James' World 2

Five hundred years ago, writing in The Prince, Nicolo Machiavelli offered advice to leaders trying to grow their power. “It would serve [the Prince] to appear pious, faithful, humane, true, religious, and even to be so,” he wrote, “but only if he is willing, should it become necessary, to act in the opposite manner.”

In other words, don’t hold on tightly to your values, because no one else will either.

Centuries later, that passage still perfectly encapsulates a cynical world view. Cynics believe that human beings are fundamentally self-interested. This also means that interactions between people are at their core a ruthless, Darwinian struggle for survival, where the path to success requires stepping past, over, or on the people around you.

Many of us follow this bleak logic. More than half of parents believe that to succeed, their children should think of the world as harsh and dangerous. According to the legendary management professor Sumantra Goshal, MBA students are taught that “companies must compete not only with their competitors but also with their suppliers, employees, and regulators.” In Silicon Valley, where I work, brilliant but toxic leaders such as Steve Jobs are celebrated and — too often — emulated.

Following Machiavelli’s advice, cynics sacrifice relationships and principle to win. Instead, research demonstrates they lose. A wave of new behavioral science has found that, over the course of one’s career, cynical thinking stands in the way of success. Parents might think their kids will thrive if they see the world as competitive, but people with that mindset earn less money and report lower satisfaction at work.

Other research follows people over time, testing their cynicism at one point and following up years later to measure professional outcomes. The news here is clearer, and even worse for cynics. Over a decade-long span, their salary grows at barely a third the rate of non-cynics, and they are less likely to be elevated to leadership positions.

Why? Compared to their more trusting counterparts, cynics report a greater hunger for power and pursue it in different ways. Confident that others will take advantage of them if given the chance, they go on the offensive, manipulating others first. Machiavelli would be proud. He urges leaders to dominate others, preferring to be feared than loved. Researchdoes find that dominant actions, such as intimidating coworkers and kissing up to higher-ups, tend to build people’s power in the workplace. But so do communal actions, such as sharing generously with colleagues. Research on disagreeable people who share cynics’ competitive streak finds that they use only dominant strategies to get ahead. This leaves them isolated and eventually puts a ceiling on their success.

Put simply, cynics are playing the wrong game. Success is not a winner-take-all battle royale. People most often win by building trusting connections and alliances. And even if an individual manages to shove their way to the top, their team often pays the price. Psychologists recently analyzed levels of narcissism in NBA players’ tweets and found that teams with higher levels of narcissism won fewer games. Why? To compete at the highest level, teammates must first stop trying to outdo each other. If they hog the ball, narcissistic players cost their teams a cooperativeadvantage. As the NBA champion Bill Bradley put it, “the success of the group assures the success of the individual, but not the other way around.”

Cynicism can bleed workplaces of creativity, openness, and morale, and the bottom line. The good news is that cynicism is not a life sentence. Researchsuggests that barely a quarter of it is genetic, meaning that the social environment significantly shapes our willingness to give and earn trust. Through the right habits, cynics can build new mindsets and lean into connection.

As a research psychologist and author, I’ve studied the science of cynicism for years. I also work with organizations and leaders to help them fight cynicism and bring the cooperative advantage to their teams. Here are a few places to begin.

We cover Mars mission updates, a new brain implant that shows promise for Parkinson’s, the latest on the mpox outbreak, and more in this week’s new roundup.

Happy Monday, listeners! Let’s kick off the week by catching up on the latest science news. For Scientific American’s Science Quickly, I’m Rachel Feltman.

Last week, NASA’s Perseverance rover started a slow but steady slog. The bot landed in Jezero Crater when it first arrived on Mars back in February 2021. Now it’s busting out—but very slowly and cautiously. NASA says it will take Perseverance months to ascend the rough terrain of the crater’s western rim. The hope is that Perseverance will persevere (sorry) long enough to study a couple sites at the top of the crater.

Speaking of Mars, the Red Planet has really been popping off lately. Earlier this month, a study suggested that Mars might be hiding an ocean’s worth of water deep below its surface. Data from NASA’s late Insight lander revealed seismic signals of liquid water some six to 12 miles beneath the planet’s crust. Then, just a couple of weeks ago, a study showed that rock samples taken by Perseverance contained sulfates. That indicates they probably used to sit in salty water. And back in May, NASA’s tried-and-true Curiosity rover drove over and cracked open a rock that turned out to be packed with pure sulfur. Scientists can’t actually explain how sulfur would have formed in that area, which means there must be something about its past that they don’t know yet.

Now, let’s get into some health news. Last Monday, a study in Nature Medicine described an implant that acts like a pacemaker for the brain. The device builds on the idea of using deep-brain stimulation to treat Parkinson’s, and that generally works by delivering a constant electrical current. Instead, this new treatment uses algorithms to track symptoms, and it delivers brain stimulation only as needed. In a study of four people with Parkinson’s, the researchers said that the tech reduced each person’s most bothersome motor symptom by half when compared with conventional deep-brain stimulation.

Now onto weight-loss drugs. Now, most of the headlines about weight-loss drugs hype a growing number of proposed benefits, but a study out last week argues that doctors should be on the lookout for a troubling side effect. Researchers say that a statistical analysis flagged that people taking semaglutide, which is sold under the brand name Ozempic for diabetes and Wegovy for weight loss, have a higher chance of reporting suicidal thoughts than folks taking other kinds of medication. This was especially true for people who were also taking antidepressants. Now, this is, of course, a preliminary finding that doesn’t prove causation. But some experts say it’s smart to be cautious—especially if you start experiencing new feelings of depression after starting this medication. And honestly, that’s true for any medication and any new signs of depression.

I’m a full-time freelancer, which means I spend my days writing articles from my house. But once upon a time, I commuted to an office every day where I was bombarded with meetings, assignments, Slack channels, and project check-ins.

I like to give each task my full undivided attention, so when something ripped my focus away—like a Slack DM or a coworker walking by—I felt like I got major attention whiplash. I’d lose my flow, and it’d take me a few minutes to get back in it. For a long time, I felt like something was wrong with me because I couldn’t flip between tasks like some of my coworkers, who seemed gifted at doing multiple things at once. But I’ve since learned I’m not a freak (at least not in this way) and that human brains aren’t built for multitasking.

In fact, your brain can only really handle one thing at a time, so when you go through your inbox during a team meeting, you’re not really effectively doing both of these things at the same time. Instead, “your attention is switching—and if your attention is on email then you’re not paying attention to the Zoom meeting,” says Gloria Mark, PhD, Chancellor’s Professor of Informatics at UC Irvine and author of Attention Span and the Substack The Future of Attention. As a result, you’re not accomplishing as much as you think you are (and, most likely, even less than you could be if you were zeroed in on one thing).

When it came time for Itzy Morales Pantoja to start her Ph.D. in cellular and molecular medicine, she chose a laboratory that used stem cells—not only animals—for its research. Morales Pantoja had just spent two years studying multiple sclerosis in mouse models. As an undergraduate, she’d been responsible for ­giving the animals painful injections to induce the disease and then observing as they lost their ability to move. She did her best to treat the mice gently, but she knew they were ­suffering. “As soon as I got close to them, they’d start peeing—a sign of stress,” she says. “They knew what was coming.”

Even though the mouse work was emotionally “very, very difficult,” Morales Pantoja remained committed to her research out of a desire to help her sister, who has multiple sclerosis. Three years after the project wrapped up, however, Morales Pantoja was crushed to find that none of her results would be of any direct help to people like her sister. An antioxidant she’d tested seemed promising in mice, but in human samples it was ineffective.

This was a disappointment but not a surprise. Around 90 percent of novel drugs that work in animal models fail in human clinical trials—an attrition rate that contributes to a $2.3-billion average price tag for every new drug that comes to market.

Today Morales Pantoja is a postdoctoral fellow at the Johns Hopkins Center for Alternatives to Animal Testing, where she is helping to develop lab-grown models of the human brain. The goal is to advance scientific understanding of neurodegeneration while moving the field beyond what some researchers see as an antiquated reliance on animal models.

Millions of rodents, dogs, monkeys, rabbits, birds, cats, fish, and other animals are used every year for research purposes worldwide. Exact numbers are hard to come by, but advocacy group Cruelty Free International estimated that 192 million animals were used in 2015. Most of this work occurs in four broad domains: cosmetics and personal products, chemical toxicity testing, drug development, and drug-discovery research.

Animal-based studies have contributed to important findings and lifesaving medical advancements. The COVID vaccines, for instance, were developed in animals, including mice and nonhuman primates. Animal models have also been critical in advancing AIDS drugs and in developing treatments for leukemia and other cancers, among many other uses.

But animal studies often fall short of producing useful results. They may weed out possibly effective drugs or miss toxicity in humans. They have failed to deliver breakthroughs in certain fields of medicine, including neurological conditions. A 2014 study estimated that candidate therapies for Alzheimer’s disease developed in animal models have failed in clinical trials about 99.6 percent of the time. “As questions about human biology and variability get more complex, we are bumping up against the limits of animal models,” says Paul Locke, an environmental health scientist and attorney at the Johns Hopkins Bloomberg School of Public Health. “The thing you run into with animals—and there’s no way to get around this—is that animal biology is just too different from human biology.” Other species are no longer providing the insights about human biology—including at the cellular and subcellular levels—that scientists today need to achieve innovation.

A growing, multidisciplinary community of researchers around the world is investigating alternatives to animal models. Some are motivated by concerns about animal welfare, but for many, sparing the lives of millions of creatures is just an added bonus. They are driven primarily to create technologies and methods that will approximate human biology and variability better than animals do.

When doctors ask Sara Gehrig to describe her pain, she often says it is indescribable. Stabbing, burning, aching—those words frequently fail to depict sensations that have persisted for so long they are now a part of her, like her bones and skin. “My pain is like an extra limb that comes along with me every day.”

Gehrig, a former yoga instructor and personal trainer who lives in Wisconsin, is 44 years old. At the age of 17, she discovered she had spinal stenosis, a narrowing of the spinal cord that puts pressure on the nerves there. She experienced bursts of excruciating pain in her back and buttocks and running down her legs. That pain has spread over the years, despite attempts to fend it off with physical therapy, anti-inflammatory injections, and multiple surgeries. Over-the-counter medications such as ibuprofen (Advil) provide little relief. And she is allergic to the most potent painkillers—prescription opioids—which can induce violent vomiting.

Today her agony typically hovers at a 7 out of 10 on the standard numerical scale used to rate pain, where 0 is no pain and 10 is the most severe imaginable. Occasionally her pain flares to a 9 or 10. At one point, before her doctor convinced her to take antidepressants, Gehrig struggled with thoughts of suicide. “For many with chronic pain, it’s always in their back pocket,” she says. “It’s not that we want to die. We want the pain to go away.”

Gehrig says she would be willing to try another type of painkiller, but only if she knew it was safe. She keeps up with the latest research, so she was interested to hear earlier this year that Vertex Pharmaceuticals was testing a new drug that works differently than opioids and other pain medications.

That drug, a pill called VX-548, blocks pain signals before they can reach the brain. It gums up sodium channels in peripheral nerve cells, and obstructed channels make it hard for those cells to transmit pain sensations. Because the drug acts only on the peripheral nerves, it does not carry the potential for addiction associated with opioids—oxycodone (OxyContin) and similar drugs exert their effects on the brain and spinal cord and thus can trigger the brain’s reward centers and an addiction cycle.

In January Vertex announced promising results of clinical trials of VX-548, which it is calling suzetrigine, showing that it dampened acute pain levels by about one half on that 0-to-10 scale. The company is applying for U.S. Food and Drug Administration approval for the drug this year.

Other pain drugs that target sodium channels are now being developed, some by firms motivated by Vertex’s success. Navega Therapeutics, led by biomedical engineer Ana Moreno, is even using molecular-editing tools such as CRISPR to suppress genes involved in chronic pain. “We are definitely hopeful that we can replace opioids, and that’s the goal here,” she says.

One in five U.S. adults—51.6 million people as of 2021—is living with chronic pain. New cases arise more often than other common conditions, such as diabetes, depression, and high blood pressure. Yet pain treatments have not kept pace with the need. There are over-the-counter pills such as aspirin, acet­aminophen (Tylenol), and nonsteroidal anti-inflammatories (NSAIDs) such as Advil. And there are opioids. The glaring inadequacy of existing medications to alleviate human suffering has fueled the ongoing opioid epidemic, which has led to more than 730,000 overdose deaths since its start.

Your fellow teachers have apparently not gotten the memo yet that it’s 2024 and constantly asking questions about whether someone else is or wants to be pregnant is totally intrusive! But let’s deal with your reality: You may have opened the door for their comments by mentioning you are trying to get pregnant. Still, that doesn’t give them the right to follow up constantly. So many people struggle with infertility—even Democratic vice presidential nominee Tim Walz and his wife have talked openly about their difficulties!—it’s really time to get with the program. You don’t want to be rude, but I think you just have to say, maybe when you are in the teachers’ lounge with a group or at lunch: “I know I mentioned that we were trying for a baby, but we’re taking a break, so it would be great if you didn’t bring it up, as it’s sensitive right now.” That’s not rude. It’s taking care of yourself and your mental health.

That said, I am also concerned about how you’re casting blame for your infertility. Why was it important for Prudie to know that the issue is on your husband’s side? You say it’s “not your body that’s the problem.” Ouch. Imagine if the primary struggle with getting pregnant was on you, and that’s how your husband described it. It takes two (or at least a sperm and an egg) to get pregnant; your infertility is a shared struggle. I suggest you start thinking that way instead of blaming your partner for something outside of his control.

Most of the matter in our universe is invisible. We can measure the gravitational pull of this “dark matter” on the orbits of stars and galaxies. We can see the way it bends light around itself and can detect its effect on the light left over from the primordial plasma of the hot big bang. We have measured these signals with exquisite precision. We have every reason to believe dark matter is everywhere. Yet we still don’t know what it is.

We have been trying to detect dark matter in experiments for decades now, to no avail. Maybe our first detection is just around the corner. But the long wait has prompted some dark matter hunters to wonder whether we’re looking in the wrong place or in the wrong way. Many experimental efforts have focused on a relatively small number of possible identities for dark matter—those that seem likely to simultaneously solve other problems in physics. Still, there’s no guarantee that these other puzzles and the dark matter quandary are related. Increasingly, physicists ac­­knowl­edge that we may have to search for a wider range of possible explanations. The scope of the problem is both intimidating and exhilarating.

At the same time, we are starting to grapple with the sobering idea that we may never nail down the nature of dark matter at all. In the early days of dark matter hunting, this notion seemed absurd. We had lots of good theories and plenty of experimental options for testing them. But the easy roads have mostly been traveled, and dark matter has proved more mysterious than we ever imagined. It’s entirely possible that dark matter behaves in a way that current experiments aren’t well-suited to detect—or even that it ignores regular matter completely. If it doesn’t interact with standard atoms through any mechanism be­­sides gravity, it will be almost impossible to detect it in a laboratory. In that case, we can still hope to learn about dark matter by mapping its presence throughout the universe. But there is a chance that dark matter will prove so elusive we may never understand its true nature.

On a warm summer evening in August 2022, we huddled with a few other physicists around a table at the University of Washington. We were there to discuss the culmination of the “Snowmass Process,” a year-­long study that the U.S. particle physics community undertakes every decade or so to agree on priorities for future research. We were tasked with summing up the progress and potential of dark ­matter searches. The job of communicating just how many possibilities there are for explaining dark matter, and the many ideas that exist to explore them, felt daunting.

We are at a special moment in the quest for dark matter. Since the 1990s thousands of investigators have searched exhaustively for particles that might constitute dark matter. By now they’ve eliminated many of the simplest, easiest possibilities. Nevertheless, most physicists are convinced dark matter is out there and represents some distinct form of matter.

A universe without dark matter would require striking modifications to the laws of gravity as we ­currently understand them, which are based on Einstein’s general theory of relativity. Updating the ­theory in a way that avoids the need for dark matter—either by adjusting the equations of general relativity while keeping the same underlying framework or by introducing some new paradigm that replaces general relativity altogether—seems exceptionally difficult.

The changes would have to mimic the effects of dark matter in astrophysical systems ranging from giant clusters of galaxies to the Milky Way’s smallest satellite galaxies. In other words, they would need to apply across an enormous range of scales in distance and time, without contradicting the host of other precise measurements we’ve gathered about how gravity works. The modifications would also need to explain why, if dark matter is just a modification to gravity—which is universally associated with all matter—not all galaxies and clusters appear to contain dark matter. Moreover, the most sophisticated attempts to formulate self-consistent theories of modified gravity to explain away dark matter end up invoking a type of dark matter anyway, to match the ripples we observe in the cosmic microwave background, leftover light from the big bang.

Aren’t we stuck with the traits we’re born with?

Actually no, says science. Of course, genetics plays some role in personality. As anyone who has dealt with two or more toddlers can tell you, some of us are born shyer or chattier than others, and these tendencies follow us to some extent throughout our lives.

But when one 64-year-long study examined personality tests for the same individuals over decades, it found basically no relationship between people’s results in their teens and their later years. You are a totally different person at 72 than you were at 14. 

Which invites the question, if personality shifts over time, can you consciously control the process? Can you speed it up? Can you direct it? The answer according to both fascinating personal experience and research appears to be yes.

From teenage slacker to successful achiever 

We’ll start with a personal story from Shannon Sauer-Zavala, a University of Kentucky psychology professor. In a recent Psychology Today post, she explained she definitely wasn’t voted most likely to succeed in high school. In fact she was a shy, messy wallflower who skipped so many math classes she needed to repeat algebra and was repeatedly told by teachers she “wasn’t living up to her potential.”

Now she has a PhD, a TEDx Talk, and a successful career under her belt, and she regularly puts herself out there as living proof that personality change is possible. 

“I love telling people about my own personality change story as a way to bust the myth that traits are set in stone,” she writes. So how did she do it?

Sauer-Zavala seems to have been lucky enough not to be carrying any extreme trauma or a difficult diagnosis. She was just a run-of-the mill, low-motivation high school kid, which allowed her to mold her personality with little more than curiosity, passion, and a series of small, doable behavior shifts. 

First, she stumbled on psychology in college and discovered something she truly was interested in.

As a child of Holocaust survivors, growing up in a multilingual immigrant house­hold, author Elizabeth Rosner became a careful listener of both the spoken and the unspoken. Her expansive, fluid meditation on so-called third-ear listening—a deeply attuned, intuitive way of perceiving the world that transcends the physically audible—is rooted in personal experience, but the contemplative vignettes explore our sonic universe. Drawing together topics ranging from the rise of podcasting to the vibration-detection sensitivity of an elephant’s foot, this poignant exploration of the hidden depths of the soundscapes around us reveals the importance of listening with more than just our ears.

Book Description

This illuminating book weaves personal stories of a multilingual upbringing with the latest scientific breakthroughs in interspecies communication to show how the skill of deep listening enhances our curiosity and empathy toward the world around us

Third Ear braids together personal narrative with scholarly inquiry to examine the power of listening to build interpersonal empathy and social transformation. A daughter of Holocaust survivors, Rosner shares stories from growing up in a home where six languages were spoken to interrogate how psychotherapy, neurolinguistics, and creativity can illuminate the complex ways we are impacted by the sounds and silences of others.

Drawing on expertise from journalists, podcasters, performers, translators, acoustic biologists, spiritual leaders, composers, and educators, this hybrid text moves fluidly along a spectrum from molecular to global to reveal how third-ear listening can be a collective means for increased understanding and connection to the natural world.

About the Author

ELIZABETH ROSNER is a bestselling novelist, poet, and essayist. Her works include Survivor Café: The Legacy of Trauma and the Labyrinth of Memory, a finalist for the National Jewish Book Award, and the novel Electric City, named a best book by NPR. Rosner’s essays have appeared in The New York Times Magazine, Elle, and numerous anthologies. She lives in Berkeley, California.
