Repair a fictional delivery estimate until a reader can teach it back
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.
Authority and safety
Use only the fictional archive-box scenario; do not adapt it to medicine, crisis response, politics, finance, legal advice, or another high-stakes message.
Comprehension is the target. A clear message can still be based on an uncertain or wrong estimate.
The reader may disagree or decline; no persuasion or non-consensual testing is authorised.
Exact materials
The fictional delivery scenario in the fixture caption
A blank baseline-message and teach-back prediction worksheet
The six-item checklist: window, number plus plain language, source, limit, action and change trigger
The uncertainty labels ALEATORY, EPISTEMIC and MIXED
The staged model message and teach-back key, opened only after the learner's baseline and repair are locked
Set up in this order
Read only the scenario caption. Write your own baseline message and one expected reader teach-back before opening the staged key.
Calculate in-window, early and late proportions from all 80 deliveries.
Name the uncertainty: delivery-to-delivery variation is aleatory; uncertainty about whether history still represents the new backlog is epistemic; together the message has mixed uncertainty.
Score your baseline for window, number plus plain language, source, limit, action and change trigger. Preserve the first score.
Compare your expected teach-back with the data. Mark any invented guarantee, missing source, missing variability or missing trigger.
Repair your own message without stronger reassurance and write a second teach-back prediction.
Open the staged model only now. Compare field by field and record what your repair still missed; never rewrite the baseline as if the model had been known.
Supplied fixture
Scenario: of 80 similar deliveries, 56 arrived Tuesday–Thursday, 12 earlier and 12 later. A new carrier backlog may make history less representative. If absent Thursday at 17:00, the fictional coordinator asks for an update. The fixture is blank so the baseline cannot be contaminated by a supplied draft.

Check your work only after you finish
Lock every response first. The checking page is separate so the answers are not exposed inside this exercise.
Award 1 point for each of the six explicit message elements, 1 for a correct MIXED uncertainty classification and 1 for a teach-back that preserves estimate, uncertainty and trigger: 8 total. Baseline and repair remain separate. Opening or copying the staged model before locking the repair invalidates the baseline comparison.
Worked example
Verify M2's number: 56/80=70%, so the arithmetic is correct.
Score M2 at 2/6 for time window and 70%/7-in-10 wording.
Use the teach-back to find guarantee and missing-source errors.
Add 56 of 80, 12 early, 12 late, the backlog limit, current action, and Thursday 17:00 trigger.
Compare the repaired M3 teach-back with every source field.
Correct result: The repaired M3 scores 6/6 and supports accurate teach-back without implying that 70% is certainty.

Why
Numbers and words
70%, about 7 in 10 of 80.
Probably soon.
Vague wording hides range and reference class.
Limitation

Eighty cases make it certain.
Changed conditions remain important.
Comprehension
Ask for estimate-limit-trigger teach-back.
Ask whether it feels trustworthy.
Trust does not prove understanding.
Action
No action now; update if absent at the trigger.
Wait indefinitely because 70% reassures.
A usable message includes a change condition.

Evidence boundary
What the tutorial may—and may not—claim.
Supportable claim
Numeric uncertainty can often be communicated without large trust loss, while wording and cultural context materially affect reception.
Measurement boundary
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.

Step-by-step learner mode
Each activity includes its success check, a nearby accessible alternative and an “I’m stuck” correction path. Alternatives preserve the target where possible; when they change the task, Titan labels them as related rather than equivalent.
01
Read only the scenario caption
Read only the scenario caption. Write your own baseline message and one expected reader teach-back before opening the staged key.
Why this step exists
“Read only the scenario caption” creates the auditable value, condition or statement needed for the tutorial’s later comparison and conclusion.
Success check
A legible entry directly completes “Read only the scenario caption” and records the requested condition, decision or boundary without adding a new claim.
I’m stuck on this step
Reset: Re-read this authored instruction — “Read only the scenario caption. Write your own baseline message and one expected reader teach-back before opening the staged key.” — and its success check, then attempt only this step.
Possible snag: Treating silence as comprehension.
Correction: Use the supplied teach-back checklist.
Stop / get help: A governed step-by-step lesson may be completed independently inside its stated limits. Stop if the declared configuration cannot be maintained, uncertainty becomes material, adverse effects appear, or qualified authority is required.
02
Calculate in-window, early and late proportions from all 80 deliveries
Calculate in-window, early and late proportions from all 80 deliveries.
Why this step exists
“Calculate in-window, early and late proportions from all 80 deliveries” creates the auditable value, condition or statement needed for the tutorial’s later comparison and conclusion.
Success check
The work shows the value requested by “Calculate in-window, early and late proportions from all 80 deliveries”, retains the supplied units or signs and leaves any unsupported value unknown.
I’m stuck on this step
Reset: Re-read this authored instruction — “Calculate in-window, early and late proportions from all 80 deliveries.” — and its success check, then attempt only this step.
Possible snag: The result from “Calculate in-window, early and late proportions from all 80 deliveries.” does not yet meet this declared check: The work shows the value requested by “Calculate in-window, early and late proportions from all 80 deliveries”, retains the supplied units or signs and leaves any unsupported value unknown.
Correction: Return to the start of “Calculate in-window, early and late proportions from all 80 deliveries”, reduce complexity or pace, and repeat only the part needed to satisfy: “The work shows the value requested by “Calculate in-window, early and late proportions from all 80 deliveries”, retains the supplied units or signs and leaves any unsupported value unknown.”
Stop / get help: A governed step-by-step lesson may be completed independently inside its stated limits. Stop if the declared configuration cannot be maintained, uncertainty becomes material, adverse effects appear, or qualified authority is required.
03
Name the uncertainty: delivery-to-delivery variation is aleatory
Name the uncertainty: delivery-to-delivery variation is aleatory; uncertainty about whether history still represents the new backlog is epistemic; together the message has mixed uncertainty.
Why this step exists
“Name the uncertainty: delivery-to-delivery variation is aleatory” establishes the exact Uncertainty communication question or boundary that every later comparison must preserve.
Success check
Evidence of completion shows the learner followed this exact instruction without adding an unstated step: “Name the uncertainty: delivery-to-delivery variation is aleatory; uncertainty about whether history still represents the new backlog is epistemic; together the message has mixed uncertainty.”
I’m stuck on this step
Reset: Re-read this authored instruction — “Name the uncertainty: delivery-to-delivery variation is aleatory; uncertainty about whether history still represents the new backlog is epistemic; together the message has mixed uncertainty.” — and its success check, then attempt only this step.
Possible snag: Percentage without denominator.
Correction: Add 56 of 80 and about 7 in 10.
Possible snag: Hiding changed conditions.
Correction: Name the new backlog.
Stop / get help: A governed step-by-step lesson may be completed independently inside its stated limits. Stop if the declared configuration cannot be maintained, uncertainty becomes material, adverse effects appear, or qualified authority is required.
04
Score your baseline for window, number plus plain language, source, limit, action…
Score your baseline for window, number plus plain language, source, limit, action and change trigger. Preserve the first score.
Why this step exists
“Score your baseline for window, number plus plain language, source, limit, action and change trigger” creates the auditable value, condition or statement needed for the tutorial’s later comparison and conclusion.
Success check
The work shows the value requested by “Score your baseline for window, number plus plain language, source, limit, action and change trigger”, retains the supplied units or signs and leaves any unsupported value unknown.
I’m stuck on this step
Reset: Re-read this authored instruction — “Score your baseline for window, number plus plain language, source, limit, action and change trigger. Preserve the first score.” — and its success check, then attempt only this step.
Possible snag: The result from “Score your baseline for window, number plus plain language, source, limit, action and change trigger. Preserve the first score.” does not yet meet this declared check: The work shows the value requested by “Score your baseline for window, number plus plain language, source, limit, action and change trigger”, retains the supplied units or signs and leaves any unsupported value unknown.
Correction: Return to the start of “Score your baseline for window, number plus plain language, source, limit, action…”, reduce complexity or pace, and repeat only the part needed to satisfy: “The work shows the value requested by “Score your baseline for window, number plus plain language, source, limit, action and change trigger”, retains the supplied units or signs and leaves any unsupported value unknown.”
Stop / get help: A governed step-by-step lesson may be completed independently inside its stated limits. Stop if the declared configuration cannot be maintained, uncertainty becomes material, adverse effects appear, or qualified authority is required.
05
Compare your expected teach-back with the data
Compare your expected teach-back with the data. Mark any invented guarantee, missing source, missing variability or missing trigger.
Why this step exists
“Compare your expected teach-back with the data” isolates the named evidence distinction so the learner can interpret Uncertainty communication without extending the claim.
Success check
The output directly answers “Compare your expected teach-back with the data”, names the relevant distinction and stays within the supplied record.
I’m stuck on this step
Reset: Re-read this authored instruction — “Compare your expected teach-back with the data. Mark any invented guarantee, missing source, missing variability or missing trigger.” — and its success check, then attempt only this step.
Possible snag: Repairing with stronger reassurance.
Correction: Rewrite the missing estimate, source, limit, or trigger.
Stop / get help: A governed step-by-step lesson may be completed independently inside its stated limits. Stop if the declared configuration cannot be maintained, uncertainty becomes material, adverse effects appear, or qualified authority is required.
06
