Every week of 2025 seems to bring a new health headline, whether it’s about climbing autism rates, changing vaccination recommendations or unexpected cancer risks.

For people trying to make informed choices about their own health and that of their families, it can be tough to make sense of it all. The science can feel contradictory and confusing. Human data is messy, and studies often yield conflicting results.

Sparring between government officials and scientists can muddy the picture further.

As professors who teach epidemiology and research methods to public health students, we start our students off with a few key questions that can help make sense of the evidence. We’ve come to realize that these lessons aren’t just for public health experts – they are tools that anyone can use to cut through bias, evaluate health claims and better understand health-related policy debates.

So next time you read a news article making a claim about a particular health condition, ask yourself these three questions.

No. 1: Are people getting this illness more often?

Media reports often highlight changes in how frequently a condition is diagnosed. Take, for example, “Autism rates in US rise again to 1 in 31 kids, CDC says,” and “CDC finds nearly 1 in 3 US youth have prediabetes, but experts question scant data.”

Before raising the alarm about an unfolding epidemic, it’s important to consider whether the changes in rates are due to what public health researchers call artifactual changes or if they are true changes.

Artifactual changes can occur even when the rate of a disease or condition in the population has not actually changed. When researchers revise how they define a particular condition, the number of people counted as having it can change over time. Autism rates, for example, have increased at least partially due to an expanded definition of autism.

Another example is a change in what classifies someone as having high blood pressure. In 2017, the American Heart Association lowered the cutoff for diagnosing hypertension from 140/90 to 130/80. As a result, almost overnight, more people were considered to have the condition.

A condition’s rate can also appear to increase when doctors become better at detecting it. The widespread adoption of the PSA test, short for prostate-specific antigen test, a blood test for prostate cancer detection, in the early 1990s resulted in a surge in prostate cancer diagnoses. Some fraction of these cases were detected at such an early stage that they may never have progressed to cause illness or death during the patient’s lifetime.

Increased awareness of a condition due to media reports or public discussion can also result in more diagnoses. That’s especially true when diagnosis is not based on a definitive medical test but instead on clinical observations or reports. For example, increases in ADHD cases over time may partly reflect increased recognition and diagnosis as awareness grows.

True changes in the rates of a disease or health condition reflect real shifts in the factors that cause a condition to become more or less common in a population.

A classic example of a true change in a disease rate is smoking and lung cancer. Early in the 1900s, lung cancer was a rare disease in the United States. By the 1930s, doctors were noticing more cases in men, leading to studies investigating its potential causes, including smoking.

Based on the results of numerous studies reviewed by the U.S. surgeon general’s Advisory Committee on Smoking and Health in the early 1960s, the committee concluded that smoking was a primary cause of lung cancer. In the surgeon general’s landmark report published in 1964, which drew upon evidence from over 7,000 scientific and technical articles, the committee concluded that “cigarette smoking contributes substantially to mortality from certain specific diseases and the overall death rate.”

No. 2: What kind of study led to this claim?

The strongest studies compare a control group, which does not receive the intervention being tested, and an experimental group, which does. Study participants are randomly assigned to one of these groups. This type of study design, called a randomized controlled trial, is considered the gold standard for proving when a treatment or other factor truly causes or prevents a disease.

However, a randomized controlled trial cannot be used to study potentially harmful factors such as pesticides or other chemicals found in our everyday environments. Exposing people to potentially harmful exposures would not be ethical. Instead, researchers need to rely on observational studies, which identify people who are already exposed to some factor in their daily lives – for example, those who work with pesticides – and compare their health outcomes to people who are not exposed to pesticides.

The challenge with observational studies is that the two groups of people often differ in unpredictable ways – and these differences might partly explain why one group has a higher rate of a certain disease or health condition. This is known as confounding. Statistical methods used to control for these differences between the groups are often imperfect. This is why it’s risky to draw conclusions from a single study.

No. 3: What other evidence is there?

Because a single study cannot prove cause and effect, experts review the total body of research on a topic, like a jury weighing all the testimony before rendering a verdict. Evidence often includes a combination of study types, including randomized clinical trials, observational studies and laboratory research. Randomized clinical trials test whether an intervention actually changes outcomes under controlled conditions, while observational studies look for patterns and associations in real-world populations. Laboratory research aims to uncover biological mechanisms linking a potential cause to a disease, and it is usually conducted under artificial circumstances.

For example, many studies have investigated the effects of chemicals in cigarette smoke. On balance, they have found that such chemicals cause cancer by damaging genetic material in lung cells. When this damage affects key genes, it can trigger the cells to divide uncontrollably and lead to the development of cancer.

Once scientists rule out explanations based in artifacts such as more people being classified with a condition due to changing definitions, they can combine evidence from a range of studies on a topic to build a convincing case for whether the factor they are investigating truly causes or prevents a disease or other condition. They weigh all the evidence because no single study settles the question, but together the pieces form a clearer picture.

The bottom line? If you see a health claim that seems too good – or too bad – to be true, take a moment to mentally run the evidence through these three questions before deciding what to believe.

People abused by intimate partners have worse asthma – but researchers are still untangling the reasons behind this surprising link

Source: The Conversation – USA (3) – By Anne P. DePrince, Professor of Psychology, University of Denver

Most drug treatments on the market today target inflammation, but a new approach may be needed. aquaArts studio/E+ via Getty Images

Asthma is a common, serious and difficult-to-manage chronic health condition. In the U.S., 1 in 7 people are diagnosed with asthma, and that number is rising.

Over the years, researchers have identified a mix of individual and environmental factors that play a role in asthma. For instance, obesity and alcohol use increase a person’s risk for asthma. And more extreme weather is linked to worse asthma symptoms.

In that mix of research, a new pattern has emerged pointing to links between asthma and abuse by a current or former romantic partner. As surprising as that might sound, these links are important because intimate partner abuse is common in the U.S. An estimated 47% of women and 44% of men are physically or sexually victimized or stalked by intimate partners at some point in their lives.

As a psychologist and an asthma specialist, we have teamed up to learn more about asthma and intimate partner abuse.

And what we’re seeing has important implications for treatment.

The role of inflammation

To understand how factors such as obesity or extreme weather can result in asthma, researchers have focused on inflammation. Inflammation plays a key role in keeping humans and other animals healthy.

When pathogens such as viruses attack the body, or the body suffers an injury, the immune system responds with inflammation. This immediate, short-term response helps the body minimize damage to cells and fight infection. It’s also what causes the red hotness that surrounds a skin injury or bothersome symptoms when fighting a cold.

While short-term inflammation is critical to good health, the inflammation system can go awry. Chronic inflammation contributes to many kinds of diseases, including asthma.

Uncontrolled inflammation drives asthma development and symptoms. Over the years, a better understanding of different types of inflammation that can worsen asthma has led to the identification of critical targets for asthma medications and important advances in care.

Because of this inflammation-asthma connection, most drug treatments for asthma today target overactive inflammation in the airways.

Looking for other explanations

Despite significant advances in drug treatments for asthma, a majority of adults with the condition have uncontrolled asthma, which means more flare-ups and an increased chance of dying from the disease.

As researchers and medical providers have figured out that not everyone responds to common medications, they’ve turned to more personalized approaches to understanding asthma predictors.

That more personalized approach led one of us, Dr. Wang, to wonder whether intimate partner abuse might play a role in asthma for some of her patients. After all, intimate partner abuse is linked with a host of health problems and health care costs.

Using a large database that was representative of the U.S. population, one of us (Dr. Wang) led a team in 2021 that discovered intimate partner abuse was associated with worsened asthma attacks and symptoms. That study included over 2,600 adults and found that having asthma along with a history of intimate partner abuse meant significantly greater odds of asthma attacks, more frequent symptoms and greater impact of symptoms on daily life.

This pattern was true even for adults who were out of the abusive relationships for a year or more, suggesting a persistent effect of intimate partner abuse on asthma.

Over time, other research teams also found links between intimate partner abuse and increased rates of having or developing asthma for adults.

In addition, research showed that intimate partner abuse also affects the next generation. Multiple studies have shown increased rates of asthma in children of women who were abused by their intimate partners.

A new view of inflammation

So, does this mean that intimate partner abuse leads to chronic overinflammation, which in turn causes asthma? Not necessarily, according to another study we did.

We worked with a team of researchers to recruit 60 adults with uncontrolled asthma into our study and examined many different markers of inflammation in the blood. Importantly, about half of those adults told us they had been abused by an intimate partner at some time in their lives. And about half said they had not.

First, we looked at the traditional types of inflammation studied in prior asthma research, including those targeted by currently available treatments. On measure after measure, our team found that patients with histories of intimate partner abuse had lower inflammation than those without histories of abuse, despite having uncontrolled asthma.

Surprised by this finding, we tested whether other factors that have been linked with asthma could better explain what we found. However, the pattern was still there – even when we took into account factors such as gender, obesity, anxiety and depression.

Next, we looked closely at the histories of abuse that patients reported. Most were out of the abusive relationship for more than a year. Therefore, these new findings offer additional evidence that intimate partner abuse can affect people’s health long after the trauma has ended.

Ultimately, these findings have important implications for public health and the treatment of asthma. Current asthma treatments target specific types of overinflammation. However, survivors of intimate partner abuse had lower levels of the types of inflammation that medications target. That could be key to understanding why survivors are more likely than other patients to have uncontrolled asthma even with treatment.

Our recent findings suggest that intimate partner abuse may be linked to asthma through other biological mechanisms, such as alternative or nontraditional types of inflammation. More research is needed to identify what drives asthma among survivors so more effective treatments can be developed.

Back pain during pregnancy is often dismissed as a passing discomfort − a nurse explains why it should be taken seriously and treated

Source: The Conversation – USA (3) – By Julie Vignato, Assistant Professor of Nursing, University of Iowa

Serious and even debilitating back pain during pregnancy is extremely common. Jose Luis Pelaez Inc/DigitalVision via Getty Images

About half to three-quarters of expectant mothers experience pain during pregnancy that is largely untreated, contributing to preventable suffering and harm. Many mothers avoid medications and treatments during pregnancy for fear that they may cause harm to their unborn baby. Yet, most are unaware of the harms that untreated pain in pregnancy may cause.

Like many women, I experienced severe pain in pregnancy. As a nurse researcher, I listen to women’s stories and analyze data from across the United States. I share these findings through publications, presentations and the media to raise awareness and reduce the suffering of untreated pregnancy pain.

Not just minor ‘discomfort’

Mothers are often told that the pain that comes with pregnancy is a temporary discomfort that comes with the territory – and ends as soon as the baby is born.

But when pain and discomfort persist to the point that mothers cannot sleep, work and care for their other children, mothers are experiencing pain that needs to be addressed. And for some mothers, the pain does not just eventually fade. Back pain and headaches, for example, can last longer than three months, becoming a chronic condition that affects overall health.

Normal changes that occur during pregnancy often lead to pain. Pregnancy pain normally occurs from hormonal changes that can cause headaches and loosening of pelvic joints. The loosening of joints and the weight of the unborn baby contribute to back pelvic pain. The weight of the developing baby also causes the spine to abnormally curve, a condition called lordosis.

Back and pelvic pain increase in the third trimester of pregnancy when the weight of the baby is at its greatest. This is why it’s incredibly important for doctors and loved ones to believe mothers when they report pain. However, one meta-analysis, meaning an in-depth review of existing research, found that more than 50% of mothers who reported their pain received little to no treatment from their doctors.

Inadequacy of current treatments

Current treatments for pain during pregnancy are highly limited.

Tylenol, though safe – despite the current controversy – treats only mild pain and is ineffective for moderate to severe muscle pain.

Alternative treatments that are also recommended and can be effective, such as heat or cold applications, massage, chiropractic adjustments, exercise and physical therapy, may need to be used in unison and on an ongoing basis. These treatments are not always covered by insurance.

The most effective approach combines several treatments, including exercise that may be provided through physical therapy. Unfortunately, this care may be costly for mothers without adequate insurance, and awareness of these options varies among providers.

The harms of untreated pregnancy pain

My team’s research reveals that when mothers report pain during pregnancy to their health care providers and loved ones, mothers are typically instructed to go home, rest, take Tylenol, go on maternity leave or a combination of these. However, this does not meet the needs of mothers who must work or care for other children. In addition, going on leave early is not an option for many mothers who desire to save their limited maternity leave for after the baby is born.

Mothers will almost always continue to take care of their children or work at the expense of their health if they feel there are no other choices. However, when expectations from their work, family or themselves are not met, mothers may feel guilty about not being a good enough mother or employee. This cycle can contribute to mental health challenges.

When pain is left untreated, mothers may feel minimized, unheard and overwhelmed. In turn, they can start to feel helpless and hopeless, which are symptoms of depression. My colleagues and I found that approximately 44% of women with severe pain report moderate to severe depressive symptoms during the third trimester of pregnancy.

Untreated depression can also lead to suicide, which is responsible for 5% to 20% of maternal deaths in the U.S.

Equally important, opioid or narcotic pain relievers may be prescribed for pregnant mothers experiencing severe pain. Yet, 1 in 5 women with pain report misusing these prescribed medications during pregnancy to relieve pain. In turn, this increases the risk of newborns experiencing withdrawal from these medications after birth, causing significant suffering. Sadly, neonatal opioid withdrawal syndrome is becoming more common, costing the country over US$462 million annually.

With suicide and drug overdoses now the leading causes of death in the year after childbirth, effective pain management in pregnancy is urgently needed.

Being assertive about pregnancy pain

Managing pregnancy pain starts with open communication between the mother and their health care provider. Our studies reveal that by gently adjusting expectations, sharing how they feel and asking about available treatments, mothers can take an active role in ensuring their pain is understood and addressed.

Pregnant mothers are strong, but it’s natural to slow down. Pregnancy is a time to listen to your body and adjust expectations. I believe that balance matters. If pain prevents you from lifting your toddler, that’s OK. What your child will remember the most are the moments you snuggled with them on the couch.

My team’s studies reveal that talking to loved ones about pain may be a challenge. So choose a calm, quiet time without distractions – when everyone can listen and respond thoughtfully. Be open about how you feel and clear about the help you need. Using “I” statements such as “I feel …” also helps. Allow for questions.

Share reliable articles or invite loved ones to a medical appointment so they can better understand what you are experiencing. If someone dismisses your pain, reach out to others who are more supportive.

It is also important to start the conversation with your doctor, midwife or nurse practitioner. Before your appointment, jot down your main concerns and any questions you would like to ask.

Be honest about your pain, especially if it is preventing you from sleeping or doing your usual activities. Tell your provider whether the pain is constant or comes and goes, and describe what it feels like – achy, throbbing, sharp or dull. Even mild ongoing pain that disrupts rest or daily life is important.

Share what you’ve already tried and how well those treatments have worked. If your pain is not improving, reach out to discuss other options, such as prescription medications or a referral to physical therapy. Sometimes, it takes more than one conversation to find relief.

If your pain continues, ask about consulting with a specialist or another health care provider for a different perspective. If your pain improves with treatment but your insurance requests you stop, ask your provider to help appeal the decision. Ongoing treatment throughout pregnancy may be necessary to control your pain.

Relief is possible when pain is taken seriously, not dismissed as an unavoidable harm of pregnancy.

The Jew in King Shaka’s court: How a 19th-century castaway shaped a Zulu leader’s legacy

Source: The Conversation – USA (3) – By Adam L. Rovner, Director of the Center for Judaic Studies, University of Denver

Gales tore at the Mary’s sails, and surf crashed across the brig’s deck. Seventeen-year-old Nathaniel Isaacs tied himself to a railing to avoid being washed overboard. The Mary’s rudder soon splintered against a rocky bar at the entrance to Natal Bay – what is now Durban, South Africa. Helpless to maneuver, the ship took on water.

It was Oct. 1, 1825. Isaacs, a Jewish apprentice merchant from England, loosed the rope around his waist and jumped for his life, landing on the edge of the Zulu kingdom.

Though his name is virtually unknown today, Isaacs went on to play a pivotal role during the period of first contact between the Zulu and Europeans. His widely reviewed 1836 memoir, “Travels and Adventures in Eastern Africa,” offers an eyewitness account of the Zulu under the indomitable King Shaka, who reigned from the 1810s to 1828. As I learned while researching my 2025 book, “The Jew Who Would Be King,” Isaacs’ writing shaped the mythology around Shaka Zulu, who endures as a Black nationalist icon.

A South African airport is named after Shaka, and the country’s Heritage Day is held on the supposed date of his assassination. But his fame stretches far beyond.

He has been name-checked in hip-hop culture for decades, including by Nicki Minaj and Travis Scott. An enormous sculpture of Shaka marks the now defunct Shaka Zulu nightclub in London, while a bar keeps his name alive in Germany. In the U.S. he lends his name to a streetwear brand, and his fearsome scowl adorns stickers and T-shirts. Recently, a South African miniseries, well-received by scholars, has revived his legacy for a new generation.

‘Lost tribe’ speculation

The fact that an Anglo-Jewish castaway helped forge Shaka’s legend seems surprising today. But in 19th-century England, this unlikely pairing would have made perfect sense.

The prevailing pseudoscience of the time concluded that Jews and Africans shared the same imagined racial essence. Given this fanciful equivalency, British voyagers and missionaries “found” the lost tribes of Israel wherever they looked, whether among the Native populations of North America or Indigenous peoples in Africa.

Isaacs himself suspected the Zulu of having a Jewish origin. In one letter, he described Shaka as possessing facial features that revealed “a Hebrew expression” – wishful thinking that echoed a wider cultural belief.

In other ways, Isaacs was a sober observer, describing Zulu politics, military tactics, family dynamics and rituals. In his memoir he describes Shaka as a powerful empire-builder who shrewdly assimilated conquered tribes and territory into his realm – large portions of what is today eastern South Africa. Oral histories confirm Isaacs’ assessment, with one Zulu witness noting that Shaka “established colonies like the Europeans.” According to another, the Zulu king welcomed Isaacs and “deliberately made friends of the first settlers” who washed up on Zulu lands.

‘Savage’ stereotypes

Isaacs made the most of Shaka’s hospitality – a sharp contrast to the king’s supposed ferocity, which remains a core part of Shaka’s legend.

On his first visit to the “sanguinary chief,” as Isaacs referred to Shaka, he witnessed the king order the seizure of three disobedient subjects. Their necks were broken and they were dragged away to the bush to be impaled, their bowels punctured. Some scholars believe Isaacs sensationalized Shaka’s violence – such as historian Carolyn Hamilton – yet assert that “Travels and Adventures” remains one of the most valuable sources of Shakan history.

Zulu witnesses also emphasized Shaka’s brutality. According to Magidigidi, who was born during Shaka’s reign and served as a mat-bearer, a kind of military page, the king was known as “the wrong-doer who knows no law.”

Europeans commonly exaggerated the cruelties of African leaders, often portraying them as “savages.” To many colonial writers of the time, reason, science, private property and commerce marked “civilization.” Irrationality, superstition, communal living and barter marked “savagery” – though they believed cultures and individuals could progress from one state to the other.

Isaacs detailed Shaka’s “savage propensities,” indicating that he saw his own culture as superior. Chauvinism can, of course, easily transmute into coarse racism. Yet he also treated the Zulu with admiration, praising men and women for their athleticism, agility, bravery, cleanliness, discipline and hospitality.

Racial pseudoscience

Perhaps Isaacs’ praise of the Zulu derived in part from his Jewish identity; he too would have been dismissed as “savage” in England. As historian Derek Penslar writes, Jews were imagined as “crass and venal, lacking honor and virtue, in thrall to a slave religion or unrestrained passion.”

The presumed inferiority of Jews meant that European Christians often considered them “black,” both metaphorically and physically. Physician and early anthropologist James Cowles Prichard wrote that depending on the climate in which Jews lived they could become swarthy, even black. One implication of Prichard’s belief was that environment and culture shaped race, which was thought to be a more mutable category of identity than people often consider it today.

Cultural historian Sander Gilman summarized this curious history: “In the eyes of the non-Jew who defined them in Western society the Jews became the blacks.”

H. Rider Haggard, the English novelist and former civil servant in South Africa, played on this imagined connection between Jews and Black Africans. “King Solomon’s Mines,” published in 1885, depicts a breakaway Zulu enclave as the source for the biblical King’s riches.

Isaacs’ “Travels and Adventures” avoids such wild speculation, but he does note King Shaka’s fascination with Judeo-Christian theology. One night, Shaka invited him to speak about faith. “The religion of our nation taught us to believe in a Supreme Being,” Isaacs explained, a god who “created all things, and was the giver of light and life.” Shaka “seemed as if struck with profound astonishment” when Isaacs regaled him with the biblical account of creation.

Kingly legacy

Isaacs was equally spellbound by the Zulu. He hunted elephants for ivory, established a homestead and distinguished himself in battle. Shaka rewarded him with a praise name – a great honor – and the title of “induna,” a chieftain or headman.

Isaacs, in turn, lauded Shaka’s highly disciplined and militarized kingdom. Following his lead, Haggard lavished praise on Shaka’s genius, noting that the Zulu military was among “the most wonderful that the world has seen.” More recently, Marvel’s “Black Panther” features a former king of an isolationist African state jealously guarding its military supremacy. The king’s name? T’Chaka.

African writers have likewise shrouded Shaka in legends of martial prowess. Zulu scholar, author and exiled African National Congress activist Mazisi Kunene’s epic “Emperor Shaka the Great,” published in 1979, hews to Isaacs’ depiction of a fierce yet noble Shaka.

Isaacs even appears in Kunene’s work, which advanced Zulu nationalism in the face of apartheid. The titular King Shaka declares that Isaacs “possessed true humanity,” and one of Shaka’s advisers counsels that Isaacs should be considered a Zulu and no longer be treated as “a foreigner or white man.”

Two hundred years after Isaacs’ shipwreck, much of Shaka’s legend can still be traced back to the travels and adventures of a teenage Jewish Zulu chief.

Trump’s ability to counter Netanyahu’s spoiler tactics in public may have been key to advancing a ceasefire in Gaza

After two years of devastating war between Israel and the Palestinian Hamas forces in the Gaza Strip, President Donald Trump declared an end to the war on Oct. 14, 2025. The peace plan includes a Hamas commitment to return all hostages and a withdrawal of Israeli forces.

In late October, both sides said they remained committed to peace, despite Israeli retaliation for the death of an Israeli soldier that killed 104 people, and despite the fact that the remains of 11 deceased hostages remain in Gaza.

Those setbacks aside, the new peace push is the most serious attempt so far to end the escalation of conflict that followed the Oct. 7, 2023, attack by Palestinian militants on Israelis.

But what are the circumstances and actions that helped Trump advance such an agreement, the likes of which eluded former President Joe Biden? And what enabled Trump, working with a few close advisers and with mediators like Qatar and Egypt, to overcome the reluctance of Israel and Hamas?

The answer may have much to do with how Trump countered a phenomenon that political scientists call “spoiling.”

“Spoiling” in peace negotiations is defined by political scientist Stephen Stedman as actions employed by “leaders and parties who believe that peace emerging from negotiations threatens their power, worldview, and interests, and use violence to undermine attempts to achieve it.”

In regard to the Middle East, critics have long accused Israeli Prime Minister Benjamin Netanyahu of playing this spoiler card throughout the war.

Netanyahu was seen by many observers to be not interested in reaching a peace agreement because of risks to the political survival of his governing coalition. And it’s evident in attempts to postpone the investigation of the colossal failure of Israel to defend its citizens on Oct. 7, 2023.

For two years, Netanyahu engaged in this kind of spoiling by, for example, staging high-level assassinations of Hamas leaders at a timing detrimental for any negotiation’s success.

Yet, Netanyahu also employed a more sophisticated method of spoiling, one that political science scholar Ehud Eiran and I are exploring in our research.

We argue that leaders can spoil negotiations not just by resorting to violent means, or by posing hard-line positions within the negotiation room. Additionally, spoilers can work in broad daylight and make the diplomacy less likely to succeed through a careful use of rhetoric and media. This decreases their own constituencies’ and the enemy’s likelihood of accepting This decreases the likelihood of their own constituencies or the enemy accepting a compromise. It’s what we call “public spoiling.”

Spoiling in broad daylight

Netanyahu used these public spoiling tactics again and again during ceasefire negotiations.

In early May 2024, for example, when ceasefire negotiations were getting into high gear and indications mounted that Hamas may accept the deal on the table, a statement from Netanyahu attributed to “a senior diplomatic source” – known in the Israeli media to mean the prime minister himself – stated that “the IDF will enter Rafah and destroy the Hamas battalions remaining there, whether there is a temporary truce for releasing the hostages or not,” referring to the Israel Defense Forces.

Such declarations signaled to Hamas that Israel did not intend to keep its side of a deal. And it led the Palestinian militant organization to harden its position and further insist on a formal end of the war before all hostages were released.

In September 2024, Netanyahu used the Israeli military in another spoiler tactic after pressure mounted on him to yield to protesters’ calls for a ceasefire

After Hamas operatives murdered six Israeli hostages as soldiers approached their hiding place, the Israeli public erupted in protests against its government, blaming it for sending soldiers instead of negotiating. High-level officers in the prime minister’s office then stole a document from Israeli intelligence, allegedly written by Hamas leader Yahya Sinwar, forged some of it, and leaked it to the German newspaper Bild.

Netanyahu then cited the document in a speech, claiming Sinwar designed his policy to use public pressure on Netanyahu. In short, he used this false publication, leaked allegedly by his own people, to suggest that the protesters were doing Hamas’ bidding. The protests subsequently decreased dramatically, and the pressure on Netanyahu to compromise subsided.

This pattern continued into the Trump administration.

‘No daylight’

U.S. decision-makers, from the president to negotiators in the Biden and Trump administrations, were no doubt aware of these practices. So why did they allow them to continue?

The answer is complicated. What has become clear, I believe, is that at the heart of the problem stands a single phrase: “no daylight.” It’s an oft-cited position of U.S. politicians to mean that, publicly at least, Israel and the United States act as if they are in complete agreement or alignment, with no policy differences between them.

Though a longtime ally of Israel, the U.S. used to be more forceful with Israel when the latter was deemed by Washington to have crossed the line or threatened important American interests in the region. That was evident when the U.S. imposed a ceasefire in the 1973 Arab-Israeli War despite Israeli opposition. It was also clear when the U.S. prevented an Israeli response to missiles that Iraq launched at it during the Gulf War in 1991.

But in the past few decades, a perception has taken hold in U.S. foreign policy circles that pressure on Israel’s government should only be done in private and that it should never include strong public rebuke.

Thus, even when, in June 2024, the Biden administration knew full well that Netanyahu was thwarting efforts to reach a ceasefire, former Secretary of State Antony Blinken came out with a statement blaming Hamas. And when Netanyahu breached a ceasefire in March 2025 and ordered the military to return to fighting, the Trump administration blamed Hamas.

Netanyahu, with his knowledge of U.S. politics, was well aware that Washington would be unlikely to publicly blame Israel. And he took full advantage of this fact to promote his spoiling of the ceasefire negotiations in broad daylight.

No choice but to sign

So what changed in October 2025 that allowed Trump to overcome Netanyahu’s actions as a spoiler and secure a ceasefire?

In short, Trump simply decided to play the same game. He publicly announced that the deal existed and left Netanyahu no choice but to sign it to preserve the perception that there is “no daylight” between Israel and the U.S. As a former Netanyahu aid suggested, “Trump is unpredictable and will not fall in line with the Israeli position.”

Trump’s announcement of the deal, before many of the details were agreed upon, enabled the ceasefire agreement, Israel’s partial withdrawal from Gaza and Hamas’ release of the Israeli hostages.

The road to an actual end of the war, not to mention Trump’s lofty declarations of a historic peace, is still in the far distance. But the ceasefire, if it holds, is a critical step, in my view, to end this terrible chapter of the Israeli-Palestinian conflict.

Les animaux réagissent de différentes manières lorsqu’ils sont blessés.
Mais jusqu’ici, on avait rarement la preuve qu’ils utilisaient des substances actives pour soigner leurs plaies. Une étude récente sur un orang-outan soignant une blessure à l’aide d’une plante médicinale offre une piste prometteuse.

On sait que les chimpanzés lèchent leurs blessures. Ils appliquent parfois des feuilles dessus. Mais ces comportements restent encore mal compris. On ignore à quelle fréquence ils le font, si c’est fait délibérément, ou jusqu’où va leur ingéniosité face à une blessure.

De récentes observations sur le terrain en Ouganda, en Afrique de l’Est, révèlent désormais des informations intrigantes sur la manière dont ces animaux font face à leurs blessures.

En tant que primatologue, les capacités cognitives et la vie sociale des chimpanzés me passionnent. Leur comportement face à la maladie peut nous renseigner sur les les origines évolutives des soins et de l’empathie chez les humains. Les chimpanzés sont parmi nos plus proches parents. En les comprenant, nous en apprenons beaucoup sur nous-mêmes.

Dans le cadre de nos recherches menées dans le parc national de Kibale, en Ouganda, nous avons observé, à cinq reprises, des chimpanzés appliquer des insectes sur leurs propres plaies ouvertes, et dans un cas sur celles d’un autre individu.

Des comportements tels que l’application d’insectes montrent que les chimpanzés ne sont pas passifs lorsqu’ils sont blessés. Ils expérimentent leur environnement, parfois seuls et parfois avec d’autres. Même s’il ne faut pas conclure trop rapidement qu’il s’agit de « médecine », cela montre qu’ils sont capables de réagir à leurs blessures de manière inventive et parfois de manière solidaire.

Chaque nouvelle découverte nous en apprend un peu plus sur les chimpanzés. Elle nous donne un aperçu des racines communes de nos propres réflexes face à la blessure et à l’envie de soigner.

Attrapez d’abord votre insecte

Nous avons observé l’application d’insectes par hasard alors que nous observions et enregistrions leur comportement dans la forêt, mais nous avons accordé une attention particulière aux chimpanzés présentant des plaies ouvertes.

Application d’insectes par Damien, un chimpanzé subadulte.

Dans tous les cas observés, leurs gestes semblaient délibérés. Le chimpanzé attrapait un insecte volant non identifié, l’immobilisait entre ses lèvres ou ses doigts, et le pressait directement sur une plaie ouverte. Le même insecte était parfois réappliqué plusieurs fois, parfois après avoir été brièvement tenu dans la bouche, avant d’être jeté. D’autres chimpanzés observaient parfois le processus de près, apparemment avec curiosité.

La plupart du temps, le chimpanzé soignait sa propre blessure. Mais dans un cas rare, une jeune femelle a appliqué un insecte sur la plaie de son frère. Une étude a déjà montré que dans cette même communauté, les chimpanzés tamponnent les plaies de membres non-apparentés avec des feuilles. On peut se demander s’ils feraient de même avec des insectes au-delà des membres de la famille.

Les actes de soins, qu’ils soient destinés à la famille ou à d’autres personnes, peuvent révéler les fondements précoces de l’empathie et de la solidarité.

Cette séquence d’actions ressemble beaucoup à ce qu’on observe chez les chimpanzés du Gabon, en Afrique centrale. Cette similitude suggère que l’application d’insectes pourrait représenter un comportement plus répandu chez les chimpanzés qu’on ne le pensait auparavant.

Les découvertes faites dans le parc national de Kibale élargissent notre vision de la façon dont les chimpanzés réagissent aux blessures. Plutôt que de laisser les blessures sans soins, ils agissent parfois de manière délibérée et ciblée.

Les chimpanzés pratiquent-ils les premiers secours ?

La question qui se pose naturellement est de savoir à quoi sert ce comportement. Nous savons que les chimpanzés utilisent délibérément des plantes pour améliorer leur santé : avaler des feuilles rugueuses qui aident à expulser les parasites intestinaux ou mâcher des pousses amères qui auraient des effets antiparasitaires.

Les insectes, cependant, sont un cas à part. Il n’a pas encore été démontré que le fait d’appliquer des insectes sur des blessures accélère la guérison ou réduit les infections. De nombreux insectes produisent des substances antimicrobiennes ou anti-inflammatoires, ce qui rend cette possibilité envisageable, mais des tests scientifiques sont encore nécessaires.

Pour l’instant, nous pouvons affirmer que ce comportement semble ciblé, systématique et délibéré. Le cas unique d’un insecte appliqué sur un autre individu est particulièrement intrigant. Les chimpanzés sont des animaux très sociables, mais l’aide active est relativement rare. Outre les comportements bien connus tels que le toilettage, le partage de nourriture et l’aide apportée lors de combats, l’application d’un insecte sur la blessure d’un frère ou d’une sœur suggère une autre forme de soins, qui va au-delà du simple maintien des relations et pourrait améliorer l’état physique de l’autre.

De grandes questions

Ce comportement soulève d’importantes questions. Si l’application d’insectes s’avère avoir des vertus médicinales, cela pourrait expliquer pourquoi les chimpanzés le font. Ce qui soulève à son tour la question de l’origine de ce comportement : les chimpanzés l’ont-ils appris en observant les autres, ou l’ont-ils découvert de manière plus spontanée ? De là découle la question de la sélectivité : choisissent-ils des insectes volants particuliers ? Et si oui, les autres membres du groupe apprennent-ils à sélectionner les mêmes ?

Dans la médecine traditionnelle humaine (entomothérapie), les insectes volants tels que les abeilles mellifères et les mouches bleues sont appréciés pour leurs effets antimicrobiens ou anti-inflammatoires. Il reste à déterminer si les insectes appliqués par les chimpanzés offrent des bienfaits similaires.

Enfin, si les chimpanzés appliquent effectivement des insectes aux vertus curatives, et s’ils le font parfois sur les plaies d’autrui, cela pourrait être considéré comme une forme d’aide active, voire de comportement prosocial (ce terme est utilisé pour décrire les comportements qui profitent à d’autres plutôt qu’à l’individu qui les adopte).

Observer ces chimpanzés du parc national de Kibale attraper un insecte volant, l’immobiliser et le presser délicatement sur une blessure ouverte rappelle combien leurs capacités restent encore à explorer. Ce comportement s’ajoute à une série d’observations montrant que les origines des comportements de soins et de guérison remontent à une époque beaucoup plus lointaine dans l’évolution.

Si l’application d’insectes s’avère avoir des vertus médicinales, cela renforce l’importance de la protection des chimpanzés et de leurs habitats. À leur tour, ces habitats protègent les insectes qui peuvent contribuer au bien-être des chimpanzés.

Higher education: why women in France are less likely to pursue science than men

Source: The Conversation – France – By Anne Boring, Associate professor, Erasmus University Rotterdam

Girls in France are much less inclined than boys to pursue scientific fields of study, and this is partly due to persistent gender stereotypes. But other factors also come into play. These explanations are based on a survey by the Chair for Women’s Employment and Entrepreneurship at Sciences Po.


How can we attract more women in France to higher education in science and technology? For several years, public authorities have been supporting initiatives aimed at promoting gender diversity in these fields of study, the most recent being the “Girls and Maths” action plan, launched by the ministry of national education, higher education, and research in May 2025.

There are two main reasons behind these initiatives. On the one hand, the aim is to reduce gender inequalities in the labour market, particularly the pay gap. On the other hand, the objective is to support economic growth in promising fields by training more people who can contribute to innovation in strategic sectors of activity.

Different choices

The differences in orientation between women and men remain very marked at the start of higher education. This is evident from the choices made by high school seniors on Parcoursup, the French platform for accessing post-baccalaureate programmes, as can be seen in the following graph based on data made available on Datagouv. It represents the number of applications for the most popular courses of study (more than 4,000 applications).

The x-axis shows female candidates, and the y-axis shows male candidates. The symbols at right, from top to bottom, represent science and technology; STAPS; health; human and social sciences, literature, languages, arts; economics, management, commerce.

The points above the diagonal represent programmes with a predominance of male applicants, while those below represent programmes with a predominance of female applicants. Men account for approximately 70% of applicants to science and technology programmes, including STAPS (science and technology of physical education and sports).

The main exceptions concern courses in life and earth sciences, for which there are more female applicants. Programmes in economics, management, and business (in blue) tend to be more mixed. Finally, programmes in health, humanities, social sciences, literature, languages, and arts (in purple) are mainly favored by women, who account for around 75% of applicants.

Certain factors that may explain these differences in study choices, in particular the role of gender stereotypes, differences in academic performance in science subjects, and self-confidence, have already been analysed.

Passion as a determining factor

In order to better understand the current reasons for the differences between women and men in higher education choices, the Chair for Women’s Employment and Entrepreneurship at Sciences Po conducted a survey in partnership with Ipsos in February 2025 among a representative sample of the student population in France, with a total of 1,500 responses. The results of this survey were published by the Observatory of Well-Being of the Centre for Economic Research and its Applications (Cepremap).

One of the striking findings of the survey concerns the differences between women and men in the importance they attach to passion as a determining factor in their higher education choices.

Significantly more female students choose courses related to their passions, and they seem to do so fully aware that these choices may penalise them later on in the job market. In fact, 67% of women (compared to 58% of men) say they “prefer to study a subject they are passionate about, even if it does not guarantee a well-paid job”, while 33% of women (compared to 42% of men) say they “prefer to get a well-paid job, even if it doesn’t guarantee that they will study a subject they are passionate about”.

Women who prioritise passion are more likely to enrol in arts and humanities programmes, while those who prefer a well-paid job are more likely to enrol in economics, business, and commerce programmes, or in science and technology programmes.

The role of parents

Furthermore, the survey results highlight the fact that parents are more influential in determining their sons’ educational choices than their daughters’. In fact, female students receive more support from their parents, regardless of their chosen field of study, while male students are less likely to receive their parents’ approval, particularly for fields of study that lead to less lucrative careers in the job market (eg humanities, social sciences or arts) or that have become feminised (eg law or health).

Paradoxically, the lack of parental influence on girls’ choices may explain why they are more likely to follow their passion, finding themselves more constrained in the job market later on.

The results also show that preferences developed for different subjects in secondary school account for more than half of the differences between women and men in their higher education choices.

Women appear to have more diverse tastes, with a preference for mathematics accounting for only a small part (around 10%) of the difference in study choices. This partly explains why women tend to shy away from science and technology courses of study, which may be perceived as requiring them to give up other subjects they enjoy. More men than women enjoyed only science subjects in secondary school (29% of male students compared to 14% of female students).

Multidisciplinary programmes and role models

If the French economy needs more women with degrees in science and technology, how can we attract them to these fields? The main challenge lies in conveying a passion for science and technology to women.

This can be achieved through role models, such as high-achieving people who share their enthusiasm for their discipline before students make crucial choices. This can also involve the development of multidisciplinary courses that combine science, social sciences, and humanities, so as to offer young women (and young men) with varied interests the opportunity to pursue scientific studies without giving up other fields.

Finally, science programmes can adapt their educational offerings to make teaching more attractive to female students. By highlighting how science and technology can contribute to the common good and address the challenges of contemporary societies, a reformulation of course titles can, for example, highlight issues that are important to them.

4 urgent lessons for Jamaica’s hurricane recovery from Puerto Rico’s struggles – and how the Jamaican diaspora could help after Melissa

Across Jamaica, streets are littered with torn-off roofs, splintered wood and other debris left in the wake of Hurricane Melissa. Downed power lines have left communities in the dark, and many flooded and wind-damaged homes are unlivable.

Recovering from the devastation of one of the Atlantic’s most powerful storms, which struck on Oct. 28, 2025, will take months and likely years in some areas. That work is made much harder by the isolation of being an island.

As a researcher who has extensively studied disaster recovery in Puerto Rico after Hurricane María in 2017, I know that the decisions Jamaica makes in the days and weeks following the disaster will shape its recovery for years to come. Puerto Rico’s mistakes following Maria hold some important lessons.

Why island recovery is different

Islands face obstacles that most mainland communities don’t experience. Geographic isolation compounds every problem in ways that make both the emergency response and the long-term recovery fundamentally harder.

Communities can easily be cut off by damaged roads, particularly in rugged areas like Jamaica’s Blue Mountains. Every damaged port facility, every closed airport, every blocked road multiplies isolation in both the short and long term.

As Puerto Rico saw after Hurricane Maria, in the early days after a disaster, basic emergency supplies like tarps, batteries, fresh food and water and generators can become scarce.

Weeks and months later, reconstruction materials can still take a long time to arrive, extending the recovery time far beyond what most mainland communities would experience. This isn’t just a price-gouging ploy; it’s the reality of island supply chains and shipping infrastructure under stress. Isolation, limited port capacity and dependence on imports create unique vulnerabilities that slow disaster recovery, as research on Hurricane Maria’s impact on Puerto Rico has shown.

Local organizations: From response to recovery

One of the most important lessons I saw in Puerto Rico is that local nonprofits and community organizations are essential first responders in the emergency phase and then transition into recovery leaders.

These organizations know their communities intimately: who is elderly and homebound, which neighborhoods will have the greatest need, and how to navigate local conditions.

Right now, Jamaican churches, community groups and local organizations are in emergency response mode — checking on residents, distributing water and providing shelter. For example, the Jamaica Council of Churches, which has extensive disaster response experience, has started to coordinate relief efforts though its community networks.

Over the long term, my research shows that local organizations are crucial for helping families recover. They help to navigate insurance claims, organize rebuilding efforts, provide mental health support, and advocate for community needs in recovery planning, among many roles.

However, many disaster recovery funding sources favor larger, international nonprofits over local groups, even for distribution once supplies have arrived. In Puerto Rico after Hurricane María, only 10% of the nearly US$5 billion in federal contracts went to Puerto Rico-based groups, while 90% flowed to mainland contractors.

Jamaica will face similar dynamics as international funding arrives from sources such as the World Bank and Inter-American Development Bank. Ensuring the recovery funding goes through established Jamaican organizations can help the recovery.

The diaspora: Urgent help, long-term support

When institutional systems such as the Federal Emergency Management Agency and the government of Puerto Rico could not offer aid fast enough after Hurricane Maria, diaspora communities became crucial lifelines. Puerto Ricans in Chicago, New York and Florida organized relief efforts, raised funds and shipped supplies within days.

Months later, Puerto Ricans living on the U.S. mainland continued providing financial support. They hosted displaced family members and advocated for federal aid. As my co-author Maura I. Toro-Morn and I document in our book “Puerto Ricans in Illinois,” diaspora communities that mobilized statewide in the aftermath of Hurricane Maria demonstrated how Puerto Ricans supported the island during crisis.

The Jamaican diaspora in London, Toronto, New York and Miami represents a massive potential resource for both immediate relief and long-term recovery.

In the hours after Melissa made landfall, these communities were already trying to reach family members and organize help. In Florida, Jamaican American student associations at several universities set up a GoFundMe page for relief efforts in Jamaica. In Connecticut, Caribbean social groups were gathering their communities to send support.

Jamaica’s government has multiple diaspora engagement platforms, such as JA Diaspora Engage, the Global Jamaica Diaspora Council and JAMPRO. But these primarily focus on economic development and investment rather than disaster response coordination. In contrast, Haiti established the Haitian Diaspora Emergency Response Unit in 2010 specifically for disaster coordination. After the 2021 earthquake, it coordinated relief efforts across more than 200 organizations, raising $1.5 million within weeks.

Jamaica could adapt its existing diaspora infrastructure to include an emergency response component. It could provide regular updates on community needs during disasters, verify trusted local partners for aid distribution, and facilitate logistics for shipping supplies over the years of recovery.

The out-migration risk: When emergencies becomes permanent

Perhaps the most devastating long-term impact of Hurricane María was massive population loss — a recovery failure that began with emergency response decisions.

Of Puerto Ricans who applied for federal assistance, approximately 50% had new addresses on the U.S. mainland. Their displacement that began as a temporary evacuation became permanent when Puerto Rico couldn’t restore viable living conditions quickly enough.

Without housing, employment or basic services for months, families had little choice but to leave. About a quarter of Puerto Rico’s schools were closed by the storm damage. I saw similar patterns in Maui, Hawaii, as it recovered from devastating wildfires in 2023. Limited lodging and high costs made it impossible for many displaced residents to stay.

Researchers estimated that of the nearly 400,000 people who left Puerto Rico in 2017 and 2018 after María, maybe 50,000 had returned by 2019.

Jamaica faces similar risks. The out-migration crisis doesn’t happen all at once – it’s a slow bleed that accelerates as emergency response transitions into prolonged recovery.

The time to prevent that pressure to leave is now. The government can help by communicating realistic timelines for service restoration and prioritizing school reopening. Every week increases the risk that temporary displacement becomes permanent emigration.

Building back better: Recovery, not just response

Disasters create opportunities to build back better, but that requires thinking about the future rather than simply recreating what existed before.

Jamaica can prioritize speed in emergency response by rebuilding the old system, or it can invest in a recovery that also builds resilience for the future. Climate change is fueling more intense and destructive hurricanes, leaving Caribbean islands at growing risk of damage.

Hurricane Maria revealed serious infrastructure vulnerabilities as the aging power grid collapsed under Category 4 winds. Puerto Rico could have rebuilt with more modern, resilient infrastructure. However, RAND Corporation research found that reconstruction largely restored the old, vulnerable centralized power system, rather than transforming it with distributed renewable energy, hardened transmission lines and microgrids that could withstand future storms.

Water systems, roads, schools and hospitals could also be rebuilt to better withstand storms and with redundancy – such as backup power sources and distributed water systems – to help the island recover faster in future hurricanes.

These improvements are expensive, and Jamaica will need international donors to help fund the recovery, not just the immediate emergency response.

The decisions made today will echo for years. Jamaica’s recovery doesn’t have to repeat Puerto Rico’s mistakes.

Cómo sobreviven las catrinas y los altares de muertos a Halloween y TikTok sin perder su identidad

Una catrina en el desfile del Día de Muertos en Ciudad de México. Eve Orea/Shutterstock

El Día de Muertos es una tradición que ha atravesado décadas de transformación y representa, actualmente, la expresión cultural más emblemática de México. Sin embargo, estos cambios se han visto acelerados en los últimos años debido a la presencia de esta celebración en redes sociales, donde se proyecta como un espectáculo visual.

En TikTok, Instagram y YouTube, los altares y las catrinas son representados con disfraces de Halloween y retos virales. Una mezcla que combina lo sagrado y lo festivo con lo viral.

El espectáculo patrimonial

La inclusión del Día de Muertos en la lista de Patrimonio Inmaterial de la Humanidad de la UNESCO en 2008 lo ha convertido en un símbolo patrimonial de lo mexicano, que se ha visto impulsado por políticas culturales y turísticas.

El desfile de la Ciudad de México, inspirado en la película de James Bond Spectre (2015), trasladó la celebración del espacio doméstico al espacio público. A ello se suman ferias, festivales y rutas turísticas que promocionan la “experiencia” del Día de Muertos como producto cultural.

En este contexto, las redes sociales amplifican la puesta en escena. En TikTok, los vídeos muestran los preparativos de ofrendas, los concursos de catrinas o los maquillajes rituales. Este desplazamiento de elementos vernáculos hacia medios digitales refleja cómo la tradición se transforma en espectáculo, pero mantiene la emoción colectiva de recordar a los muertos. Lo que antes era un acto íntimo hoy se convierte en contenido que se comparte, al que se da “me gusta”, pero que aún así afirma la identidad y el sentido de pertenencia.

De la tradición indígena a la cultura pop

El Día de Muertos es el resultado de mezclar prácticas mesoamericanas de culto a los ancestros con las conmemoraciones ibéricas y católicas del Día de Todos los Santos. Ese sincretismo etnoterritorial, como lo define la antropología, dio lugar a una celebración profundamente identitaria.

En la actualidad, sin embargo, se vive otra ola de sincretismo. El encuentro entre la herencia indígena y la cultura pop global se fusionan. En TikTok abundan vídeos donde las ofrendas tradicionales incorporan calabazas, luces LED o disfraces inspirados en películas como Coco (Pixar/Disney, 2017).

Este fenómeno puede leerse desde la perspectiva de las “culturas híbridas”, que Néstor García Canclini instauró en su obra del mismo título. En línea con este concepto acuñado por el antropólogo de origen argentino, pero afincado en México, este tipo de expresiones culturales no consisten en una simple imitación de lo extranjero, sino en una reapropiación, donde los símbolos globales son reinterpretados. Así, el altar con veladoras y papel picado coexiste con filtros digitales, lo que demuestra que las identidades culturales no desaparecen, sino que se transforman.

Globalización mediática y consumo simbólico

El poder de los medios y del mercado también ha influido en la resignificación actual. Un ejemplo claro es la campaña de la cerveza Victoria, que desde hace años crea cortometrajes, productos y piezas publicitarias inspiradas en los mitos prehispánicos del inframundo.

En uno de los vídeos virales recientes, la marca cervecera mezcla el relato mítico de Mictlán (el inframundo de la mitología mexica y nahua) con la historia moderna de la cerveza, produciendo un discurso que une lo ancestral y lo comercial. Es decir, la identidad con la modernidad.

Estas estrategias incluyen cervezas con sabor a cempasúchil (la flor tradiconal del Día de Muertos), narrativas de “orgullo mexicano” y colaboraciones con artistas, como el bailarín Isaac Hernández.

Su implantación a través del marketing y la publicidad revela cómo la identidad cultural se convierte en un lenguaje de marca vivencial. No obstante, también evidencia que las empresas recurren a los símbolos, como el Día de Muertos, no solo para vender, sino para reconectar emocionalmente al público con su cultura y con el producto desde el terreno del consumo.

De esta manera, la patrimonialización del Día de Muertos, impulsada por el turismo y las redes sociales, funciona como un espejo de la sociedad, donde se expresa tanto el orgullo identitario como la apropiación comercial de lo sagrado.

De los altares blancos al meximalismo identitario y la tropicalización

Otro debate reciente visible en TikTok es el de los llamados “altares blancos” o “altares minimalistas”. Algunos vídeos muestran cómo las tendencias de diseño contemporáneo, marcadas por el gusto neutro y las estéticas de catálogo, se han trasladado a la tradición del altar. En ellos, las flores de cempasúchil se sustituyen por arreglos blancos, las veladoras de colores por luces frías, y los objetos personales del difunto por elementos decorativos.

Este fenómeno, más allá del gusto estético, plantea una reflexión sobre la identidad. El altar mexicano no responde al principio de “menos es más”, sino a una lógica del meximalismo, donde “más es más”: colores, aromas, texturas y símbolos que cuentan una historia viva. Frente a la homogeneización del diseño global, el altar tradicional actúa como resistencia simbólica, por lo que no se trata de una tendencia decorativa, sino de una forma de reafirmar la historia colectiva y los vínculos afectivos que sostienen la identidad mexicana.

Otros contenidos virales muestran cómo la cultura mexicana se reapropia de su identidad al revivir el Día de Muertos sobre la tradición del Halloween. Las catrinas vuelven a tener protagonismo frente a los zombies o monstruos anglosajones, en un proceso de tropicalización. Una suerte de mezcla festiva, donde lo local se fortalece al dialogar con lo global.

A diferencia de los años ochenta y noventa, cuando Halloween ganaba terreno porque representaba lo moderno y extranjero, hoy el Día de Muertos se vive con orgullo y creatividad.

Sin embargo, vale la pena preguntarse si esta revitalización se sostiene desde lo comunitario o desde el espectáculo. Películas como Coco o Spectre o eventos como el “paseo ciclista de Día de Muertos”, donde se encienden luces y se usan disfraces, pueden ser al mismo tiempo mecanismos de difusión y de superficialización del rito. De esta manera, la frontera entre tradición y el performance se vuelve cada vez más difusa.

Es en esa mezcla de altar y filtro digital, de catrina y lente pop, de mercado y memoria donde se encuentra la expresión contemporánea de una identidad mexicana que dialoga con el mundo sin perder su raíz. Porque, como toda tradición, el Día de Muertos no se conserva: se vive.

Plutôt que de chercher à faire rire à tout prix, mieux vaut adopter la façon de penser des humoristes pour stimuler la créativité, renforcer l’esprit d’équipe et se démarquer sans déraper.


Comment progresser dans sa carrière sans trop s’ennuyer ? Une solution souvent évoquée dans les livres de management, sur LinkedIn
ou dans les manuels de team building, consiste à manier l’humour. Partager des blagues, des remarques sarcastiques, des mèmes ironiques ou des anecdotes spirituelles, dit-on, vous rendra plus sympathique, réduira le stress, renforcera les équipes, stimulera la créativité et pourra même révéler votre potentiel de leader.

Nous sommes professeurs de marketing et de management spécialisés dans l’étude de l’humour et des dynamiques de travail. Nos propres recherches – ainsi qu’un nombre croissant de travaux menés par d’autres chercheurs – montrent qu’il est plus difficile d’être drôle qu’on ne le croit. Les conséquences d’une mauvaise blague sont souvent plus lourdes que les bénéfices d’une bonne. Heureusement, il n’est pas nécessaire de faire hurler de rire son entourage pour que l’humour vous soit utile. Il suffit d’apprendre à penser comme un humoriste.

L’humour, un exercice risqué

La comédie repose sur le fait de tordre et de transgresser les normes – et lorsque ces règles ne sont pas brisées de la bonne manière, cela nuit plus souvent à votre réputation que cela n’aide votre équipe. Nous avons développé la « théorie de la violation bénigne »
pour expliquer ce qui rend une situation drôle – et pourquoi tant de tentatives d’humour tournent mal, notamment au travail. En résumé, le rire naît lorsque quelque chose est à la fois « mal » et « acceptable ».

Les gens rient lorsque les règles sont transgressées sans danger. Si l’un des deux éléments manque, la blague tombe à plat. Quand tout est bénin et qu’il n’y a aucune transgression, on s’ennuie. Quand il n’y a que transgression sans bénignité, on provoque l’indignation.

Il est déjà difficile de faire rire dans la pénombre d’un comedy club. Sous les néons d’un bureau, la ligne devient encore plus mince. Ce qui paraît « mal mais acceptable » à un collègue peut sembler simplement inacceptable à un autre, selon la hiérarchie, la culture, le genre ou même l’humeur du moment.

La série « The Office » excelle dans l’art d’exposer les conséquences d’une transgression ratée.

Une étude publicitaire

Dans nos expériences, lorsque des personnes ordinaires sont invitées à « être drôles », la plupart de leurs tentatives tombent à plat ou franchissent des limites. Lors d’un concours de légendes humoristiques avec des étudiants en école de commerce – décrit dans le livre de Peter McGraw sur l’humour à travers le monde, The Humor Code, les propositions n’étaient pas particulièrement drôles au départ. Pourtant, celles jugées les plus amusantes étaient aussi considérées comme les plus déplacées.

Être drôle sans être offensant est donc essentiel. C’est particulièrement vrai pour les femmes : de nombreuses études montrent qu’elles subissent des réactions plus négatives que les hommes lorsqu’elles adoptent des comportements perçus comme offensants ou transgressifs, tels que l’expression de la colère, l’affirmation de dominance ou même les demandes de négociation.

Risquer de perdre tout respect

Les recherches menées par d’autres spécialistes du comportement des leaders et managers racontent la même histoire. Dans une étude, les managers qui utilisaient l’humour efficacement étaient perçus comme plus compétents et plus sûrs d’eux, ce qui renforçait leur statut. Mais lorsque leurs tentatives échouaient, ils perdaient aussitôt crédibilité et autorité. D’autres chercheurs ont montré qu’un humour raté ne nuisait pas seulement au statut d’un manager, mais réduisait aussi le respect, la confiance et la volonté des employés de solliciter ses conseils.

Même lorsqu’une blague fait mouche, l’humour peut se retourner contre son auteur. Dans une étude, des étudiants en marketing chargés d’écrire des publicités « drôles » ont produit des annonces plus amusantes, mais moins efficaces, que ceux invités à rédiger des textes « créatifs » ou « persuasifs ».

Une autre étude a révélé que les patrons qui plaisantent trop souvent poussent leurs employés à feindre l’amusement, ce qui épuise leur énergie, réduit leur satisfaction et augmente le risque d’épuisement professionnel. Et les risques sont encore plus élevés pour les femmes en raison d’un double standard : lorsqu’elles utilisent l’humour dans une présentation, elles sont souvent jugées moins compétentes et de plus faible statut que les hommes.

En résumé, une bonne blague ne vous vaudra presque jamais une promotion. Mais une mauvaise peut mettre votre poste en danger – même si vous n’êtes pas un animateur de talk-show payé pour faire rire.

Inverser la perspective

Plutôt que d’essayer d’être drôle au travail, nous recommandons de vous concentrer sur ce que nous appelons « penser drôle » – comme le décrit un autre livre de McGraw, “Shtick to Business.

« Les meilleures idées naissent comme des blagues », disait le légendaire publicitaire David Ogilvy. « Essayez de rendre votre manière de penser aussi drôle que possible. » Mais Ogilvy ne conseillait pas aux dirigeants de lancer des blagues en réunion. Il les encourageait à penser comme des humoristes : renverser les attentes, s’appuyer sur leurs réseaux et trouver leur propre registre.

Les humoristes ont souvent pour habitude de vous emmener dans une direction avant de renverser la situation. Le comédien Henny Youngman, maître des répliques percutantes, a ainsi lancé cette célèbre boutade : « Quand j’ai lu les dangers de l’alcool, j’ai arrêté… de lire. »
La version professionnelle de cette approche consiste à remettre en cause une évidence.

Par exemple, la campagne « Don’t Buy This Jacket » de Patagonia, publiée en pleine journée du Black Friday 2011 sous forme de page entière dans le New York Times, a paradoxalement fait grimper les ventes en dénonçant la surconsommation.

Pour appliquer cette méthode, identifiez une idée reçue au sein de votre équipe – par exemple, que l’ajout de nouvelles fonctionnalités améliore toujours un produit, ou que multiplier les réunions favorise une meilleure coordination – et demandez-vous : « Et si c’était l’inverse ? » Vous découvrirez alors des pistes que les séances de brainstorming classiques laissent souvent passer.

Créer un fossé

Quand l’humoriste Bill Burr fait hurler de rire son public, il sait que certaines personnes ne trouveront pas ses blagues drôles – et il ne cherche pas à les convaincre. Nous avons observé que beaucoup des meilleurs comiques ne cherchent pas à plaire à tout le monde. Leur succès repose justement sur le fait de restreindre délibérément leur audience. Et nous constatons que les entreprises qui adoptent la même stratégie bâtissent souvent des marques plus fortes.

Par exemple, lorsque l’office du tourisme du Nebraska a choisi le slogan « Honnêtement, ce n’est pas pour tout le monde » dans une campagne de 2019 visant les visiteurs hors de l’État, le trafic du site web a bondi de 43 %. Certaines personnes aiment le thé chaud, d’autres le thé glacé. Servir du thé tiède ne satisfait personne. De la même manière, on peut réussir en affaires en décidant à qui une idée s’adresse – et à qui elle ne s’adresse pas – puis en adaptant son produit, sa politique ou sa présentation en conséquence.

Coopérer pour innover

Le stand-up peut sembler un exercice solitaire. Pourtant, les humoristes dépendent du retour des autres – les suggestions de leurs pairs et les réactions du public – et peaufinent leurs blagues comme une start-up agile améliore un produit.

Construire des équipes performantes au travail suppose d’écouter avant de parler, de valoriser ses partenaires et de trouver le bon équilibre entre les rôles. Le professeur d’improvisation Billy Merritt décrit trois types d’improvisateurs : les pirates, qui prennent des risques ; les robots, qui bâtissent des structures ; et les ninjas, capables de faire les deux à la fois – oser et organiser.

Une équipe qui conçoit une nouvelle application, par exemple, a besoin des trois : des pirates pour proposer des fonctionnalités audacieuses, des robots pour simplifier l’interface, et des ninjas pour relier le tout. Donner à chacun la possibilité de jouer pleinement son rôle permet de générer des idées plus courageuses, avec moins d’angles morts.

Les dons ne sont pas universels

Dire à quelqu’un « sois drôle » revient à lui dire « sois musical ». Beaucoup d’entre nous savent garder le rythme, mais peu ont le talent nécessaire pour devenir des rock stars.C’est pourquoi nous pensons qu’il est plus judicieux de penser comme un humoriste que d’essayer d’en imiter un.

En renversant les évidences, en coopérant pour innover et en assumant des choix clivants, les professionnels peuvent trouver des solutions originales et se démarquer — sans devenir la risée du bureau.
