There are hundreds of think tanks based in Washington, making it difficult to tell where the policy comes from: the White House or unelected officials. During the Reagan era, for example, there were almost 200 employees at conservative think tanks who served as government officials or consultants for his administration. But what do they actually believe?
New research by Richard Hanania and Max Abrahms has found that think tanks are much more hawkish than International Relations scholars, even controlling for ideology.
