Researchers in U.S. May Have Received Millions in Duplicate Funding, Analysis Suggests
Although the researchers could not definitively determine whether the similar grants were true duplicates -- this would require access to the full grant files, which were not publicly available -- they found strong evidence that tens of millions of dollars may have been spent on grants where at least a portion was already being funded. In the most recent five years (2007-2011), they identified 39 similar grant pairs involving more than $20 million.
"It is quite possible that our detection software missed many cases of duplication," Garner said. "If text similarity software misses as many cases of funding duplications as it does plagiarism of scientific papers we've studied, then the extent of duplication could be much larger. It could be as much as 2.5 percent of total research funding, equivalent to $5.1 billion since 1985."
Co-researcher and medical science ethicist Michael B. Waitzkin said, "In line with the Government Accountability Office report issued February 2012, these findings suggest the research community should undertake a more thorough investigation of the true extent of duplication and establish, clearer and more consistent guidance and coordination of grant and contract funding across agencies, both public and private."
The study did not reveal specific principal investigators or research organizations identified as double-dippers, but said that no instances of double dipping were found at Virginia Tech.
