Communication & Persuasion

Effective communication structures information around the audience's question, not the author's knowledge. Lead with the conclusion so the reader grasps the argument before deciding how deeply to inspect.

This is the smallest domain by note count (~10 notes) and likely has gaps in coverage. The watching seed diagram-as-audience-communication-design captures the most promising emerging cluster.

Structure and sequence

Conclusion first communication (Minto Pyramid Principle) - Lead with the conclusion, then provide the supporting argument. Most writing does the opposite (building to the conclusion) because that is the order in which the author thought about it - but the reader wants to know the answer first so they can decide how much of the supporting argument to read. The pyramid structure: answer → key arguments → supporting data.

Concrete abstract concrete - The C-A-C pattern: start with a concrete case, abstract to the general principle it illustrates, return to a concrete application. The first concrete case provides a handle; the abstract principle provides the transferable claim; the second concrete case proves the principle is operational. This is the teaching structure, as opposed to the reporting structure (A-C-C) or the discovery structure (C-C-A).

Dtwi communication structure - “Don’t Tell Me What I Already Know” - the communication failure of restating context the audience already has before reaching the new information. The fix: open by marking where you are in the shared map (“you already know X, here is what you didn’t know”) rather than rebuilding the map from scratch for an audience that already has it.

Framing and meaning

Insight as named need - An insight is a named, specific human need that has not been solved. The naming is the move: giving a need a name makes it legible, memorable, and designable for. Most “insights” are observations; the discipline is to find the underlying named need that the observation points at.

Naming tactic breaks the spell - Naming a manipulation tactic (social pressure, urgency, scarcity) breaks its power because it makes the implicit explicit. The audience can no longer be moved by a tactic they can see operating. This is a defensive communication principle, but it also has an offensive corollary: tactics that can’t withstand being named are manipulation, not persuasion.

Semiology expression precedes evaluation - Semiological discipline: before evaluating a claim (true/false, good/bad), first understand what it expresses - what relationship between signifier and signified it asserts. Evaluation of an expression whose meaning you haven’t grasped is noise. This is the communication-theory form of the scout mindset principle.

Leadership communication as meaning making - (Cross-listed from Organisation) Leadership communication is primarily meaning-making, not information transmission. Facts without interpretation leave the meaning to be filled in by rumour and anxiety. The discipline: always pair facts with interpretation - “here is what is happening and here is what it means for us.”

Design and audience

Conclusion first communication + watching seed diagram-as-audience-communication-design - The watching seed adds a second dimension: technical artefacts (diagrams, documentation, specifications) should be designed around the audience’s question. The same underlying system requires different representations for different readers. A system architecture diagram for the CEO, the engineering team, and the new hire are three different artefacts serving three different questions.

Parallel thinking mode separation (de Bono / Six Thinking Hats) - Creative and evaluative thinking are incompatible cognitive modes. Mixing them (generating and criticising simultaneously) produces less of both. The Six Thinking Hats technique separates these modes explicitly and sequentially, which allows full creative generation before any evaluation, and full evaluation once the creative set is complete.

Information hierarchy serves reader context + Chunking up down - The same audience-design principle stated from the UX-content direction: organise the information hierarchy around the user’s context and immediate question, not the product’s internal structure. Lead with the outcome for orientation, then reveal only the next necessary layer (concrete bottom → grouped middle → abstract top), and use chunking up/down to move deliberately between those altitudes. This is a fourth independent corroboration of the watching diagram-as-audience-communication-design seed.

Persuasion

Hpm conversational offer - High-Probability Messages are offers shaped around what the audience is already motivated to hear, not arguments for what the speaker wants to say. The discipline is to start from the audience’s existing concerns and link your message to those concerns - not to present your argument and expect the audience to adopt it.

Design vs manipulation intent alignment + Ten principles of influence - Influence levers are value-neutral means: the same technique (reciprocity, manufactured progress, urgency) is design when it serves the other person’s own goals with transparent intent, and manipulation when it serves only yours - and awareness is not the safeguard people assume, since these levers work whether or not the target notices. The ten-principles taxonomy is held as a defensive lens for recognising adversarial influence, not as a playbook.

Concrete abstract concrete - (See above) The C-A-C pattern is also a persuasion structure: the first concrete case earns attention, the abstract principle earns agreement, the second concrete case proves applicability.

Open gaps

This domain has sparser coverage than others. Areas where additional notes would strengthen it:

Rhetoric and argumentation - the vault has the cognitive science (Hats, C-A-C) but not the classical rhetoric framework (ethos, pathos, logos; the five canons)
Listening - Listening to reality is the closest note, but it’s epistemological rather than communicative
Writing specifically - Almost done as distinct failure mode touches on writing process but more coverage would help
Negotiation - there are 3 negotiation notes (BATNA, interest vs. position, ethics test) that could sit here or in Strategy

Connecting to other domains

→ Organisation: Leadership communication as meaning making is both a communication and an organisation principle. Communication design is a management competence.
→ Epistemology: Semiology expression precedes evaluation is directly epistemological - understand before judging. Conclusion first communication presupposes that the author has already gone through the discovery process and is now reporting results; communication structure is downstream of epistemic work.
→ Product & Design: Insight as named need is the output of discovery work - it is the form in which product insight should be expressed before translating to specification.
→ Personal Development: Communication is a character property in part - the scout mindset applies to communication as much as to belief formation. Effective communication requires the same orientation to the audience as the epistemic virtues require toward evidence.
