|May 2015||The Career Effects of Scandal: Evidence from Scientific Retractions|
with Pierre Azoulay, Alessandro Bonatti: w21146
We investigate how the scientific community's perception of a scientist's prior work changes when one of his articles is retracted. Relative to non-retracted control authors, faculty members who experience a retraction see the citation rate to their earlier, non-retracted articles drop by 10% on average, consistent with the Bayesian intuition that the market inferred their work was mediocre all along. We then investigate whether the eminence of the retracted author and the cause of the retraction (fraud vs. mistake) shape the magnitude of the penalty. We find that eminent scientists are more harshly penalized than their less distinguished peers in the wake of a retraction, but only in cases involving fraud or misconduct. When the retraction event had its source in “honest mistakes,” we fin...

To what extent does "false science" impact the rate and direction of scientific change? We examine the impact of more than 1,100 scientific retractions on the citation trajectories of articles that are related to retracted papers in intellectual space but were published prior to the retraction event. Our results indicate that following retraction and relative to carefully selected controls, related articles experience a lasting five to ten percent decline in the rate of citations received. This citation penalty is more severe when the associated retracted article involves fraud or misconduct, relative to cases where the retraction occurs because of honest mistakes. In addition, we find that the arrival rate of new articles and funding flows into these fields decrease after a retraction. We...
