FEATURE research over the years and, in my mind, I always plan to go back to that dataset one day and look for other things,” Dr. Prasad said. “I’ve learned over time that the reality is that life sets in, you get moved to other projects, and you just don’t get to do those things.” Aside from these practical factors, proponents also argue that data sharing can accelerate and improve scientific discovery. “For example, competing experts may apply an improved statistical analysis that finds a hidden discovery that the original data-generators missed,” Rafael Irizarry, PhD, professor of biostatistics at the Dana-Farber Cancer Institute at Harvard University, told ASH Clinical News. “Furthermore, examination of data by many experts can help correct errors missed by the analyst of the original project.” Michael Hoffman, PhD, a scientist at the Princess Margaret Cancer Centre and an assistant professor at the University of Toronto, believes the “most offensive” aspect of the NEJM editorial is that the authors chastise potential “research parasites” for potentially disproving original investigators’ work. He contends that a bedrock of science itself is the idea that any conclusions determined by a scientist will be under the scrutiny of other scientists in the field. “That’s what science is all about: It’s about putting forward ideas and testing them with various datasets,” Dr. Hoffman said. “That editors of NEJM do not seem to understand this is incredibly concerning.” So, proponents say, giving outside scientists access to research data is a matter of advancing science. At a minimum, researchers who conduct governmentfunded trials should be required to share any data they gather from the process with the public, as the trials are funded by taxpayers. “They are the actual owners,” Dr. Irizarry says, “so there is an argument to be made that the public’s data are being held hostage.” … And the Case Against While many scientists and publications advocate for open data sharing, the path to complete data enlightenment is not without obstacles. And, if pro–data sharing advocates get their wish, should they be worried about research parasites feeding off of all that open data? One such caveat Drs. Longo and Drazen noted in their editorial is that “outside researchers” (those who were not part of the generation and collection of data) may not fully understand the choices the original investig
