This seems like something ripped from the pages of The Onion, but the Government Accountability Office just completed its study of a study ordered by the Pentagon into studies ordered by the Pentagon.
In 2010, Defense Secretary Robert Gates was interested in the growing number of studies at the Pentagon and their costs so he ordered a study of the studies. Yet, by the time that the GAO was recently called in the Pentagon researchers had only been able to look at nine studies, but was unable to “readily retrieve documentation” for six of the reports. The GAO criticized the study of studies in its study. However, the Pentagon has announced that it only “partially concurs” with the GAO’s report. Presumably, it will have to study those findings further. The ball is now in the Pentagon’s court.
