For Quicker Cures, Do Not Cancel Those Who See What We Do Not See

Dogs smell odors that we do not smell. They say Eskimos can distinguish 40 or more kinds of snow. Physical differences in biology and differences in past experiences allow some people to perceive what other people miss. We should encourage, not cancel, those who see differently. They can communicate and act on what they see, giving us more cures more quickly.

In the passages quoted below, a case is made that Pasteur’s artistic experiences allowed him to see a structural difference (chirality) in crystals; a difference that turns out to matter for medical drug molecules.

(p. D5) In a paper published last month in Nature Chemistry, Dr. Gal explains how a young Pasteur fought against the odds to articulate the existence of chirality, or the way that some molecules exist in mirror-image forms capable of producing very different effects. Today we see chirality’s effects in light, in chemistry and in the body — even in the drugs we take.

And we might not know a thing about them if it weren’t for the little-known artistic experience of Louis Pasteur, says Dr. Gal.

. . .

As a teenager, Pasteur made portraits of his friends, family and dignitaries. But after his father urged him to pursue a more serious profession — one that would feed him — he became a scientist. At the age of 24 he discovered chirality.

To understand chirality, consider two objects held up before a mirror: a white cue ball from a pool table and your hand. The reflection of the ball is exactly like the original. If you could reach into that mirror, pull out the reflection and cram it inside the original, they’d match up point for point. But if you tried the same thing with your hand, no matter how much you tried, the mirror image would never fit into the original.

At the molecular level some objects are like cue balls, and they are always superimposable. But other things are like hands, and they can never be combined.

. . .

During winemaking, a chemical called tartaric acid builds up on vat walls. In the 18th and 19th centuries, makers of medicine and dyes used this acid.

In 1819, factory workers boiled wine too long and accidentally produced paratartaric acid, which had unique properties that intrigued scientists like Pasteur.

. . .

When studying the paratartaric acid, Pasteur found that it produced two kinds of crystals — one like those found in tartaric acid and another that was the mirror opposite. The crystals were handed, or what the Greeks call chiral (kheir) for hand.

. . .

“Several famous or much more accomplished scientists, some well along their illustrious careers, studied the same molecules, the same substances,” said Dr. Gal. “Realistically you would think they’d have beaten him to the punch, and yet they missed it.”

So why did this young, inexperienced chemist get it right?

Dr. Gal thinks the answer might lie in the artistic passions of Pasteur’s youth. Even as a scientist, Pasteur remained closely connected to art. He taught classes on how chemistry could be used in fine art and attended salons. He even carried around a notebook, jotting down 1-4 ratings of artwork he visited.

And then Dr. Gal stumbled upon a letter Pasteur had written to his parents about a lithographic portrait he had made of a friend.

Lithography back then involved etching a drawing onto a limestone slab with wax or oil and acid, and pressing a white piece of paper on top of it. The resulting picture was transposed, like a mirror image of the drawing left on the slab.

In his letter, Pasteur wrote:

“I think I have not previously produced anything as well drawn and having as good a resemblance. All who have seen it find it striking. But I greatly fear one thing, that is, that on the paper the portrait will not be as good as on the stone; this is what always happens.”

Eureka. “Isn’t this the explanation of how he saw the handedness on the crystals — because he was sensitized to that as an artist?” Dr. Gal proposed.

. . .

We now know that many drugs contain molecules that exist in two chiral forms, and that the two forms can react differently in the body. The most tragic example occurred in the 1950s and ’60s, when doctors prescribed Thalidomide, a drug for morning sickness and other ailments, to pregnant women. The drug also contained a chiral molecule that caused disastrous side effects in many babies.

Ozempic 25 Years Sooner Would Have Saved and Improved Many Lives

Apparently Ozempic had been discovered in the late 1980s and could have been on the market roughly 25 years ago. Pfizer decided that the likely potential revenues were not sufficient to justify the huge costs. But what if the costs had not been so huge? For instance what if we adopted the proposal suggested by Milton Friedman, and advocated by me, to stop mandating hyper-expensive Phase 3 clinical trials to prove efficacy? (The mandates to prove safety through Phase 1 and Phase 2 trials would be retained.) With lower costs, Pfizer might have moved forward. Or if Pfizer had not, some other firm probably would have entered the breach sooner. If Ozempic had been available sooner, by now it would be much cheaper. Many lives would have been saved that have been lost. Other lives would have been healthier and happier.

(p. A26) They called 2023 the year of Ozempic, but it now seems GLP-1 drugs might define an entire decade — or an even longer era. The game-changing drugs, which mimic the hormone GLP-1, offer large benefits for not just diabetes management and especially weight loss but also, apparently, heart and kidney and liver disease, Alzheimer’s and dementia, Parkinson’s and addiction of all kinds. And perhaps because of widespread use of the drugs, the obesity epidemic in America may finally and mercifully be reversing.

But of all the things we learned this year about GLP-1s, the most astonishing could be that the revolution might have started decades earlier. Researchers identified the key breakthrough for GLP-1 drugs nearly 40 years ago, it turns out, long before most Americans had even heard the phrase “obesity epidemic.”

This summer, a former dean of Harvard Medical School, Jeffrey Flier, published a long personal reflection that doubled as an alternate history of what may well be the most spectacular and impactful medical breakthrough of the century so far. In 1987, Flier co-founded a biotech start-up that pursued GLP-1 as a potential treatment for diabetes, not long after it had first been identified by researchers who’d also found that the hormone enhanced insulin secretion in the presence of glucose.

The startup obtained worldwide rights to develop GLP-1 as a metabolic therapy from a group of those researchers, based at Massachusetts General Hospital. They even generated clinical results that suggested it might have promise as a weight-loss drug as well — only to have Pfizer, which had agreed to fund the research, withdraw its support, without providing the researchers with an especially satisfying explanation. Instead, Pfizer told Flier and his partners that the company didn’t believe there would be a market for another injectable diabetes treatment after insulin. Well, Flier tells me, “they were wrong.”

. . .

. . . Flier’s memoir is not just a lament for what might have been. In the aftermath of the pandemic emergency, as citizens and officials alike have embraced a more libertarian attitude toward public health, there’s been a similar drift in the public conversation about drug discovery and development. Operation Warp Speed is often held up as a new model — calls for an Operation Warp Speed 2.0 have been followed by those for an Operation Warp Speed for everything — . . .

Many of the same reformers will complain about all the red tape at the F.D.A. and C.D.C., tallying up huge mortality costs imposed by slow-moving government, arguing for human challenge trials in which individuals volunteer to take untested drugs and be deliberately infected and even talking about the invisible graveyard of unnecessary regulation and delay.

This is all fine and good — there are surely lots of things those agencies can speed up. And in recent years, reformers of various stripes have lobbied some worthy additional proposals into the biomedical zeitgeist — for a system based not on patents but on huge and direct cash prizes for medical breakthroughs, for instance, or one helped along by advance market commitments or benevolent patent extensions. Just last week the researchers Willy Chertman and Ruxandra Tesloianu published “The Case for Clinical Trial Abundance,” an invigorating manifesto for drug development reform.

. . . in focusing on government bureaucracy as the major biomedical bottleneck, we are seeing just one piece of the picture and overlooking what is perhaps the central challenge of research and development — that it is, at present, so complicated that difficulties or bad decisions at any stage can stifle the whole decades-long process, distorting the actual medical and public-health functions of drug development in countless ways.

Reductio ad Absurdum: When a Functional MRI Showed Activity in a Dead Salmon’s Brain

I have long thought that most college students would benefit from a course in practical reasoning. One topic in such a course would be to define and illustrate the Reductio ad Absurdum argument. The argument starts with a proposition, and then infers an absurdity from the proposition, thereby refuting the original proposition. The review quoted below mentions such an argument that implicitly starts with the proposition that fMRI scans are reliable guides to human thought. The absurdity is that fMRI scans sometimes light up in the presence of a dead Atlantic salmon, which would seem to suggest that the salmon is thinking. The conclusion: be careful what you infer from fMRI scans.

My favorite reductio ad absurdum argument starts with the proposition that all actionable knowledge must derive from randomized double-blind clinical trials (RCTs). The argument then shows that no RCTs have been performed to show the efficacy of parachutes. The absurdity is that before anyone uses a parachute when exiting a flying airplane, he must first find an RCT to prove the efficacy of parachutes. The conclusion: when you volunteer for the first such RCT, hope that you are not assigned to the control group!

(p. A15) In 2009 a group of researchers placed a dead salmon in a functional magnetic resonance imaging (fMRI) scanner and showed the fish some photos of people in social situations. Their results, presented under the title “Neural Correlates of Interspecies Perspective Taking in the Post-Mortem Atlantic Salmon,” were surprising. The scans revealed a red spot of activity centered in the salmon’s brain.

The authors of the study weren’t trying to pull a fast one on the scientific community. Nor did they believe in zombie fish. They were showing that statistics, used incorrectly, can demonstrate almost anything. Specifically, a certain type of data analysis, often used on fMRI scans, can find signal where there should be only noise.

Russell Poldrack, a psychologist at Stanford University, mentions the stunt in “The New Mind Readers: What Neuroimaging Can and Cannot Reveal About Our Thoughts.” His book, ostensibly about fMRI and its use in studying how the brain functions (hence “functional”), serves as a lesson in how the science works—or should work. Through blunders and baloney, innovation and self-correction, the young field of cognitive neuroscience is quickly evolving.

To Kill a Dam, Environmentalist “Scientists” Lied About the Existence of the So-Called “Snail Darter”

In the 1970s the building of a dam in Tennessee was delayed because environmentalists claimed that its construction would threaten the extinction of a small fish they called the “snail darter.” Now fish biologists have established that there is no snail darter. The fish previously identified as a “snail darter” has the DNA of a small fish called a “stargazing darter” which was not, and is not, endangered.

A co-author of a new study says that this was no innocent mistake.

Dr. Near, . . . a professor who leads a fish biology lab at Yale, and his colleagues report in the journal Current Biology that the snail darter, Percina tanasi, is neither a distinct species nor a subspecies. Rather, it is an eastern population of Percina uranidea, known also as the stargazing darter, which is not considered endangered.

Dr. Near contends that early researchers “squinted their eyes a bit” when describing the fish, because it represented a way to fight the Tennessee Valley Authority’s plan to build the Tellico Dam on the Little Tennessee River, about 20 miles southwest of Knoxville.

“I feel it was the first and probably the most famous example of what I would call the ‘conservation species concept,’ where people are going to decide a species should be distinct because it will have a downstream conservation implication,” Dr. Near said.

In other words environmentalist “scientists” deliberately lied in order to promote their political agenda of cutting energy production.

In 2023, Costs of Medical Care Rose 40% Faster Than Overall Inflation

If rising healthcare costs were clearly due to improving health outcomes, few would be angry. The anger arises from rising fraud, inefficiency, and inertia. Many healthcare workers are paper pushers and the paper pushed is often inaccurate and opaque. Other healthcare workers enforce protocols that slow innovation. And of course mandated regulations, most notably Phase 3 clinical trials, enormously increase costs.

(p. A3) The killing of a health insurance executive in New York City prompted a furious outpouring of anger over the industry and healthcare prices. So just how much have healthcare costs and spending been going up?

The short answer: a lot. National healthcare spending increased 7.5% year over year in 2023 to $4.867 trillion, or $14,570 per person, according to data released Wednesday by the Centers for Medicare and Medicaid Services.

. . .

The 7.5% rise represented a much faster pace of growth than the 4.6% increase in 2022.

. . .

Over the past couple of decades, the price index for what the Labor Department classifies as medical care—which includes visits to doctors, hospital stays, prescription drugs and medical equipment—has risen roughly 40% faster than the overall pace of inflation. Healthcare tends to rise more quickly than overall inflation because of high labor costs in the sector, as well as advancements leading to new and more expensive drugs and treatments. Demand for healthcare is also increasing as the population ages.

. . .

Hospitals are . . . adding billions of dollars in “facility fees” to medical bills for routine care at outpatient centers, according to reporting by The Wall Street Journal. That means patients are often paying hundreds of additional dollars for standard care like colonoscopies, mammograms and heart screenings.

. . .

Employers are shouldering a lot of those costs. For example, the average worker spent $6,296 in premiums for family coverage in 2024, according to KFF [a healthcare nonprofit]. Employers spent $19,276.

But when a company is paying more for insurance premiums for its workers, that leaves it with less money for giving out raises or reinvesting and expansion.

“It’s ultimately all of us who pay for [healthcare] either in the form of lower wages for people who have employer insurance or in the form of higher taxes to cover Medicare and Medicaid,” said Katherine Baicker, professor of health economics at the University of Chicago.

Higher Fluoride in Water Correlated with Lower I.Q. in Children

When I was young, in the 1960s, I remember my family opposing the government fluoridation of the South Bend, Indiana water supply, even though our dentist, Dr. Stan Severyn, who we liked and respected, was in favor of fluoridating South Bend water. We thought that when consumed in water, fluoride was a cumulative poison, and we thought the dental benefits of fluoride could be obtained through applying fluoride directly to the teeth (as Dr. Severyn did to my teeth) or through the careful use of fluoridated toothpaste.

My memory is that the South Bend city council overwhelmingly approved adding fluoride to the city waster. My family was in a small minority and our views were widely dismissed. But small minorities are not always wrong. See The New York Times article quoted below. Or see the history of medicine more broadly, for instance when Ignaz Semmelweis was in a small minority suggesting that physicians returning from dissections in the morgue should wash their hands before delivering babies.

When our daughter Jenny was very young, I read that very young children often accidentally swallow toothpaste when they start brushing their own teeth. Then, as now, almost all toothpaste contained fluoride. So when Jenny reached the age of brushing I searched the shelves of several Omaha stores seeking non-fluoridated toothpaste. I finally found a couple of tubes, imported from Sweden I think, in a now defunct store called The Drug Emporium. Jenny used that toothpaste until she was old enough to reliably spit out the toothpaste after brushing.

[In the passages quoted below, “JAMA” stands for The Journal of the American Medical Association which, along with The New England Journal of Medicine and The Lancet, is widely considered to be one of the handful of top medical journals in the world. JAMA Pediatrics is one of several JAMA-associated field journals.]

(p. 19) Water fluoridation is widely seen as one of the great public health achievements of the 20th century, credited with substantially reducing tooth decay. But there has been growing controversy among scientists about whether fluoride may be linked to lower I.Q. scores in children.

A comprehensive federal analysis of scores of previous studies, published this week in JAMA Pediatrics, has added to those concerns. It found a significant inverse relationship between exposure levels and cognitive function in children.

Higher fluoride exposures were linked to lower I.Q. scores, concluded researchers working for the National Institute of Environmental Health Sciences.

. . .

The subject is so divisive that JAMA Pediatrics commissioned two editorials with opposing viewpoints to publish alongside the report.

In one, Dr. Steven M. Levy, a public health dentist at the University of Iowa, said that many of the studies included in the analysis were of very low quality.

. . .

In a second editorial published alongside the new study, a public health expert, Dr. Bruce P. Lanphear, noted that as far back as 1944, the editor of The Journal of the American Dental Association expressed concern about adding fluoride, which he termed “a highly toxic substance,” to drinking water. He wrote that “the potentialities for harm far outweigh those for good.”

Some studies have suggested that dental health has improved not because fluoride was added to water, but because of fluoridated toothpastes and better dental hygiene practices.

. . .

Some 74 studies from 10 countries, including China, Mexico, Canada, India and Denmark, were examined. Dr. Lanphear noted that the consistent links between fluoride and I.Q. were found in very different populations.

He urged the U.S. Public Health Service to set up a committee, perhaps one that does not include researchers who have studied the subject in the past and can take a fresh look at the topic, to examine two questions seriously: whether fluoride is neurotoxic, and whether it is as beneficial for oral health as it is believed to be.

“If that doesn’t happen urgently, my concern is there will be growing distrust of public health agencies amid the public, and they will have deserved it,” he said.

During the Covid Pandemic, “Public Health Officials Could Not Be Trusted to Tell the Whole Truth”

From the review quoted below, Rivers’s book is refreshingly open about the downsides of public health actions against epidemics. But in the end, I infer that Rivers still gives pride of place to public health actions in fighting epidemics. She wants public health actions to be reformed but believes that public health officials will be and should be the dominant actors during epidemics. I, to the contrary, believe that innovative medical entrepreneurs will be and should be the dominant actors. I believe that partly because medical entrepreneurship respects human liberty, while public health official commands do not respect human liberty, but also partly because medical entrepreneurship is more effective at ending epidemics.

(p. A15) As recently as 2019, confides Caitlin Rivers, an epidemiologist at Johns Hopkins, “I was confident that we knew how to navigate, if not control, a pandemic.” But within a year “that hubris was laid bare.” Covid-19 “overran us,” leaving in its wake a striking loss of confidence in public health.

“Crisis Averted” is Ms. Rivers’s ambitious and, given its charge, surprisingly successful attempt to reset our relationship with the field of public health. With a judicious blend of candor, hopefulness and pragmatism, she calls out its mistakes, reminds us of its historic accomplishments and emphasizes the need for the discipline to adjust its strategies if its full promise is to be realized.

. . .

. . . for every public-health triumph there are heartbreaking disappointments. In 2010, a lack of clean water and adequate sanitation allowed a cholera epidemic to rampage through Haiti after a catastrophic earthquake; worse, the disease, not endemic in the region, arrived through foreign aid workers. Human error was also responsible for the last recorded smallpox fatality, a medical photographer in the U.K. who died after the virus leaked from a sloppy lab on the floor below.

. . .

Animating much of Ms. Rivers’s narrative and analysis is the Covid-19 pandemic, a crisis that, as she laments, wasn’t averted.  . . .  She . . . describes early advice from public-health officials claiming that mask use was “not recommended” and “should be avoided” as “odd and brittle assertions that did not hold up to the slightest scrutiny” and left many with the impression that “public health officials could not be trusted to tell the whole truth.”

. . .

After years of relentless insistence that we “follow the science,” it’s refreshing to hear an expert illuminate all that remains unknown—from the vagaries of the common cold to the vexing challenge of coaxing healthy behavior change. Most epidemics of the past century, Ms. Rivers points out, “took forms that were slightly off-center from what epidemiologists expected”—the recent pandemic, for example, was caused not by an influenza virus, as anticipated, but rather by a coronavirus. Her advice: Expect a surprise.

Welcome Immigrant Innovators

Empirical research by reputable economists at some top schools concludes that although “immigrants represent 16 percent of all US inventors . . . immigrants are responsible for 36% of aggregate innovation, two-thirds of which is due to their innovation externalities on their native-born collaborators” (Bernstein et al. 2022, p. 1). (I have not yet looked carefully at this research, but have looked at other papers by Rebecca Diamond (no relation), finding them important and well-done.)

We should make it easier for innovators to enter the United States and harder for murderers and thieves to enter. And whatever immigration rules we adopt, we should enforce. We are unfair to those who follow our immigration rules if we allow others to enter the United States without following our rules.

Beyond that, I think our rules can be fairly generous, even letting in many non-innovative immigrants, if at the same time we adopt policies that give a probable path forward to current Americans who are among the least well-off. In a working paper that I hope to return to soon, I argue that we can create this path forward by unbinding entrepreneurs so that they can create more and better jobs for the least well-off.

Medicare “Advantage” Health Insurers (Especially UnitedHealth) Pressure Doctors to Recode Patients as Having Bogus, but Lucrative, Health Problems

The “advantage” in Medicare “Advantage” health insurance plans accrues to health insurance companies, not to patients or taxpayers. In an earlier entry I discussed an earlier Wall Street Journal article documenting how health insurers (especially UnitedHealth) sent nurses to patients’ homes for the purpose of harvesting diagnoses that would add to the health insurers’ payments. In an even earlier entry I discussed a Wall Street Journal article documenting how UnitedHealth has used vertical integration to game the system of Medicare “Advantage.”

(p. A1) Like most doctors, Nicholas Jones prefers to diagnose patients after examining them. When he worked for UnitedHealth Group, though, the company frequently prepared him a checklist of potential diagnoses before he ever laid eyes on them.

UnitedHealth only did that with the Eugene, Ore., family physician’s Medicare Advantage recipients, he said, and its software wouldn’t let him move on to his next patient until he weighed in on each diagnosis.

The diagnoses were often irrelevant or wrong, Jones said. UnitedHealth sometimes suggested a hormonal condition, secondary hyperaldosteronism, that was so obscure Jones had to turn to Google for help. “I needed to look it up,” he said.

The government’s Medicare Advantage system, which uses private insurers to provide health benefits to seniors and disabled people, pays the companies based on how sick patients are, to cover the higher costs of sicker patients. Medicare calculates sickness scores from information supplied by doctors and submitted by the insurers. In the case of UnitedHealth, many of those doctors work directly for UnitedHealth.

More diagnoses make for higher scores—and larger payments. A Wall Street Journal analysis found sickness scores increased when patients moved from traditional Medicare to Medicare Advantage, leading to billions of dollars in extra government payments to insurers.

Patients examined by doctors working for UnitedHealth, an industry pioneer in directly employing large numbers of physicians, had some of the biggest increases in sickness scores after moving (p. A8) from traditional Medicare to the company’s plans, according to the Journal’s analysis of Medicare data between 2019 and 2022.

Sickness scores for those UnitedHealth patients increased 55%, on average, in their first year in the plans, the analysis showed. That increase was roughly equivalent to every patient getting newly diagnosed with HIV, the virus that causes AIDS, and breast cancer, the analysis showed.

That far outpaced the 7% year-over-year rise in the sickness scores of patients who stayed in traditional Medicare, according to the analysis. Across Medicare Advantage plans run by all insurers, including UnitedHealth, scores for all newly enrolled patients rose by 30% in the first year.

. . .

In a series of articles this year [2024], the Journal has examined the practices of Medicare Advantage companies, including UnitedHealth, the largest. Among other things, the articles showed how diagnoses added by insurers increased payments from the government.

. . .

Jones, the Oregon doctor, said UnitedHealth didn’t suggest diagnoses for patients he treated outside Medicare Advantage, where it doesn’t pay.

Traditional Medicare patients treated by UnitedHealth doctors had much lower sickness scores, the Journal’s analysis showed.

A case of hyperaldosteronism—the obscure hormonal condition that sometimes appeared on Jones’s checklists—could trigger about $2,000 a year in Medicare Advantage payments during the period the Journal studied. The Journal’s analysis showed that doctors who didn’t work for UnitedHealth seldom diagnosed that condition, which involves elevated levels of a hormone linked to high blood pressure.

. . .

“The system is not primarily about taking care of the patient,” said Dr. Emilie Scott, who worked for a UnitedHealth-owned practice in California before leaving in 2016. “It’s, how do you get the money to flow?”

The Journal analysis is based on billions of Medicare records obtained under a research agreement with the federal government. The Journal also examined internal documents from medical practices owned by or under contract with UnitedHealth.

. . .

When Dr. Naysha Isom started working at a UnitedHealth medical group in the Las Vegas area in 2019, she said, she got two days of training on how to record diagnoses. At the training, a UnitedHealth employee suggested that Isom, who had practiced for more than a decade, should consider diagnoses she had never made before.

Isom said she was told that signs of bruising could be recorded as senile purpura, a condition that generated payments in Medicare Advantage but generally didn’t require treatment. Isom saw no point, since the finding didn’t change patients’ care: “OK, wear some sunscreen. Maybe stop bumping the wall.”

After she decided not to diagnose peripheral artery disease, a narrowing of blood vessels, based on a screening test she distrusted, she said, a supervisor pressed her to reconsider. UnitedHealth didn’t require her to make diagnoses, she said.

“You’re just encouraged to, because obviously, if you don’t, they come bothering you,” said Isom, who left UnitedHealth to start her own practice in 2022.

UnitedHealth’s doctors in the Journal’s analysis diagnosed the bruising condition, which triggered extra payments of about $1,900 a year at the time, 28 times more often with patients in UnitedHealth Medicare Advantage plans than those in traditional Medicare.

. . .

Jones, the former UnitedHealth doctor in Oregon, said the suggestions included diagnoses based on scant evidence, such as long-term insulin use for patients who had received the drug only once during a long-ago hospital stay.

. . .

The design of the system, he said, could lead to good-faith errors as doctors clicked through all the boxes. “The system is made to have these happy little accidents that end up resulting in a lot of money from taxpayers,” he said.

. . .

Andy Pasternak, an independent family doctor in Reno, Nev., has lower-than-average sickness scores across his practice, records show. He said he gets a per-patient bonus of $2 a month, or $2,256 annually, for the 94 Medicare Advantage patients covered by his contract with UnitedHealth.

Pasternak said UnitedHealth offered to send nurses to visit those patients to diagnose them more fully. The company would pay him $250 for each patient their nurses examined, he said.

“That’s more than I get paid for treating my own patients,” he said. He said the focus on diagnosing has soured him on Medicare Advantage, and made him grateful when patients younger than 65 come to his office.

One UnitedHealth document reviewed by the Journal projected Pasternak could receive as much as $23,250 a year in such payments. A UnitedHealth executive in his area told him in an email his practice also would benefit from any additional diagnoses made by the nurse.

Valerie O’Meara, a former UnitedHealth nurse practitioner, said she never provided treatment for the patients she saw in doctors’ offices in Washington state. “Your job is finding diagnoses, that was clear as a bell,” she said. “I was like, am I finding all these things that the doctors who are taking care of these people didn’t find?”

She said a Minnesota-based UnitedHealth manager urged her to make new diagnoses beyond what doctors had treated. Patients were often confused, she said, about why she, not their own doctor, was examining them. “They don’t tell the patient, the nurse needs to see you to make sure your high-scoring medical problems are checked off this year.”

Chris Henretta, a UnitedHealth Medicare Advantage plan member who lives in The Villages, a retirement community in central Florida, was suspicious when his primary-care doctor diagnosed him as morbidly obese during his annual exam in October.

He is a lifelong weightlifter, plays water volleyball five times a week and has an athletic build.

“I told her I didn’t think I was obese,” Henretta said. When she recorded morbid obesity anyway, he said, he began to “suspect my doctor may have a financial incentive to portray people as higher risk.”

The diagnosis can trigger payments of about $2,400 a year to Medicare Advantage insurers.

“Trusting the Experts Is Not a Feature of Science. It’s the Opposite of Science.”

Over my desk, in the biggest font my printer will print, I have the Latin motto “Nullius in Verba.” That is the motto of the Royal Society of London, the first association for the advancement of science. In English the motto says “on no one’s word” and is usually interpreted to mean that if we are doing science we rely on evidence, and not on the authority of experts. C.S. Peirce said truth is what results from infinite inquiry. Science is a process of asking questions, not a body of unquestionable truths. During the Covid pandemic we were told to stop asking questions and blindly accept the orders of “experts” who the government identified as scientists. Citizens who valued free speech and understood Nullius in Verba rebelled.

Vaccines and antibiotics are two of the greatest achievements in medicine. But both have side-effects and risks. By denying the real side-effects and risks of Covid vaccines, the “experts” destroyed their credibility with the thinking (i.e., the scientific) public. The public’s anger at being lied to was so great that some went so far as to reject all vaccines, even in the frequent situation where on balance the benefits of the vaccine outweigh the side-effects and risks. This was the unnecessary, outrageous, and sad result of government regulators who did not value freedom and did not understand the meaning of “science.”

(p. A1) The rise of Robert F. Kennedy Jr. from fringe figure to the prospective head of U.S. health policy was fueled by skepticism and distrust of the medical establishment—views that went viral in the Covid-19 pandemic.

. . .

Lingering resentment over pandemic restrictions helped Kennedy and his “Make America Healthy Again” campaign draw people from the left and the right, voters who worried about the contamination of food, water and medicine. Many of them shared doubts about vaccines and felt their concerns were ignored by experts or regarded as ignorant.

. . .

(p. A8) Much of Kennedy’s popularity reflects residual pandemic anger—over being told to stay at home or to wear masks; the extended closure of schools and businesses; and vaccine requirements to attend classes, board a plane or eat at a restaurant.

“We weren’t really considering the consequences in communities that were not New York City,” the places where the virus wasn’t hitting as hard, former National Institutes of Health Director Francis Collins said at an event last year.

Authorities focused on ways to stop the disease and failed to consider “this actually, totally disrupts peoples’ lives, ruins the economy and has many kids kept out of school,” Collins said. The U.S. overall took the right approach, he said, but overlooking long-term consequences was “really unfortunate. That’s another mistake we made.”

. . .

. . ., Jessica Malaty Rivera, an epidemiologist with hundreds of thousands of Instagram followers, shared information on the importance of vaccines and face masks. She dismissed unsupported claims as misinformation and described some of their purveyors as grifters.

Looking back, Rivera said her sometimes scolding messages weren’t helpful. “Everybody has been tempted by the slam dunk,” she said. “It’s not an effective way to communicate science. It’s just not.” She and others say they are dialing back the use of the word misinformation, saying it makes people feel they are being called liars or dumb.

During the pandemic, Palmira Gerlach had questions about the Covid-19 vaccines, but doctors “were very dismissive,” the 44-year-old recalled.

Gerlach, a stay-at-home mother outside Pittsburgh, said she falsely told her child’s pediatrician that she got the shot, seeking to avoid judgment. The doctor told her, “Good girl.” Gerlach turned to podcasts featuring Kennedy, drawn to his willingness to question pandemic measures.

. . .

“We were all told in Covid: ‘Trust the experts.’ But that’s not a thing,” Kennedy said in an episode of the “What is Money?” podcast in April [2024]. “Trusting the experts is not a feature of science. It’s the opposite of science. It’s not a feature of democracy.”

Innovative Medical Project Entrepreneur Karikó Long Persevered to Develop mRNA Technology Behind Covid-19 Vaccines

The basic science and technology behind mRNA did not come easy and did not come quick. If the skeptics of Covid-19 vaccines knew this they might be less skeptical because one of the reasons they sometimes give for their skepticism is the speed with which the vaccines were developed. (Other reasons for skepticism I think are more defensible, such as the worry that the authorities downplayed the real side-effects that some vaccine recipients suffered from the vaccines. But on balance I still think the vaccines were a great achievement.) One of the heroes of the long slog is Katalin Karikó. Part of her story is sketched in the passages quoted below. She is a good example of an innovative medical project entrepreneur. When she was named a winner of the Nobel Prize she identified part of what it takes to succeed: “we persevere, we are resilient” (Karikó as quoted in Mosbergen, Loftus, and Zuckerman 2023, p. A2).

(p. A2) The University of Pennsylvania is basking in the glow of two researchers who this week were awarded the Nobel Prize in medicine for their pioneering work on messenger RNA.

Until recently, the school and its faculty largely disdained one of those scientists.

Penn demoted Katalin Karikó, shunting her to a lab on the outskirts of campus while cutting her pay. Karikó’s colleagues denigrated her mRNA research and some wouldn’t work with her, according to her and people at the school. Eventually, Karikó persuaded another Penn researcher, Drew Weissman, to work with her on modifying mRNA for vaccines and drugs, though most others at the school remained skeptical, pushing other approaches.

. . .

. . . on Monday [Oct. 2, 2023], when Karikó and Weissman were awarded the Nobel, on top of prestigious science prizes in recent years, the school expressed a different perspective on their work.

The reversal offers a glimpse of the clubby, hothouse world of academia and science, where winning financial funding is a constant burden, securing publication is a frustrating challenge and those with unconventional or ambitious approaches can struggle to gain support and acceptance.

“It’s a flawed system,” said David Langer, who is chair of neurosurgery at Lenox Hill Hospital, spent 18 years studying and working at Penn and was Karikó’s student and collaborator.

. . .

Penn wasn’t the only institution to doubt Karikó’s belief in mRNA when many other scientists pursued a different gene-based technology. In a reflection of how radical her ideas were at the time, she had difficulty publishing her research and obtaining big grants—prerequisites for those hoping to get ahead in science and gain academic promotions.

Another reason her relationship with the school frayed: Karikó could antagonize colleagues. In presentations, she often was the first to point out mistakes in their work. Karikó didn’t intend to offend, she just felt the need to call out mistakes, she later said.
