What universities can learn from one of science’s biggest frauds | Nature.com

Holly Else, Reporter at Nature Research writes, Detailed analysis of misconduct investigations into huge research fraud suggests institutional probes aren’t rigorous enough.

By day, Andrew Grey studies bone health. But over the past few years, he’s developed another speciality: the case of one of science’s most prolific fraudsters.

From 1996 to 2013, Yoshihiro Sato, a Japanese bone-health researcher plagiarized work, fabricated data and forged authorships — prompting retractions of more than 60 studies in the scholarly literature so far. Grey and colleagues at the University of Auckland in New Zealand and the University of Aberdeen, UK, are among the researchers who have raised concerns about Sato’s work over the past decade or so, and they have studied the case in detail — in particular, how universities involved in the research investigated concerns about his work and allegations of misconduct.

At the World Conference on Research Integrity in Hong Kong from 2 to 5 June, Grey’s team described its years-long efforts to clean up Sato’s literature, and presented its analysis of the inquiries conducted by four universities in Japan and the United States ensnared in the scandal (the team published its analysis of three investigations in a paper in February¹). Grey says their findings provide evidence to support a growing view in the academic community: that university investigations into research misconduct are often inadequate, opaque and poorly conducted. They challenge the idea that institutions can police themselves on research integrity and propose that there should be independent organizations to evaluate allegations of research fraud should...

Kurume University asked a committee of statisticians and medical researchers to investigate 39 papers authored by Sato, and found some data falsification and inappropriate authorships. It said that it cannot conclude whether fraud was involved in another 32 papers because Sato is dead and records for these experiments no longer exist. Hirosaki University — whose 2017 investigation found “research irregularities” in 14 research papers, 7 of which had already been retracted — did not respond to Nature’s request for comment.
