Needless to say, it has become impossible for researchers to read all the articles published in their fields of interest, because if they did that, they would not have any time left to conduct experiments of their own. To avoid drowning in the information overload, researchers have developed multiple strategies how to survive and navigate their way through all this published data. These strategies include relying on recommendations of colleagues, focusing on articles published in high-impact journals, only perusing articles that are directly related to one’s own work or only reading articles that have been cited or featured in major review articles, editorials or commentaries. As a stem cell researcher, I can use the above-mentioned strategies to narrow down the stem cell articles that I ought to read to the manageable number of about three or four articles a day. However, scientific innovation in research is fueled by the cross-fertilization of ideas. The most creative ideas are derived from combining seemingly unrelated research questions. Therefore, the challenge for me is to not only stay informed about important developments in my own areas of interest. I also need to know about major developments in other scientific domains such as network theory, botany or neuroscience, because discoveries in such “distant” fields could inspire me to develop innovative approaches in my own work.
In order to keep up with scientific developments outside of my area of expertise, I have begun to rely on high-quality science journalism, which can be found in selected print and online publications or in science blogs. Good science journalists accurately convey complex scientific concepts in simple language, without oversimplifying the actual science. This is easier said than done, because it requires a solid understanding of the science as well as excellent communication skills. Most scientists are not trained to communicate to the general audience and most journalists have had very limited exposure to actual scientific work. To become good science journalists, either scientists have to be trained in the art of communicating results to non-specialists or journalists have to acquire the scientific knowledge pertinent to the topics they want to write about. The training of science journalists requires time, resources and good mentors.
Once they have completed their training and start working as science journalists, they still need adequate time, resources and mentors. When writing about an important new scientific development, good science journalists do not just repeat the information provided by the researchers or contained in the press release of the university where the research was conducted. Instead, science journalists perform the necessary fact-checking to ensure that the provided information is indeed correct. They also consult the scientific literature as well as other scientific experts to place the new development in the context of the existing research. Importantly, science journalists then analyze the new scientific development, separating the actual scientific data from speculation as well as point out limitations and implications of the work.
Unfortunately, I do not think that it is widely appreciated how important high-quality science journalism is and how much effort it requires. Limited resources, constraints on a journalist’s time and the pressure to publish sensationalist articles that exaggerate or oversimplify the science in order to attract a larger readership can compromise the quality of the work. Two recent examples illustrate this: The so-called Jonah Lehrer controversy, where the highly respected and popular science journalist Jonah Lehrer was found to fabricate quotes, plagiarize and oversimplify the research as well as the more recent case where the Japanese newspaper Yomiuri Shimbun ran a story about the use of induced pluripotent stem cells to treat patients with heart disease, which turned out to be a fraudulent claim of the researcher. The case of Jonah Lehrer was a big shock for me. I had enjoyed reading a number of his articles and blogs that he had written and, at first, it was difficult for me to accept that his work contained so many errors and evidence of misconduct. Boris Kachka has recently written a very profound analysis of the Jonah Lehrer controversy in New York Magazine:
Lehrer was the first of the Millennials to follow his elders into the dubious promised land of the convention hall, where the book, blog, TED talk, and article are merely delivery systems for a core commodity, the Insight.The Insight is less of an idea than a conceit, a bit of alchemy that transforms minor studies into news, data into magic. Once the Insight is in place—Blink, Nudge, Free, The World Is Flat—the data becomes scaffolding. It can go in the book, along with any caveats, but it’s secondary. The purpose is not to substantiate but to enchant.
When I read Kachka’s description of why Lehrer was able to get away with his fabrications and over-simplifications, I realized that it was probably because Lehrer gave us the narratives we wanted to believe. He provided “Insight” - portraying scientific research in a false shroud of certainty and simplicity. Even though many of us look forward to overcoming intellectual laziness in our own work, we may not be used to challenging our “inner swine dog” when we learn about scientific topics outside of our own areas of expertise. This is precisely why we need good science journalists, who challenge us intellectually by avoiding over-simplifications.
This was not the first incident of scientific fraud in the world of stem cell research and it unfortunately will not be the last. What makes this incident noteworthy is how the newspaper Yomiuri Shimbun responded to their reporting of these fraudulent claims. They removed the original story from their page and issued public apologies for their poor reporting. The English-language version of the newspaper listed the mistakes in an article entitled “iPS REPORTS--WHAT WENT WRONG / Moriguchi reporting left questions unanswered”. These problems include inadequate fact-checking regarding the researcher’s claims and affiliations by the reporter and lack of consultation with other scientists whether the findings sounded reasonable. Interestingly, the reporter had identified some red flags and concerns:
--Moriguchi had not published any research on animal experiments.
--The reporter had not been able to contact people who could confirm the iPS cell clinical applications.
--Moriguchi's affiliation with Harvard University could not be confirmed online.
--It was possible that different cells, instead of iPS cells, had been effective in the treatments.
--It was odd that what appeared to be major world news was appearing only in the form of a poster at a science conference.
--The reporter wondered if it was really possible that transplant operations using iPS cells had been approved at Harvard.
The reporter sent the e-mail to three others, including another news editor in charge of medical science, on the same day, and the reporter's regular updates on the topic were shared among them.
The science reporter said he felt "at ease" after informing the editors about such dubious points. After receiving explanations from Moriguchi, along with the video clip and other materials, the reporter sought opinions from only one expert and came to believe the doubts had been resolved.
Effective as of next Thursday, The Yomiuri Shimbun will take disciplinary action against the following officials and employees:
--Yoshimitsu Ohashi, senior managing director and managing editor of the company, and Takeshi Mizoguchi, corporate officer and senior deputy managing editor, will each return 30 percent of their remuneration and salary for two months.
--Fumitaka Shibata, a deputy managing editor and editor of the Science News Department, will be replaced and his salary will be reduced.
--Another deputy managing editor in charge of editorial work for the Oct. 11 edition will receive an official reprimand.
--The salaries of two deputy editors of the Science News Department will be cut.
--A reporter in charge of the Oct. 11 series will receive an official reprimand.
