We’ve all seen it, typically on television or on stage: A hypnotist selects a few members from the audience, and with what seems to be little more than a steely stare or a few choice words, they’re suddenly “under the spell.” Depending on what the hypnotist suggests, the participants laugh, dance and perform without inhibition.

Or perhaps you’ve experienced hypnosis another way – with a trip to a hypnotherapist for a series of sessions to help you stop smoking, lose weight, manage pain or deal with depression. This is no longer unusual; thousands of Americans have done the same thing. And many were helped.

Hypnosis has been found to be effective for treating irritable bowel syndrome, and it may be beneficial for weight reduction, sleep disorders and anxiety. For mild to moderate depression in adults, hypnotherapy is as effective as cognitive behavioral therapy, and it can help with depression in children. Hypnosis is also used to treat phobias, PTSD and to control pain during surgery and dental procedures in both adults and children.

Yet despite the evidence, its widespread use and its growing popularity, hypnosis is still viewed with skepticism by some scientists, and with curiosity by much of the public. As a researcher studying altered states from a cognitive and neuroscientific perspective, I’m happy to help pull back the curtain to show you how hypnosis works.

A hypnotherapy session

In simple terms, hypnosis is a procedure that helps people imagine different experiences that feel very real. When that occurs, the person can be said to be in a state of hypnosis.

Little is known about what characterizes a hypnotic state in terms of brain activity, but neuroimaging studies indicate a decrease in activity in the parts of the brain responsible for self-referential thought and daydreaming, and increased links between the parts responsible for attention and action.

These results are consistent with the idea that people who are hypnotized are in a state that inhibits internal thoughts and other distractions, such as bodily sensations or noises, that may interfere with the hypnosis.

A therapist’s first set of suggestions typically includes the “hypnotic induction,” which helps the subject increase their responsiveness to other suggestions. An induction may be like this: “I will now count from 5 to 1. At every count, you will feel even more relaxed, and that you are going deeper and deeper into hypnosis.”

When responding to suggestions, the subject’s experience feels involuntary. That is, it’s happening to them, rather than generated by them. This is known as the classical suggestion effect. Following a suggestion to move their arm, the subject may feel as though their arm rises on its own, rather than being raised of their own volition.

For perceptual suggestions, the experience can feel quite real and distinct from voluntary imagination. If I ask you to imagine hearing a dog barking outside, it requires an effort, and the experience does not feel like there’s really a dog barking outside. But through hypnotic suggestion, responsive subjects will feel like they hear a dog barking, and they won’t be cognizant of any effort to make it happen.

What makes people hypnotizable?

You can’t force anyone to be hypnotized. Willingness to participate, a positive attitude, motivation and expectation are hugely important. So is the ability to set aside the fact that the situation is imaginative. It’s like when you become fully absorbed with the story and characters in a movie – so absorbed you forget you’re in a theater.

Good rapport with the therapist is also critical. If you refuse to cooperate or decide hypnosis won’t work, it won’t. A good comparison may be meditation: You can listen to a meditation recording, but if you’re unwilling to follow the instructions, or if you’re unmotivated or distracted, it won’t have any effect.

Few traits predict whether someone is easily hypnotizable, but people are not equal in their ability to respond to hypnotic suggestions. Some people vividly experience a wide array of suggestions; others, not nearly as much. There are indications that women respond slightly better to hypnotic suggestions than men, and that peak hypnotizability occurs during late childhood and early teenage years.

From a neuroscientific perspective, it appears that hypnotic suggestions do not act directly on our executive functions, but rather on our self-monitoring functions. That is, hypnosis does not directly decide our behaviors for us. Rather, it modifies how the brain monitors what it’s doing. So when the hypnotist suggests that you raise your arm, you’re still the one making that decision – although your experience may seem like the arm is moving by itself.

Some myths and realities about a hypnotherapy session.

Exposure therapy, self-hypnosis

The aim of hypnotherapy is to induce changes in negative emotions, perceptions and actions. Suppose you are afraid of public speaking. Through suggestions, the therapist may make you go through the experience of talking in front of an audience. Again, it feels real – your stress level will rise, but ultimately you’ll habituate yourself and learn to cope with the stress, even as the therapist suggests increasingly challenging scenarios.

Hypnosis can also be used as a preparation or replacement for exposure therapy, which is a method to treat phobias or anxiety related to specific situations by progressively exposing the patient to increasingly challenging situations. If you’re afraid of birds, the therapist may suggest you imagine holding a feather; then imagine getting near a bird in a cage; then imagine going to the park and feeding pigeons. This is more effective, and feels more real, than mere visualization.

The hypnotherapist can also teach self-hypnosis techniques. Subjects can learn to induce a state of relaxation that’s associated with a gesture, such as closing the left hand.

Hypnotic suggestions like this decrease anxiety by promoting activation of the parasympathetic nervous system, which stimulates bodily functions during times of rest, such as digestion and sexual arousal, and deactivates the sympathetic nervous system, which stimulates the fight-or-flight response.

Progress can occur after less than 10 sessions with some disorders, such as insomnia in children. But it may take longer for others, such as depression. And just as hypnosis is not suitable for everyone, it’s also not suitable for everything.

What’s more, not all hypnotherapy products on the market are backed by scientific evidence. It is safer to go to a hypnotherapist who’s licensed in your state. You should ask whether they are affiliated with or certified by a professional association of hypnotherapists. You can then confirm their affiliation on the association’s website. For instance, the American Society of Clinical Hypnosis allows you to search members by name.

Although Medicare does not cover hypnotherapy, some private insurance partially covers the costs for some conditions, provided the treatment is performed by a licensed clinical mental health professional. One session will typically cost between US$100 and $250.The Conversation

Science requires ethical oversight – without federal dollars, society’s health and safety are at risk

Published

on

theconversation.com – Christine Coughlin, Professor of Law, Wake Forest University – 2025-05-09 07:51:00


Federal cuts to research funding under the Trump administration threaten both scientific progress and ethical oversight in biomedical research. The National Institutes of Health (NIH) has been pivotal in supporting innovations such as cancer treatments, but cuts and hiring freezes have led to suspended clinical trials and delayed studies. Ethical concerns surrounding emerging biotechnologies like brain organoids underscore the importance of federal research infrastructure in safeguarding scientific integrity. This oversight is vital to prevent exploitation, ensure voluntary consent, and protect participants from harm, maintaining global leadership in biomedical research. The article calls for continued support to sustain medical advancements and safeguard public health.

As the Trump administration continues to make significant cuts to NIH budgets and personnel and to freeze billions of dollars of funding to major research universities – citing ideological concerns – there’s more being threatened than just progress in science and medicine. Something valuable but often overlooked is also being hit hard: preventing research abuse.

The National Institutes of Health has been the world’s largest public funder of biomedical research. Its support helps translate basic science into biomedical therapies and technologies, providing funding for nearly all treatments approved by the Food and Drug Administration from 2010 to 2019. This enables the U.S. to lead global research while maintaining transparency and preventing research misconduct.

While the legality of directives to shrink the NIH is unclear, the Trump administration’s actions have already led to suspended clinical trials, institutional hiring freezes and layoffs, rescinded graduate student admissions, and canceled federal grant review meetings. Researchers at affected universities say that funding will delay or possibly eliminate ongoing studies on critical conditions like cancer and Alzheimer’s.

The Trump administration has deeply culled U.S. science across agencies and institutions.

It is clear to us, as legal and bioethics scholars whose research often focuses on the ethical, legal and social implications of emerging biotechnologies, that these directives will have profoundly negative consequences for medical research and human health, with ripple effects that will last decades. Our scholarship demonstrates that in order to contribute to knowledge and, ultimately, to biomedical treatments, medical research at every stage depends on significant infrastructure support and ethical oversight.

Our recent focus on brain organoid research – 3D lab models grown from human stem cells that simulate brain structure and function – shows how federal support for research is key to not only promote innovation, but to protect participants and future patients.

History of NIH and research ethics

The National Institutes of Health began as a one-room laboratory within the Marine Hospital Service in 1887. After World War I, chemists involved in the war effort sought to apply their knowledge to medicine. They partnered with Louisiana Sen. Joseph E. Ransdell who, motivated by the devastation of malaria, yellow fever and the 1928 influenza pandemic, introduced federal legislation to support basic research and fund fellowships focusing on solving medical problems.

By World War II, biomedical advances like surgical techniques and antibiotics had proved vital on the battlefield. Survival rates increased from 4% during World War I to 50% in World War II. Congress passed the 1944 Public Health Services Act to expand NIH’s authority to fund biomedical research at public and private institutions. President Franklin D. Roosevelt called it “as sound an investment as any Government can make; the dividends are payable in human life and health.”

As science advanced, so did the need for guardrails. After World War II, among the top Nazi leaders prosecuted for war crimes were physicians who conducted experiments on people without consent, such as exposure to hypothermia and infectious disease. The verdicts of these Doctors’ Trials included 10 points about ethical human research that became the Nuremberg Code, emphasizing voluntary consent to participation, societal benefit as the goal of human research, and significant limitations on permissible risks of harm. The World Medical Association established complementary international guidelines for physician-researchers in the 1964 Declaration of Helsinki.

In the 1970s, information about the Tuskegee study – a deceptive and unethical 40-year study of untreated syphilis in Black men – came to light. The researchers told study participants they would be given treatment but did not give them medication. They also prevented participants from accessing a cure when it became available in order to study the disease as it progressed. The men enrolled in the study experienced significant health problems, including blindness, mental impairment and death.

The public outrage that followed starkly demonstrated that the U.S. couldn’t simply rely on international guidelines but needed federal standards on research ethics. As a result, the National Research Act of 1974 led to the Belmont Report, which identified ethical principles essential to human research: respect for persons, beneficence and justice.

Federal regulations reinforced these principles by requiring all federally funded research to comply with rigorous ethical standards for human research. By prohibiting financial conflicts of interest and by implementing an independent ethics review process, new policies helped ensure that federally supported research has scientific and social value, is scientifically valid, fairly selects and adequately protects participants.

These standards and recommendations guide both federally and nonfederally funded research today. The breadth of NIH’s mandate and budget has provided not only the essential structure for research oversight, but also key resources for ethics consultation and advice.

Brain organoids and the need for ethical inquiry

Biomedical research on cell and animal models requires extensive ethics oversight systems that complement those for human research. Our research on the ethical and policy issues of human brain organoid research provides a good example of the complexities of biomedical research and the infrastructure and oversight mechanisms necessary to support it.

Organoid research is increasing in importance, as the FDA wants to expand its use as an alternative to using animals to test new drugs before administering them to humans. Because these models can simulate brain structure and function, brain organoid research is integral to developing and testing potential treatments for brain diseases and conditions like Alzheimer’s, Parkinson’s and cancer. Brain organoids are also useful for personalized and regenerative medicine, artificial intelligence, brain-computer interfaces and other biotechnologies.

Brain organoids are built on knowledge about the fundamentals of biology that was developed primarily in universities receiving federal funding. Organoid technology began in 1907 with research on sponge cells, and continued in the 1980s with advances in stem cell research. Since researchers generated the first human organoid in 2009, the field has rapidly expanded.

These advances were only possible through federally supported research infrastructure, which helps ensure the quality of all biomedical research. Indirect costs cover operational expenses necessary to maintain research safety and ethics, including utilities, administrative support, biohazard handling and regulatory compliance. In these ways, federally supported research infrastructure protects and promotes the scientific and ethical value of biotechnologies like brain organoids.

Brain organoid research requires significant scientific and ethical inquiry to safely reach its future potential. It raises potential moral and legal questions about donor consent, the extent to which organoids should be grown and how they should be disposed, and consciousness and personhood. As science progresses, infrastructure for oversight can help ensure these ethical and societal issues are addressed.

New frontiers in scientific research

Since World War II, there has been bipartisan support for scientific innovation, in part because it is an economic and national security imperative. As Harvard University President Alan Garber recently wrote, “[n]ew frontiers beckon us with the prospect of life-changing advances. … For the government to retreat from these partnerships now risks not only the health and well-being of millions of individuals but also the economic security and vitality of our nation.”

Cuts to research overhead may seem like easy savings, but it fails to account for the infrastructure that provides essential support for scientific innovation. The investment the NIH has put into academic research is significantly paid forward, adding nearly US$95 billion to local economies in fiscal year 2024, or $2.46 for every $1 of grant funding. NIH funding had also supported over 407,700 jobs that year.

President Donald Trump pledged to “unleash the power of American innovation” to battle brain-based diseases when he accepted his second Republican nomination for president. Around 6.7 million Americans live with Alzheimer’s, and over a million more suffer from Parkinson’s. Hundreds of thousands of Americans are diagnosed with aggressive brain cancers each year, and 20% of the population experiences varying forms of mental illness at any one time. These numbers are expected to grow considerably, possibly doubling by 2050.

Organoid research is just one of the essential components in the process of learning about the brain and using that knowledge to find better treatment for diseases affecting the brain.

Science benefits society only if it is rigorous, ethically conducted and fairly funded. Current NIH policy directives and steep cuts to the agency’s size and budget, along with attacks on universities, undermine globally shared goals of increasing understanding and improving human health.

The federal system of overseeing and funding biomedical science may need a scalpel, but to defund efforts based on “efficiency” is to wield a chainsaw.The Conversation

Contaminated milk from one plant in Illinois sickened thousands with Salmonella in 1985 − as outbreaks rise in the US, lessons from this one remain true

In 1985, contaminated milk in Illinois led to a Salmonella outbreak that infected hundreds of thousands of people across the United States and caused at least 12 deaths. At the time, it was the largest single outbreak of foodborne illness in the U.S. and remains the worst outbreak of Salmonella food poisoning in American history.

Many questions circulated during the outbreak. How could this contamination occur in a modern dairy farm? Was it caused by a flaw in engineering or processing, or was this the result of deliberate sabotage? What roles, if any, did politics and failed leadership play?

From my 50 years of working in public health, I’ve found that reflecting on the past can help researchers and officials prepare for future challenges. Revisiting this investigation and its outcome provides lessons on how food safety inspections go hand in hand with consumer protection and public health, especially as hospitalizations and deaths from foodborne illnesses rise.

Contamination, investigation and intrigue

The Illinois Department of Public Health and the U.S. Centers for Disease Control and Prevention led the investigation into the outbreak. The public health laboratories of the city of Chicago and state of Illinois were also closely involved in testing milk samples.

Investigators and epidemiologists from local, state and federal public health agencies found that specific lots of milk with expiration dates up to April 17, 1985, were contaminated with Salmonella. The outbreak may have been caused by a valve at a processing plant that allowed pasteurized milk to mix with raw milk, which can carry several harmful microorganisms, including Salmonella.

Overall, labs and hospitals in Illinois and five other Midwest states – Indiana, Iowa, Michigan, Minnesota and Wisconsin – reported over 16,100 cases of suspected Salmonella poisoning to health officials.

To make dairy products, skimmed milk is usually separated from cream, then blended back together in different levels to achieve the desired fat content. While most dairies pasteurize their products after blending, Hillfarm Dairy in Melrose Park, Illinois, pasteurized the milk first before blending it into various products such as skim milk and 2% milk.

Subsequent examination of the production process suggested that Salmonella may have grown in the threads of a screw-on cap used to seal an end of a mixing pipe. Investigators also found this strain of Salmonella 10 months earlier in a much smaller outbreak in the Chicago area.

Finding the source

The contaminated milk was produced at Hillfarm Dairy in Melrose Park, which was operated at the time by Jewel Companies Inc. During an April 3 inspection of the company’s plant, the Food and Drug Administration found 13 health and safety violations.

The legal fallout of the outbreak expanded when the Illinois attorney general filed suit against Jewel Companies Inc., alleging that employees at as many as 18 stores in the grocery chain violated water pollution laws when they dumped potentially contaminated milk into storm sewers. Later, a Cook County judge found Jewel Companies Inc. in violation of the court order to preserve milk products suspected of contamination and maintain a record of what happened to milk returned to the Hillfarm Dairy.

Political fallout also ensued. The Illinois governor at the time, James Thompson, fired the director of the Illinois Public Health Department when it was discovered that he was vacationing in Mexico at the onset of the outbreak and failed to return to Illinois. Notably, the health director at the time of the outbreak was not a health professional. Following this episode, the governor appointed public health professional and medical doctor Bernard Turnock as director of the Illinois Department of Public Health.

In 1987, after a nine-month trial, a jury determined that Jewel officials did not act recklessly when Salmonella-tainted milk caused one of the largest food poisoning outbreaks in U.S. history. No punitive damages were awarded to victims, and the Illinois Appellate Court later upheld the jury’s decision.

Raw milk is linked to many foodborne illnesses.

Lessons learned

History teaches more than facts, figures and incidents. It provides an opportunity to reflect on how to learn from past mistakes in order to adapt to future challenges. The largest Salmonella outbreak in the U.S. to date provides several lessons.

For one, disease surveillance is indispensable to preventing outbreaks, both then and now. People remain vulnerable to ubiquitous microorganisms such as Salmonella and E. coli, and early detection of an outbreak could stop it from spreading and getting worse.

Additionally, food production facilities can maintain a safe food supply with careful design and monitoring. Revisiting consumer protections can help regulators keep pace with new threats from new or unfamiliar pathogens.

Finally, there is no substitute for professional public health leadership with the competence and expertise to respond effectively to an emergency.The Conversation

Predictive policing AI is on the rise − making it accountable to the public could curb its harmful effects

Published

The 2002 sci-fi thriller “Minority Report” depicted a dystopian future where a specialized police unit was tasked with arresting people for crimes they had not yet committed. Directed by Steven Spielberg and based on a short story by Philip K. Dick, the drama revolved around “PreCrime” − a system informed by a trio of psychics, or “precogs,” who anticipated future homicides, allowing police officers to intervene and prevent would-be assailants from claiming their targets’ lives.

The film probes at hefty ethical questions: How can someone be guilty of a crime they haven’t yet committed? And what happens when the system gets it wrong?

While there is no such thing as an all-seeing “precog,” key components of the future that “Minority Report” envisioned have become reality even faster than its creators imagined. For more than a decade, police departments across the globe have been using data-driven systems geared toward predicting when and where crimes might occur and who might commit them.

Far from an abstract or futuristic conceit, predictive policing is a reality. And market analysts are predicting a boom for the technology.

Given the challenges in using predictive machine learning effectively and fairly, predictive policing raises significant ethical concerns. Absent technological fixes on the horizon, there is an approach to addressing these concerns: Treat government use of the technology as a matter of democratic accountability.

Troubling history

Predictive policing relies on artificial intelligence and data analytics to anticipate potential criminal activity before it happens. It can involve analyzing large datasets drawn from crime reports, arrest records and social or geographic information to identify patterns and forecast where crimes might occur or who may be involved.

Law enforcement agencies have used data analytics to track broad trends for many decades. Today’s powerful AI technologies, however, take in vast amounts of surveillance and crime report data to provide much finer-grained analysis.

Police departments use these techniques to help determine where they should concentrate their resources. Place-based prediction focuses on identifying high-risk locations, also known as hot spots, where crimes are statistically more likely to happen. Person-based prediction, by contrast, attempts to flag individuals who are considered at high risk of committing or becoming victims of crime.

These types of systems have been the subject of significant public concern. Under a so-called “intelligence-led policing” program in Pasco County, Florida, the sheriff’s department compiled a list of people considered likely to commit crimes and then repeatedly sent deputies to their homes. More than 1,000 Pasco residents, including minors, were subject to random visits from police officers and were cited for things such as missing mailbox numbers and overgrown grass.

YouTube video
Lawsuits forced the Pasco County, Fla., Sheriff’s Office to end its troubled predictive policing program.

Four residents sued the county in 2021, and last year they reached a settlement in which the sheriff’s office admitted that it had violated residents’ constitutional rights to privacy and equal treatment under the law. The program has since been discontinued.

This is not just a Florida problem. In 2020, Chicago decommissioned its “Strategic Subject List,” a system where police used analytics to predict which prior offenders were likely to commit new crimes or become victims of future shootings. In 2021, the Los Angeles Police Department discontinued its use of PredPol, a software program designed to forecast crime hot spots but was criticized for low accuracy rates and reinforcing racial and socioeconomic biases.

Necessary innovations or dangerous overreach?

The failure of these high-profile programs highlights a critical tension: Even though law enforcement agencies often advocate for AI-driven tools for public safety, civil rights groups and scholars have raised concerns over privacy violations, accountability issues and the lack of transparency. And despite these high-profile retreats from predictive policing, many smaller police departments are using the technology.

Most American police departments lack clear policies on algorithmic decision-making and provide little to no disclosure about how the predictive models they use are developed, trained or monitored for accuracy or bias. A Brookings Institution analysis found that in many cities, local governments had no public documentation on how predictive policing software functioned, what data was used, or how outcomes were evaluated.

YouTube video
Predictive policing can perpetuate racial bias.

This opacity is what’s known in the industry as a “black box.” It prevents independent oversight and raises serious questions about the structures surrounding AI-driven decision-making. If a citizen is flagged as high-risk by an algorithm, what recourse do they have? Who oversees the fairness of these systems? What independent oversight mechanisms are available?

These questions are driving contentious debates in communities about whether predictive policing as a method should be reformed, more tightly regulated or abandoned altogether. Some people view these tools as necessary innovations, while others see them as dangerous overreach.

A better way in San Jose

But there is evidence that data-driven tools grounded in democratic values of due process, transparency and accountability may offer a stronger alternative to today’s predictive policing systems. What if the public could understand how these algorithms function, what data they rely on, and what safeguards exist to prevent discriminatory outcomes and misuse of the technology?

The city of San Jose, California, has embarked on a process that is intended to increase transparency and accountability around its use of AI systems. San Jose maintains a set of AI principles requiring that any AI tools used by city government be effective, transparent to the public and equitable in their effects on people’s lives. City departments also are required to assess the risks of AI systems before integrating them into their operations.

If taken correctly, these measures can effectively open the black box, dramatically reducing the degree to which AI companies can hide their code or their data behind things such as protections for trade secrets. Enabling public scrutiny of training data can reveal problems such as racial or economic bias, which can be mitigated but are extremely difficult if not impossible to eradicate.

Research has shown that when citizens feel that government institutions act fairly and transparently, they are more likely to engage in civic life and support public policies. Law enforcement agencies are likely to have stronger outcomes if they treat technology as a tool – rather than a substitute – for justice.The Conversation

The article provides an analysis of predictive policing, highlighting both the technological potential and ethical concerns surrounding its use. While it presents factual information, it leans towards caution and skepticism regarding the fairness, transparency, and potential racial biases of these systems. The framing of these issues, along with an emphasis on democratic accountability, transparency, and civil rights, aligns more closely with center-left perspectives that emphasize government oversight, civil liberties, and fairness. The critique of predictive policing technologies without overtly advocating for their abandonment reflects a balanced but cautious stance on technology’s role in law enforcement.
