Society Needs Regulations to Prevent Research Abuses
A tension exists between scientists/doctors and government regulators.
[Editor's Note: Our Big Moral Question this month is, "Do government regulations help or hurt the goal of responsible and timely scientific innovation?"]
Government regulations help more than hurt the goal of responsible and timely scientific innovation. Opponents might argue that without regulations, researchers would be free to do whatever they want. But without ethics and regulations, scientists have performed horrific experiments. In Nazi concentration camps, for instance, doctors forced prisoners to stay in the snow to see how long it took for these inmates to freeze to death. These researchers also removed prisoner's limbs in order to try to develop innovations to reconnect these body parts, but all the experiments failed.
Researchers in not only industry, but also academia have violated research participants' rights.
Due to these atrocities, after the war, the Nuremberg Tribunal established the first ethical guidelines for research, mandating that all study participants provide informed consent. Yet many researchers, including those in leading U.S. academic institutions and government agencies, failed to follow these dictates. The U.S. government, for instance, secretly infected Guatemalan men with syphilis in order to study the disease and experimented on soldiers, exposing them without consent to biological and chemical warfare agents. In the 1960s, researchers at New York's Willowbrook State School purposefully fed intellectually disabled children infected stool extracts with hepatitis to study the disease. In 1966, in the New England Journal of Medicine, Henry Beecher, a Harvard anesthesiologist, described 22 cases of unethical research published in the nation's leading medical journals, but were mostly conducted without informed consent, and at times harmed participants without offering them any benefit.
Despite heightened awareness and enhanced guidelines, abuses continued. Until a 1974 journalistic exposé, the U.S. government continued to fund the now-notorious Tuskegee syphilis study of infected poor African-American men in rural Alabama, refusing to offer these men penicillin when it became available as effective treatment for the disease.
In response, in 1974 Congress passed the National Research Act, establishing research ethics committees or Institutional Review Boards (IRBs), to guide scientists, allowing them to innovate while protecting study participants' rights. Routinely, IRBs now detect and prevent unethical studies from starting.
Still, even with these regulations, researchers have at times conducted unethical investigations. In 1999 at the Los Angeles Veterans Affairs Hospital, for example, a patient twice refused to participate in a study that would prolong his surgery. The researcher nonetheless proceeded to experiment on him anyway, using an electrical probe in the patient's heart to collect data.
Part of the problem and consequent need for regulations is that researchers have conflicts of interest and often do not recognize ethical challenges their research may pose.
Pharmaceutical company scandals, involving Avandia, and Neurontin and other drugs, raise added concerns. In marketing Vioxx, OxyContin, and tobacco, corporations have hidden findings that might undercut sales.
Regulations become increasingly critical as drug companies and the NIH conduct increasing amounts of research in the developing world. In 1996, Pfizer conducted a study of bacterial meningitis in Nigeria in which 11 children died. The families thus sued. Pfizer produced a Nigerian IRB approval letter, but the letter turned out to have been forged. No Nigerian IRB had ever approved the study. Fourteen years later, Wikileaks revealed that Pfizer had hired detectives to find evidence of corruption against the Nigerian Attorney General, to compel him to drop the lawsuit.
Researchers in not only industry, but also academia have violated research participants' rights. Arizona State University scientists wanted to investigate the genes of a Native American group, the Havasupai, who were concerned about their high rates of diabetes. The investigators also wanted to study the group's rates of schizophrenia, but feared that the tribe would oppose the study, given the stigma. Hence, these researchers decided to mislead the tribe, stating that the study was only about diabetes. The university's research ethics committee knew the scientists' plan to study schizophrenia, but approved the study, including the consent form, which did not mention any psychiatric diagnoses. The Havasupai gave blood samples, but later learned that the researchers published articles about the tribe's schizophrenia and alcoholism, and genetic origins in Asia (while the Havasupai believed they originated in the Grand Canyon, where they now lived, and which they thus argued they owned). A 2010 legal settlement required that the university return the blood samples to the tribe, which then destroyed them. Had the researchers instead worked with the tribe more respectfully, they could have advanced science in many ways.
Part of the problem and consequent need for regulations is that researchers have conflicts of interest and often do not recognize ethical challenges their research may pose.
Such violations threaten to lower public trust in science, particularly among vulnerable groups that have historically been systemically mistreated, diminishing public and government support for research and for the National Institutes of Health, National Science Foundation and Centers for Disease Control, all of which conduct large numbers of studies.
Research that has failed to follow ethics has in fact impeded innovation.
In popular culture, myths of immoral science and technology--from Frankenstein to Big Brother and Dr. Strangelove--loom.
Admittedly, regulations involve inherent tradeoffs. Following certain rules can take time and effort. Certain regulations may in fact limit research that might potentially advance knowledge, but be grossly unethical. For instance, if our society's sole goal was to have scientists innovate as much as possible, we might let them stick needles into healthy people's brains to remove cells in return for cash that many vulnerable poor people might find desirable. But these studies would clearly pose major ethical problems.
Research that has failed to follow ethics has in fact impeded innovation. In 1999, the death of a young man, Jesse Gelsinger, in a gene therapy experiment in which the investigator was subsequently found to have major conflicts of interest, delayed innovations in the field of gene therapy research for years.
Without regulations, companies might market products that prove dangerous, leading to massive lawsuits that could also ultimately stifle further innovation within an industry.
The key question is not whether regulations help or hurt science alone, but whether they help or hurt science that is both "responsible and innovative."
We don't want "over-regulation." Rather, the right amount of regulations is needed – neither too much nor too little. Hence, policy makers in this area have developed regulations in fair and transparent ways and have also been working to reduce the burden on researchers – for instance, by allowing single IRBs to review multi-site studies, rather than having multiple IRBs do so, which can create obstacles.
In sum, society requires a proper balance of regulations to ensure ethical research, avoid abuses, and ultimately aid us all by promoting responsible innovation.

George Papanicolaou (1883-1962), Greek-born American physician developed a simple cytological test for cervical cancer in 1928.
For decades, women around the world have made the annual pilgrimage to their doctor for the dreaded but potentially life-saving Papanicolaou test, a gynecological exam to screen for cervical cancer named for Georgios Papanicolaou, the Greek immigrant who developed it.
The Pap smear, as it is commonly known, is credited for reducing cervical cancer mortality by 70% since the 1960s; the American Cancer Society (ACS) still ranks the Pap as the most successful screening test for preventing serious malignancies. Nonetheless, the agency, as well as other medical panels, including the US Preventive Services Task Force and the American College of Obstetrics and Gynecology are making a strong push to replace the Pap with the more sensitive high-risk HPV screening test for the human papillomavirus virus, which causes nearly all cases of cervical cancer.
So, how was the Pap developed and how did it become the gold standard of cervical cancer detection for more than 60 years?
Born on May 13, 1883, on the island of Euboea, Greece, Georgios Papanicolaou attended the University of Athens where he majored in music and the humanities before earning his medical degree in 1904 and PhD from the University of Munich six years later. In Europe, Papanicolaou was an assistant military surgeon during the Balkan War, a psychologist for an expedition of the Oceanographic Institute of Monaco and a caregiver for leprosy patients.
When he and his wife, Andromache Mavroyenous (Mary), arrived at Ellis Island on October 19, 1913, the young couple had scarcely more than the $250 minimum required to immigrate, spoke no English and had no job prospects. They worked a series of menial jobs--department store sales clerk, rug salesman, newspaper clerk, restaurant violinist--before Papanicolaou landed a position as an anatomy assistant at Cornell University and Mary was hired as his lab assistant, an arrangement that would last for the next 50 years.
Papanikolaou would later say the discovery "was one of the greatest thrills I ever experienced during my scientific career."
In his early research, Papanikolaou used guinea pigs to prove that gender is determined by the X and Y chromosomes. Using a pediatric nasal speculum, he collected and microscopically examined vaginal secretions of guinea pigs, which revealed distinct cell changes connected to the menstrual cycle. He moved on to study reproductive patterns in humans, beginning with his faithful wife, Mary, who not only endured his almost-daily cervical exams for decades, but also recruited friends as early research participants.
Writing in the medical journal Growth in 1920, the scientist outlined his theory that a microscopic smear of vaginal fluid could detect the presence of cancer cells in the uterus. Papanikolaou would later say the discovery "was one of the greatest thrills I ever experienced during my scientific career."
At this time, cervical cancer was the number one cancer killer of American women but physicians were skeptical of these new findings. They continued to rely on biopsy and curettage to diagnose and treat the disease until Papanicolaou's discovery was published in American Journal of Obstetrics and Gynecology. An inexpensive, easy-to-perform test that could detect cervical cancer, precancerous dysplasia and other cytological diseases was a sea change. Between 1975 and 2001, the cervical cancer rate was cut in half.
Papanicolaou became Emeritus Professor at Cornell University Medical College and received numerous awards, including the Albert Lasker Award for Clinical Medical Research and the Medal of Honor from the American Cancer Society. His image was featured on the Greek currency and the US Post Office issued a commemorative stamp in his honor. But international acclaim didn't lead to a more relaxed schedule. The researcher continued to work seven days a week and refused to take vacations.
After nearly 50 years, Papanicolaou left Cornell to head and develop the Cancer Institute of Miami. He died of a heart attack on February 19, 1962, just three months after his arrival. Mary continued to work in the renamed Papanicolaou Cancer Research Institute until her death 20 years later.
The annual pap smear was originally tied to renewing a birth control prescription. Canada began recommending Pap exams every three years in 1978. The United States followed suit in 2012, noting that it takes many years for cervical cancer to develop. In September 2020, the American Cancer Society recommended delaying the first gynecological pelvic exam until age 25 and replacing the Pap test completely with the more accurate human papillomavirus (HPV) test every five years as the technology becomes more widely available.
Not everyone agrees that it's time to do away with this proven screening method, though. The incidence rate of cervical cancer among Hispanic women is 28% higher than for white women, and Black women are more likely to die of cervical cancer than any other racial or ethnicities.
Whether the Pap is administered every year, every three years or not at all, Papanicolaou will always be known as the medical hero who saved countless women who would otherwise have succumbed to cervical cancer.
