Retraction Watch is always interesting reading. Their recent posts are no exception. In some cases, one wonders why the referees did not spot the issues that led to articles being retracted.
This one is the opposite of a gem. Three scientists have published an article which cites parody site The Onion as a source – for the existence of a children’s menu on the back of the U.S. Constitution (shades of National Treasure!). The journal in question has an impact factor of 4.5, but apparently has some gaps in peer review (thanks to 0xDE for bringing this to my attention).
Winston Churchill once stated that “it has been said that democracy is the worst form of government except for all those other forms that have been tried from time to time.” Peer review is, I guess, much the same.
