Psychologist found the first corporate psychopath—a 17th century Dutch mutineer

23 October 2026 at 17:48

The concept of a corporate psychopath is eerily recognizable, depending on your work history. It’s also notoriously misunderstood. The archetype of the manipulative, self-serving manager has regularly resurfaced in popular culture for decades, but concrete evidence supporting the wider concept is debatable. For example, a research study went viral in 2016 after estimating upwards of 1-in-5 business employees fit the “psychopath” bill, only to be retracted two years later. Additionally, psychiatrists widely agree that only about 1 percent of the general population truly can be considered clinically psychopathic.

That said, many of the people determined to claw their way to the top of the company ladder display at least some of the trademark psychopathic behaviors. Many theorists have convincingly argued this has a lot to do with corporate capitalism’s foundational principles, which leave it easily exploited by the most ruthless and manipulative among us.

Clive Boddy, one of the world’s foremost investigators of corporate psychopathy, recently took this idea to its logical historical conclusion. In a study recently published in the Asian Journal of Business Ethics, Boddy reviewed one of toxic corporate leadership’s earliest documented examples—and he makes today’s nightmare coworkers sound tame in comparison.

Who was Jeronimus Cornelisz?

Meet Jeronimus Cornelisz, an all-time contender for World’s Worst Boss. According to archival accounts, the 17th century Dutchman Cornelisz embodied every core corporate psychopath characteristic over 400 years ago while working for the conglomerate that started it all: the Dutch East India Company.

Established in Amsterdam in 1602, the Dutch East India Company is arguably the world’s first multinational, shareholder-owned company. It quickly amassed enough funds and power to rival most sovereign countries through the import and export of spices, tea, luxury items, coffee, wine, and enslaved populations. The Dutch East India Company eventually exerted enough influence to wage its own wars, mint its own currency, form colonies, as well as arrest and execute convicts.

All of this was made possible through a vast fleet of ships,but even the best outfitted vessels sometimes fell afoul of nature. In June 1629, a Dutch East India Company’s flagship called Batavia collided with a reef off the Western Australian coast. Nearly 300 survivors made it to the nearby island shores, but their remote location ensured they wouldn’t survive without help. The ship’s senior officers soon set off in an open longboat on a 1,900-mile journey to present-day Jakarta, then the Dutch East Indies’ capital. Before leaving, they appointed under-merchant Jeronimus Cornelisz to the top corporate position in their absence.

Mutiny, murder, and malignant narcissism

Unbeknownst to Batavia’s departing senior crew, Cornelisz had already spent weeks scheming on ways to incite a mutiny. The plan was to take control of the vessel then steer its copious stores of gold and silver to a new life. Cornelisz apparently viewed getting marooned as an inconvenient detour, and quickly got to work on his hostile takeover.

According to firsthand accounts, Cornelisz immediately consolidated power by swapping fellow council members with loyalists and requiring them to pledge an oath of allegiance to him. Next, he tricked suspected opponents under the direction of a soldier named Wiebbe Hayes to search a nearby island for supplies, then left them to die.

Although his revised plan required any impending rescue ship, Cornelisz’s ultimate goal remained the same—get as far away as possible, then start his own kingdom using riches plundered from Batavia. Over the ensuing months, Cornelisz directed his gang to kill more than 100 of the shipwrecked men, women, and children. Cornelisz often justified the murders under the pretense of conserving food and water, when in actuality he was continuing to eliminate perceived threats. Meanwhile, some of the surviving women were subjected to sexual abuse.

However, Cornelisz underestimated his abandoned compatriots. As the operatically psychopathic Cornelisz terrorized his group of survivors and scrounged for supplies, Hayes’ team reportedly discovered freshwater wells and hunted local wallabies, seals, and fish. The two sides subsequently squared off on multiple occasions after learning of each others’ continued existence until a rescue ship finally arrived in October 1629. After nearly three months, only about a third of Batavia’s original passengers and crew were left.

Cornelisz receives his company review

Management ultimately decided Cornelisz wasn’t internal promotion material, even by Dutch East India Company standards. Nearly everyone involved in his reign of terror was executed. As for Cornelisz and his closest loyalists, authorities eventually hanged them, but not before cutting off their hands.

The tragedy of the Batavia is an admittedly extreme case study, but Boddy argued that it illustrates how corporate structures have facilitated and encouraged psychopathic behaviors since the invention of the corporation itself.

“The same playbook we see in toxic workplaces today appears in this case from 1629,” he said. “He removed opponents, rewarded loyalists, created fear, manipulated followers and pursued power at any cost.”

A corporate (psychopath) case study

In recent years, some historians have expressed doubts about details in the Batavia saga after reviewing available evidence and recontextualizing cultural dynamics. Instead of focusing on the machinations of a single ruthless corporate psychopath, they contend Batavia is more accurately a case study in group desperation. But even when viewed under this lens, the chilling event is still a cautionary tale about corporate capitalism’s darker underpinnings.

“Perhaps the most striking finding is that another leader facing the same circumstances achieved completely different outcomes,” Boddy said. “This was effectively a natural experiment in leadership. One group prospered while the other descended into murder and abuse.”

Women are more emotionally intelligent than men, and that’s a problem

Who comes to mind when you think of someone emotionally intelligent? Someone who can read a room, defuse an argument, and who knows exactly what to say when a friend is struggling? For many people, that person is a woman. It’s such a widely held belief that popular psychology treats it as fact.

We decided to put that assumption to the test. Our new study reviewed nearly three decades of research, from 1995 to 2023, across 76 countries and more than 600,000 people. We wanted to answer a simple question: are women really more emotionally intelligent than men? The headline answer is yes, on average, women score higher.

But the more useful finding is the type of emotional intelligence women seem to excel at, and what it potentially costs the people who have it.

Emotional intelligence is the ability to recognise, understand and regulate emotions in yourself and in others. When we looked at each element of emotional intelligence, the female advantage turned out to be concentrated in the “others’ feelings” half of the equation.

This means recognising what someone else is feeling, understanding why and helping them manage it. A child has a meltdown, a colleague goes quiet after their idea gets dismissed in a meeting, a negotiation gets tense. Plenty of men are excellent at this too, and plenty of women aren’t; these are averages across hundreds of thousands of people, not predictions about any one person in the room.

Is that gap simply biology? We can’t rule biological or hormonal factors out entirely. But two patterns in our data point elsewhere. The female advantage is far smaller in children than in adults, and this gap has been narrowing across the three decades our data spans. That’s not what you’d expect from something fixed at birth. Although the data in our study cannot tell us the exact reasons these differences emerge, this pattern aligns with what you’d expect from something shaped through practice.

There’s a plausible source for that practice, too. Other research has found that parents use a wider vocabulary of emotion words with daughters than sons, and more often encourage girls to reflect on and articulate their feelings.

Boys, meanwhile, are more often steered toward managing emotions by suppressing them. Their sisters are encouraged to work through it with other people – exactly the kind of social and emotional skill our data shows women excel at.

Put simply, girls appear to get more practice reading and responding to other people’s emotions, starting early in life. Like any skill built through repetition, whether it’s learning a new language or picking up a new instrument, the more you practice, the more natural it becomes.

In fact a 2019 meta-analysis of 58 studies found that emotional intelligence can be trained. Gender didn’t seem to impact the effectiveness of learning how to be more emotionally intelligent.

That’s good news. If emotional intelligence is a trainable skill rather than a fixed trait, the gap isn’t destiny. That means men can benefit from these skills too, including in negotiations and at work.

But there’s a less comfortable implication, too. If women’s advantage here goes unrecognised as a skill and gets treated instead as “how women are”, it becomes very easy to take for granted. The colleague who’s good at defusing tension becomes the one who’s always expected to do so. A capability quietly turns into an obligation: unpaid and unrewarded.

This plays out in the workplace every day. Organisations benefit when employees manage team tension, support stressed colleagues and smooth over conflict. It is work that keeps a team functioning but almost never shows up in a performance review.

Two practical shifts need to follow our study findings. First, employers should name this work and reward it, in reviews and in promotion decisions. Second, invest in developing these abilities in all staff.

The same logic holds outside the office. In families and friendships, the person who remembers a friend is having a bad week and checks in without being asked, who notices when someone stops responding in the group chat, who always asks a family member about their day is doing real work too, and that work is often taken for granted precisely because it looks effortless.

None of this means women don’t have a real strength here. Our data shows a female advantage in emotion abilities. But a strength that’s assumed rather than trained, and expected rather than shared, isn’t something to reinforce. It’s untapped potential for men. The person everyone turns to when things get hard isn’t lucky or simply built that way: they’ve probably had more practice.

What we haven’t done is give everyone else that same opportunity or incentive to practice, or made clear emotional intelligence was a skill worth building in the first place.The Conversation

Study of 1,678 Children’s Past-Life Claims Finds a Pattern That Skeptical Families Show Most Strongly

What do you make of a young child who says they remember being someone else? A team at the University of Virginia has not tried to answer that.

Monkeys also avoid germs after viral outbreaks 

21 October 2026 at 00:05

When a new disease emerges, things can get a little weird. We start to clean groceries with antibacterial wipes, the sound of a sneeze can trigger our fight-or-flight response, and we generally become more cautious. Humans may not be the only primate species that change their behavior in the face of disease. 

According to a study published today in the journal Royal Society Open Science, Japanese macaques (Macaca fuscata) that lived through a deadly outbreak in 2020 became noticeably more cautious about food that appeared contaminated, even though this disease was not spread by food or feces. This indicates that purposefully shifting behavior to avoid a pathogen can be shaped by our appearance and that disgust may have deep evolutionary roots. It also sheds light on the behavioral immune system—a collection of behaviors that help animals avoid an infection before the biological immune systems respond.

“We can show now, in non-human primates, that this is the same for them,” Federico Rossano, a study co-author and cognitive psychologist at the University of California San Diego, said in a statement. “Even with no knowledge of how disease is transmitted, being exposed to others getting sick and dying changes the likelihood of engaging in behaviors that potentially could lead to some form of sickness.”

2020 was a big year for outbreaks

In 2020, the staff at a primate sanctuary in southern Texas confirmed the presence of simian retrovirus Type II. This disease can cause AIDS-like immunodeficiency and is primarily transmitted through bites and scratches. It caused severe illness and death in some of the monkeys. The sanctuary staff separated the groups and implemented testing and quarantine measures in response to the outbreak. Since the groups live in separate enclosures, scientists then had the chance to compare animals with similar backgrounds that had experienced very different social and disease environments. 

In total, three groups of monkeys experienced the outbreak while one had not. The team tested 

55 macaques to see how they responded to a choice between food that was put on a clean wooden surface and food placed on a surface covered with real macaque feces. The food with the feces was sealed under a layer of clear epoxy, so that the monkeys could see the food and poop without risking infection.

In the group that had been exposed to the outbreak, some of the individuals had been infected while others had lived alongside sick monkeys without getting sick. This allowed the researchers to question if experiencing an outbreak without getting infected could change the macaque’s behavior. To test that further, the clean surface was replaced with a brightly colored kitchen sponge in some of the scenarios to see if the animals were just avoiding unfamiliar objects. 

Previous studies found that macaques aren’t necessarily deterred by contamination—as long as the payoff is tempting. When presented with a favorite treat (such as a peanut) wild Japanese macaques would still eat food from a surface covered in feces, but will avoid it for food like grains of wheat.

Continued caution

The team found that macaques from groups that went through the outbreak were far less likely to eat the food from the contaminated surface. They ate from the fake contaminated surface in only 47 percent of trials. The monkeys that did not experience the outbreak ate from the potentially contaminated surface in 79 percent of trials.

The monkeys from outbreak-exposed groups also behaved similarly whether or not they themselves had been infected. According to the team, this suggests the behavioral change was associated with their experiencing living through the outbreak, instead of actually getting sick

“Groups have histories, and those histories show up in behavior,” added study co-author and UC San Diego cognitive psychologist Stephan Kaufhold. “Living through the disease outbreak appears to have made those monkey groups more cautious around food that looks contaminated.”

The virus was spread through blood or saliva from bites and scratches, and not through contaminated food. Interestingly, the macaques who saw their fellow primates get sick, were more reluctant to eat food placed on a surface that visually suggested contamination in some of the tests.

Disgust’s evolution

In addition to shedding light on how illness affects primate behavior, it also offers insight into the evolution of disgust. The team did not measure disgust directly, but found that monkey’s avoidance of potential sources of infection can change with their experience, similar to what humans do.

Human disgust is believed to play an important role in protecting us from pathogens. We recoil from the smell and sight of poop, spoiled food, and other potential sources of infection. Our sensitivity to those cues can also change depending on context.

Since primates are capable of social learning, the team believes that heightened pathogen avoidance could be learned from other members in the group and persist over time. Future studies could see if newly introduced animals adopt the behavior of a group that has already experienced an outbreak.

For the first time, artificial intelligence is a top 10 fear in the U.S.

20 October 2026 at 17:05

It’s official—artificial intelligence is one of the top 10 fears in the United States. Well, it’s technically two of the top 10 fears, according to the 12th annual Chapman University Survey of American Fears.

First conducted in 2014, the recurring questionnaire tracks yearly anxiety trends that often range from everyday concerns to existential terrors. This year, 61.1 percent of over 1,200 respondents once again cited “corrupt government officials” as their biggest fear—the same subject was last year’s number one entrant as well as its 11th year on the list. After that, it’s the fear of another world war (51.9 percent). However, “AI harming the political process” wasn’t too far behind for third place at 51.9 percent. The technocentric worry is now essentially tied with the fear of loved ones becoming gravely ill (51.8 percent).

That said, the survey’s own plus or minus 3.79 percentage point margin of error complicates the results a bit. Taking the margin of error into consideration, it’s a tossup when trying to definitively rank the list’s third through tenth fears. Regardless, about 49.7 percent survey takers are also anxious about AI negatively impacting the economy—a double dose of AI-centric woes for the first time in the survey’s history. It’s also the first year researchers at Chapman University in California included questions about AI, but they made it clear it likely won’t be the last.

“As artificial intelligence becomes more integrated into everyday life, understanding these fears will be increasingly important,” said Chapman University sociologist and survey creator Christopher Bader. “We expect concerns about AI to remain a significant part of the national conversation in the years ahead.”

It’s understandable why AI currently vexes so many people. The blanket term now encompasses everything from photorealistic fake images, to dubious search engine chatbots, to nebulous doomsday warnings. Despite these worries, the AI industry’s biggest threats arguably remain the rampant spread of misinformation, coupled with a lack of meaningful regulations or oversight.

But no matter your top technological fear, survey organizers still believe the annual report highlights a very relatable human emotion.

“What I’m seeing more and more over time is that our fear about our loved ones is going to always be there, no matter what’s going on in the world,” said sociologist Ashley Kranjac, director of Chapman University’s Earl Babbie Research Center.

The remarkable bond between a man and a deer

18 October 2026 at 20:00

Excerpted from PENELOPE by Paul Bochner. Copyright © 2026 by Paul Bochner. Published in the United States by Crown, an imprint of the Crown Publishing Group, a division of Penguin Random House LLC. 


On the evening of March 18, as it was growing dark, I went to the window, not knowing what was drawing me. Next to the house stood a shadow, ghost-like, shrunken, at one with the dusk, almost translucent, and I recognized The Girl with the Broken Foot.

I walked out into the falling wet snow, slowly approaching her, and she allowed me to come close. Nine months old, she was the size of a fawn half that age. Starkly emaciated, her body seemed to be collapsing inward, her head held low. Literal hunger and a deeper starvation were palpable. She bore the haunted look of terminal solitude seen in souls driven to the margins of society, among the liv-ing, yet apart. She seemed so frail that I couldn’t imagine she would live more than another day or two.

Going inside and returning with a bowl of apples, I cut them into pieces and placed a few on the ground between us. She was raven-ously hungry and I gave her a few more apples, and still more, until she had eaten a total of eight. After she had finished eating, she stayed with me. We stood about a foot apart. She showed no fear of me, a fact which I would later come to recognize as meaningful. The moment had the compelling quality which has been present at the onset of many enduring connections in my life, of being un-bound by linear time.

“I am watching over you,” I said softly. “If you come here, I will take care of you. You are not alone.”

It was fully dark when we parted, having been together for an hour. I expected that she would recede into the woods, yet the next morning she was sleeping against the house, directly beneath the window closest to where I sit all day to work. Save for the wall separating us, she could not have gotten any closer to me.

When I went around to the front of the house, she struggled to her feet and approached. In the morning light, I was better able to assess the state of her health. Months of solitary survival had taken a severe toll. Her body seemed hollowed, her ribs and pelvis sharply visible beneath her skin, and it felt a miracle that she was alive. On her right flank was a hemispherical mass the size of a cantaloupe, which I took to be a tumor, yet it had an open, running wound at its center, which she periodically craned her neck to lick. Her eyes were running and had congealed masses at their inner corners.

I bent to get a look at her injured foot. From not being walked on, the backward-facing cloven hoof had grown to an abnormal length and was curling upward. The wrist, which unnaturally bore her weight, had a flattened forward surface, an oval about two inches across, worn raw, without hair or skin, only pale pink–grey flesh, which, at its center, appeared to have been further abraded to the bone. Her right front foot, forced to compensate, was splayed and rockered, her right scapula protruded, and her front quarters were substantially lower than her hips.

I again placed apple pieces on the ground between us. I spoke very gently to her, saying, “You are the best one of all the deer. You are the most beautiful. You are good.” I continued to talk to her while she ate her apples, and when she had taken all she could, she returned to her resting spot under the window. I went inside to work, keeping periodic watch, pleased that she seemed to have claimed a place. But in a few minutes, from around the corner of the house came the twins, followed by their mother who immediately and ag-gressively charged at her. The Girl with the Broken Foot lurched upright and hobbled down the embankment, across the road and into the woods.

She was once again alone, but a step had been taken. Since the previous evening, things had changed. Even before her second feed-ing she had recognized me on sight. She had approached and had again allowed me near.

Although I had seen her fewer than half a dozen times in the preceding months, from the night of our first connection, she began to come to the house every day. She slowly gained strength and I would watch for her and thrill to the sight of her slow approach. It was our private time. We stood together, and I placed her food on the ground between us. After she ate, she would stare into my eyes for long periods, seemingly entranced. I told her stories. I sang softly to her. I told her she was my beauty.

So began our journey, and one of the greatest loves I have ever known.

Your eyes dilate depending on your thoughts

16 October 2026 at 16:45

Your eyes really can betray your thoughts, but don’t get too self-conscious about it. Researchers in Japan believe that the subtle signs our eyeballs make are more useful to neuroscientists than the interrogation room. Based on their findings recently published in the journal iScience, examining the difference physiological responses from “inner” versus “overt” speech may help us better understand everything from linguistic development in children to the efficacy of silent pep talks.

To learn more, a team at the University of Tsukuba in Honshu enlisted dozens of volunteers for a series of simple counting exercises. After observing the participants at rest while thinking about nothing in particular for a control, researchers then asked them to count sequentially (1, 2, 3…), in number-subject combinations (one dog, two dogs…), and in specific intervals (1, 3, 5…). They also completed each task both silently and aloud. In each phase, the team carefully monitored their pupil dilation.

The results were subtle, but striking. Participants’ pupils dilated during each overt speech task, but this same muscle movement depended across each inner speech directive. Pupils constricted while volunteers silently counted sequentially, dilated for interval counting, and didn’t change at all for number-subject counting. But regardless of the inner speech task, pupil size changes were always smaller than they were during overt speech.

“The results of the present study do not support the initial assumption that inner and overt speech produce equivalent pupillary responses,” the team summarized. “Across the three experiments, overt speech consistently elicited pupil dilation, whereas inner speech did not.”

This collective data indicates that our inner speech isn’t simply the nonverbal counterpart to talking aloud. Instead, it’s a form of communication that appears to correspond to lower levels of brain arousal. If true, measuring pupil dilation may become a valuable tool when attempting to assess internal language and thinking. This could be particularly useful for studying language development in young children and infants who can’t properly describe their experiences to adults yet.

In 1976, a college paper blamed the Salem witch trials on moldy bread. It wasn’t true.

15 October 2026 at 14:02

In the mid-1970s, Linnda Caporael was a college student facing a seemingly mundane decision. 

A science major at U.C. Santa Barbara, she needed a humanities course to graduate. The course she chose, on women in American history, came with a term paper, and she had to pick a topic.

Caporael’s first choice—Lydia Wardell, a Quaker woman who protested Puritan persecution by walking naked into a meeting house in the 1660s—was intriguing, but already taken. So Caporael instead settled on her second choice: Ann Putnam, one of the accusers in the 1692 Salem witch trials. In doing so, Caporael reshaped the way millions of people view a nearly 300-year-old chapter of American history. 

Caporael’s paper introduced the theory that the visions, convulsions, and distress the “afflicted” girls reported might not have been supernatural after all. Instead, she proposed, they could be explained by ergot, a fungus that grows on rye grain and produces a hallucinogenic toxin. In other words, blame moldy bread. 

The ergot theory, despite being debunked within a year of being published, has continued to spread and thrive like fungus on rye. As recently as 2023, comedian-turned-podcasting-juggernaut Joe Rogan discussed the theory enthusiastically on his show, effectively reanimating a story that seems destined to never fully die.

“It’s sexy,” says historian Margo Burns about the enduring appeal of Caporael’s ergot theory. “It’s about drugs. It’s about witches. It’s about killing people. Also, we like to think that when there’s an unjust sentence or execution, there’s someone or something to blame.”

Burns, a Salem scholar who has spent years tracing how the ergot theory took hold and persisted, says she rarely gets through a talk on the trials without someone in the audience bringing up moldy bread.

How a term paper went viral

The fact that a single undergraduate college paper could have such a lasting and wide-ranging impact on our understanding of the Salem witch trials seems bizarre, but it can be explained in part by a thoroughly modern phenomenon: virality. Although the World Wide Web was still decades away, Caporael’s paper found a way to spread fast through newspaper wire services.

After she started graduate school, Caporael submitted the paper to Science, which, to her surprise, published it in April 1976. That alone might have kept the theory confined within academic circles. Instead, newspaper editors saw a story with mass appeal.

“Editors and newspapers just grabbed it, saying, ‘Oh, here’s a human interest thing,’” Burns says. “And when they put it in their papers, like The Washington Post, The New York Times, The Boston Globe, it got syndicated. And the syndication of those articles went through the whole country and Canada within a matter of weeks.”

Caporael, who had explored the topic through the lens of the scientific method, wasn’t claiming to know what had happened at Salem. At the suggestion of a pre-med friend, she began looking into ergot poisoning as a possible explanation, not a definitive answer. 

According to Burns, who has spoken with Caporael directly, she was only testing whether ergot could be ruled out. Working from the limited sources available to her, Caporael determined that she couldn’t rule it out. Even then, though, she called her own findings “suggestive,” not conclusive.

But that nuance didn’t survive exposure to the public, which in 1976 was already fixated on LSD and what it might do to young people. The press coverage essentially retrofitted 1692 with the anxieties of 1976, recasting the Salem girls as teenagers on a bad trip.

“You give that to the American public, which doesn’t understand there’s a difference between scientific inquiry and historical storytelling, and it’s just so compelling,” Burns says.

Debunked, but far from dead

Not all the viral attention was positive, though. Within that same year, researcher Nicholas Spanos and graduate student Jack Gottlieb published a rebuttal in Science, dismantling Caporael’s argument point by point. By their reckoning, various aspects of the Salem girls’ symptoms did not add up. 

“There are a couple of different kinds of ergot poisoning, and one of them is gangrenous, so people’s fingers would start rotting,” Burns says. “And they would have gastrointestinal problems, and we don’t have any instances in the records that either of those things happened.”

The problems for the theory didn’t end there. Ergot poisoning was thought to hit hardest among people with vitamin A deficiencies, but Salem’s residents had dairy cows and the sea nearby, and likely plenty of vitamin A. (Ironically, Burns notes, that the vitamin A argument was itself based on a discredited 1930s source that relied on circumstantial evidence and has never been replicated.) And while whole families ate from the same supply of rye, usually only one or two people per household fell ill.

The rebuttal, though methodical and logical, was little more than a momentary speed bump for the runaway popularity of the psychedelic bread story. In fact, it may have helped. 

Arguing with a claim, however insubstantial, implies that it’s worth arguing about, and a formal rebuttal in Science can make a student’s term paper look like one side of a valid scientific debate.

“It’s really hard to refute something,” Burns says. “If anything, it just sort of nails it and makes it more permanent.”

“They were eating their own”

Whatever was causing young women in Salem to convulse, the atrocities that followed are much harder to grasp. By the time the panic ended, 152 people had been formally accused, 19 had been hanged, and one man, Giles Corey, had been pressed to death with stones for refusing to stand trial. Several more died in jail.

“The people who were responsible were the adults in the room,” Burns says.

Related 'That Time When' Stories

To the modern eye, this looks like lunacy. To most people in 1692, though, witchcraft wasn’t superstition. It was an accepted fact, part of an invisible world in which Satan and his agents wreaked havoc on everyday life. Conflict with Indigenous peoples on the Maine frontier had sent traumatized refugees into the region, relating horror stories of attacks on their homes. Many colonists thought Satan engineered those attacks, too.

In a way, the people of Salem did exactly what Americans would do nearly 300 years later, when the psychedelic era latched onto the ergot theory: They explained strange behavior through the lens of what frightened them most.

In such a charged social climate, suspicion could fall on just about anyone, and it did. The accused weren’t just outcasts, Burns says. Many were fully covenanted members of the Puritan church.

“We’re not talking about going after ‘The Other,’” she says. “They were eating their own.”

Someone to blame

Burns knows the cost of Salem’s betrayals about as well as anyone. An associate editor of Records of the Salem Witch-Hunt, the definitive collection of the trials’ legal records, she is also the 10th-generation great-granddaughter of Rebecca Nurse, who was hanged on the charge of witchcraft in 1692.

Nurse, a respected member of the church in Salem Town, was tried and found not guilty. But Chief Justice William Stoughton refused to accept the verdict. He sent the jury back to reconsider a remark Nurse had made when confessed witches Deliverance Hobbs and her daughter, Abigail, were brought in to testify against her: She had said the two were “of our company.” Nurse meant that they had been jailed together, but the court heard that they were fellow witches. 

When jurors asked her what she meant, the courtroom was in such an uproar that Nurse didn’t hear the question. At the time, failing to answer an accusation was treated as a confession, and the jury returned a guilty verdict. In a later appeal, Nurse wrote that she was “something hard of hearing, and full of grief,” and didn’t realize she was being asked to explain herself.

It was the kind of injustice no mere fungus could cause.

“[Chief Justice] Stoughton was singularly, individually responsible for her execution,” Burns says.

The question of who is to blame is rarely so straightforward, though. Which might be part of the ergot theory’s appeal; it offers “one silver bullet” that tidily explains everything.

“There are just so many reasons that all came together,” Burns says.

But when pressed on why she thinks it happened, she offers an answer that’s part joke, part harsh reality: “People are mean.”

Scientists Develop “Pizza Model” to Reveal Hidden Links in Complex Networks

16 September 2026 at 12:13

Networks shape much of the world around us. Friendships form social networks, computers connect through the internet, brain regions communicate with one another, and countries are linked through trade. However, scientists often face two major difficulties when studying these systems. They may see only part of a network, and they must decide whether an apparent […]

How chimps teach their kids tool tricks

16 September 2026 at 05:00

Chimpanzees are known to use rudimentary tools when foraging for food. According to a new paper in the journal Frontiers in Psychology, this learned behavior is passed down from adults to offspring through social learning. Specifically, adult chimps deliberately model the behavior, then turn their tools over to the youngsters so they can mimic the same motions.

"Receiving food and tools from experienced individuals, which we call food or tool transfer, may help chimpanzees learn to use technology to extract foods that are difficult to access,” said co-author Andreu Sánchez-Megías, a graduate student at the University of Barcelona and the Jane Goodall Institute Spain in Senegal. “Tool transfers thus appear to be a form of teaching, together with observation and supervised practice. It appears that mothers are the main models and teachers for young chimpanzees in this manner.”

As we have previously reported, tool use was once thought to be one of the defining features of humans, although Charles Darwin observed chimpanzees using stones to crack nuts in 1871. In 1960, the late primatologist Jane Goodall observed a chimp named David Greybeard bend a twig, strip off the leaves, and use it to spoon termites out of a nest and into his mouth. When he learned of the behavior, Goodall's mentor, Louis Leakey, famously observed, “Now we must redefine ‘tool,’ redefine ‘man,’ or accept chimpanzees as humans.” Since then, chimps have been observed making sponges out of leaves to soak up liquids, shaping sticks to collect algae, and sharpening rudimentary spears for hunting.

Mathematician Says Relationships Have a Critical Threshold—and Crossing It Can Predict When Love Falls Apart

14 September 2026 at 14:05

Equations once used to predict whether populations of rabbits would boom, stabilize, or collapse are now being applied to something potentially even more complicated: romantic relationships.

According to mathematician Laurent Pujo-Menjouet of Claude Bernard University Lyon 1, the forces that determine whether a couple survives life’s inevitable stresses can be studied much like other complex systems. Attraction can strengthen or fade, outside pressures can push a relationship away from stability, and perhaps most importantly, there may be a critical mathematical threshold beyond which recovery becomes increasingly difficult.

In his new book, Love! Valour! Equations! The Mathematics of the Couple, published by CRC Press, Pujo-Menjouet draws on mathematical ecology, psychology, literature, and even film to explore why some couples weather years of conflict, stress, children, illness, and financial hardship while others gradually drift apart.

The goal isn’t to produce an equation that predicts who will fall in love with whom. Instead, Pujo-Menjouet treats relationships as dynamical systems—systems that change over time, respond to disturbances, and can move toward either stability or decline.

“There is no mysterious enchantment or magic potion. By now, that would be known,” Pujo-Menjouet writes in the book, which draws on mathematics, psychology, literature, and film. “Is all hope lost then? Certainly not. That is precisely where everything becomes interesting.”

From Rabbits to Relationships

The mathematical models Pujo-Menjouet uses originated in ecology. His work uses Malthusian growth models and the Lotka-Volterra equations, originally developed to describe population dynamics in animals such as rabbits. He also studies the Allee effect, a phenomenon that explains how populations struggle to recover if they drop below a particular size.

Pujo-Menjouet adapts these concepts to relationships, using the idea of a critical threshold to examine when a couple may become increasingly vulnerable to separation. He also draws on the research of psychologist John Gottman, who showed that relationship behaviors can be quantified as data.

“Just as we can predict population growth or endangered species, we can model the evolution of feelings within a couple,” Pujo-Menjouet explains. “We’re not trying to predict who you’ll fall in love with, we’re trying to understand why some couples remain stable despite life’s inevitable shocks while others slowly drift apart.”

A Threshold for Falling Apart

The basic idea is simple: a relationship may have a critical threshold, or minimum level of stability needed to keep the bond intact. Pujo-Menjouet’s model considers three main forces: mutual attraction, the gradual weakening of feelings over time, and each partner’s emotional response to the other.

“If your feelings fall below this threshold and stay there, the mathematics predicts an inevitable decline toward separation,” Pujo-Menjouet says. “However, understanding this threshold gives couples a powerful tool: they can recognize danger zones and take corrective action.”

These models emphasize how couples recover from drifting apart. The key question is not whether couples experience conflict, but whether they have the resilience to restore balance afterward.

“Life will always send its wolves: stress, illness, work, children, financial difficulties,” Pujo-Menjouet says, “mathematics helps us understand how to build the brick house rather than the straw one.”

Could AI Become Love’s Early-Warning System?

Researchers such as Pujo-Menjouet are considering whether they could combine these mathematical models with artificial intelligence to create an early-warning system for relationships. Such a system could detect the signs of instability before they become apparent to the people involved.

Pujo-Menjouet compares this method to a GPS for relationships, showing where a couple currently is, where its dynamics may be heading, and the various ways they could arrive at a healthier place. Although the models don’t decide who somebody will love, they can help explain how relationships evolve and what actions might help couples maintain their connection. Early detection of problems would allow partners to make changes before reaching a stage where recovery becomes unlikely.

Why Love Resists a Formula

Pujo-Menjouet admits that present-day mathematical models have limitations. Most of these models are based on data from Western relationships. In contrast, the factors that impact whether a relationship succeeds or fails can differ from one culture, religion, or generation to another. He points out that the model must account for additional factors to be applicable everywhere.

Human behavior also introduces unpredictability that mathematical models cannot fully account for. People can change their habits, strengthen their commitment, seek therapy, or otherwise alter the dynamics of a relationship in ways the equations cannot anticipate. The equations identify tendencies rather than determine an unavoidable outcome.

“Mathematics can illuminate patterns and provide guidance,” Pujo-Menjouet says, “but ultimately, the success of a relationship depends on two people choosing, every day, to nurture their connection. The equations can show you the path, but you still have to walk it together.”

Rats make an ultrasonic sound when they eat chocolate

14 September 2026 at 13:50

There’s nothing better than sinking your teeth into a sweet, creamy chocolate bar. Rats think so, too—and they may announce their chocolate-infused joy to the world at ultrasonic frequencies. 

Researchers have previously linked ultrasonic rat vocalizations with different emotional and motivational states in the animals, such as in reaction to rewarding stimuli. For example, the rodents vocalize in this way when eating something sweet. 

Now, a team of researchers in Japan have discovered that rats emit a particular ultrasonic vocalization while eating chocolate. Their findings are detailed in a study recently published in the journal eNeuro.

To come to this conclusion, the researchers compared ultrasonic vocalizations that rats emitted when they had access to chocolate, with those they made when they didn’t have access to the candy. The team also compared them with a chocolate-free control group of rats. Researchers then used AI to analyze the vocalizations’ acoustic features, identifying a distinct ultrasonic vocalization—officially 40 kHz inverted-U—strongly associated with chocolate snacking. 

“When rats eat something delicious such as chocolate, they emit a distinct ultrasonic call that humans cannot hear,” Koshi Murata, a study co-author and researcher at the University of Fukui, said in a statement. “This call drops sharply when the brain’s opioid ‘pleasure’ system is blocked. This suggests that rats may be vocally expressing the enjoyment of eating, offering a new window into whether animals experience pleasure as we do.”

To see if this distinct vocalization was related to the tastiness of food or just eating in general, Murata and colleagues compared chocolate-eating vocalizations with the sounds the rats produced while eating regular food. And while the rats ate similar amounts of both, they emitted significantly more 40 kHz inverted-U USVs while eating chocolate. 

In a separate food-choice test, the rats also demonstrated an obvious preference for chocolate: 15 out of 16 rats picked chocolate over the regular food (and can we blame them?). In two experiments, researchers also found that the vast majority of 40 kHz inverted-U USVs were emitted within one second of a feeding event. 

“Our discovery suggests that animal vocalizations could serve as a real-time, non-invasive readout of internal emotional states—specifically, how much an animal is enjoying its food,” said Murata. “Such a tool would allow researchers to measure ‘pleasure’ more directly than current methods permit, and could accelerate research into the brain mechanisms that generate positive emotions.” 

Understanding more about how the brain processes rewarding experiences could shed light on behaviors like overeating, as well as conditions like anhedonia, or the inability to feel pleasure and a common symptom of depression.

Smart elephants can look before they leap

9 September 2026 at 19:00

Like humans, elephants are famously social creatures. But unlike teenage humans, Asian elephants (Elephas maximus) can think before they act.

Scientists in Thailand discovered this after 16 Asian elephants at the country’s National Elephant Institute successfully participated in a detour test. In this sort of challenge, the animal has to resist an obvious but ineffective strategy (an impulse) to get a treat and follow an effective but indirect alternative—an ability called inhibitory control. 

“Although we are beginning to understand how intelligent elephants are, we still know very little about their capacity for inhibitory control,” Sydney Hope, a postdoctoral researcher at Hunter College in New York, tells Popular Science. “Understanding elephant inhibitory control will help us understand how this aspect of cognition may have evolved across species, including humans. It will also help us understand how elephants may cope with environmental—including anthropogenic—changes.”

Experiment Setup. (A) An elephant enters the “over” opening to gain access to food in a familiarization trial. (B) An elephant enters the “under” opening to gain access to food (apple) in a test trial. Photos were cropped to remove extraneous background material; the left image was mirrored.

Image: Photos by Sangpa Dittakul/Hope et al., 2026, PLOS One, CC-BY 4.0.

In their new study published today in the journal PLOS One, Hope and her colleagues presented Asian elephants with a transparent box filled with fruit. The box also had small holes, so that the elephants could see and smell the goodies inside. The temptation here was to reach directly through the barrier, whose holes were presumably too small for the elephants’ trunk to fit through. The elephants could consistently resist this impulse, and instead used an opening on the side of the box, as they had previously been taught to do. 

In a second version of the trial, the researchers rotated the box. Initially, the elephants gave in to the urge to reach for where the opening used to be, but then rapidly amended their behavior. This fix came slower in older elephants. That’s potentially because of cognitive decline with age, though the team says that further research is necessary on this point. 

More broadly, the study shows that elephants are able to resist an impulsive, ineffective action (like reaching through a perforated, transparent barrier or continuing a no longer successful approach) in favor of e indirect effective behaviors, even if they must change a previously effective strategy. And they’re in good company—inhibitory control is important for humans’ and other animals’ decision-making and cognitive flexibility. For elephants, it might play a significant role in their famous problem-solving and socializing capabilities, according to the researchers. 

“These results may also help conservation efforts,” Hope points out. “One major threat to Asian elephants is human-elephant conflict, often occurring when elephants navigate around barriers (e.g., electric fences) to enter agricultural lands. Understanding how elephants detour around barriers in controlled experiments may help with developing new techniques to mitigate conflict.”

Classic sitcom ‘Friends’ helps grad student endure 104 brain scans

9 September 2026 at 15:08

The science of getting Z’s has progressed rapidly in recent years. A growing body of research links poor sleep to increased risk of cognitive decline, a higher likelihood of Alzheimer’s disease, and even greater chances of developing heart problems. At the same time, wearables, like smart rings and watches, are transforming the way everyday people view sleep, turning their resting hours into rich datasets to pore over, sometimes to unhealthy obsessive levels. 

What’s still less understood, is how the subtle, everyday fluctuations in sleep quality that come from simply living a normal life can alter brain chemistry. People don’t live in controlled lab settings, and even the most avid bio-optimizer still has nights where quality sleep takes a backseat. Actually understanding how someone’s day-to-day sleep patterns affect their brain chemistry would require putting them in an MRI machine and collecting data over and over again, over long stretches of time to get a more holistic view. 

That’s exactly what Auburn University electrical and computer engineering graduate student Joshita Majumdar signed up for. Over 76 weeks, Majumdar slipped into the university’s 7-Tesla MRI scanner 104 times. That’s a level of commitment that would make even a stalwart Zen meditator fidget with frustrated boredom. Thankfully, Majumdar had a special companion to accompany her during the loud, cramped, 90-minute sessions: the hit television sitcom Friends.

Majumdar recalls how a screen in the machine would cycle through four 10-minute videos of the staple from the 90’s and early 2000’s, each made up of several different scenes clipped together. The idea was twofold. Majumdar needed something playing during the sessions that would keep her from getting bored, and Friends just happens to be her self-described “guilty pleasure.” It was also one of the first shows she connected with as an international student adjusting to her early days in the United States, so some scenes strike particularly nostalgic, emotional notes. And like any great sitcom, Friends runs the gamut from numbing brain-rot to tear-jerking sentimentality. That’s potentially a great backdrop for a study analyzing changes in brain chemistry.  

“If you’re happy, you watch Friends. If you’re sad, you watch Friends,” Majumdar tells Popular Science. “So all times [are] a good time to watch Friends, right?”

Past studies have looked at the way sleep variability affects brain chemistry, but many of those involve intentionally depriving the subject of sleep. This longer-term approach takes a more subtle approach that should better reflect the nuances of everyday life. 

“This is a person living her life, going through normal ups and downs and we are seeing how brain chemistry responds to that,” Majumdar’s advisor and Auburn University Electrical and Computer Engineering Professor Gopikrishna Deshpande said.  “That’s what makes this dataset so powerful. It’s not artificial. It’s not forced. It’s real.”

The journey to 104 brain scans 

Majumdar grew up in Kolkata, West Bengal, India, and moved to the U.S. in 2016 to pursue a master’s degree in engineering at the University of Georgia, with an emphasis on mechanical engineering. Early on, she became interested in how different environmental factors affect brain function. And while she was busy pushing forward with her rigorous academic work, she also dealt with occasional homesickness, living in a new country thousands of miles away from friends and relatives. 

Around that same time, Majumdar says she started watching Friends to see what all the fuss was about. People around her seemed obsessed with the show, but she hadn’t seen it, and initially didn’t really understand the hype. Eventually, she went back to the show with fresh eyes and everything clicked. The sarcastic Chandler Bing (Matthew Perry) and affable actor Joey Tribbiani (Matt LeBlanc) are among her favorite characters.

“I gave it another try, and then I was like, oh no, this is fun,” Majumdar said. “And then it became a guilty pleasure.” 

When it came time to pick a test subject for this new, lengthy MRI study, Majumdar says Dr. Deshpande asked her if she’d be up for volunteering. Majumdar has some experience with MRI machines from past projects, enough to know that she wasn’t prohibitively claustrophobic or bothered by the machine’s loud industrial noises. Still, nothing she’d done before this could compare to the endurance and commitment it would take to see this through. The team decided not to commit to a set number of scans at the onset, and took it day by day to see how much the grad student could handle. 

“We said, like, ‘Okay, we’ll take one day at a time, one week at a time, and see how far we can pull it through,” Majumdar explained. 

Don’t sleep on Friends  

Majumdar was the one who pitched playing Friends episodes in the machine. She compiled four 10-minute videos, each made up of different scenes from various episodes. The material ran the gamut in tone, with the goal of eliciting a range of brain responses. One particularly strategic choice was to include clips of episodes aired around Thanksgiving. These fan-favorites tend lean heavily on themes of family, friendship, and camaraderie. Friends, in other words, was meant to roughly simulate the backdrop for Majumdar’s everyday life brain state. 

“In a task-based MRI, we are giving a particular stimulus, so we kind of have an idea what we are trying to activate in the brain,”  Majumdar said. “But in a naturalistic run, it’’s kind of like you’re putting yourself into a real-world situation.”

But that wasn’t all. Every session, the team would also play a roughly four-minute music video to the song “Love You Zindagi,” from the 2016 Bollywood film Dear Zindagi. Similar to the Thanksgiving episodes, this video was thoughtfully selected for its depiction of friends and family. It also helps remind Majumdar of home. 

“I have left my friends and family back in India,” Majumdar said. “So depending upon what my emotions are on that day, I used to really connect to it differently each day.”

Majumdar and her colleagues quickly settled into a routine for their MRI odyssey. She would come to the university’s neuroimaging center on Tuesdays and Thursdays, typically around 7:30 in the evening. She had the choice of that later time slot or first thing in the morning, but chose the former because she says she isn’t really a morning person. That choice came with some trade-offs, though. 

Early on, she discovered that eating a meal immediately before entering the machine made her feel dizzy. After one fraught experience, she made a point of giving herself a gap of 90 minutes to two hours after eating before going into the scanner. Coming in later at night, especially after a long day of PhD work, also meant she sometimes had to fight the urge to fall asleep. Even though she was stuck in the machine for 90 minutes at a time, the tests required that she keep her eyes open for the vast majority of it. That struggle is partly what makes subsequent findings all the more interesting. 

“Sometimes I was a little bit sleepy, but that’s part of it,” Majumdar said. “And that’s the thing that we wanted to bring out through this research: that you are in a very natural setting. You’re not in a kind of a forced experiment where you are either sleep-deprived or put under some conditions that might evoke a different brain response. We really wanted to look at the real-world condition where I’m just living my life, and in parallel I’m getting scanned and seeing how the brain chemistry responds to it.”

In addition to sitting in the MRI machine, Majumdar logged everything she ate and wore a sleep-tracking ring. With all of that data, the team was able to match each night’s sleep metrics with the next day’s scan and compare patterns over time. Though there’s still data being combed through, they’ve already found an important connection: across the 104 sessions collected over 76 weeks, nights with less deep sleep and more light sleep tended to be followed by higher glutamate levels the next day. Glutamate is an amino acid that acts as a kind of chemical messenger in the brain. In a previous university blog post, Majumdar compared this finding to the brain flushing out byproducts that build up during active, wakeful moments, allowing for a more restful night’s sleep.

“You wake up with a fresh mind,” she said. “But if that process is blocked, it’s going to hamper you the next day.”

But is she sick of sipping coffee at Central Perk?

Majumdar’s work in this area has only just begun. Moving forward, she and her colleagues hope to bring on more study participants  to make the dataset even richer, though they’ll likely make adjustments so that each participant doesn’t have to go in for scans quite as often as she did. 

Eventually, she says she also hopes to use AI and other tools to try and extract the feelings and emotions experienced during those MRI sessions (and during certain Friends’ moments) to get a better sense of what’s happening in the brain when certain feelings are evoked. 

Miraculously, even after watching the show in a cramped, rumbling tube for 18 months, Majumdar says she still isn’t sick of Friends. When asked if she can still watch the silly sitcom without getting bored, Majumdar responds with an emphatic, 

“Yes, definitely.”

Inside the Mind of a Billionaire Cheater: “At His Level of Wealth, Societal Ethics No Longer Register”

5 September 2026 at 14:26

Almost exactly one year ago, investigative journalist Pablo Torre, host of the Pablo Torre Finds Out podcast, exposed alleged efforts by Los Angeles Clippers billionaire owner Steve Ballmer (a former Microsoft Executive) to circumvent the NBA’s collective bargaining agreement by funneling undisclosed millions of dollars to All-Star player Kawhi Leonard.

Now, the league’s year-long investigation has concluded, revealing even more violations than the Pulitzer Prize– and Edward R. Murrow Award-winning podcast series uncovered over more than a dozen episodes.

The investigation’s conclusion also saw league Commissioner Adam Silver levy drastic punishments, including the loss of five future draft picks and suspensions for Ballmer and others in upper management. The team also received a league-record $30 million fine.

As the fallout from the historic cheating scandal and threats of legal action from the team owner continue to make headlines, The Debrief asked experts to help explain the mindset and decision-making of people like Ballmer, who operate in the rare universe of someone reportedly worth over $140 billion.

Decision Making at the Top

To understand how such a wealthy and successful individual could break the rules as brazenly as the 35-page public report from investigating law firm Wachtel, Lipton, Rosen, and Katz lays out, The Debrief asked Patrick Vishy, a behavioral finance educator specializing in decision-making and risk perception for high-level investors and traders, to offer some insight.

“People at the $100 billion level like Steve don’t see risk the same way we do, because survival is no longer on the table,” Vishy explained. “It now becomes a scoreboard amongst his industry peers.”

The high finance educator also suggested that many of Balmer’s fellow owners likely “respected the creativity behind his rule-breaking.” However, Vishy noted, they were likely less enthusiastic about “how he allowed himself to get caught.”

Although the No Nonsense Courses finance educator does not have a psychology background, he did point to two well-documented ‘internal reasons’ why he believes that “Steve in particular is bending the rules the way he has and will probably continue to.”

Invincibility Bias

The first is a concept the educator called “Invincibility Bias.” A search of relevant psychological documentation found that this bias, which is more often referred to as an “invulnerability bias,” is typically associated with the normal teenage developmental idea of being immortal or invulnerable to danger.

In a November 2025 story for Psychology Today, Dr. Su Yeong Kim, Ph.D., described invulnerability bias in teens as “the quiet conviction that ‘nothing bad will happen to me.’”

“This mindset differs from confidence, which acknowledges risk but trusts in one’s ability to handle it,” Dr. Kim explained. “Invulnerability, by contrast, denies risk altogether.”

Although the Clippers owner is well past his teenage years, Vishy told The Debrief that it is not uncommon to encounter this mindset in extremely high-net-worth individuals like Ballmer.

“When somebody takes asymmetrical risks for decades and constantly wins, their brain internalizes the belief that standard rules are meant for others, not them, and they can engineer their way out of any consequence,” the finance educator explained.

The Level Playing Field Fallacy

The second mechanism Vishy suggested that may have affected Balmer’s decisions to cheat is called “The Level Playing Field Fallacy.” While most online citations say the concept originated in sports, its primary modern use appears to be in finance.

When explaining how it applies to this situation involving both worlds, Vishy told The Debrief that “Steve can reasonably assume rival team owners are bending the rules as well and does not want to put himself at such a voluntary disadvantage by being 100% clean.”

As a matter of fact, Vishy added, for someone at Ballmer’s level of success, “it would seem absurd even.”

“At his level of wealth, societal ethics no longer register as a meaningful constraint,” the finance educator explained. “His competitive drive won’t allow him to constantly play from behind like that.”

“These two things lead to ego-driven moral disengagement,” Vishy added. “When you’re used to being the smartest guy in the room, the inner monologue regarding internal ethics shifts from ‘Is this allowed?’ to ‘Is this necessary for my goal?’ plain and simple.”

Why Do Subordinates Go Along?

A thorough examination of the Wachtel report reveals more than a single, uber-wealthy individual deciding that the rules don’t apply to him and that everyone else is cheating, so why shouldn’t he? Instead, the year-long investigation uncovered several cases of fraud involving at least four outside companies and a handful of top Clippers executives all working in concert to facilitate the deception.

While the financial motivations for companies trying to win contracts or unscrupulous agents like Kawhi’s notorious “Uncle Dennis” (who the league has banned for five years as part of its ruling) seem relatively straightforward, the mindset of high-level Clippers employees is not as clear.

According to the investigation’s findings, several Clippers higher-ups, including the team’s President of Business Affairs, Gillian Zucker, and LA’s President of Basketball Operations, Lawrence Frank, not only repeatedly and blatantly violated the league’s salary cap circumvention rules, but also preemptively constructed a series of cover stories just in case a future investigation ever took place.

After a 12-month suspension for Zucker and a 6-month suspension for Frank, The Debrief contacted Giulia P. Davis, a 15-year management consulting veteran and former equity partner who works with Fortune 500 clients to understand the “go along” mindset that may have permeated the entire organization.

The People Involved Often Don’t Experience Themselves as Breaking the Rules

According to the Founder of Mycelia Therapy, the reasons people working under a Steve Ballmer-type go along with rule-breaking behaviors often go beyond a simple fear of losing their jobs. Instead, Davis explained without directly addressing the Clippers fiasco, “there’s a pattern I find interesting in situations like this.”

“The people involved often don’t experience themselves as breaking the rules,” the Licensed Marriage and Family Therapist (LMFT) told The Debrief. “They believe they’ve found a way to work within them.”

As an example, the veteran management consultant pointed to the language used by individuals who find themselves in these situations

“The defense is often not ‘we didn’t do this,’ but ‘what we did was legal,’ Davis explained.

How People Convince Themselves that They Are Not a Rule Breaker

When exploring potential motivations for high-level subordinates, Davis also told The Debrief that people who go along with bad behavior at these levels don’t always start out with improper intentions. Instead, the therapist noted, advisors, lawyers, and outside consultants “will sometimes come into an organization looking for solutions.”

“While saying no might not be their ultimate goal, they must determine whether something can work,” she explained.

The finance world veteran also noted that simple inertia and lack of consequences can lead to a more permissive mentality.

“When all of those people in the room are going to get paid regardless of what happens, it’s quite surprising how easily one can lose sight of a much larger issue,” Davis explained, adding, “that’s why I believe the primary issue might be systemic (i.e., structural), not solely due to the individual’s nature.”

For example, Davis said it is possible for someone in a leadership or ownership position like Ballmer to “develop a culture within which all individuals technically comply with their respective roles, yet no member of the organization will have sufficient separation or motivation to say, ‘I did my job, but in doing so, I defeated the intent of this policy.’”

“It is that point in the decision-making process where ego appears,” Davis said.

“In other words, once you see yourself as being a person who follows the rules, it is far easier for you to deny your own admission, as you are now defending a personal identity,” Davis concluded.
