Based on the provided sources, the detection of “weak signals” or outliers in complex situations is neither solely a property of individual sensory capability nor purely an artifact of structural framing; rather, it is an emergent property of the interaction between an observer’s Questioning Insight (Q) and the specific “station points” or logistics chosen to frame the inquiry.

Revans suggests that detection is governed by the following dynamics:

1. Individual Capability: The Filter of the “Cortical Slate”

The individual’s ability to detect outliers is often hindered by their own internal programming.

• The Problem of P: Traditional expertise and “Programmed Knowledge” (P) act as a filter that directs attention to the “certainties of the elapsed past” rather than fresh signals[1][2]. Revans warns that the “idolisation of past experience” can permanently obscure a manager’s perception, making them unable to see anything in the present other than a confirmation of the past[3][4].

• The Right Hemisphere: Revans notes that while all observers may see the same “details” (left brain), the right hemisphere interprets the “pattern” or melody[5]. Detection of a new signal is often a “reinterpretation of many facts already there” rather than the discovery of new data[6].

• Admission of Ignorance: Individual sensory capability begins with the moral quality of honesty[7][8]. A leader must be “more interested in what they cannot see than in what is known” to detect signals in the “microcosm of uncertainty”[2][9].

2. The “Net” of Station Points: Logistic Framing

Revans places immense importance on the “station points”—the physical and professional context from which the observer looks.

• Unfamiliar Settings: The sources state that a manager’s perception is transformed by moving into “unfamiliar surroundings or unfamiliar tasks”[10]. By “deserting their own field of professional competence,” an observer is obliged to work from first principles and question “unconscious assumptions” that were invisible in a familiar setting[11].

• The Logistics of Inquiry: Revans identifies four specific “exchange options” (e.g., a familiar task in an unfamiliar setting)[10][12]. These logistical choices function as the “net” that determines which signals are caught; for instance, working away from home forces an observer to rigorously verify facts that they would have taken for granted in their own department[13][14].

3. Emergence through the “Set” and the “Random”

The detection of outliers is ultimately an emergent artifact of the Action Learning Set, which acts as a social “net.”

• The Set as a Mirror: The Set (a group of 4-6 peers) functions as a “looking glass” or mirror[15][16]. It helps the observer catch “weak signals” about their own behavior or assumptions that they are “barely aware of and find difficult to own”[17][18].

• Exploiting the Random: Revans describes Action Learning as the “exploitation of the random”[19]. The “Set” encourages the “trial and error rearrangement of detail” to form fresh ideas, much like a composer rearranging musical themes[19][20].

• Boundary Judgments: The “net” is also defined by the Diagnostic Questions (“What are we really trying to do?“)[21][22]. These questions establish the boundary judgments of the inquiry, narrowing the “confusion or the anxiety” so the observer can identify the right signals to act upon[23].

Summary

Detection is an emergent artifact of “System Gamma”—the unique learning process of the individual—when it is subjected to the “System Beta” cycle of action and the critical mirroring of a Set[24][25]. As Revans notes, “there is no general theory of search” because if you do not know what you are looking for, you cannot sample your experience; therefore, detection requires Q (Questioning Insight) to be the “senior partner” to the “net” of P[1][26].
