In October 2011, the journal Nature reported that published retractions had increased tenfold over the past decade, while the number of published papers had increased by just 44 percent. In 2010 The Journal of Medical Ethics published a study finding the new raft of recent retractions was a mix of misconduct and honest scientific mistakes. Several factors are at play here, scientists say. To survive professionally, scientists feel the need to publish as many papers as possible, and to get them into high-profile journals. And sometimes they cut corners or even commit misconduct to get there.
