Retractions stigmatize scientific fields, study finds
The study, published this week as a National Bureau of Economic Research working paper, used the PubMed Related Citations Algorithm (PMRA) to fish out papers that are topically similar to retracted articles but written by different authors. After a retraction, the rate at which these related papers were cited dropped by 5.7% relative to a selection of control papers that were not related to a retraction.
