the influence of questionable research practices is at the heart of failures to replicate psychological findings, especially in social psychology.But the worst part is an account of social scientists who found serious errors in their own published work and tried to retract it. One journal told an author that they charge $10,000 to publish retractions. Another was told, by the American Sociological Review, that they had no mechanism for retractions, but the authors were welcome to submit their new findings as a separate paper. They did so, but the new paper was rejected with the usual form letter saying the ASR "publishes only the very best submissions." Which was grimly amusing to authors who have realized that the paper the journal did publish contained an invalidating error.
