Misinformation lends itself to social contagion – here’s how to recognize and combat it

In 2019, a rare and shocking event in the Malaysian peninsula town of Ketereh grabbed international headlines. Nearly 40 girls age 12 to 18 from a religious school had been screaming inconsolably, claiming to have seen a “face of pure evil,” complete with images of blood and gore. Experts believe that the girls suffered what is known as a mass psychogenic illness, a psychological condition that results in physical symptoms and spreads socially – much like a virus. I’m a social and behavioral scientist within the field of public health. I study the ways in which individual behavior is influenced by prevailing social norms and social network processes, across a wide range of behaviors and contexts. Part of my work involves figuring out how to combat the spread of harmful content that can shape our behavior for the worse, such as misinformation. Mass psychogenic illness is not misinformation, but it gives researchers like me some idea about how misinformation spreads. Social connections establish pathways of influence that can facilitate the spread of germs, mental illness and even behaviors. We can be profoundly influenced by others within our social networks, for better or for worse.

The spreading of social norms

Researchers in my field think of social norms as perceptions of how common and how approved a specific behavior is within a specific network of people who matter to us. These perceptions may not always reflect reality, such as when people overestimate or underestimate how common their viewpoint is within a group. But they can influence our behavior nonetheless. For many, perception is reality. Social norms and related behaviors can spread through social networks like a virus can, but with one crucial caveat. Viruses often require just one contact with a potential host to spread, whereas behaviors often require multiple contacts to spread. This phenomenon, known as complex contagion, highlights how socially learned behaviors take time to embed.
Watch the people in this video and see how you react.

Fiction spreads faster than fact

Consider a familiar scenario: the return of baggy jeans to the fashion zeitgeist. For many millennials like me, you may react to a friend engaging in this resurrected trend by cringing and lightly teasing them. Yet, after seeing them don those denim parachutes on multiple occasions, a brazen thought may emerge: “Hmm, maybe they don’t look that bad. I could probably pull those off.” That’s complex contagion at work. This dynamic is even more evident on social media. One of my former students expressed this succinctly. She was looking at an Instagram post about Astro Boy Boots – red, oversize boots based on those worn by a 1952 Japanese cartoon character. Her initial skepticism quickly faded upon reading the comments. As she put it, “I thought they were ugly at first, but after reading the comments, I guess they’re kind of fire.” Moving from innocuous examples, consider the spread of misinformation on social media. Misinformation is false information that is spread unintentionally, while disinformation is false information that is intentionally disseminated to deceive or do serious harm. Research shows that both misinformation and disinformation spread faster and farther than truth online. This means that before people can muster the resources to debunk the false information that has seeped into their social networks, they may have already lost the race. Complex contagion may have taken hold, in a malicious way, and begun spreading falsehood throughout the network at a rapid pace. People spread false information for various reasons, such as to advance their personal agenda or narrative, which can lead to echo chambers that filter out accurate information contrary to one’s own views. Even when people do not intend to spread false information online, doing so tends to happen because of a lack of attention paid to accuracy or lower levels of digital media literacy.

Inoculation against social contagion

So how much can people do about this? One way to combat harmful contagion is to draw on an idea first used in the 1960s called pre-bunking. The idea is to train people to practice skills to spot and resist misinformation and disinformation on a smaller scale before they’re exposed to the real thing. The idea is akin to vaccines that build immunity through exposure to a weakened form of the disease-causing germ. The idea is for someone to be exposed to a limited amount of false information, say through the pre-bunking with Google quiz. They then learn to spot common manipulation tactics used in false information and learn how to resist their influence with evidence-based strategies to counter the falsehoods. This could also be done using a trained facilitator within classrooms, workplaces or other groups, including virtual communities. Then, the idea is to gradually repeat the process with larger doses of false information and further counterarguments. By role-playing and practicing the counterarguments, this resistance skills training provides a sort of psychological innoculation against misinformation and disinformation, at least temporarily. Importantly, this approach is intended for someone who has not yet been exposed to false information – hence, pre-bunking rather than debunking. If we want to engage with someone who firmly believes in their stance, particularly when it runs contrary to our own, behavioral scientists recommend leading with empathy and nonjudgmentally exchanging narratives. Debunking is difficult work, however, and even strong debunking messages can result in the persistence of misinformation. You may not change the other person’s mind, but you may be able to engage in a civil discussion and avoid pushing them further away from your position.

Spreading facts, not fiction

When everyday people apply this with their friends and loved ones, they can train people to recognize the telltale signs of false information. This might be recognizing what’s known as a false dichotomy – for instance, “either you support this bill or you HATE our country.” Another signal of false information is the common tactic of scapegoating: “Oil industry faces collapse due to rise in electric car ownership.” And another is the slippery slope of logical fallacy. An example is “legalization of marijuana will lead to everyone using heroin.” All of these are examples of common tactics that spread misinformation and come from a Practical Guide to Pre-Bunking Misinformation, created by a collaborative team from the University of Cambridge, BBC Media Action and Jigsaw, an interdisciplinary think tank within Google. This approach is not only effective in combating misinformation and disinformation, but also in delaying or preventing the onset of harmful behaviors. My own research suggests that pre-bunking can be used effectively to delay the initiation of tobacco use among adolescents. But it only works with regular “booster shots” of training, or the effect fades away in a matter of months or less. Many researchers like me who study these social contagion dynamics don’t yet know the best way to keep these “booster shots” going in people’s lives. But there are recent studies showing that it can be done. A promising line of research also suggests that a group-based approach can be effective in maintaining the pre-bunking effects to achieve psychological herd immunity. Personally, I would bet my money on group-based approaches where you, your friends or your family can mutually reinforce each other’s capacity to resist harmful social norms entering your network. Simply put, if multiple members of your social network have strong resistance skills, then your group has a better chance of resisting the incursion of harmful norms and behaviors into your network than if it’s just you resisting alone. Other people matter. In the end, whether we’re empowering people to resist the insidious creep of online falsehoods or equipping adolescents to stand firm against peer pressure to smoke or use other substances, the research is clear: Resistance skills training can provide an essential weapon for safeguarding ourselves and young people from harmful behaviors.

The Long Track Back

Why Downtown Los Angeles Feels Small Compared to Other Cities

Downtown Los Angeles often feels “small” compared to other U.S. cities, but that’s only part of the story. With some of the tallest buildings west of the Mississippi and skyline clusters spread across the region, LA’s downtown reflects the city’s unique polycentric identity—one that, if combined, could form a true mega downtown.

Downtown Los Angeles

When people think of major American cities, they often imagine a bustling, concentrated downtown core filled with skyscrapers. New York has Manhattan, Chicago has the Loop, San Francisco has its Financial District. Los Angeles, by contrast, often leaves visitors surprised: “Is this really downtown?”

The answer is yes—and no.

Downtown LA in Context

Compared to other major cities, Downtown Los Angeles (DTLA) is relatively small as a central business district. For much of the 20th century, strict height restrictions capped most buildings under 150 feet, while cities like Chicago and New York were erecting early skyscrapers. LA’s skyline didn’t really begin to climb until the late 1960s.

But history alone doesn’t explain why DTLA feels different. The real story lies in how Los Angeles grew: not as one unified city center, but as a collection of many hubs.

Downtown Los Angeles

Downtown Los Angeles

A Polycentric City

Los Angeles is famously decentralized. Hollywood developed around the film industry. Century City rose on former studio land as a business hub. Burbank became a studio and aerospace center. Long Beach grew around the port. The Wilshire Corridor filled with office towers and condos.

Unlike other cities where downtown is the place for work, culture, and finance, Los Angeles spread its energy outward. Freeways and car culture made it easy for businesses and residents to operate outside of downtown. The result is a polycentric metropolis, with multiple “downtowns” rather than one dominant core.

A Resident’s Perspective

As someone who lived in Los Angeles for 28 years, I see DTLA differently. While some outsiders describe it as “small,” the reality is that Downtown Los Angeles is still significant. It has some of the tallest buildings west of the Mississippi River, including the Wilshire Grand Center and the U.S. Bank Tower. Over the last two decades, adaptive reuse projects have transformed old office buildings into lofts, while developments like LA Live, Crypto.com Arena, and the Broad Museum have revitalized the area.

In other words, DTLA is large enough—it just plays a different role than downtowns in other American cities.

The “Mega Downtown” That Isn’t

A friend once put it to me with a bit of imagination: “If you could magically pick up all of LA’s skyline clusters—Downtown, Century City, Hollywood, the Wilshire Corridor—and drop them together in one spot, you’d have a mega downtown.”

He’s right. Los Angeles doesn’t lack tall buildings or urban energy—it just spreads them out over a vast area, reflecting the city’s unique history, geography, and culture.

A Downtown That Fits Its City

So, is Downtown LA “small”? Compared to Manhattan or Chicago’s Loop, yes. But judged on its own terms, DTLA is a vibrant hub within a much larger, decentralized metropolis. It’s a downtown that reflects Los Angeles itself: sprawling, diverse, and impossible to fit neatly into the mold of other American cities.

How a 22-year-old George Washington learned how to lead, from a series of mistakes in the Pennsylvania wilderness

This Presidents Day, I’ve been thinking about George Washington − not at his finest hour, but possibly at his worst.

This Presidents Day, I’ve been thinking about George Washington − not at his finest hour, but possibly at his worst.

In 1754, a 22-year-old Washington marched into the wilderness surrounding Pittsburgh with more ambition than sense. He volunteered to travel to the Ohio Valley on a mission to deliver a letter from Robert Dinwiddie, governor of Virginia, to the commander of French troops in the Ohio territory. This military mission sparked an international war, cost him his first command and taught him lessons that would shape the American Revolution.

As a professor of early American history who has written two books on the American Revolution, I’ve learned that Washington’s time spent in the Fort Duquesne area taught him valuable lessons about frontier warfare, international diplomacy and personal resilience.

The mission to expel the French

In 1753, Dinwiddie decided to expel French fur trappers and military forces from the strategic confluence of three mighty waterways that crisscrossed the interior of the continent: the Allegheny, Monongahela and Ohio rivers. This confluence is where downtown Pittsburgh now stands, but at the time it was wilderness.

King George II authorized Dinwiddie to use force, if necessary, to secure lands that Virginia was claiming as its own.

As a major in the Virginia provincial militia, Washington wanted the assignment to deliver Dinwiddie’s demand that the French retreat. He believe the assignment would secure him a British army commission.

Washington received his marching orders on Oct. 31, 1753. He traveled to Fort Le Boeuf in northwestern Pennsylvania and returned a month later with a polite but firm “no” from the French.

Dinwiddie promoted Washington from major to lieutenant colonel and ordered him to return to the Ohio River Valley in April 1754 with 160 men. Washington quickly learned that French forces of about 500 men had already constructed the formidable Fort Duquesne at the forks of the Ohio. It was at this point that he faced his first major test as a military leader. Instead of falling back to gather more substantial reinforcements, he pushed forward. This decision reflected an aggressive, perhaps naive, brand of leadership characterized by a desire for action over caution.

Washington’s initial confidence was high. He famously wrote to his brother that there was “something charming” in the sound of whistling bullets.

The Jumonville affair and an international crisis

Perhaps the most controversial moment of Washington’s early leadership occurred on May 28, 1754, about 40 miles south of Fort Duquesne. Guided by the Seneca leader Tanacharison – known as the “Half King” – and 12 Seneca warriors, Washington and his detachment of 40 militiamen ambushed a party of 35 French Canadian militiamen led by Ensign Joseph Coulon de Jumonville. The Jumonville affair lasted only 15 minutes, but its repercussions were global.

Ten of the French, including Jumonville, were killed. Washington’s inability to control his Native American allies – the Seneca warriors executed Jumonville – exposed a critical gap in his early leadership. He lacked the ability to manage the volatile intercultural alliances necessary for frontier warfare.

Washington also allowed one enemy soldier to escape to warn Fort Duquesne. This skirmish effectively ignited the French and Indian War, and Washington found himself at the center of a burgeoning international crisis.

Defeat at Fort Necessity

Washington then made the fateful decision to dig in and call for reinforcements instead of retreating in the face of inevitable French retaliation. Reinforcements arrived: 200 Virginia militiamen and 100 British regulars. They brought news from Dinwiddie: congratulations on Washington’s victory and his promotion to colonel.

His inexperience showed in his design of Fort Necessity. He positioned the small, circular palisade in a meadow depression, where surrounding wooded high ground allowed enemy marksmen to fire down with impunity. Worse still, Tanacharison, disillusioned with Washington’s leadership and the British failure to follow through with promised support, had already departed with his warriors weeks earlier. When the French and their Native American allies finally attacked on July 3, heavy rains flooded the shallow trenches, soaking gunpowder and leaving Washington’s men vulnerable inside their poorly designed fortification.

The battle of Fort Necessity was a grueling, daylong engagement in the mud and rain. Approximately 700 French and Native American allies surrounded the combined force of 460 Virginian militiamen and British regulars. Despite being outnumbered and outmaneuvered, Washington maintained order among his demoralized troops. When French commander Louis Coulon de Villiers – Jumonville’s brother – offered a truce, Washington faced the most humbling moment of his young life: the necessity of surrender. His decision to capitulate was a pragmatic act of leadership that prioritized the survival of his men over personal honor.

The surrender also included a stinging lesson in the nuances of diplomacy. Because Washington could not read French, he signed a document that used the word “l’assassinat,” which translates to “assassination,” to describe Jumonville’s death. This inadvertent admission that he had ordered the assassination of a French diplomat became propaganda for the French, teaching Washington the vital importance of optics in international relations.

Lessons that forged a leader

The 1754 campaign ended in a full retreat to Virginia, and Washington resigned his commission shortly thereafter. Yet, this period was essential in transforming Washington from a man seeking personal glory into one who understood the weight of responsibility.

He learned that leadership required more than courage – it demanded understanding of terrain, cultural awareness of allies and enemies, and political acumen. The strategic importance of the Ohio River Valley, a gateway to the continental interior and vast fur-trading networks, made these lessons all the more significant.

Ultimately, the hard lessons Washington learned at the threshold of Fort Duquesne in 1754 provided the foundational experience for his later role as commander in chief of the Continental Army. The decisions he made in Pennsylvania and the Ohio wilderness, including the impulsive attack, the poor choice of defensive ground and the diplomatic oversight, were the very errors he would spend the rest of his military career correcting.

Though he did not capture Fort Duquesne in 1754, the young George Washington left the woods of Pennsylvania with a far more valuable prize: the tempered, resilient spirit of a leader who had learned from his mistakes.

The Building That Proved Los Angeles Could Go Vertical

Los Angeles once banned skyscrapers, yet City Hall broke the height limit and proved high-rise buildings could be engineered safely in an earthquake zone.

Published

How City Hall Quietly Undermined LA’s Own Height Limits

The Knowledge Series | STM Daily News

For more than half a century, Los Angeles enforced one of the strictest building height limits in the United States. Beginning in 1905, most buildings were capped at 150 feet, shaping a city that grew outward rather than upward.

The goal was clear: avoid the congestion, shadows, and fire dangers associated with dense Eastern cities. Los Angeles sold itself as open, sunlit, and horizontal — a place where growth spread across land, not into the sky.

And yet, in 1928, Los Angeles City Hall rose to 454 feet, towering over the city like a contradiction in concrete.

It wasn’t built to spark a commercial skyscraper boom.
But it ended up proving that Los Angeles could safely build one.


A Rule Designed to Prevent a Manhattan-Style City

The original height restriction was rooted in early 20th-century fears:

  • Limited firefighting capabilities
  • Concerns over blocked sunlight and airflow
  • Anxiety about congestion and overcrowding
  • A strong desire not to resemble New York or Chicago

Los Angeles wanted prosperity — just not vertical density.

The height cap reinforced a development model where:

  • Office districts stayed low-rise
  • Growth moved outward
  • Automobiles became essential
  • Downtown never consolidated into a dense core

This philosophy held firm even as other American cities raced upward.


@stmblog

Los Angeles banned skyscrapers for decades — except one. 🏛️ While most buildings were capped at 150 feet, LA City Hall rose three times higher. This wasn’t a loophole — it was power, symbolism, and city planning shaping the skyline we know today. Why was City Hall the exception? And how did this one decision change Los Angeles forever? 📍 Forgotten LA 🧠 The Knowledge Series 📰 STM Daily News LosAngelesHistory LACityHall ForgottenLA UrbanPlanning CityPlanning LASkyline DidYouKnow HistoryTok TheKnowledge STMDailyNews ♬ original sound – STMDailyNews – STMDailyNews


Why City Hall Was Never Meant to Change the Rules

City Hall was intentionally exempt from the height limit because the law applied primarily to private commercial buildings, not civic monuments.

But city leaders were explicit about one thing:
City Hall was not a precedent.

It was designed to:

  • Serve as a symbolic seat of government
  • Stand alone as a civic landmark
  • Represent stability, authority, and modern governance
  • Avoid competing with private office buildings

In effect, Los Angeles wanted a skyline icon — without a skyline.


Innovation Hidden in Plain Sight

What made City Hall truly significant wasn’t just its height — it was how it was built.

At a time when seismic science was still developing, City Hall incorporated advanced structural ideas for its era:

  • A steel-frame skeleton designed for flexibility
  • Reinforced concrete shear walls for lateral strength
  • A tapered tower to reduce wind and seismic stress
  • Thick structural cores that distributed force instead of resisting it rigidly

These choices weren’t about aesthetics — they were about survival.


The Earthquake That Changed the Conversation

In 1933, the Long Beach earthquake struck Southern California, causing widespread damage and reshaping building codes statewide.

Los Angeles City Hall survived with minimal structural damage.

This moment quietly reshaped the debate:

  • A tall building had endured a major earthquake
  • Structural engineering had proven effective
  • Height alone was no longer the enemy — poor design was

City Hall didn’t just survive — it validated a new approach to vertical construction in seismic regions.


Proof Without Permission

Despite this success, Los Angeles did not rush to repeal its height limits.

Cultural resistance to density remained strong, and developers continued to build outward rather than upward. But the technical argument had already been settled.

City Hall stood as living proof that:

  • High-rise buildings could be engineered safely in Los Angeles
  • Earthquakes were a challenge, not a barrier
  • Fire, structural, and seismic risks could be managed

The height restriction was no longer about safety — it was about philosophy.


The Ironic Legacy

When Los Angeles finally lifted its height limit in 1957, the city did not suddenly erupt into skyscrapers. The habit of building outward was already deeply entrenched.

The result:

  • A skyline that arrived decades late
  • Uneven density across the region
  • Multiple business centers instead of one core
  • Housing and transit challenges baked into the city’s growth pattern

City Hall never triggered a skyscraper boom — but it quietly made one possible.


Why This Still Matters

Today, Los Angeles continues to wrestle with:

  • Housing shortages
  • Transit-oriented development debates
  • Height and zoning battles near rail corridors
  • Resistance to density in a growing city

These debates didn’t begin recently.

They trace back to a single contradiction: a city that banned tall buildings — while proving they could be built safely all along.

Los Angeles City Hall wasn’t just a monument.
It was a test case — and it passed.
