Review a message from start to finish
Information judgment · Lesson 6: An integrated information review
Estimated time: 25–30 minutes. Suggested preparation: lessons one to five.
Teaching note: All organizations, messages, dates and figures are fictional. Work within the packet; do not search for real organizations. Confirmation is limited to the supplied materials.
What you will learn
- Combine claims, emotion, sources, numbers and reasoning in one record.
- Assess support for individual claims.
- Write an accurate shareable summary and choose a next action.
- Revise your judgment when new material appears and explain why.
1. A message worth sharing?
Document A · Social post · May 12, 2025: New training doubles participants' pass rate! Three outlets confirm that everyone benefits. Enroll or fall behind. Today is your last chance—share with friends now!
Decide whether to share the message or recommend enrollment, not whether you can prove the course effective or ineffective. Record your initial judgment, claims to check and material you want most. Revisit this after the lesson.
2. Read the complete packet
Document B · News excerpt · May 11: The Morning Bridge project reports a pilot in which training completers' pass rate rose from 40% to 80%. This article cites the project's May 10 statement. Two other articles also cite only that statement and provide no independent testing.
Document C · Project statement · May 10: One hundred people volunteered; fifty completed training and both tests. Among those fifty, twenty passed the pre-test and forty passed the post-test, using the same test standard. The other fifty have no post-test records. There was no comparison group, so results alone cannot establish a causal training effect. The course provider conducted the project.
Document D · Enrollment rules · May 10: The current cohort closes on May 12; the next cohort is planned for June. This notice supplies no price, refund details or guarantee of individual suitability.
A promotes, B reports, C describes results and limitations, and D states enrollment rules. C is the original statement, but this exercise does not independently verify its underlying data.
3. Build a claim list
Separate A into claims: the pass rate doubled; three outlets confirm it; everyone benefits; non-enrollees fall behind; today is the last chance; immediate sharing is warranted.
“Last chance” could mean this cohort or imply no later enrollment. Interpret it against the rules rather than choosing only the convenient meaning.
Be specific about emotion: “fall behind” applies pressure; “now” urges circulation. Pressure does not prove ineffectiveness, and a genuine deadline does not establish value.
4. Check citations and numbers
The chain is A → B → C, with the other articles returning to C too. There are not three independent tests. D is additional material about timing, not evidence of effectiveness.
Completers' pre-test rate is 20/50 = 40%; their post-test rate is 40/50 = 80%. The absolute increase is 40 percentage points; the relative increase is (80% − 40%)/40% = 100%. “Doubled” fits this definition.
Across all enrollees, 40/100 = 40% have recorded post-test passes. Missing non-completers cannot simply be counted as known failures. Pass counts also do not reveal each person's score change or show that everyone improved.
5. Different claims deserve different conclusions
The packet supports a doubled rate among completers. “Everyone benefits” exceeds the sample and data. Independent confirmation by three outlets is inconsistent with the citation chain. D supports today's current-cohort deadline, not a permanent end to opportunities.
Causation remains unresolved: practice, other learning or selection could affect results. Naming these possibilities does not establish them as causes.
Actions can differ: decline to circulate the overclaim, yet share an accurate summary with an interested friend and suggest checking content, cost and refund terms. You can also withhold a recommendation, explaining the decision-relevant reasons.
6. Task one: write your review
Using A–D, examine at least three key claims; identify emotional pressure and the call to action; map citations; calculate absolute and relative change; identify a reasoning gap and a further check.
Work independently before opening the explanation. Different wording is acceptable when judgments trace back to material.
Explore the answer and explanation
Explanation
A complete response can assess what doubled, whether coverage independently corroborates the result, and whether today's deadline means no future opportunity. “Enroll or fall behind” applies pressure; “share with friends now” is the call to action.
The citation map should identify a shared source. Calculations should include 40% to 80%, 40 percentage points and 100% relative growth, explicitly referring to fifty completers.
Gaps include no comparison group, missing post-tests for non-completers and no individual-effect data. Seek test methods, participant follow-up or course terms, explaining which judgment each check would inform.
7. Task two: write a shareable version
Write an 80–130-word summary for a friend, then separately state whether you recommend enrollment and why. Do not turn unproven effectiveness into proven fraud or retain unsupported universal promises.
Explore the answer and explanation
Explanation
“The project reports that fifty of one hundred enrollees completed training. Among completers, pre- and post-test pass rates were 40% and 80%, a forty-percentage-point increase. There was no comparison group and no post-test data for non-completers, so this alone cannot establish a training effect or guarantee universal benefit. Three articles cite the same statement. Today is the deadline for the current cohort; another is planned for June.”
A separate recommendation might be: “I would not recommend purchasing on this evidence alone. Check content, price and refund arrangements, then compare alternatives against your goals.” Other decisions can be reasonable; assess evidence and reasoning, not the purchase choice itself.
8. Task three: update when evidence changes
Document E · Correction · May 13: The project identifies duplicate entries. The correct post-test pass count among completers is thirty-five, not forty. The pre-test count remains twenty and the completer count fifty. Other limitations remain unchanged.
Recalculate rates and changes. Revise your summary. Which judgments change and which remain? If you already shared the earlier version, how would you correct it?
Explore the answer and explanation
Explanation
The post-test rate is 35/50 = 70%, compared with 40% initially: a thirty-percentage-point increase and 75% relative growth. Across all enrollees, 35% have recorded post-test passes. “Doubled” no longer fits the revised figures.
No comparison group, missing non-completer data and shared news sourcing remain limitations. A correction does not prove ineffectiveness; a remaining increase does not justify ignoring the correction.
A correction message: “On May 13, the project revised post-test passes to thirty-five. Completers' rates went from 40% to 70%, not the previously reported doubling. The limitations concerning the comparison group and missing data still apply.” Update your record, date the correction and notify the original recipients.
9. Review the process, not just the verdict
Revise any missing part. Checkboxes are for self-review, not automated grading or certification. Explaining a revision matters more than defending an initial judgment.
10. Save your final review
You have reached the end of this six-lesson introductory path. Try reviewing a low-stakes public message independently using this record. If material cannot be found, retain uncertainty rather than forcing a verdict. Do not include private identifying information in your learning notes.
