New study published on retractions in biomedical papers

A new study on retractions shows that the system is effective for alerting the community to invalid work.  The Scholarly Kitchen discusses an article ("Governing knowledge in the scientific community: Exploring the role of retractions in biomedicine“ pub in Research Policy, March 2012 by, J Furman, K Jensen, and F Murray) that reports on a study of 677 article retractions identified in MEDLINE between 1972 and 2006. The results show that the retraction system is fast (nearly 15% of all retractions took place during the year of publication and 50% within 24 months); democratic (there does not appear to be bias due to geographical location or institutional affiliation); and the effect of issuing retractions on article citations is severe and long-lived.
