The journal Science just published a study reporting that top scientists were unable to reproduce the results claimed by 75% of social psychology studies and 50% of cognitive psychology ones. All of the studies appeared in top-ranked journals.
Some scientists, I’m sure, are reeling that their work has been challenged. But I like the attitude expressed by Brian Nosek, a prominent researcher who led the reproduction study. “Scepticism is a core part of science,” he told journalists, “and we need to embrace it. . . . We should be our own worst critics,”
