Classify fictional causal claims by design and alternatives
Causal reasoning asks more than whether two variables move together. This pack supplies four fictional cases spanning observation, self-selection, and randomised intervention. The learner names cause and outcome, checks design and time order, generates alternatives, proposes discriminating evidence, and writes a bounded classification. Numerical differences remain descriptive until design supports a causal interpretation.

Classify fictional causal claims by design and alternatives
Causal reasoning asks more than whether two variables move together. This pack supplies four fictional cases spanning observation, self-selection, and randomised intervention. The learner names cause and outcome, checks design and time order, generates alternatives, proposes discriminating evidence, and writes a bounded classification. Numerical differences remain descriptive until design supports a causal interpretation.
Authority and safety
- Use only the fictional cases. Do not accuse a real person, diagnose, generate misinformation, or justify policy, legal, clinical, employment, or financial action.
- A plausible mechanism or diagram does not replace outcome evidence.
- Consequential causal claims require domain experts, suitable study design, affected-person input, and accountable review.
Exact materials
- The four complete fictional case rows
- The causal-workbook columns built into the fixture
- The answer key, hidden until conclusions are recorded
- Paper or an accessible note method
Set up in this order
- Operationally name the proposed cause and measured outcome, then record initial confidence from 0 to 100 before classifying the design.
- Classify the design without upgrading it by wording: observation, self-selection, randomised comparison or another exact label.
- Record at least two compatible alternative explanations and one test whose predicted results would differ between them.
- Classify mechanism as SHOWN, PLAUSIBLE or UNKNOWN. A plausible story is not a measured mechanism.
- Choose unsupported, suggestive, better supported or unresolved; then record final confidence and the exact evidence that moved or preserved it.
- State the boundary and one decision the row cannot support.
Supplied fixture
| Case id | Fictional claim | Design and data | Known context | Learner design | Learner alternatives | Learner discriminating test | Learner bounded conclusion | Learner mechanism status | Confidence before and after review |
|---|---|---|---|---|---|---|---|---|---|
| C1 | Umbrellas make the park path wet. | 30 rainy days average 70 umbrellas and all have wet paths; 30 dry days average 5 umbrellas and none has a wet path. | Observation only; rain status recorded. | [classify] | [two alternatives] | [one test] | [conclude] | [shown / plausible / unknown] | [record both] |
| C2 | A blue greenhouse filter increases seedling height. | 40 matched pots randomly assigned: 20 blue filter, 20 clear; means 18.4 cm and 16.1 cm after four weeks. | Water, soil, and day fixed; one fictional greenhouse. | [classify] | [two alternatives] | [one test] | [conclude] | [shown / plausible / unknown] | [record both] |
| C3 | Using the library quiet room causes readers to finish more pages. | 30 visitors choose quiet room and average 42 pages; 30 choose open room and average 30 pages in the same hour. | Book difficulty and prior habit unmeasured. | [classify] | [two alternatives] | [one test] | [conclude] | [shown / plausible / unknown] | [record both] |
| C4 | A reminder card increases neutral sorting-task completion. | 100 fictional trials randomised: 40/50 complete with reminder, 30/50 without. | Same task, device, criterion, and window. | [classify] | [two alternatives] | [one test] | [conclude] | [shown / plausible / unknown] | [record both] |

Scoring rule
For each case award 1 point for operational variables, time order, correct design, two plausible alternatives, a discriminating test, mechanism status, confidence update and bounded classification: 8 per case, 32 total. Mechanism without measured pathway evidence cannot be called shown. Any move from a fictional row to real blame, diagnosis or policy earns STOP.
Worked example
- For C3 define cause as choosing the quiet room and outcome as pages during the hour.
- Calculate the observed difference: 42-30=12 pages.
- Classify self-selection and list book difficulty and prior reading habit as alternatives.
- Propose accessible random assignment or predeclared measurement of selection factors as discriminating evidence.
- Conclude suggestive association with unresolved causal direction and magnitude.
Correct result: C3 shows a 12-page average association, not proof that the room caused it. Self-selection and unmeasured book difficulty block a strong causal conclusion.
Right and wrong
| Moment | Right / safer | Wrong / riskier | Why |
|---|---|---|---|
| C1 | Treat rain as a common cause. | Perfect association proves umbrellas wet paths. | A measured common cause explains both. |
| C2 | Say better supported in one greenhouse. | The filter works for every plant everywhere. | One setting does not establish universal transfer. |
| C3 | Preserve self-selection. | Rename groups treatment and control. | Wording cannot upgrade allocation. |
| Mechanism | Mark it as hypothesis and seek discriminating outcomes. | An arrow diagram proves cause. | A diagram is not outcome evidence. |
Common mistakes and fixes
| Mistake | Fix |
|---|---|
| Leaving variables vague. | Name exposure, outcome, unit, and time order. |
| Calling every alternative a confounder. | Separate common cause, reverse causation, selection, and measurement error. |
| Proposing more correlation as the only test. | Choose evidence with different predictions under two explanations. |
| Turning a bounded result into blame. | Return to the fictional case and state what further evidence is required. |
Evidence boundary
What the tutorial may—and may not—claim.
Supportable claim
Instruction can reduce selected causal-reasoning errors in science-report interpretation, with short delayed retention.
Measurement boundary
Declare causal question, design, alternatives, confounding, mechanism, uncertainty, data limits and decision context; diagram quality is not causal truth.
See the true cause of anything
MetricAccurate causal classification and alternative-cause generation on novel declared cases
BoundaryA training-task gain cannot certify causality in a complex real system.
Negative and limiting findings
- Evidence remains bounded to science-report and control-of-variables tasks.
- Probe questions without direct instruction did not improve children’s unconfounded experimental reasoning.
- No real policy, clinical or organizational outcome was tested.
Prohibited wording
- see the true cause of anything
- causal training proves expertise
- correlation never matters
- one diagram explains a social system

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.
