Sherwood Moran’s 1943 Memo: Kindness as Doctrine

In July 1943, Major Sherwood Moran of the US Marine Corps wrote a report for fellow interpreters based on his work interrogating Japanese prisoners in the Pacific. It was not a doctrinal document and had no official status. It has been rediscovered repeatedly ever since, most conspicuously after 2001, and it remains the best short statement of the case for rapport-based interrogation ever written by a practitioner.

Moran's background explains a great deal. He had spent decades in Japan as a missionary. He spoke the language colloquially, understood the culture from the inside, and — the point he insists on most — regarded the prisoner in front of him as a human being with whom he was having a conversation.

The memo's central instruction is that the interrogator's first task is the relationship, and that everything else follows from it. Moran argues against the notion that the interrogator should be dominant, above the prisoner, playing on his fears. He describes sitting on the floor with wounded prisoners, talking about their families, their home prefectures, their units, their health. He recommends knowing enough about Japan that the prisoner recognizes genuine familiarity rather than performed interest. He notes that the sense of being treated as a human being, by an enemy who did not have to, produced in many prisoners a willingness to talk that no pressure could have produced.

He is also clear that this is not softness but technique. The objective is intelligence. The method is chosen because it works.

In modern terms, what Moran was doing was reducing threat vigilance and increasing affiliation, which produces a talkative, elaborative state. And elaboration is the thing an interrogator actually wants, because elaboration is where both the intelligence and the verifiable detail live. A frightened, defensive source produces short, guarded, low-information answers even when they are trying to cooperate.

There is a further point in the memo that anticipates the whole of chapter 105. Japanese soldiers had been told they would be tortured and killed if captured, and many had been prepared to die rather than surrender. Confirming that expectation would have validated the enemy's own propaganda and closed the source. Disconfirming it opened them.

The memo has been rediscovered because its predictions keep replicating. The Alisons' coding of real terrorism interviews in chapter 103, the HIG's research program in chapter 104, and Granhag's Scharff studies all reach the conclusions Moran reached in the field in 1943 with no research literature to draw on.

Which raises the question that makes this chapter worth reading twice. If the effectiveness of rapport over coercion was demonstrable in 1943, well documented by 2013, and correct in the intervening seventy years, then the persistence of coercive methods is not an empirical error. It is something else, and chapter 105 is where that becomes explicit.
