Ethics and fraud

Editorial Nature 439
117-118 (12 January 2006)
The trajectory of the Hwang scandal highlights the shortness of the path between unethical behaviour and outright misconduct.
The fall of Woo Suk Hwang represents perhaps the highest-profile case in the sorry history of research misconduct. The sheer Shakespearian drama of the Korean cell biologist's eclipse, surrounded by fawning courtiers and plotting groups of acolytes and enemies and in full view of the television cameras, has left few researchers of any discipline, anywhere in the world, unaware of its circumstances.

But what really makes the Hwang case special is the importance of the impugned results (W. S. Hwang et al. Science 303, 1669–1674; 2004 and 308, 1777–1783; 2005). The claimed cloning of human embryos placed Hwang at the forefront of stem-cell research, perhaps the most acclaimed and contentious sphere of modern science. It is also the first major misconduct case to occur during the modern era of carefully patented biology, in which scientists may aspire not just to fame, but to fortune as well.

All of this raises some general questions about ethics and fraud that researchers had perhaps hoped were put to bed a long time ago. Many of these questions were last publicly addressed in the long and painful aftermath of the Baltimore case, in which a junior researcher, Thereza Imanishi-Kari, was accused of fraud in the laboratory of one of the United States' leading microbiologists.

David Baltimore was eventually vindicated and is today president of the California Institute of Technology. But when the allegations were made, the National Institutes of Health opened an Office of Scientific Integrity, which was later downgraded but continues to support fraud investigations at US universities while seeking to get academics to teach their students about ethics and misconduct. This system, imperfect as it may be, is still more advanced than that of many other nations. Elsewhere in the world, cases of fraud have highlighted considerable shortcomings in the mechanisms for responding to misconduct.

"The US system for dealing with fraud, imperfect as it may be, is still more advanced than that of many other nations."

Another celebrated fraud case involved Jan Hendrik Schön, a physicist at Bell Laboratories in Murray Hill, New Jersey, who was found guilty in 2002 of fabricating results in a massive and influential string of papers on superconductivity. However, the general view of the Schön case, outside the discipline directly involved at least, has been that no innocent civilians were hurt, and the fraud was unearthed and duly punished. There is almost a nagging sympathy for how such a smart young man could be so stupid.

The scope of the Hwang scandal tends to leave these and other recent misconduct cases in the shade, however. Although the full facts of the case remain unknown, its multidimensional outline is already clear. Barely a stone was left unturned in his lab's attempts to secure a positive result. Egg donors were energetically sought from every conceivable source ― including from junior researchers inside the laboratory itself, where allegations of coercion have been made. In the end, a result was claimed and the paper published in the complete absence of genuine scientific evidence to support it.

This will surely leave some people asking: if this single cell in the body of science was so malignant, how fares the rest? This is an awkward question and one that many in the community will seek to evade by referring to the fact that it happened in South Korea and couldn't happen here (wherever 'here' happens to be). And it is true that standards of oversight at many laboratories would, at least in theory, make this kind of scenario improbable. However, research ― not least in the dynamic and fiercely competitive field of reproductive biology ― is increasingly conducted through international collaborations. These often involve working with colleagues in countries, including China and South Korea, where mechanisms for supervising ethics and investigating misconduct are at relatively early stages of development.

"This will surely leave people asking: if this single cell in the body of science was so malignant, how fares the rest?"

It therefore falls to scientists who take research ethics seriously to confront the question head on, and to determine what steps should be taken to redouble our efforts to secure standards in both the ethics and conduct of research.

Hand in hand
A first step is to acknowledge that sound ethics and good research practice go hand in hand. The international stem-cell community showed some reluctance to distance itself from Hwang when serious questions were raised in this journal in May 2004 about the manner in which eggs had been obtained for his experiments (see Nature 429, 3; 2004).

As soon as his main US collaborator, Gerald Schatten of the University of Pittsburgh, announced in November that he was bailing out of his collaboration with Hwang (see Nature 438, 262–263; 2005), people began to speculate that Schatten must know there was a problem with the result of the seminal 2004 paper. After all, they inferred, no one would leave a wildly successful research group over ethical transgressions. Or would they?

The leadership of the scientific community has long argued for a solid line to be drawn between ethical transgressions ― not informing patients of their rights, sexually harassing staff, coercing junior colleagues, that sort of thing ― and actual research misconduct, which refers to the fabrication, falsification or plagiarism of scientific evidence.

In the wake of the Baltimore scandal, a congressionally mandated commission chaired by Kenneth Ryan called for a broader definition of research misconduct that would embrace some forms of malfeasance beyond fabrication, falsification and plagiarism. His definition didn't cover bioethics, but it did class any breach of research regulations as misconduct.

Ryan's proposal was roundly condemned in the community, which fought a lengthy and successful battle to derail it. Researchers feared that the extension of misconduct investigations to embrace all kinds of professional laxity would lead to endless, fruitless investigation and, in particular, elicit groundless allegations from junior laboratory malcontents.

It is certainly true that there's a distinction between personal misbehaviour in the lab and outright scientific fraud, and it is perhaps as well that special investigative procedures are retained exclusively for the investigation of the latter. Furthermore, the question of what constitutes an ethical transgression may vary between societies that elect to impose different rules, whereas scientific fraud knows no borders.

In view of the pattern of behaviour that led up to Hwang's disgrace, however, no one should argue ever again that despotism, abuse of junior colleagues, promiscuous authorship on scientific papers or undisclosed payment of research subjects can be tolerated on the grounds of eccentricity or genius. Research ethics matter immensely to the health of the scientific enterprise. Anyone who thinks differently should seek employment in another sphere.

There are still many people who is on Dr. Hwang's side.

Scientist in stem cell fraud apologizes, but shifts blame

SEOUL, South Korea -- Researcher Hwang Woo-suk asked for forgiveness Thursday
from fellow South Koreans for his fraudulent claims of human stem cell breakthroughs,
but blamed the scandal on junior researchers who he said deceived him.

Paralyzed Boy Let Down by South Korean Stem Cell Fraud

Hopes Founder on 'Big Lie'
Scientific scandal has shattered the vow made by a South Korean veterinarian that cloned stem cells would help a paralyzed boy walk.
Los Angeles Times By Barbara Demick January 9, 2006
In a lengthy and emotional interview in the basement of Neulsaerom Church in this beachfront community 18 miles southwest of downtown Seoul,
Kim described how members of this otherwise ordinary family of modest means became unwitting participants in ? and victims of ? one of the biggest science scandals of all time.
"Everyone was misled by Hwang. We worked with him under the belief that he was producing stem cells," said Kim,
who smiled serenely through the wrenching account of his family's tragedy, saying their faith has allowed them to persevere.
"We believe in God," he said, "not Hwang."
The following year, doctors at Gil informed Kim that his son had been chosen from a group of paralyzed patients
as a participant in Hwang's groundbreaking research into creating the first cloned human embryo for therapeutic purposes.
"With this man's help, you will be able to go back to school," Kim recalled telling his son.
The boy gave three skin samples taken under local anesthesia. His case appeared in a now-discredited paper published last May in the U.S.-based Science magazine
in which Hwang claimed to have produced genetically matching stem cell lines from 11 patients.
Hyeoni is the only one whose name has been made public.
Hwang, who was fond of displaying a photo of himself and Hyeoni, told people that the boy
would be the first in line when his research was sufficiently advanced for stem cells to be injected into a human patient.

Schatten said that Hwang had repeatedly denied the rumor and that he had believed
Hwang until yesterday. "I now have information that leads me to believe he had misled
me," Schatten said. "My trust has been shaken. I am sick at heart. I am not going to be
able to collaborate with Woo Suk."
