It’s hard to argue against the power of science. From studies that evaluate the latest dietary trend to experiments that illuminate predictors of happiness, people have come to increasingly look at scientific results as concrete, reliable facts that can govern how we think and act.Related Content Scientists Replicated 100 Psychology Studies, and Fewer Than Half Got the Same ResultsBut over the past several years, a growing contingent of scientists has begun to question the accepted veracity of published research—even after it’s cleared the hurdles of peer review and appears in widely respected journals. The problem is a pervasive inability to replicate a large proportion of the results across numerous disciplines.In 2005, for instance, John Ioannidis, a professor of medicine at Stanford University, used several simulations to show that scientific claims are more likely to be false than true. And this past summer Brian Nosek, a professor of psychology at the University of Virginia, attempted to replicate the findings of 100 psychology studies and found that only 39 percent of the results held up under rigorous re-testing.
