PART 2 READING
TEXT B
Jan Hendrik Schon's success seemed too good to be
true, and it was. In only four years as a physicist at Bell Laboratories, Schon,
32, had co-authored 90 scientific papers—ne every 16 days, which astonished his
colleagues,and made them suspicious. When one co-worker noticed that the same
table of data appeared in two separatepapers--which also happened to appear in
the two most prestigious scientific journals in the world, Science
andNature--the jig was up. In October 2002, a Bell Labs investigation found that
Schon had falsified and fabricateddata. His career as a scientist was
finished.
If it sounds a lot like the fall of Hwang Woo Suk--the South Korean researcher who fabricated his evidenceabout cloning human cells--it is. Scientific scandals, which are as old as science itself, tend to follow similarpatterns of hubris and comeuppance. Afterwards, colleagues wring their hands and wonder how such malfeasancecan be avoided in the future. But it never is entirely. Science is built on the honor system; the method of peer-review, in which manuscripts arc evaluated by experts in the field, is not meant to catch cheats. In recent years, ofcourse, the pressure on scientists to publish in the top journals has increased, making the journals much morecrucial to career success. The questions raised anew by Hwang's fall are whether Nature and Science have becometoo powerful as arbiters of what science reaches the public, and whether the journals are up to their task asgatekeepers.
Each scientific specialty has its own set of journals. Physicists have Physical Review Letters; cell biologistshave Cell; neuroscientists have Neuron, and so forth. Science and Nature, though, are the only two major journalsthat cover the gamut of scientific disciplines, from meteorology and zoology to quantum physics and chemistry. Asa result, journalists look to them each week for the cream of the crop of new science papers. And scientists look tothe journals in part to reach journalists. Why do they care? Competition for grants has gotten so fierce that scientistshave sought popular renown to gain an edge over their rivals. Publication in specialized journals will win theaccolades of academics and satisfy the publish-or-perish imperative, but Science and Nature come with the addedbonus of potentially getting your paper written up in The New York Times and other publications.
Scientists are also trying to reach other scientists through Science and Nature, not just the public. Scientiststend to pay more attention to the Big Two than to other journals. When more scientists know about a particularpaper, they're more apt to cite it in their own papers. Being oft-cited will increase a scientist's "Impact Factor", ameasure of how often papers are cited by peers. Funding agencies use the Impact Factor as a rough measure of theinfluence of scientists they're considering supporting.
Whcther the clamor to appear in these journals has any bearing on their ability to catch fraud is another matter.The fact is that fraud is terrifically hard to spot. Consider the process Science used to evaluate Hwang's 2005article. Science editors recognized the manuscript's import almost as soon as it arrived. As part of the standardprocedure, they sent it to two members of its Board of Reviewing Editors, who recommended that it go out for peerreview (about 30 percent of manuscripts pass this test). This recommendation was made not on the scientificvalidity of the paper, but on its "novelty, originality, and trendiness," says Denis Duboule, a geneticist at theUniversity of Geneva and a member of Science's Board of Reviewing Editors, in the January 6 issue of Science.
After this, Science sent the paper to three stem-cell experts, who had a week to look it over. Their commentswere favorable. How were they to know that the data was fraudulent? "You look at the data and do not assume it'sfraud," says one reviewer, anonymously, in Science.
In the end, a big scandal now and then isn't likely to do much damage to the big scientific journals. Whateditors and scientists worry about more arc the myriad smaller infractions that occur all the time, and which arcatmost impossible to dctcct. A Nature survey of scientists published last June found that one-third of allrespondents had committed some forms of misconduct. Tbesc included falsifying research data and having"questionable relationships" with students and subjects--both charges "leveled against Hwang. Nobody reallyknows if this kind of fraud is on tbe rise, but it is worrying.
Science editors don't have any plans to change the basic editorial
peer-review process as a result of the Hwangscandal. They do have plans to
scrutinize photographs more closely in an effort to spot instances of fraud, but
thatpolicy change had akcady been decided when the scandal struck. And even if
it had been in place, it would nothave revealed that Hwang had misrepresented
photographs from two stem cell colonies as coming from 11colonies. With the
financial and deadline pressures of the publishing industry, it's unlikely that
the journals are
going to take markedly stronger measures to vet
m_anuscripts. Beyond replicating the experiments themselves,which would be
impractical, it's difficult to see what they could do to make science beyond the
honor system.
