RAND developed the Delphi method in the 1950s, originally to forecast the impact of technology on warfare. The method entails a group of experts who anonymously reply to questionnaires and subsequently receive feedback in the form of a statistical representation of the "group response," after which the process repeats itself. The goal is to reduce the range of responses and arrive at something closer to expert consensus. The Delphi Method has been widely adopted and is still in use today.
REPORT
An analysis of 30 insurgencies worldwide between 1978 and 2008 determined what factors were ultimately correlated with success or defeat. Comparing Afghanistan in early 2011 against this scorecard results in an uncertain outcome for the conflict there, but the findings may help provide additional guidance as operations continue.
NEWS RELEASE
Researchers have developed a new method of eliciting and analyzing opinions from a large group of experts and laypeople to aid complex decisionmaking, adapting online and social media technologies to lower the cost of such activities while expanding the types of people who can be queried.
