2.1Signals among noise
Wohlstetter's Pearl Harbor: Warning and Decision (1962) concerns the attack on Pearl Harbor. Its claim, as the study's note gives it, is that the signals of the attack were present beforehand but buried among irrelevant and misleading ones, which the book calls noise, and that the failure was in telling signal from noise and acting on it, not in the absence of information.
Two things in that note matter here. The first is the denial that information was lacking. The failure was not that the decisive fact was missing from the files; it was that the decisive fact sat beside many others that pointed elsewhere or nowhere. The second is that the note joins two operations in one clause: telling signal from noise, and acting on it. The weight, as read here, falls on the first. A signal that cannot be distinguished cannot be acted on, so on this account the act of discrimination is the place where warning fails first.
A further point is the article's, not the note's: the distinction between signal and noise can only be drawn after the event. A signal is a message that turns out to have pointed to it; before the event, the receiver sees only messages and must weigh them.
2.2Warnings not believed, or not acted on in time
Betts's Surprise Attack: Lessons for Defense Planning (1982) claims, in the study's note, that surprise attacks have usually succeeded not for want of warning but because warnings were not believed, or not acted on in time, and that the obstacles are political and organisational as much as a lack of information.
The note shares Wohlstetter's starting point: warning was usually there. Where it differs is in where it places the obstacle. Wohlstetter's note places it in discrimination; Betts's places it in belief and in timely action, and names the obstacles to these as political and organisational. On this account a warning can be distinguished from noise and recognised for what it is, and still not be believed or acted on in time.
The difference matters for what follows from it, though the notes themselves do not draw the consequence. If the main obstacle were discrimination, one would look for remedies in collection and analysis; if it were belief and action, one would look to how decisions are made: who must be persuaded, who may act, and what acting on a warning that may prove false costs them. That inference is this article's.
2.3The receiving mind and the group around it
Jervis's Perception and Misperception in International Politics (1976), as the note gives it, holds that decision-makers fit new information to what they already believe, and misread others' intentions. The mechanism serves either side: a receiver who fits messages to a prior expectation may hear as noise what does not fit, or may distinguish the signal and still disbelieve it.
Janis's Victims of Groupthink (1972) concerns groups. Its claim, in the note, is that cohesive policy groups under pressure come to seek agreement over a realistic appraisal of alternatives, which Janis calls groupthink, suppressing doubts, as in the Bay of Pigs decision; and that remedies include assigning a critical evaluator and inviting outside experts. A warning that contradicts a group's shared expectation must be voiced by someone; a critical evaluator assigned in advance gives that contrary voice a place before it is needed.
2.4Whose loss, and how much weight for the bad prognosis
Luhmann's Risk: A Sociological Theory (1993), in the study's note, separates risk, a possible loss attributed to one's own decision, from danger, a possible loss attributed to something outside one's control; the same loss is a risk to the one who decides and a danger to those who are affected but did not decide. Applied to warning, the receiver who decides not to act takes a risk; those who would suffer the warned-of harm, and had no say, face a danger.
Jonas's The Imperative of Responsibility (1984) argues, in the note, that technological power reaches so far into the future that ethics must take responsibility for future generations, and proposes giving the bad prognosis priority over the good, which Jonas calls a heuristics of fear, where the stakes are irreversible. A warning is a bad prognosis, so the rule speaks directly to credence, which Wohlstetter's and Betts's notes describe but do not prescribe for.
2.5Signals agreed in advance, and the sorting of what is known
Schelling's The Strategy of Conflict (1960) is noted for two ideas: focal points that let parties coordinate without talking, and commitments that bind the one who makes them. The note concerns bargaining, not warning, and the application here is this article's own. A signal whose meaning both ends settled before it was sent (a fire on a hill means that a city has fallen) resembles, by analogy, the coordination Schelling's focal points make possible; and a message that cannot be recalled once sent resembles a commitment in that it constrains the one who sent it, a problem that will return in the second record.
Neustadt and May's Thinking in Time (1986) holds, in the note, that decision-makers misuse history, above all by seizing on one analogy, and recommends separating what is known, unclear and presumed, asking how the present situation came about, and seeing the issue as part of a stream of time running from the past into the future. That sorting is the operation a warning forces on its receiver.
Collingridge's The Social Control of Technology (1980) states, in its note, the dilemma of control: while a technology is young its effects cannot be known, and once they are known it is entrenched and hard to change. Collingridge argues for keeping decisions corrigible, easy to monitor and to correct, and for keeping options open. His subject is technology, not warning.
2.6The positions side by side
The two central notes agree that warning is usually present. They disagree on whether the decisive obstacle lies before the moment of recognition (Wohlstetter's discrimination of signal from noise) or after it (Betts's belief and timely action, with political and organisational obstacles). On the inference drawn in 2.2, which is not the notes', the remedies would differ accordingly: better collection and analysis on one side; on the other, changes in who must be persuaded and how decisions are taken. Jervis's and Janis's notes describe mechanisms that can operate at either station; Luhmann's, Jonas's and Neustadt and May's offer distinctions or rules that bear on how a warning is weighed and who bears its loss.
2.7What the debate leaves joined
Both central notes treat belief and action together. Betts's note names them as a pair (not believed, or not acted on in time), and Wohlstetter's ends with acting on the signal. Neither note asks, as a separate matter, who is entitled to act on a warning once it has been received and believed, and what happens when the believer and the actor are different people.
That separate matter is what this article calls standing. Someone can receive a warning without doubt, believe it, and still lack the standing to act: because the act belongs to an office they do not hold, because acting requires others' consent, or because they are a captive in a house where no one will take their word. The Agamemnon, read in Section 6, gives the clearest picture of standing failing after belief has partly formed. The records, read in Sections 4 and 5, write standing out in detail. Separating it from credence is the article's proposal, offered as an addition to the debate rather than a resolution of it.
