CIA founding

The CIA’s founding in 1947 was an attempt to answer a problem exposed by Pearl Harbor: intelligence gathered across separate military services could fail to become a shared understanding of danger. The agency embodied a postwar conviction that unity of intelligence could protect the United States from surprise. The book’s larger argument complicates that answer: central authority may connect scattered information, but it can also sacrifice the independence and specialized knowledge that make a dispersed system intelligent in the first place.

The case for a central agency

In April 1946, General Wild Bill Donovan addressed a forum organized by the New York Herald-Tribune in a speech titled “Our Foreign Policy Needs a Central Intelligence Agency.” During World War II, Donovan had led the Office of Strategic Services, the United States’ chief wartime intelligence organization. After the war, he became a prominent advocate for a more powerful peacetime successor.

Before the war, intelligence-gathering responsibilities were divided among the military services. Their failure to anticipate the attack on Pearl Harbor, despite evidence that in retrospect appeared ample, exposed the limitations of that arrangement. Donovan also pointed to the possibility of conflict with the Soviet Union and to technologies that made national borders seem less secure: “the rocket, the atomic bomb, bacteriological warfare.” His proposed remedy was “a centralized, impartial, independent agency” responsible for the country’s intelligence operations.

Donovan’s advocacy damaged his own prospects. His sharp criticism alienated members of the intelligence community and probably ended his chances of returning to government service. The institutional result, however, followed the direction he had urged: in 1947, Congress passed the National Security Act and created the CIA. As historian Michael Warner characterized the law’s purpose, it was to “implement the principles of unity of command and unity of intelligence.” The founding thus translated a diagnosis of fragmented authority into a national institution.

A founding argument revisited

The book returns to Donovan’s campaign when considering the intelligence failures preceding September 11. Congress’s post-attack critique stressed a lack of information sharing among agencies. Instead of producing a coherent picture of threats, the agencies held localized snapshots. Senator Richard Shelby argued that the FBI’s decentralized organizational structure had left information fragmented into largely independent fiefdoms, and called for an agency positioned above and independent from disputatious bureaucracies. His prescription revived the centralizing logic associated with Donovan: fragmentation had led the country astray, so centralization might set it right.

The argument was not simply that every attack could have been predicted. The book distinguishes prediction of the specific attacks from the possibility of recognizing the collective significance of available information or producing a concrete estimate of the likelihood of an attack. On that view, better processes might have improved the chance of seeing relationships among pieces of evidence even if they could not have disclosed exactly what would happen.

But the book rejects the inference that decentralization itself was the cause. Dividing work among agencies can foster specialization, finer-grained analysis, and diversity of perspective. Information dismissed as noise by one group of analysts may reveal a clue or relationship when examined by another. The failure lay in having separate sources of expertise without an effective way to combine their information and judgments. In the book’s formulation, the intelligence community had decentralization without aggregation—and therefore lacked an organization capable of turning its distributed knowledge into collective understanding.

Information without a single center

Shelby’s proposal would make it easier for one agency to take charge of information, but, the book argues, it would also risk losing the benefits of independence, diversity, and local knowledge. The alternative is not to keep information isolated. It is to create ways to share and aggregate it without requiring a small group at the center to decide what matters. A simple technical step illustrates the gap: two years after September 11, the government still lacked a single unified watch list drawing on data from all parts of the intelligence community. Linking agency databases could have improved information flow while leaving the agencies autonomous.

This tension defines decentralization more broadly. People close to a problem may possess tacit knowledge tied to a particular place, job, or experience—knowledge that is valuable but difficult to summarize and transmit. Decentralized arrangements can encourage individuals to specialize and acquire that local understanding, increasing the information available across a system. Their weakness is that information uncovered in one part may never reach another. The institutional task is to make local knowledge collectively useful without stripping away the circumstances that make it specific.

The CIA’s founding therefore remains significant in two directions at once. It marks the force of the postwar demand for unity after divided responsibilities failed to produce warning. It also frames the book’s broader distinction between centralization and aggregation: coordinating information need not mean concentrating every judgment in a single authority. A capable system must connect dispersed knowledge while preserving the independent perspectives that allow it to become more than one official view.
