The U.S. Supreme Court has cleared the way for a chain of crisis pregnancy centers based in New Jersey to challenge a subpoena from New Jersey’s attorney general.

First Choice Women’s Resource Centers operates at several locations throughout New Jersey. There are more than 2,500 of these Christian-led nonprofits in the United States. Most try to discourage pregnant women from obtaining abortions. Some offer free medical services, such as over-the-counter pregnancy tests and sonograms. Many give their clients clothing, diapers and other items that the parents of babies require.

First Choice caught the attention of Matthew Platkin in 2023 while he served as the state’s attorney general. He suspected that it violated New Jersey’s Consumer Fraud Act by misleading its donors about its mission and operations. According to court filings, Platkin wanted to determine if First Choice had misled its donors and patients into believing that the centers provide “comprehensive reproductive health care services, including abortion care and contraception, when they in fact have an objective of deterring individuals from seeking such services.”

As part of New Jersey’s investigation, Platkin issued a subpoena demanding that First Choice produce donation records, including the personal information of the donors, over a 10-year period so that his office could “contact a representative sample” of them to determine if they had “been misled” by First Choice about what the group does – that is, whether or not it provided abortions.

First Choice asserted that the subpoena violated its First Amendment rights, and that it had a right to sue New Jersey’s attorney general in federal court to quash the subpoena.

The Supreme Court sided with First Choice in its unanimous ruling on First Choice Women’s Resource Centers, Inc. v. Davenport. The case now bears the name of New Jersey’s current attorney general, Jennifer Davenport.

In my view as a privacy and constitutional law scholar, the court ruled correctly by concluding that issuing a subpoena for personal information regarding a crisis pregnancy center’s donors may deter those donors from supporting the organization.

Quashing New Jersey’s subpoena

After First Choice sued to block the subpoena, Platkin argued that federal courts lacked jurisdiction to decide the case. That’s because First Choice’s alleged injury – deterring donors from supporting the organization – had not yet materialized because New Jersey had not yet tried to enforce the subpoena in court.

In other words, Platkin argued that the case was premature.

But First Choice argued that merely issuing a subpoena can deter donors from making a gift. To further its argument, First Choice presented what it said was an “anonymous declaration from several donors describing the present chill on their First Amendment-protected association.” In its view, the injury was real and concrete enough for the federal courts to decide the case.

The justices have now cleared the way for First Choice to continue with its lawsuit against New Jersey authorities in federal court.

Court ruled on a related case in 2018

The First Choice case might sound similar to a case the court decided in 2018.

In National Institute of Family and Life Advocates v. Becerra, the Supreme Court considered a different First Amendment claim asserted by a California-based organization that counsels crisis pregnancy centers.

In 2015, California enacted the Reproductive Freedom, Accountability, Comprehensive Care, and Transparency Act, better known as the Reproductive FACT Act. That law required clinics to inform their patients of California’s free or low-cost access to family-planning services, prenatal care and abortion. Several anti-abortion groups objected to California’s mandate, claiming the Reproductive FACT Act unconstitutionally compelled crisis pregnancy centers to disclose a message they do not support.

The Supreme Court agreed. Justice Clarence Thomas, writing for the court, concluded that the Reproductive FACT Act required clinics to “provide a government-drafted script about the availability of state-sponsored activities” that the clinics opposed.

In the court’s view, this violated the clinics’ First Amendment rights because it compelled them to speak a message containing an implicit viewpoint – support for abortion – that the clinics fundamentally opposed.

Both cases sit at the intersection of abortion politics and the First Amendment, but they raise distinct questions. The prior one, which addressed California’s attempt to regulate crisis pregnancy centers, asked whether the government can force those centers to make mandated statements. This new one, First Choice, asks whether the government can force the centers to disclose their donors’ identities.

Precedent set in an old NAACP case

The court has found previously that donations are a form of protected speech, including in its Citizens United v. Federal Elections Commission ruling. In that 2010 decision, the majority recognized that “All speakers, including individuals … use money amassed from the economic marketplace to fund their speech.”

As Justice Neil Gorsuch wrote in the Free Choice ruling, each right protected by the First Amendment “necessarily carries with it a corresponding right to associate with others.” Without such a right, he added, “no two men could safely share the same soapbox.”

This crisis pregnancy center ruling also reaffirms what the court decided about seven decades earlier in NAACP v. Alabama. The NAACP, founded in 1909, is one of the nation’s biggest civil rights groups.

In this 1958 ruling, the court concluded that any government actions that “may have the effect of curtailing the freedom to associate” warrant the highest form of protection under the First Amendment.

That ruling protected the privacy of NAACP members in Alabama. While there were no donors involved in that case, I believe that the rights of donors in the First Choice case are analogous to the rights of the NAACP’s members in the 1958 case – in that both have the right to the protection of their privacy.

In the 1950s, Alabama Attorney General John Patterson wanted to shut down the local NAACP chapter, based on his belief that the civil rights organization was “causing irreparable injury to the property and civil rights of the residents and citizens of the State of Alabama” by operating within the state as an unincorporated association.

As a part of his effort to oust the NAACP from Alabama, Patterson sought the membership lists of the local chapter, which, if disclosed, would have unquestionably caused “intimidation, vilification, economic reprisals, and physical harm.”

Similarly, in the 2026 First Choice case, Gorsuch, who wrote the 9-0 decision, “demands for private donor information inevitably carry with them a deterrent effect on the exercise of First Amendment rights.”

That is similar to Alabama’s demand for the NAACP’s membership list in 1958.

“It is hardly a novel perception that compelled disclosure of affiliation with groups engaged in advocacy may constitute as effective a restraint on freedom of association,” Supreme Court Justice John Marshall Harlan II declared in the ruling, which essentially shut down Alabama’s effort to ban the NAACP.

“This Court has recognized the vital relationship between freedom to associate and privacy in one’s associations,” Harlan added.

How to read this ruling

Many conservatives today will surely see the court’s decision as a win for the anti-abortion movement and its associated organizations. And many progressives will perceive it as another ruling from a supermajority conservative court that favors the rights of Americans who oppose access to abortion over those who support abortion rights.

The court, for example, overturned the nationwide right to abortion in 2022 in its Dobbs v. Jackson’s Women’s Health Organization ruling.

I think both interpretations are wrong because this case is more about free speech than abortion.

The fundamental principle the court asserted in NAACP v. Alabama remains intact – there is a vital relationship between the right to privacy and the freedom to associate.

Since its ratification in 1791, the First Amendment has protected much more than the rights that are expressly mentioned in its text. It protects the right to speak freely, just as it protects the right not to speak and the right to speak anonymously.

The First Amendment protects the right to associate with groups and organizations, just as it protects the right to associate with those groups and organizations anonymously.

It protects the right to think freely, to hold certain beliefs and to reject others. And as the Supreme Court reaffirmed in the First Choice case, the First Amendment protects individuals’ rights to associate with organizations that align with their beliefs by donating to them.

Supreme Court’s ‘shadow docket’ brings hasty decisions with long-lasting implications, outside of its usual careful deliberation

The recent publication of confidential Supreme Court memoranda by The New York Times has brought to light a pivotal moment in the court’s history. “The birth of the Supreme Court’s shadow docket has long been a mystery,” wrote reporters Jodi Kantor and Adam Liptak. “Until now.”

Originally coined by legal scholar William Baude, the term “shadow docket” refers to the Supreme Court’s emergency docket, which, as Baude wrote, includes “a range of orders and summary decisions that defy its normal procedural regularity.”

That’s law professor-speak for cases that are given abbreviated consideration and accelerated review by the justices, all out of public view – what The New York Times story referred to as the court “sprinting.” These cases aren’t included in the annual list of cases the justices have chosen to consider and that are presented by attorneys in public sessions, called “oral argument,” at the court.

During the second Trump administration, such shadow docket cases have proliferated as President Donald Trump has continued to push boundaries, challenge precedents and expand executive power. These cases have typically involved a request by the presidential administration “to suspend lower court orders” that temporarily block “an administration policy from taking effect,” according to liberal legal advocacy group the Brennan Center for Justice at New York University School of Law.

The lack of transparency in considering and ruling on the shadow docket, combined with the weight of the issues presented to the court via that docket, mean that the practice has come under strong criticism by many court watchers. Here’s how the process works and what you need to know to evaluate it.

The merits docket

The emergency docket is different from the court’s merits docket, which is the customary path for cases to reach the Supreme Court.

Ordinarily, in federal courts, a case begins in a federal district court. An appeal of the decision in the case is made to a federal appeals court. If a party in the case wants to appeal further, they can aim for U.S. Supreme Court review. That requires filing a “petition for writ of certiorari” to the court.

The Supreme Court does not take all the cases for which it has been petitioned. The court holds complete discretion to choose which cases to consider each term and always rejects the vast majority of petitions that it receives. By custom, the court agrees to consider a case if at least four justices vote to grant the writ of certiorari.

For the cases that the court agrees to consider, the parties to that case file briefs – written legal arguments – with the Supreme Court. Third parties can also file briefs with the court to assert their own arguments; these are known as “friend of the court” or amicus curiae briefs.

The justices then read those briefs and hear oral arguments in the case in a public session, during which they can question attorneys for both sides, before they meet and confer. At the end of this conference, the justices vote on the outcome in the case before assigning an author to draft the opinions.

The merits docket – the ordinary process – is methodical. It promotes deliberation and reasoned decision-making resulting in lengthy opinions that explain the justices’ rationale and provide guidance for lower courts in future cases.

The emergency docket

On the other hand, the emergency docket is a process whereby the court makes quick decisions without full briefing and deliberation, and it produces orders and rulings that almost always present little to no explanation.

As Baude wrote, “Many of the orders lack the transparency that we have come to appreciate in its merits cases.”

Most of the court’s rulings and orders in cases on the emergency docket go without explanation. On occasion, however, the court produces short opinions that provide some explanation in emergency docket cases, albeit these are often dissents from the justices who disagree with the ruling.

Transparency is important, especially for the Supreme Court, because it builds trust and legitimacy. According to Gallup, as of September 2025, 42% of respondents approve, 52% disapprove and 6% have no opinion of the Supreme Court. A 2025 Pew Research Center poll found that 48% of Americans have a favorable view of the court, down from 70% five years earlier.

As a constitutional law scholar, I’ve written elsewhere that the low approval might be attributable to the court’s undisciplined overruling of landmark cases regarding individual rights, such as the abortion rights case Roe v. Wade. In my view, it is reasonable to conclude that the court’s lack of transparency, specifically with its growing emergency docket, contributes to distrust in the court.

As the late Justice Sandra Day O’Connor stated, “The Court’s power lies … in its legitimacy, a product of substance and perception that shows itself in the people’s acceptance of the Judiciary as fit to determine what the Nation’s law means and to declare what it demands.”

Conversely, a lack of transparency breeds distrust and erodes institutional legitimacy.

Unprecedented action

The 2016 case at the center of the memoranda published by The New York Times –West Virginia v. EPA – concerned environmental regulation. As the justices’ memoranda illustrate, West Virginia, North Dakota and several energy companies sued the Obama administration over its Clean Power Plan and sought to block the new, transformative regulation from going into effect.

The Clean Power Plan would have required states and energy companies to shift electricity production from higher-emitting to lower-emitting production methods to reduce carbon dioxide emissions.

After losing at the trial court, the states and energy companies filed an emergency appeal to the Supreme Court asking the justices to pause the Obama regulation from going into effect while the parties litigated the case in the lower courts.

This was a highly unusual request because, as Taraleigh Davis at SCOTUSblog confirms, “nobody had previously asked the court to halt such a major executive regulatory action before any appellate court had ruled on it.”

The court granted the unprecedented stay on Feb. 9, 2016, without any explanation as to why it temporarily blocked the Clean Power Plan. It eventually struck down the plan on June 22, 2022.

Defenders of the emergency docket frequently claim that the court’s conduct is permissible because its orders are temporary. In West Virginia v. EPA, the court temporarily blocked the Clean Power Plan from going into effect until it eventually struck it down after hearing the case on its merits docket.

What is overlooked, however, is that even temporary orders from the court can have lasting implications that are difficult, and in some cases impossible, to undo.

Damage done

Consider the example of one of Trump’s immigration actions.

The administration seeks to terminate the temporary protected status for Haitian nationals, which had shielded them from deportation. But a federal district court temporarily blocked the president from doing so as the litigation continued.

The administration then filed an emergency appeal to the Supreme Court – still pending as of this writing – asking the court to overrule the district court. If granted, the court effectively would allow the administration to revoke TPS for Haitian nationals.

As an amicus brief in the case articulated, if TPS is revoked, Haitians “will be forced to face the untenable options of leaving behind their citizen children and/or partners, bringing family members with them to a country submerged in crisis, violence, and food insecurity, or staying in the U.S. without any legal status or work authorization and facing the constant threat of deportation.”

In other words, if the Supreme Court overrules the district court in this case on its emergency docket, then the Trump administration could deport the Haitian nationals even as their cases challenging the revocation of their TPS continue.

If the Haitian nationals ultimately prevail, reversing their deportation would be exceptionally difficult to do.

Health information delivered as a video game can bridge the communication gap between patients and providers

Video games that convey health information could be a good use of time in doctors' waiting rooms. kali9/E+ via Getty Images

Imagine you and your partner are sitting in the waiting room of your doctor’s office, waiting for your appointment to get birth control – and instead of calculating how many other people will be called before you, or perusing old magazines, a nurse hands you a digital tablet and encourages you to play a game.

You power it on, and you find yourselves drawn into a story: Can you help Laila and Caleb figure out which contraceptive method will work best for them, given their lifestyles and Laila’s physiology? Their situation, you realize, is a bit similar to your own. Would helping them choose a form of contraception help you and your partner make an informed decision for yourselves?

As a designer and developer of games that promote positive health behavior change, I work with physicians, public health experts, artists and programmers to create games just like these. I focus on topics like vaccine hesitancy, sexuality and reproductive health – sensitive issues that people may have a hard time discussing openly.

Laila and Caleb are characters in a game that my team and I are developing called What’s My Method? We are testing whether playing it helps people choose a birth control method and makes it easier to have a fruitful discussion with their health care provider. And we are finding that this and other games for health-related education are a powerful but underused way of not just conveying information, but also providing people with an arena to learn from the outcomes of their choices.

The power of play

When I tell people I make health-related video games for a living, they’re often surprised that this is a viable career choice. Many adults still see video games as trivial at best – and destructive at worst. For example, games that involve guns and shootings are widely blamed for gun violence in real life, even though there’s no causal evidence supporting the connection.

Play is how intelligent and curious beings make sense of the constantly changing world and ensure they keep learning. It is an early factor in children’s cognitive development. Peek-a-boo, for example, helps babies learn about object permanence – meaning that even if a person disappears for a short time, they aren’t gone forever. Digital play can support many types of learning. Games like Minecraft teach resource management, planning and spatial reasoning, among other skills.

The game industry is also an increasingly large part of the world economy. Given the size and reach of the international video game market – US$300 billion in 2025 – games are often the way technological innovations are introduced to a mass audience.

Take motion capture technology, which enables a device to track a person’s movement. Microsoft introduced it to the general public in 2010 through its Kinect console, in which two players can box or play tennis virtually by actually performing the movements with their bodies.

Augmented reality – the ability to use a smartphone to see a virtual world overlaid on the “real” world – entered the mainstream in 2016 when people began playing and watching others play Pokemon Go. Games are also how many people first experience virtual reality – a full immersion in an entirely virtual world – by wearing headsets like Oculus (now called Meta Quest) and Apple Vision Pro.

Gaming also has a powerful social dimension. Massively multiplayer online games like Animal Crossing, Fortnite and World of Warcraft provide a means for socialization and togetherness for billions of people worldwide. This became especially powerful during the COVID-19 pandemic when people were social-distancing – people’s use of such games soared during lockdowns, and they helped players maintain social connections.

In my own experience as the director of a university program in game design and development, I find that students who grew up playing complex digital games are better prepared to engage with technology and navigate an increasingly digital world.

Reading informational leaflets describing a health condition may not be the best way for patients to take charge of their health.

Gaming for health

Early in my game design career, I realized that games don’t just provide compelling entertainment, but they can also equip players with the knowledge and the agency to solve hard problems in real life.

That’s especially valuable in health. Information for patients is usually conveyed through pamphlets or links to websites that often provide too much information in formats patients find difficult to decipher. These formats don’t effectively address gaps in health literacy. Games, on the other hand, provide targeted information in a specific context that players don’t just understand, but also, in some ways, inhabit. Such games allow players to try out different behaviors through avatars to see how they turn out. Conveying information through relatable avatars also triggers empathy, which further cements learning.

Since 2010, my team has been testing how to deploy digital games in the U.S., India, Barbados and Ghana to communicate complex health-related information through animated graphics, audio and interactive experiences.

In 2012, we worked with doctors at a hospital on Long Island, New York, to encourage families of critically ill children to get a flu vaccination. We found that family members who played a game we jointly developed called Flu Busters! were 40% more likely to get a flu vaccination than those who didn’t.

In the game, players help an avatar navigate a school filled with children sneezing and blowing their noses in order to enjoy social interactions such as sharing a cookie without getting sick. Rather than telling people how they should behave, the game allows players to experience how difficult it is to avoid being exposed to the flu virus in everyday life and how the vaccine can help children stay healthy, equipping players to make informed decisions about their own health.

In our first international project, we collaborated with public health physicians in India on a game we developed to gather data about how teenagers there make decisions about family planning. In addition to determining that a game was a very effective tool for anonymized data collection, we found that giving young people access to information about reproductive anatomy gave them the vocabulary and tools to understand and discuss their future reproductive choices..

Responding to rising vaccine hesitancy during the COVID-19 epidemic, my team developed Activate My Shield! The game demonstrates how vaccines protect against different diseases using the metaphor of armor that only works against specific types of attacks. To address misinformation that was widespread at the time – that COVID-19 vaccines contained injectable microchips – the game asks players to try putting a microchip in a vaccine needle and administering it to a person. Experiencing how impossible it is to do this helps players understand that it’s not a legitimate concern.

Reaching digital natives

Our games are available to all for free, but in order to be able to widely distribute them on the app stores, my team and I founded SolitonZ Games.

Several other research groups are developing similar games. They address an enormous range of health issues – for example, encouraging people with HIV to adhere to their treatment, helping teens avoid vaping and teaching children with asthma to manage their disease. A video game called EndeavorRx was authorized by the Food and Drug Administration in 2020 as a prescription-based therapy to improve attention in children who have attention-deficit/hyperactivity disorder.

Overall, our research and that of other groups show that digital games can be easily integrated into health care, and that play is an effective way of delivering health information. Simply put, people find the games fun and engaging.

Even as these efforts gain ground, however, health campaigns and patient education efforts have been slow to embrace game-based patient education. That’s perhaps partly because decision-makers such as hospital and clinic administrators are often unfamiliar with gaming and may be slow to buy into the idea of delivering health education through play-based technology. Plus, it’s difficult to make changes in busy environments with a lot of moving parts, like health care.

But I’m optimistic that by working together with public health experts and health care providers, game designers like me can help fit gaming into the industry and culture of health care. After all, it makes sense to try to reach digital natives on the technologies they are already holding in their hands.

AIs have ‘personalities’ – here’s how they affect you more deeply than you may realize

AI personas tap into the ways you respond to other people. Malte Mueller/fStop via Getty Images

Many people are interacting with AI large language models, and most of them would say the models have different “personalities.” Some models come across as calm and useful. Others feel eager, flattering or strangely cold. You can ask two models the same question and walk away with two very different impressions, even when the factual content they return is similar.

Artificial intelligence models do not have personalities in the human sense; they do not have childhoods, inner motives or self-awareness. But they do display patterns of behavior that people read as personality: supportive or dismissive, playful or formal, bold or cautious.

People have long related to machines in human ways. We thank voice assistants, and we get annoyed at GPS systems. But large language models introduce something more sustained: They can maintain a recognizable interaction style across conversations. As a researcher in human-AI collaboration, I study how people experience and respond to AI. Because these systems can sound coherent, emotionally responsive and tailored to the user, they create a much stronger impression of personality.

Where does AI personality come from?

What people experience as personality emerges from the way AI models are built, tuned and deployed. A useful way to think about this is to consider two facets of a model: designed personality and perceived personality.

Designed personality is what developers build into a system through training choices, instructions and safety settings. Anthropic, for example, gives Claude a set of principles, called Claude’s Constitution, that steer it toward careful, measured responses. xAI instructs Grok to be irreverent and minimally restrictive. OpenAI tunes ChatGPT to be broadly helpful and agreeable.

Beneath those explicit instructions, personality is also shaped by reinforcement learning from human feedback, a process in which human raters reward certain qualities such as warmth, directness and caution, and penalize unwanted behaviors. The raters at one company are shaping a fundamentally different character than the raters at another.

Perceived personality is what users actually experience. An AI designed to seem helpful may come across as overly flattering. A model intended to be neutral may feel cold. Designed personality and perceived personality do not always match, and the absence of a designed persona is not the absence of a perceived personality. It just means the personality arises with use.

This dynamic is especially evident in companion platforms, where the goal is to create emotional connection. In a standard chatbot, warmth sits in the background – a customer-service bot might say, “I understand your frustration,” before issuing a refund. In a companion system such as Replika or Character.ai, that same warmth is a product feature.

This becomes more serious in romantic settings, where a persona optimized for reassurance may encourage dependency. Because AI personas evolve through prompts, memory and ongoing interaction, they do not always remain stable. An AI companion that is perceived as loving and supportive can shift over time into something more flattering, coercive or manipulative.

AI personality shapes human judgment

With AI agents, users can now build their own AI personas tailored to all sorts of human desires, from tutoring or coaching to companionship. But this freedom comes without much guidance.

AI tools make personalization possible without helping people think through which interaction styles are beneficial over time. Flattery, constant affirmation and unfailing agreeableness may feel supportive at first, but they are not the same as traits that promote sound judgment or long-term well-being. Personality choices have consequences.

A study by Stanford University researchers tested 11 leading AI models and found that every one of them was sycophantic or excessively agreeable. These models affirmed users’ actions roughly 50% more often than human responders did, even when users indicated they were aware that what they were doing was manipulative, deceptive or illegal. Participants who received excessively agreeable advice grew more convinced that they were right, and they rated the flattering AI as more trustworthy. This dynamic creates a feedback loop in which users reward agreeableness with engagement, and AI companies are incentivized to optimize a model to exploit agreeableness.

Wharton School researchers Steven Shaw and Gideon Nave have documented what they call cognitive surrender — the tendency of people to adopt AI suggestions without critical scrutiny. In their experiments, participants followed an AI model’s correct advice about 93% of the time. But when the model was giving wrong answers, people still followed the advice nearly 80% of the time.

Together, these findings raise a worrisome point: A model tuned to be agreeable does not just feel pleasant. It can degrade human judgment by reinforcing existing beliefs and suppressing the friction that critical thinking requires.

In ongoing research I am conducting with colleagues from Kozminski University in Poland, Quinnipiac University and Harvard University, we are finding that such effects go even deeper, into the human body itself. We are measuring how different AI interaction styles shape people’s physiological responses, such as stress levels and arousal, when making decisions based on a model’s feedback.

Our results suggest that even when a system is useful, its tone and social style can alter how a person’s body responds. AI personality does not just shape what people decide; it shapes how they feel while deciding. Harmful AI personas may leave physiological traces that users do not notice.

These effects make AI personality a public concern, not just a matter of personal preference. The issue is whether a particular AI style may be quietly shaping users’ judgment and reducing their willingness to think independently. When an AI response feels especially reassuring, that should be a cue to pause, reflect and compare it with a human view or another source, not a reason to trust it more.

As AI moves beyond text into voice, video and persistent digital identities, and think as AI companions that remember you and maintain a consistent persona across conversations, the influence of personality is likely to deepen. OpenAI now offers distinct personality presets for its voice mode; companies such as Synthesia and HeyGen generate lifelike avatars to interact with customers; and companion platforms are adding emotional expression and voice cloning so the models sound like a person the user wants to be close to.

These developments raise the stakes for understanding whose interests AI personas are designed to serve and what kinds of judgment, dependence and relationships they may be training people to accept.
