Adhering faithfully to the scientific method is at the very heart of psychological inquiry. It requires scientists to be passionately dispassionate, to be intensely interested in scientific questions but not wedded to the answers. It asks that scientists not personally identify with their past work or theories — even those that bear their names — so that science as a whole can inch ever closer to illuminating elusive truths. That compliance isn’t so easy. But those who champion the so-called replication revolution in psychological science believe that it is possible — with the right structural reforms and personal incentives.
