blind.
A new study suggests that private prisons hold prisoners for a longer period of time, wasting the cost savings that private prisons are supposed to provide over public ones.
- Private prisons in Mississippi tend to hold prisoners 90 days longer than public ones.
- The extra days eat up half of the expected cost savings of a private prison.
- The study leaves several open questions, such as what affect these extra days have on recidivism rates.
The United States of America, land of the free, is home to 5 percent of the world's population but 25 percent of its prisoners. The cost of having so many people in the penal system adds up to $80 billion per year, more than three times the budget for NASA. This massive system exploded in size relatively recently, with the prison population increasing by six-fold in the last four decades.
Ten percent of these prisoners are kept in private prisons, which are owned and operated for the sake of profit by contractors. In theory, these operations cost less than public prisons and jails, and states can save money by contracting them to incarcerate people. They have a long history in the United States and are used in many other countries as well.
However, despite the pervasiveness of private contractors in the American prison system, there is not much research into how well they live up to their promise to provide similar services at a lower cost to the state. The little research that is available often encounters difficulties in trying to compare the costs and benefits of facilities with vastly different operations and occasionally produces results suggesting there are few benefits to privatization.
A new study by Dr. Anita Mukherjee and published in the American Economic Journal: Economic Policy joins the debate with a robust consideration of the costs and benefits of private prisons. Its findings suggest that some private prisons keep people incarcerated longer and save less money than advertised.
The study focuses on prisons in Mississippi. Despite its comparatively high rate of incarceration, Mississippi's prison system is very similar to that of other states that also use private prisons. Demographically, its system is representative of the rest of the U.S. prison system, and its inmates are sentenced for similar amounts of time.
The state attempts to get the most out of its privatization efforts, as a 1994 law requires all contracts for private prisons in Mississippi to provide at least a 10 percent cost savings over public prisons while providing similar services. As a result, the state seeks to maximize its savings by sending prisoners to private institutions first if space if available.
While public and private prisons in Mississippi are quite similar, there are a few differences that allow for the possibility of cost savings by private operators — not the least of which is that the guards are paid 30 percent less and have fewer benefits than their publicly employed counterparts.
The results of privatization

The study relied on administrative records of the Mississippi prison system between 1996 and 2013. The data included information on prisoner demographics, the crimes committed, sentence lengths, time served, infractions while incarcerated, and prisoner relocation while in the system, including between public and private jails. For this study, the sample examined was limited to those serving between one and six years and those who served at least a quarter of their sentence. This created a primary sample of 26,563 bookings.
Analysis revealed that prisoners in private prisons were behind bars for four to seven percent longer than those in public prisons, which translates to roughly 85 to 90 extra days per prisoner. This is, in part, because those in private prison serve a greater portion of their sentences (73 percent) than those in public institutions (70 percent).
This in turn might be due to the much higher infraction rate in private prisons compared to public ones. While only 18 percent of prisoners in a public prison commit an infraction, such as disobeying a guard or possessing contraband, the number jumps to 46 percent in a private prison. Infractions can reduce the probability of early release or cause time to be added to a sentence.
It's unclear why there are so many more infractions in private prisons. Dr. Mukherjee suggests it could be the result of "harsher prison conditions in private prisons," better monitoring techniques, incentives to report more of them to the state before contract renewals, or even a lackadaisical attitude on the part of public prison employees.
What does all this cost Mississippi?
The extra time served eats 48 percent of the cost savings of keeping prisoners in a private facility. For example, it costs about $135,000 to house a prisoner in a private prison for three years and $150,000 in the public system. But longer stays in private prisons reduce the savings from $15,000 to only $7,800.
As Dr. Mukherjee remarks, this cost is also just the finance. Some things are a little harder to measure:
"There are, of course, other costs that are difficult to quantify — e.g., the cost of injustice to society (if private prison inmates systematically serve more time), the inmate's individual value of freedom, and impacts of the additional incarceration on future employment. Abrams and Rohlfs (2011) estimates a prisoner's value of freedom for 90 days at about $1,100 using experimental variation in bail setting. Mueller-Smith (2017) estimates that 90 days of marginal incarceration costs about $15,000 in reduced wages and increased reliance on welfare. If these social costs were to exceed $7,800 in the example stated, private prisons would no longer offer a bargain in terms of welfare-adjusted cost savings."
It is possible that the extra time in jail provides benefits that counter these costs, such as a reduced recidivism rate, but this proved difficult to determine. Though it was not statistically significant, there was some evidence that the added time actually increased the rate of recidivism. If that's true, then private prisons could be counterproductive.
