When it comes to major U.S. industries, three tends to be the magic number.

Historically, auto manufacturing was long dominated by Chrysler, Ford and General Motors – the so-called “Big Three,” which at one point controlled over 60% of the U.S. auto market. A dominant trio shows up elsewhere, too, in everything from the U.S. defense market – think Lockheed Martin, Boeing and Northrup Grumman – to cellphone service providers (AT&T, T-Mobile and Verizon). The same goes for the U.S. airline industry in which American, Delta and United fly higher than the rest.

The rule of three also applies to what Americans watch; the glory days of television was dominated by three giants: ABC, CBS and NBC.

Now, in the digital age, we are rapidly moving to a “Big Three” dominating streaming services: Netflix, Amazon and Disney.

The latest step in that process is Netflix’s plan to acquire Warner Bros. for US$72 billion. If approved, the move would solidify Netflix as the dominant streaming platform.

When streams converge

Starting life as a mail DVD subscription service, Netflix moved into streaming movies and TV shows in 2007, becoming a first-mover into the sphere.

Being an early adopter as viewing went from cable and legacy to online and streaming gave Netflix an advantages in also developing support technology and using subscriber data to create new content.

The subsequent impact was Netflix became a market leader, with quarterly profits now far exceeding its competitors, which often report losses.

Today, even without the Warner Bros. acquisition, Netflix has a dominant global base of over 300 million subscribers. Amazon Prime comes second with roughly 220 million subscribers, and Disney – which includes both Disney+ and Hulu – is third, with roughly 196 million subscribers. This means that between them, these three companies already control over 60% of the streaming market.

Netflix’s lead would only be reinforced by the proposed deal with Warner Bros., as it would add ownership of Warner subsidiary HBO Max, which is currently the fourth-biggest streamer in the U.S. with a combined 128 million subscribers. While some of them will overlap, Netflix is likely to still gain subscribers and better retain them with a broader selection of content.

Netflix’s move to acquire Warner Bros. also follows prior entertainment industry consolidation, driven by a desire to control content to retain streaming service subscribers.

In 2019, Disney acquired 21st Century Fox for $71.3 billion. Three years later, Amazon acquired Metro-Goldwyn-Mayer for $8.5 billion.

Should the Netflix deal go through, it would continue this trend of streaming consolidation. It would also leave a clear gap at the top between the emerging Big Three and other services, such as Paramount+ with 79 million subscribers and Apple TV+, which has around 45 million. Paramount+ was also a rival bidder for Warner Bros., and while it is protesting Netflix’s deal for Warner Bros., it likely will need to pursue other options to remain relevant in streaming.

Why industries come in threes

But why do industries converge to a handful of companies?

As an expert on mergers, I know the answer comes down to market forces relating to competition, which tends to drive consolidation of an industry into three to five firms.

From a customer perspective, there is a need for multiple options. Having more than one option avoids monopolistic practices that can see prices fixed at a higher rate. Competition between more than one big player is also a strong incentive for additional innovation to improve a product or service.

For these reasons, governments – in the U.S. and over 100 other countries – have antitrust laws and practices to avoid any industry displaying limited competition.

However, as industries become more stable, growth tends to slow and remaining businesses are forced to compete over a largely fixed market. This can separate companies into industry leaders and laggards. While leaders enjoy greater stability and predictable profits, laggards struggle to remain profitable.

Lagging companies often combine to increase their market share and reduce costs.

The result is that consolidating industries quite often land on three main players as a source of stability – one or two risks falling into the pitfalls of monopolies and duopolies, while many more than three to five can struggle to be profitable in mature industries.

What’s ahead for the laggards

The long-term viability of companies outside the “Big Three” streamers is in doubt, as the main players get bigger and smaller companies are unable to offer as much content.

A temporary solution for smaller streamers to gain subscribers is to offer teaser rates that later increase for people that forget to cancel until companies take more permanent steps. But lagging services will also face increased pressure to exit streaming by licensing content to the leading streaming services, cease operations or sell their services and content.

Additionally, companies outside the Big Three could be tempted to acquire smaller services in an attempt to maintain market share.

There are already rumors that Paramount, which was a competing bidder for Warner Bros., may seek to acquire Starz or create a joint venture with Universal, which owns Peacock.

Apple shows no immediate plan of discontinuing Apple TV+, but that may be due to the company’s high profitability and an overall cash flow that limits pressures to end its streaming service.

Still, if the Netflix-Warner Bros. deal completes, it will likely increase the valuation of other lagging streaming services due to increased scarcity of valuable content and subscribers. This is due to competitive limits that restrict the Big Three from getting bigger, making the combination of smaller streaming services more valuable.

This is reinforced by shareholders expecting similar or greater premiums from prior deals, driving the need to pay higher prices for the fewer remaining available assets.

The cost to consumers

So what does this all mean for consumers?

I believe that in general, consumers will largely not be impacted when it comes to the overall cost of entertainment, as inflationary pressures for food and housing limit available income for streaming services.

But where they access content will continue to shift away from cable television and movie theaters.

Greater stability in the streaming industry through consolidation into a Big Three model only confirms the decline in traditional cable.

Netflix’s rationale in acquiring Warner Bros. is likely to enable it to offer streaming at a lower price than the combined price of separate subscriptions, but more than Netflix alone.

This could be achieved through additional subscription tiers for Netflix subscribers wanting to add HBO Max content. Beyond competition with other members of the “Big Three,” another reason why Netflix is unlikely to raise prices significantly is that it will likely commit to not doing so in order to get the merger approved.

Netflix’s goal is to ensure it remains consumer’s first choice for streaming TV and films. So while streaming is fast becoming a Big Three industry, Netflix’s plan is to remain at the top of the triangle.

What 38 million obituaries reveal about how Americans define a ‘life well lived’

Obituaries provide a window into the prevailing traditions and moral values of their time. alexmillos/iStock via Getty Images Plus

Obituaries preserve what families most want remembered about the people they cherish most. Across time, they also reveal the values each era chose to honor.

In a study published in the journal Proceedings of the National Academy of Sciences, we analyzed 38 million obituaries of Americans published from 1998 to 2024. We identified the values families most often highlight, and how those values shift across generations, regions and major historical events.

Specifically, working with psychologists Liane Young and Thomas Mazzuchi, we examined the language used on Legacy.com, an online platform where families often post obituaries and share memories of loved ones.

During their lifetime, most people tend to be guided by a small set of broad values like caring for others, honoring tradition, keeping loved ones safe and seeking personal growth. To understand how these values showed up in remembrance, we used text-analysis tools built on curated lists of everyday words people use when talking about those themes.

By analyzing the words that appeared again and again in memorials, we could see which values communities chose to emphasize when looking back on the lives of their loved ones, and how those patterns changed over time. Because the dataset included 38 million obituaries, the analysis ran on a supercomputer.

Across nearly 30 years of obituaries, words related to the value “tradition” appeared most often – many tributes described religious participation and enduring customs. Words related to the value “benevolence” – caring for the welfare of others – were also consistently prominent. In fact, tradition and benevolence formed the dominant value profile across the dataset: They appeared in more than 70% of the obituaries. By contrast, words related to values like “achievement” and “power” appeared far less often.

Historical events did leave a mark. After the attacks of Sept. 11, 2001, the language families used to remember loved ones shifted compared with the period just before the attacks – and those shifts persisted for at least a year. Words related to the value “security” – including terms like “surviving,” “health” and “order” – showed up less often. At the same time, families used more language related to values like “benevolence” and “tradition.” Terms like “caring,” “loyal” and “service” showed up more often. These changes were especially strong in New York, where the attacks had the most direct impact.

COVID-19, however, produced the most dramatic shifts. Beginning in March 2020, benevolence-related language – including terms like “love,” “sympathy” and “family” – declined sharply, and hasn’t been the same since. Tradition-related language – terms like “service,” “faith” and “heritage” – initially declined as well, then rose above baseline levels during later stages of the pandemic.

These changes show that collective disruptions impact the moral vocabulary families use when commemorating loved ones. They shift what it means to have lived a good life.

We also saw differences that reflect stereotypes about gender and age. Obituaries for men contained more language linked to achievement, conformity and power. Meanwhile, obituaries for women contained more language associated with benevolence and enjoying life’s pleasures.

Older adults were often remembered more for valuing tradition. Younger adults, on the other hand, were often remembered more for valuing the welfare of all people and nature, and for being motivated to think and act independently. Value patterns in men’s obituaries shifted more across the lifespan than those in women’s. In other words, the values highlighted in younger and older men’s obituaries differed more from each other, while women’s value profiles stayed relatively consistent across age.

Why it matters

The most visited parts of print newspapers and online memorial sites, obituaries offer a window into what societies value at different points in time.

This study contributes to the broader scientific understanding of legacy. People often hold strong preferences about how they want to be remembered, but far less is known about how they actually are remembered, in part because large-scale evidence about real memorials is rare. Our analysis of millions of obituaries helps fill that gap.

What’s next

Obituaries allow researchers to trace cultural values across time, geography and social groups. Future work can examine differences across race and occupation, as well as across regions. It could also look to earlier periods using historical obituary archives, such as those preserved in older newspapers and local records.

Another direction is to examine whether highlighting how often kindness shows up in obituaries could inspire people to be more caring in daily life.

Understanding what endures in memory helps clarify what people consider meaningful; those values shape how they choose to live.

The Research Brief is a short take on interesting academic work.

Merry Jewish Christmas: How Chinese food and the movies became a time-honored tradition for American Jews

Source: The Conversation – USA (3) – By Samira Mehta, Associate Professor of Women and Gender Studies & Jewish Studies, University of Colorado Boulder

There is a meme that circulates every holiday season, an image of a sign in a restaurant window. “The Chinese Restaurant Association of the United States would like to extend our thanks to the Jewish people,” it says. “We do not completely understand your dietary customs … but we are proud and grateful that your GOD insists you eat our food on Christmas.”

Is the sign real? Perhaps not; the fact-checking site Snopes found no evidence of the association even existing. But the joke’s popularity points to a tradition cherished by many American Jews – Chinese food on Christmas.

But why would Jews, who do not celebrate Christmas, have Christmas traditions?

Like many minority groups, Jews have always created ways of adapting to the societies in which they live, but whose culture they do not totally share. And one thing that means is a collection of Christmas traditions, varying by time and place. Many of them came up in interviews for my book “Beyond Chrismukkah: The Christian-Jewish Interfaith Family in the United States.”

Old World festivities

Long before Jews came to the United States, some of them celebrated Christmas – participating in many of the cultural traditions, even as they avoided the religious part of the holiday.

According to Jordan Chad, author of “Christmas in Yiddish Tradition,” Jewish folklore about the holiday appears as early as the late 1300s. Plenty of Jewish communities in Europe spent Christmas Eve dancing and drinking, feasting and gambling – as many of their Christian neighbors did, when those neighbors were not in church.

Other scholars have argued that these traditions grew out of attempts to avoid studying Jewish religious texts on a Christian holiday. But Chad demonstrates that, over centuries, those customs came to celebrate the revelry of the season – though not the birth of Jesus.

Even in the 20th century, scholars such as Yaniv Feller have found, many middle- and upper-class German Jews embraced a secular Christmas, complete with a tree, a traditional dinner and presents. After all, some of those Christmas traditions stem less from religion than folk traditions and industrialization.

Given that long history, Jewish Christmas traditions are not necessarily a sign of Americanization.

That said, in the United States, Christmas is so culturally powerful – a day that almost everyone has off, and that the majority of Americans spend with their kith and kin – that many non-Christian immigrants celebrate it in a secular way, with family visits, Santa and a tree. They do not necessarily do the religious parts of the holiday, but they may well deck the halls. Certainly, my own Hindu relatives do.

And many Jews celebrate Christmas in some way because they are part of interfaith families – whether their own immediate family or extended relatives with whom they spend the day. Today, estimates place the American Jewish interfaith marriage rate as high as 50%.

Kosher-style Chinese

For plenty of contemporary Jews, however, it is profoundly important not to celebrate a secular version of Christmas. Starting in the 1970s, in fact, when American Jews were particularly worried about rising rates of interfaith marriage, many of the rabbis willing to perform ceremonies for Jewish-Christian couples made them promise to not have a Christmas tree. This happened despite the fact that, at the time, many American Jews did have Christmas trees in their homes.

Even if Jews do not want to deck the halls, though, many still have the day off. Meanwhile, their non-Jewish friends, families and co-workers are busy and much of the world is closed. And so many Jews have developed their own ways of marking the day.

The Chinese food tradition is particularly famous. In fact, during Supreme Court Justice Elena Kagan’s 2010 confirmation hearings, when Republican Sen. Lindsey Graham asked her where she had been on Christmas Day, she responded, “Like all Jews, I was probably at a Chinese restaurant.”

Elena Kagan’s Senate confirmation hearings made mention of the famous tradition.

The first written mention of Jews eating Chinese food on Christmas Day comes from 1935, when, according to The New York Times, a man named Eng Shee Chuck brought chow mein and toys to a New Jersey Jewish orphanage.

His generosity was probably not why Jews started going to Chinese restaurants on Christmas; it is more likely that they were already doing so. The two communities lived cheek by jowl in many American cities, where immigrants of different sorts ended up in the same neighborhoods. And Chinese food contains little dairy, meaning it rarely violated Jewish dietary laws against mixing milk and meat.

Most Chinese cuisines do use pork and shrimp, which is forbidden by kosher laws. But many Jewish customers were happy to make an exception, especially if the forbidden food was tucked in a dumpling or otherwise out of sight – at least outside their own homes.

As new research by New York University graduate student Shiyong Lu demonstrates, Chinese restaurants were also eager to cater to American Jews: They wanted to develop white, American clientele, and here were some right in their neighborhoods.

As restaurant owners learned that Jews often eschewed pork, some began to offer traditional dishes with chicken instead – allowing more observant Jews to eat “kosher style,” without eating explicitly forbidden food. Today, there is wide variation in Jewish dietary practices, making Chinese food even more accessible for most Jews.

By the end of the 20th century, “Chinese food and a movie” had become the trope of Jewish Christmas. Because most Chinese immigrants were not Christian, their restaurants are often open on Dec. 25. And indeed, they are often filled with Jews.

Movies, volunteering and more

The same tends to be true for movie theaters. In 2012, I saw “Les Misérables” on Christmas Day in a theater that seemed to be a who’s who of the Atlanta Jewish community. In fact, the movies and the Chinese food are often paired, whether out on the town or at home, streaming with take out.

Jewish museums are often open and are another popular destination in cities that have them. And some Jews use Christmas Day for travel. At least in eras past, plane tickets were notably cheaper than the days around the holiday.

Another Jewish Christmas tradition is simply to go to work, so as to let Christian colleagues have the day off. Many Jewish doctors and nurses are on call, or staff the emergency room or the intensive care unit, so that their colleagues can be home.

Still other Jews perform charitable deeds on Christmas: They staff soup kitchens and food banks, bring holiday cheer to nursing homes and hospital patients, or deliver gifts to children in shelters.

Living in a culture that largely closes down each Dec. 25, many Jews have found ways of making meaning in the day – be that sharing family time over beef and broccoli, followed by a holiday blockbuster, or working to make sure that more of their colleagues can have a family day. And those, too, are Christmas traditions.

Putting pig organs in people is OK in the US, but growing human organs in pigs is not – why is that?

Source: The Conversation – USA (3) – By Monika Piotrowska, Associate Professor of Philosophy, University at Albany, State University of New York

While research on human-pig chimeras is on an indefinite pause, xenotransplantation is moving ahead. wildpixel/iStock via Getty Images Plus

In a Maryland operating room one day in November 2025, doctors made medical history by transplanting a genetically modified pig kidney into a living patient. The kidney had been engineered to mimic human tissue and was grown in a pig, as an alternative to waiting around for a human organ donor who might never come. For decades, this idea lived at the edge of science fiction. Now it’s on the table, literally.

The patient is one of six taking part in the first clinical trial of pig-to-human kidney transplants. The goal: to see whether gene-edited pig kidneys can safely replace failing human ones.

A decade ago, scientists were chasing a different solution. Instead of editing the genes of pigs to make their organs human-friendly, they tried to grow human organs – made entirely of human cells – inside pigs. But in 2015 the National Institutes of Health paused funding for that work to consider its ethical risks. The pause remains today.

As a bioethicist and philosopher who has spent years studying the ethics of using organs grown in animals – including serving on an NIH-funded national working group examining oversight for research on human-animal chimeras – I was perplexed by the decision. The ban assumed the danger was making pigs too human. Yet regulators now seem comfortable making humans a little more pig.

Why is it considered ethical to put pig organs in humans but not to grow human organs in pigs?

Urgent need drives xenotransplantation

It’s easy to overlook the desperation driving these experiments. More than 100,000 Americans are waiting for organ transplants. Demand overwhelms supply, and thousands die each year before one becomes available.

For decades, scientists have looked across species for help – from baboon hearts in the 1960s to genetically altered pigs today. The challenge has always been the immune system. The body treats cells it does not recognize as part of itself as invaders. As a result, it destroys them.

A recent case underscores this fragility. A man in New Hampshire received a gene-edited pig kidney in January 2025. Nine months later, it had to be removed because its function was declining. While this partial success gave scientists hope, it was also a reminder that rejection remains a central problem for transplanting organs across species, also known as xenotransplantation.

Decades of research have led to the first clinical trial of pig kidney transplants.

Researchers are attempting to work around transplant rejection by creating an organ the human body might tolerate, inserting a few human genes and deleting some pig ones. Still, recipients of these gene-edited pig organs need powerful drugs to suppress the immune system both during and long after the transplant procedure, and even this may not prevent rejection. Even human-to-human transplants require lifelong immunosuppressants.

That’s why another approach – growing organs from a patient’s own cells – looked promising. This involved disabling the genes that let pig embryos form a kidney and injecting human stem cells into the embryo to fill the gap where a kidney would be. As a result, the pig embryo would grow a kidney genetically matched to a future patient, theoretically eliminating the risk of rejection.

Although simple in concept, the execution is technically complex because human and pig cells develop at different speeds. Even so, five years prior to the NIH ban, researchers had already done something similar by growing a mouse pancreas inside a rat.

Cross-species organ growth was not a fantasy – it was a working proof of concept.

Ethics of creating organs in other species

The worries motivating the NIH ban in 2015 on inserting human stem cells into animal embryos did not come from concerns about scientific failure but rather from moral confusion.

Policymakers feared that human cells might spread through the animal’s body – even into its brain – and in so doing blur the line between human and animal. The NIH warned of possible “alterations of the animal’s cognitive state.” The Animal Legal Defense Fund, an animal advocacy organization, argued that if such chimeras gained humanlike awareness, they should be treated as human research subjects.

The worry centers on the possibility that an animal’s moral status – that is, the degree to which an entity’s interests matter morally and the level of protection it is owed – might change. Higher moral status requires better treatment because it comes with vulnerability to greater forms of harm.

Think of the harm caused by poking an animal that’s sentient compared to the harm caused by poking an animal that’s self-conscious. A sentient animal – that is, one capable of experiencing sensations such as pain or pleasure – would sense the pain and try to avoid it. In contrast, an animal that’s self-conscious – that is, one capable of reflecting on having those experiences – would not only sense the pain but grasp that it is itself the subject of that pain. The latter kind of harm is deeper, involving not just sensation but awareness.

Thus, the NIH’s concern is that if human cells migrate into an animal’s brain, they might introduce new forms of experience and suffering, thereby elevating its moral status.

The flawed logic of the NIH ban

However, the reasoning behind the NIH’s ban is faulty. If certain cognitive capacities, such as self-consciousness, conferred higher moral status, then it follows that regulators would be equally concerned about inserting dolphin or primate cells into pigs as they are about inserting human cells. They are not.

In practice, the moral circle of beings whose interests matter is drawn not around self-consciousness but around species membership. Regulators protect all humans from harmful research because they are human, not because of their specific cognitive capacities such as the ability to feel pain, use language or engage in abstract reasoning. In fact, many people lack such capacities. Moral concern flows from that relationship, not from having a particular form of awareness. No research goal can justify violating the most basic interests of human beings.

If a pig embryo infused with human cells truly became something close enough to count as a member of the human species, then current research regulations would dictate it’s owed human-level regard. But the mere presence of human cells doesn’t make pigs humans.

The pigs engineered for kidney transplants already carry human genes, but they aren’t called half-human beings. When a person donates a kidney, the recipient doesn’t become part of the donor’s family. Yet current research policies treat a pig with a human kidney as if it might.

There may be good reasons to object to using animals as living organ factories, including welfare concerns. But the rationale behind the NIH ban that human cells could make pigs too human rests on a misunderstanding of what gives beings – and human beings in particular – moral standing.

Supreme Court’s decision on birthright citizenship will depend on its interpretation of one key phrase

Source: The Conversation – USA – By Morgan Marietta, Professor of American Civics, University of Tennessee

When the justices weigh the arguments, they will focus on the meaning of the first sentence of the 14th Amendment, known as the citizenship clause. zimmytws/Getty Images

The Supreme Court on Dec. 5, 2025, agreed to review the long-simmering controversy over birthright citizenship. It will likely hand down a ruling next summer.

In January 2025, President Donald Trump issued an executive order removing the recognition of citizenship for the U.S.-born children of both immigrants here illegally and visitors here only temporarily. The new rule is not retroactive. This change in long-standing U.S. policy sparked a wave of litigation culminating in Trump v. Washington, an appeal by Trump to remove the injunction put in place by federal courts.

When the justices weigh the arguments, they will focus on the meaning of the first sentence of the 14th Amendment, known as the citizenship clause: “All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside.”

Both sides agree that to be granted birthright citizenship under the Constitution, a child must be born inside U.S. borders and the parents must be “subject to the jurisdiction” of the United States. However, each side will give a very different interpretation of what the second requirement means. Who falls under “the jurisdiction” of the United States in this context?

As a close observer of the court, I anticipate a divided outcome grounded in strong arguments from each side.

Arguments for automatic citizenship

Simply put, the argument against the Trump administration is that the 14th Amendment’s expansion of citizenship after the eradication of slavery was meant to be broad rather than narrow, encompassing not only formerly enslaved Black people but all persons who arrived on U.S. soil under the protection of the Constitution.

The Civil War amendments – the 13th, 14th and 15th – established inherent equality as a constitutional value, which embraced all persons born in the nation without reference to race, ethnicity or origin.

One of the strongest arguments that automatic citizenship is the meaning of the Constitution is long-standing practice. Citizenship by birth regardless of parental status – with few exceptions – has been the effective rule since the time of America’s founding.

Advocates also point to precedent: the landmark case of United States v. Wong Kim Ark in 1898. When an American-born descendant of resident noncitizens sued after being refused re-entry to San Francisco under the Chinese Exclusion Act, the court recognized his natural-born citizenship.

If we read the Constitution in a living fashion – emphasizing the evolution of American beliefs and values over time – the constitutional commitment to broad citizenship grounded in equality, regardless of ethnicity or economic status, seems even more clear.

However, advocates must try to convince the court’s originalists – Clarence Thomas, Samuel Alito, Neil Gorsuch, Brett Kavanaugh and Amy Coney Barrett – who read the Constitution based on its meaning when it was adopted.

The originalist argument in favor of birthright citizenship is that the phrase “subject to the jurisdiction” was meant to invoke only a small set of exceptions found in traditional British common law. In the Wong Kim Ark ruling, the court relied on this “customary law of England, brought to America by the colonists.”

One exception to birthright citizenship covered by this line of rulings is the child of a foreign diplomat, whose parents represent the interests of another country. Another exception is the children of invading foreign armies. A third exception discussed explicitly by the framers of the 14th Amendment was Native Americans, who at the time were understood to be under the jurisdiction of their tribal government as a separate sovereign. That category of exclusion faded away after Congress recognized the citizenship of Native Americans in 1924.

The advocates of automatic birthright citizenship conclude that whether the 14th Amendment is interpreted in a living or in an original way, its small set of exceptions do not override its broad message of citizenship grounded in human equality.

Opposition to birthright citizenship

The opposing argument begins with a simple intuition: In a society defined by self-government, as America is, there is no such thing as citizenship without consent. In the same way that an American citizen cannot declare himself a French citizen and vote in French elections without consent from the French government, a foreign national cannot declare himself a U.S. citizen without consent.

This argument emphasizes that citizenship in a democracy means holding equal political power over our collective decisions. That is something only existing citizens hold the right to offer to others, something which must be decided through elections and the lawmaking process.

The court’s ruling in Elk v. Wilkins in 1884 – just 16 years after the ratification of the 14th Amendment – endorses “the principle that no one can become a citizen of a nation without its consent.” By making entry into the United States without approval a federal offense, Congress has effectively denied that consent.

Scholars who support this view argue that the 14th Amendment does not provide this consent. Instead it sets a limitation. To the authors of the 14th Amendment, “subject to the jurisdiction thereof” conveyed a limit to natural citizenship grounded in mutual allegiance. That means if people are free to deny their old national allegiance, and an independent nation is free to decide its own membership, the recognition of a new national identity must be mutual.

Immigrants living in the United States illegally have not accepted the sovereignty of the nation’s laws. On the other side of the coin, the government has not officially accepted them as residents under its protection.

If mutual recognition of allegiance is the meaning of the 14th Amendment, the Trump administration has not violated it.

The opponents of birthright citizenship argue that the Wong Kim Ark ruling has been misrepresented. In that case, the court only considered permanent legal residents like Wong Kim Ark’s parents, but not residents here illegally or temporarily. The focus on British common law in that ruling is simply misguided because the findings of Calvin’s Case or any other precedents dealing with British subjects were voided by the American Revolution.

In this view, the Declaration of Independence replaced subjects with citizens. The power to determine national membership was taken away from kings and placed in the hands of democratic majorities.

For opponents of birthright citizenship, the 14th Amendment does not take that power away from citizens but instead codifies the rule that mutual consent is the touchstone of admission. The requirement to be “subject to the jurisdiction” provides the mechanism of that consent.

Congress can determine who is accepted as a member of the national community under its jurisdiction. In this view, Congress – and the American people – have spoken: Current federal laws make entry into U.S. borders without permission a crime rather than a forced acceptance of political membership.

What might happen

The court will likely announce a ruling in summer 2026 before early July, just in time for the 250th anniversary of the Declaration of Independence. The court will ultimately decide whether the Constitution endorses the declaration’s invocation of essential equality or its creation of a sovereign people empowered to determine the boundaries of national membership.

The court’s three Democratic-appointed justices – Ketanji Brown Jackson, Elena Kagan and Sonia Sotomayor – will surely side against the Trump administration. The six Republican-appointed justices seem likely to divide, a symptom of disagreements within the originalist camp.

The liberal justices need at least two of the conservatives to join them to form a majority of five to uphold universal birthright citizenship. This will likely be some combination of Chief Justice John Roberts, Brett Kavanaugh and Amy Coney Barrett.

The Trump administration will prevail only if five out of the six conservatives reject the British common law foundations of the Wong Kim Ark ruling in favor of citizenship by consent alone.

America should know by July Fourth.

Supreme Court’s decision on birthright citizenship will depend on its interpretation of one phrase

The Supreme Court on Dec. 5, 2025, agreed to review the long-simmering controversy over birthright citizenship. It will likely hand down a ruling next summer.

In January 2025, President Donald Trump issued an executive order removing the recognition of citizenship for the U.S.-born children of both immigrants here illegally and visitors here only temporarily. The new rule is not retroactive. This change in long-standing U.S. policy sparked a wave of litigation culminating in Trump v. Washington, an appeal by Trump to remove the injunction put in place by federal courts.

When the justices weigh the arguments, they will focus on the meaning of the first sentence of the 14th Amendment, known as the citizenship clause: “All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside.”

Both sides agree that to be granted birthright citizenship under the Constitution, a child must be born inside U.S. borders and the parents must be “subject to the jurisdiction” of the United States. However, each side will give a very different interpretation of what the second requirement means. Who falls under “the jurisdiction” of the United States in this context?

As a close observer of the court, I anticipate a divided outcome grounded in strong arguments from each side.

Arguments for automatic citizenship

Simply put, the argument against the Trump administration is that the 14th Amendment’s expansion of citizenship after the eradication of slavery was meant to be broad rather than narrow, encompassing not only formerly enslaved Black people but all persons who arrived on U.S. soil under the protection of the Constitution.

The Civil War amendments – the 13th, 14th and 15th – established inherent equality as a constitutional value, which embraced all persons born in the nation without reference to race, ethnicity or origin.

One of the strongest arguments that automatic citizenship is the meaning of the Constitution is long-standing practice. Citizenship by birth regardless of parental status – with few exceptions – has been the effective rule since the time of America’s founding.

Advocates also point to precedent: the landmark case of United States v. Wong Kim Ark in 1898. When an American-born descendant of resident noncitizens sued after being refused re-entry to San Francisco under the Chinese Exclusion Act, the court recognized his natural-born citizenship.

If we read the Constitution in a living fashion – emphasizing the evolution of American beliefs and values over time – the constitutional commitment to broad citizenship grounded in equality, regardless of ethnicity or economic status, seems even more clear.

However, advocates must try to convince the court’s originalists – Clarence Thomas, Samuel Alito, Neil Gorsuch, Brett Kavanaugh and Amy Coney Barrett – who read the Constitution based on its meaning when it was adopted.

The originalist argument in favor of birthright citizenship is that the phrase “subject to the jurisdiction” was meant to invoke only a small set of exceptions found in traditional British common law. In the Wong Kim Ark ruling, the court relied on this “customary law of England, brought to America by the colonists.”

One exception to birthright citizenship covered by this line of rulings is the child of a foreign diplomat, whose parents represent the interests of another country. Another exception is the children of invading foreign armies. A third exception discussed explicitly by the framers of the 14th Amendment was Native Americans, who at the time were understood to be under the jurisdiction of their tribal government as a separate sovereign. That category of exclusion faded away after Congress recognized the citizenship of Native Americans in 1924.

The advocates of automatic birthright citizenship conclude that whether the 14th Amendment is interpreted in a living or in an original way, its small set of exceptions do not override its broad message of citizenship grounded in human equality.

Opposition to birthright citizenship

The opposing argument begins with a simple intuition: In a society defined by self-government, as America is, there is no such thing as citizenship without consent. In the same way that an American citizen cannot declare himself a French citizen and vote in French elections without consent from the French government, a foreign national cannot declare himself a U.S. citizen without consent.

This argument emphasizes that citizenship in a democracy means holding equal political power over our collective decisions. That is something only existing citizens hold the right to offer to others, something which must be decided through elections and the lawmaking process.

The court’s ruling in Elk v. Wilkins in 1884 – just 16 years after the ratification of the 14th Amendment – endorses “the principle that no one can become a citizen of a nation without its consent.” By making entry into the United States without approval a federal offense, Congress has effectively denied that consent.

Scholars who support this view argue that the 14th Amendment does not provide this consent. Instead it sets a limitation. To the authors of the 14th Amendment, “subject to the jurisdiction thereof” conveyed a limit to natural citizenship grounded in mutual allegiance. That means if people are free to deny their old national allegiance, and an independent nation is free to decide its own membership, the recognition of a new national identity must be mutual.

Immigrants living in the United States illegally have not accepted the sovereignty of the nation’s laws. On the other side of the coin, the government has not officially accepted them as residents under its protection.

If mutual recognition of allegiance is the meaning of the 14th Amendment, the Trump administration has not violated it.

The opponents of birthright citizenship argue that the Wong Kim Ark ruling has been misrepresented. In that case, the court only considered permanent legal residents like Wong Kim Ark’s parents, but not residents here illegally or temporarily. The focus on British common law in that ruling is simply misguided because the findings of Calvin’s Case or any other precedents dealing with British subjects were voided by the American Revolution.

In this view, the Declaration of Independence replaced subjects with citizens. The power to determine national membership was taken away from kings and placed in the hands of democratic majorities.

For opponents of birthright citizenship, the 14th Amendment does not take that power away from citizens but instead codifies the rule that mutual consent is the touchstone of admission. The requirement to be “subject to the jurisdiction” provides the mechanism of that consent.

Congress can determine who is accepted as a member of the national community under its jurisdiction. In this view, Congress – and the American people – have spoken: Current federal laws make entry into U.S. borders without permission a crime rather than a forced acceptance of political membership.

What might happen

The court will likely announce a ruling in summer 2026 before early July, just in time for the 250th anniversary of the Declaration of Independence. The court will ultimately decide whether the Constitution endorses the declaration’s invocation of essential equality or its creation of a sovereign people empowered to determine the boundaries of national membership.

Vaccine committee votes to scrap universal hepatitis B shots for newborns despite outcry from children’s health experts

The committee advising the Centers for Disease Control and Prevention on vaccine policy voted on Dec. 5, 2025, to stop recommending that all newborns be routinely vaccinated against the hepatitis B virus – undoing a 34-year prevention strategy that has nearly eliminated early childhood hepatitis B infections in the United States.

Before the U.S. began vaccinating all infants at birth with the hepatitis B vaccine in 1991, around 18,000 children every year contracted the virus before their 10th birthday – about half of them at birth. About 90% of that subset developed a chronic infection.

In the U.S., 1 in 4 children chronically infected with hepatitis B will die prematurely from cirrhosis or liver cancer.

Today, fewer than 1,000 American children or adolescents contract the virus every year – a 95% drop. Fewer than 20 babies each year are reported infected at birth.

I am a pediatrician and preventive medicine specialist who studies vaccine delivery and policy. Vaccinating babies for hepatitis B at birth remains one of the clearest, most evidence-based ways to keep American children free of this lifelong, deadly infection.

What spurred the change?

In September 2025, the Advisory Committee on Immunization Practices, or ACIP, an independent panel of experts that advises the CDC, debated changing the recommendation for a dose of the hepatitis B vaccine at birth, but ultimately delayed the vote.

This committee regularly reviews vaccine guidance. However, since Secretary of Health and Human Services Robert F. Kennedy Jr. disbanded the entire committee and handpicked new members, its activity has drastically departed from business as usual. The committee has long-standing procedures for evaluating evidence on the risks and benefits of vaccines, but these procedures were not followed in the September meeting and were not followed for this most recent decision.

The committee’s new recommendation keeps the hepatitis B vaccine at birth for infants whose mothers test positive for the virus. But the committee now advises that infants whose mothers test negative should consult with their health care provider. Parents and health care providers are instructed to weigh vaccine benefits, vaccine risks and infection risks using “individual-based decision-making” or “shared clinical decision-making.”

The hepatitis B vaccine has an outstanding safety record and has been administered to billions of infants at birth.

On the surface, this sounds reasonable. But while parents have always been free to discuss benefits and risks with their health care providers to make a decision on what’s best for their child, this change is not based on any new evidence, and it introduces uncertainty into a recommendation that has long been clear.

As a doctor, I am already seeing this uncertainty play out in the clinic. I recently had new parents ask to postpone the hepatitis B vaccine until adolescence because they believed federal health leaders had evidence that people only become infected through sexual activity or contaminated needle use.

After a brief conversation, they came to understand that this was inaccurate — children can be infected not only at birth but also through routine household or child care exposures, including shared toothbrushes or even a bite that breaks the skin. In the end, they chose to vaccinate, but this experience highlights how easily well-intentioned parents can be misled when guidance is not clear and consistent.

Why the CDC adopted universal hepatitis B shots

Hepatitis B is a virus that infects liver cells, causing inflammation and damage. It is spread through blood and bodily fluids and is easily transmitted from mother to baby during delivery.

The hepatitis B vaccine has been available since the early 1980s. Before 1991, public health guidance recommended giving newborns the hepatitis B vaccine only if they were at high risk of being infected – for example, if they were born to a mother infected with hepatitis B.

That targeted plan failed. Tens of thousands of infants were still infected each year.

Some newborns were exposed when their mothers weren’t screened; others were exposed after their mothers were infected late in pregnancy, after their initial screening. And like any lab test, the screening can have false negative results, be misinterpreted or not be communicated properly to the baby’s care team.

Recognizing these gaps, in 1991 the CDC recommended hepatitis B vaccination for every child starting at birth, regardless of maternal risk.

The U.S. adopted a policy of vaccinating all babies from birth because the number of people with hepatitis B infections was, and remains, relatively high, and because many mothers do not receive prenatal care, so their infections go undetected.

Meanwhile, in some European countries, like Denmark, only babies with certain risk factors receive the vaccine at birth. That’s because in those countries, hepatitis B infections are much less prevalent and pregnant mothers are more widely tested due to universal health care. Due to these differences, that approach is not effective in the United States. In fact, most World Health Organization member countries do recommend a universal birth dose.

Vaccinating at birth

The greatest danger for infants contracting hepatitis B is at birth, when contact with a mother’s blood can transmit the virus. Without preventive treatment or vaccination, 70% to 90% of infants born to infected mothers will become infected themselves, and 90% of those infections will become chronic. The infection in these children silently damages their liver, potentially leading to liver cancer and death.

About 80% of parents choose to vaccinate their babies at birth. If parents choose to delay vaccination due to this new recommendation, it will leave babies unprotected during this most vulnerable window, when infection is most likely to lead to chronic infection and silently damage the liver.

A research article published on Dec. 3, 2025, estimates that if only infants born to mothers infected with hepatitis B received the vaccine, an additional 476 perinatal hepatitis B infections would occur each year.

The hepatitis B vaccines used in the U.S. have an outstanding safety record. The only confirmed risk is an allergic reaction called anaphylaxis that occurs in roughly 1 in 600,000 doses, and no child has died from such a reaction. Extensive studies show no link to other serious conditions.

How children get exposed to hepatitis B

Infants and children continue to be vulnerable to hepatitis B long after birth.

Children can become infected through household contacts or in child care settings by exposures as ordinary as shared toothbrushes or a bite that breaks the skin. Because hepatitis B can survive for a week on household surfaces, and many carriers are unaware they are infected, even babies and toddlers of uninfected mothers remained at risk.

Full protection against hepatitis B requires a three-dose vaccine series, given at specific intervals in infancy. Anything short of the full series leaves children vulnerable for life.

In addition to changing the birth dose recommendation, the committee is now advising parents to consult with their health care provider about checking children’s antibody levels after one or two doses of the vaccine to determine whether additional doses are needed. While such testing is sometimes recommended for people in high-risk groups after they get all three doses to confirm their immune system properly responded to the vaccine, it is not a substitute for completing the series.

The recommendation for all babies to receive the vaccine at birth and for infants to complete the full vaccine series is designed to protect every child, including those who slip through gaps in maternal screening or encounter the virus in everyday life. A reversion to the less effective risk-based approach threatens to erode this critical safety net.

3 states are challenging precedent against posting the Ten Commandments in public schools – cases that could land back at the Supreme Court

As disputes rage on over religion’s place in public schools, the Ten Commandments have become a focal point. At least a dozen states have considered proposals that would require the posting of the Ten Commandments in classrooms, with Texas, Louisiana and Arkansas mandating their display in 2024 or 2025.

Challenges led to all three laws being at least partially blocked. Most recently, on Dec. 2, 2025, families in Texas filed a class-action lawsuit seeking to take down displays across the state. Federal trial court judges have already temporarily blocked the law in around two dozen districts. Ongoing appeals from the bills’ supporters, though, seem aimed at overturning a 45-year-old U.S. Supreme Court precedent prohibiting such displays.

As religion and education law researchers, we believe this situation is especially noteworthy because of its timing. In 2022, the Supreme Court adopted a new standard to assess religious freedom cases, which may come into play – and its judgments on religion’s role in public education are perhaps the most religion-friendly they have ever been.

The Ten Commandments and the courts

Controversy over the commandments is not new. In more than a dozen early cases, courts generally upheld laws and policies mandating their recitation in schools. These enactments survived because the Supreme Court did not extend the First Amendment to state laws until 1940.

Litigation over posting the Ten Commandments in schools first reached the Supreme Court in 1980. In Stone v. Graham, the justices invalidated a Kentucky statute requiring displays of the commandments in classrooms. The court reasoned that the law violated the First Amendment’s establishment clause: “Congress shall make no law respecting an establishment of religion.”

At the time, the court applied the first of the three criteria it has since abandoned, known as the “Lemon test,” to evaluate whether governmental action violates the establishment clause. Under this test – which developed from a 1971 Supreme Court decision – governmental actions must have a secular legislative purpose, and their main effect may neither advance nor inhibit religion. In addition, they must avoid excessive entanglement with religion.

In Stone, the justices rejected Kentucky’s argument that the displays served a secular educational purpose. The court disagreed that a small notation on posters describing the Ten Commandments as the “fundamental legal code of Western Civilization and the Common Law of the United States” was sufficient, noting that the posters were “plainly religious in nature.”

Twenty-five years later, in 2005, litigation over public displays of the Ten Commandments returned to the Supreme Court. This time, neither display was in a school.

The first dispute arose in Kentucky, where officials in two counties had erected courthouse displays including the Ten Commandments, the Magna Carta and the Declaration of Independence. The justices limited their order to one dispute, in McCreary County, invalidating the display for violating the establishment clause – largely because it lacked a secular legislative purpose.

On the same day, the Supreme Court reached the opposite result in another case, Van Orden v. Perry. The court permitted a display including the Ten Commandments to remain on the grounds of the Texas Capitol in Austin, where it was one of 17 monuments and 21 historical markers.

Unlike the fairly new displays in Kentucky, the long-standing one in Texas, with the first monument erected in 1891, was built using private funds. The court left the Ten Commandments monument in place because it was a more passive display. The Capitol grounds are spread out over 22 acres, meaning the Ten Commandments were not as readily apparent as if they had been posted in classrooms.

‘Follow God’s law’

More recent controversy started in 2024. Louisiana mandated that the Ten Commandments be posted in public schools, and a federal trial court soon blocked the law. Undeterred, Arkansas and Texas passed similar legislation the following year.

Arkansas Act 573, signed into law in April 2025, obligated officials to display a “durable poster or framed copy” of the Ten Commandments in all state and local government buildings, including public school and college classrooms.

Republican Rep. Alyssa Brown, one of the Arkansas bill’s sponsors, described it as an effort to educate students on how the United States was founded and how the founders framed the Constitution.

“We’re not telling every student they have to believe in this God,” she told a legislative committee, “but we are upholding what those historical documents mean and that historical national motto.”

Texas, meanwhile, adopted a similar law in June 2025.

“It is incumbent on all of us to follow God’s law, and I think we would all be better off if we did,” the bill’s sponsor in the Texas House, Republican Rep. Candy Noble, said during debate.

Shift at SCOTUS

Supporters of these laws argue that they are constitutional because of an important shift at the Supreme Court. In 2022, the court adopted a new “history and tradition test” to assess religion in public places, including classrooms.

The “history and tradition test” originated in 2022’s Kennedy v. Bremerton School District, a case about a public high school football coach who prayed on the field at the end of games. The court ruled that school officials could not prevent the coach from praying because it was a personal religious observance protected by the First Amendment’s other religion clause: that the government shall not prohibit the “free exercise” of religion.

The Kennedy case charted a new course on religion’s place in public life. Acknowledging that it “long ago abandoned Lemon and its endorsement test offshoot,” the justices explained that “the Establishment Clause must be interpreted by ‘reference to historical practices and understandings.‘” It remains to be seen how this standard plays out.

Blocked – for now

In August 2025, a federal trial court temporarily barred officials in four school districts from enforcing Arkansas’ law. The court found that the required display would have “forced [students] to engage with” the Ten Commandments, and “perhaps to venerate and obey” them. The court also applied the new historical practices and understandings test, holding that there was no evidence of a tradition to display the Ten Commandments in public schools permanently.

The same judge later prohibited two more Arkansas school boards from posting displays.

In Louisiana, too, a federal trial court blocked a state statute. The 5th U.S Circuit Court of Appeals initially affirmed that order. However, an en banc panel of the 5th Circuit – meaning all the circuit’s active judges – will rehear the case on Jan. 20, 2026.

The Texas statute’s future is also up in the air. In August 2025, a federal trial court enjoined the law, temporarily stopping it from going into effect in 11 districts. Acknowledging the cases from Arkansas and Louisiana, the judge held that Texas’ law likely violated the First Amendment. The full 5th Circuit will hear oral arguments in January, alongside the Louisiana case.

On Nov. 18, a second federal trial court judge enjoined the Texas law in around a dozen new districts.

Religion’s role

Controversy over the Ten Commandments continues to raise larger questions over the role of religion in public education, if any.

Supporters of such bills seemingly fail to recognize that they cannot impose their religious values in the public sphere. At the same time, some opponents – including Jewish, Christian, Unitarian Universalist, Hindu and nonreligious plaintiffs – do not necessarily wish to remove religion entirely from educational institutions.

These critics want to uphold the principle that, as the Supreme Court has affirmed, the government must demonstrate “neutrality between religion and religion, and between religion and nonreligion.” In other words, critics do not want one religion or religion generally to dominate.

Today’s challenge is to find the balance in public life. We believe the courts and legislatures must avoid sending the message that religion has no place in a free and open society – just as they must not permit one set of values to dominate, as the bills in Arkansas, Louisiana and Texas seem to aspire to do.

How the courts and legislatures balance the rights of the majority and minority in these disputes over the place of the Ten Commandments in public life may go a long way toward shaping the future of religious freedom in American public education.

Among high school students and adults, girls and women are much more likely to use traditional, step-by-step algorithms to solve basic math problems – such as lining up numbers to add, starting with the ones place, and “carrying over” a number when needed. Boys and men are more likely to use alternative shortcuts, such as rounding both numbers, adding the rounded figures, and then adjusting to remove the rounding.

But those who use traditional methods on basic problems are less likely to solve more complex math problems correctly. These are the main findings of two studies our research team published in November 2025.

This new evidence may help explain an apparent contradiction in the existing research – girls do better at math in school, but boys do better on high-stakes math tests and are more likely to pursue math-intensive careers. Our research focuses not just on getting correct answers, but on the methods students use to arrive at them. We find that boys and girls approach math problems differently, in ways that persist into adulthood.

A possible paradox

In a 2016 study of U.S. elementary students, boys outnumbered girls 4 to 1 among the top 1% of scorers on a national math test. And over many decades, boys have been about twice as likely as girls to be among the top scorers on the SAT and AP math exams.

However, girls tend to be more diligent in elementary school and get better grades in math class throughout their schooling. And girls and boys across the grades tend to score similarly on state math tests, which tend to be more aligned with the school curriculum and have more familiar problems than the SAT or other national tests.

Beyond grades and test scores, the skills and confidence acquired in school carry far beyond, into the workforce. In lucrative STEM occupations, such as computer science and engineering, men outnumber women 3 to 1. Researchers have considered several explanations for this disparity, including differences in math confidence and occupational values, such as prioritizing helping others or making money. Our study suggests an additional factor to consider: gender differences in approaches to math problems.

When older adults think of math, they may recall memorizing times tables or doing the tedious, long-division algorithm. Memorization and rule-following can pay off on math tests focused on procedures taught in school. But rule-following has its limits and seems to provide more payoff among low-achieving than high-achieving students in classrooms.

More advanced math involves solving new, perplexing problems rather than following rules.

Differing strategies

In looking at earlier studies of young children, our research team was struck by findings that young boys use more inventive strategies on computation problems, whereas girls more often use standard algorithms or counting. We wondered whether these differences disappear after elementary school, or whether they persist and relate to gender disparities in more advanced math outcomes.

In an earlier study, we surveyed students from two high schools with different demographic characteristics to see whether they were what we called bold problem-solvers. We asked them to rate how much they agreed or disagreed with specific statements, such as “I like to think outside the box when I solve math problems.” Boys reported bolder problem-solving tendencies than girls did. Importantly, students who reported bolder problem-solving tendencies scored higher on a math problem-solving test we administered.

Our newer studies echo those earlier results but reveal more specifics about how boys and girls, and men and women, approach basic math problems.

Algorithms and teacher-pleasing

In the first study, we gave three questions to more than 200 high school students: “25 x 9 = ___,” “600 – 498 = ___,” and “19 + 47 + 31 = ___.” Each question could be solved with a traditional algorithm or with a mental shortcut, such as solving 25 x 9 by first multiplying 25 x 8 to get 200 and then adding the final 25 to get 225.

Regardless of their gender, students were equally likely to solve these basic computation items correctly. But there was a striking gender difference in how they arrived at that answer. Girls were almost three times as likely as boys – 52% versus 18% – to use a standard algorithm on all three items. Boys were far more likely than girls – 51% versus 15% – to never use an algorithm on the questions.

We suspected that girls’ tendency to use algorithms might stem from greater social pressure toward compliance, including complying with traditional teacher expectations.

So, we also asked all the students eight questions to probe how much they try to please their teachers. We also wanted to see whether algorithm use might relate to gender differences in more advanced problem-solving, so we gave students several complex math problems from national tests, including the SAT.

As we suspected, we found that girls were more likely to report a desire to please teachers, such as by completing work as directed. Those who said they did have that desire used the standard algorithm more often.

Also, the boys in our sample scored higher than the girls on the complex math problems. Importantly, even though students who used algorithms on the basic computation items were just as likely to compute these items correctly, algorithm users did worse on the more complex math problems.

Continuing into adulthood

In our second study, we gave 810 adults just one problem: “125 + 238 = ___.” We asked them to add mentally, which we expected would discourage them from using an algorithm. Again, there was no gender difference in answering correctly.

But 69% of women, compared to 46% of men, reported using the standard algorithm for their mental calculation, rather than using another strategy entirely.

We also gave the adults a more advanced problem-solving test, this time focused on probability-related reasoning, such as the chances that rolling a seven-sided die would result in an even number. Similar to our first study, women and those who used the standard algorithm on the computation problem performed worse on the reasoning test.

The importance of inventiveness

We identified some factors that may play a role in these gender differences, including spatial-thinking skills, which may help people develop alternate calculation approaches. Anxiety about taking tests and perfectionism, both more prevalent among women, may also be a factor.

We are also interested in the power of gender-specific social pressures on girls. National data has shown that young girls exhibit more studious behavior than do boys. And the high school girls we studied were more likely than boys to report they made a specific effort to meet teachers’ expectations.

More research definitely is needed to better understand this dynamic, but we hypothesize that the expectation some girls feel to be compliant and please others may drive teacher-pleasing tendencies that result in girls using algorithms more frequently than boys, who are more socialized to be risk-takers.

While compliant behavior and standard math methods often lead to correct answers and good grades in school, we believe schools should prepare all students – regardless of gender – for when they face unfamiliar problems that require inventive problem-solving skills, whether in daily life, on high-stakes tests or in math-intensive professions.
