The United States faces a serious but silent intellectual crisis: U.S. national security elites have separated into two tribes of specialists, technical and nontechnical, who are incapable of communicating with each other. The implications of the divide between experts in science and technology on one hand and experts in politics on the other are dangerous and far-reaching. If the United States policymaking community cannot bridge the gap between these communities, we risk making mistakes with repercussions running all the way from wasting scarce resources to war.
While hardly a golden age of national security policy decision-making, the Cold War set boundaries on science and politics, both of which served the overall goal of avoiding -- or winning -- a war with the Soviet Union. For better or for worse, the scientists, engineers, military officers and civilian strategists of the national security establishment were all yoked together toward this common purpose.
With the Cold War over, the natural bureaucratic tendency of "stovepiping" has taken over. Stovepipes are the institutional and cultural barriers that prevent different groups of experts from understanding or cooperating with each other on everything from terminology to budgets and, ultimately, goals. Fed into stovepipes, national security problems get broken into ever smaller but less relevant pieces by experts working in parallel with, but in isolation from, each other.
