Communicating uncertainty means stating the estimate, its basis, a meaningful limit, and what changes the next action. This pack supplies a harmless delivery dataset, three draft messages, reader teach-backs, and a six-item scoring checklist. The learner repairs misunderstanding rather than chasing reassurance, trust, or persuasion.
This dossier explains the evidence and its limits. It is not a diagnosis, personal recommendation, assessment, clearance, performance promise or training programme. Actionable teaching appears only when the canonical Power record explicitly authorises it.
Complete bounded explanation
What this power means.
Capability to develop or express uncertainty communication in a declared context without inheriting broader claims.
What the current evidence supports
Numeric uncertainty can often be communicated without large trust loss, while wording and cultural context materially affect reception.
How to observe or measure it without overclaiming
Declare uncertainty type, format, source, audience, language, comprehension, trust, decision and equity; trust is not the sole success criterion.
Myth
Use the perfect phrase and everyone will understand risk
Metric
Comprehension, calibrated trust and decision quality for a declared uncertainty message
Boundary
A trusted message is not necessarily understood, accurate, fair or actionable.
Negative and limiting findings
Vague verbal uncertainty could reduce trust.
Effects differed by country, source and topic, and comprehension/decision quality were not always established.
Claims this evidence cannot support
one perfect uncertainty phrase
numbers make communication objective
trust proves understanding
AI can calibrate any message automatically
Evidence guide frame · non-prescriptive
A guide frame—not a training protocol.
Explain how uncertainty format and context affect comprehension and trust without prescribing the perfect message.
What this frame may discuss
Evidence and measurement boundaries for uncertainty communication
Task specificity, access configurations and negative findings
Limits on transfer, efficacy and authority
Conceptual observations
Conceptually compare a numeric range with vague verbal uncertainty in a benign fictional message.
Keep comprehension, calibrated trust, decision quality and equity as separate outcomes.
Reflection prompts
What kind of uncertainty is being communicated?
Could a trusted message still be misunderstood, inaccurate or unfair?
What it cannot establish
A trusted message is not necessarily understood, accurate, fair or actionable.
It cannot establish: one perfect uncertainty phrase.
It cannot establish: numbers make communication objective.
It cannot establish: trust proves understanding.
It cannot establish: AI can calibrate any message automatically.
Accessibility alternatives
Plain language, numbers, frequencies, diagrams, audio and translation are alternative formats.
Cultural context and numeracy access are part of the audience configuration.
No live persuasion target or personal-risk disclosure is needed.
Non-participation remains valid: Yes.
Stop and escalation boundaries
Stop if the frame becomes persuasion, crisis communication, medical consent, political messaging or manipulation testing.
Do not test messages on people without consent and appropriate governance.
Clinical, emergency, legal or public-risk communication requires qualified communicators, affected-person input and accountable review.
Prohibited uses
Live persuasion experiment, audience manipulation, A/B test or optimisation target.
Medical, emergency, legal or political communication protocol.
Claims that one wording guarantees understanding or trust.

BaselineOpen the governed lesson and record its declared baseline before practising.
PractiseFollow the ordered lesson exactly; do not add dose, intensity or claims.
RetestUse the lesson's delayed retention and predeclared transfer checks as separate records.
Maintain or retireKeep only what remains useful inside the evidence and safety boundary.
Authority boundary: A governed step-by-step lesson may be completed independently inside its stated limits. The method is Power-specific; its actionability follows this treatment.
Citation roles are explicit. A source may support existence or trainability while simultaneously limiting transfer, certainty, generalisation or safety.

Current teaching and evidence boundary
The next gate remains visible.
No external confirmation is required for the current bounded explainer and non-prescriptive guide-frame permissions; any stronger efficacy, generalisation, protocol, promotion or independent-validation claim requires a new adjudication.
A separately governed practical lesson is available at /tutorials/pwr-126/. Its safe configuration, prerequisites, ordered practice, measurement, stopping, accessibility, retention, transfer and review rules remain controlling.
