Sigma Series: Reproducibility in Scientific Research

Tuesday, May 4, 2021

More than 15 years ago, an epidemiologist proposed that publication requirements favoring surprising results combined with naive statistical thresholds meant that most publications were false. Since that conclusion relied on modeling, it was easy to dismiss. In 2011 and 2012, researchers at Bayer and Amgen described their efforts to reproduce dozens of breakthrough papers in cancer, women's health and heart disease: they could verify fewer than a fourth of the topline conclusions. A more systematic effort to replicate psychology studies succeeded with only about a third replicated. That spurred what some have called a 'credibility revolution': Monya Baker discusses these changes. Baker commissions and edits articles on improving science for Nature magazine, where she has worked since 2007.
