How does superintelligence work when an AI must make a long document shorter without changing what it means? A school notice may describe a free event that anyone can enter, alongside a separate workshop that requires registration. If a summary says “Everyone must register”, it is concise but wrong. The problem is not the length of the output; it is the condition that disappeared.
The mechanism is information-preserving summarisation. A useful AI summary selects facts relevant to the reader while retaining their essential scope, dates, quantities, exceptions and source attribution. Compression inevitably leaves some words out, but it should not silently turn optional instructions into requirements, a capacity into confirmed availability, or a planned event into something that already happened.
This practical guide uses a completely fictional Cedar Reading Fair notice with sixteen source facts, examples of weak and accurate summaries, and twenty-eight checkable statements. We also show how teachers and AI builders can audit omissions and invented claims. The event, rules and scores are educational inventions, not real public announcements or model benchmarks. “How Superintelligence Works” is the name of a learning series, not a claim that current AI systems have attained artificial superintelligence.
Quick facts: what a trustworthy summary keeps
- The exact event or subject, not merely a similar-sounding topic.
- Dates, time ranges and time-zone qualifications where they matter.
- Who must act, who may act and who is exempt.
- Words such as must, may, only, unless, before and optional.
- Numbers with their roles: capacity, price, availability or measured result.
- Source uncertainty, especially when an event is only planned.
- No invented confirmation, participant list or completed action.
1. Summarising is not copying everything
A summary takes a larger source and produces a shorter representation of its important information. It can combine related sentences, simplify language and omit details that the reader does not need for the current task.
But shortening is not the same as rewriting the facts. If a source gives a limited audience for a workshop, removing the audience qualification can produce a different and potentially misleading rule.
2. Every summary has a purpose
A parent checking whether a child needs to register may care most about eligibility, deadline and required materials. A visitor checking where to arrive may need the general entry time and location.
The best summary depends on that purpose. An assistant should preserve facts relevant to the requested decision and avoid pretending a one-sentence description can serve every possible reader equally well.
3. A summary is a transformation of claims
The source contains statements about the world or about a planned event. A trustworthy summary transforms their wording while keeping their meanings aligned with the original statements.
An AI can introduce a misleading claim even when it quotes the same number. For example, “maximum twenty participants” does not mean “twenty places remain available”. The number is preserved, but its role has changed.
4. Scope is one of the most fragile details
Suppose a notice says “Workshop participants must bring a pencil.” That requirement applies to people taking part in the workshop, not necessarily every person entering the wider fair.
A summary saying “Everyone must bring a pencil” has expanded the rule. The model must keep the specified group attached to its instruction rather than moving it to the broader event.
5. Optional is not required
“Visitors may bring a water bottle” permits the item. “Visitors must bring a water bottle” imposes an obligation. The difference is a change of meaning, not a minor style choice.
An assistant that replaces may with must can create unnecessary preparation, confusion or exclusion. Modal verbs are part of the factual content that a faithful summary must protect.
6. A date without a role can mislead
A notice may contain both the event date and an earlier registration deadline. Putting the right date beside the wrong label produces a false instruction even if both dates were copied accurately.
A responsible summary identifies which date belongs to the public event and which governs sign-up for the workshop. It must not treat all dates in a notice as interchangeable.
7. The fictional Cedar Reading Fair
Imagine an entirely invented school notice for a Reading Fair on Saturday, 14 November 2026. The fair itself is open without advance registration, but an additional educational workshop has stricter conditions.
We assume the notice is complete for the listed facts and uses Singapore local time. The scenario is fictional, so the summary must not imply that the event exists at a real school or that attendance and bookings have been confirmed.
8. The complete source-fact ledger
- F01 — Event: fictional Cedar Reading Fair.
- F02 — Event date: Saturday, 14 November 2026.
- F03 — General fair time: 10:00–12:00, Singapore local time.
- F04 — General fair venue: fictional Cedar School Hall.
- F05 — General admission is free.
- F06 — General visitors do not need advance registration.
- F07 — Optional activity name: Story Builders workshop.
- F08 — Workshop is for Primary 5 and Primary 6 pupils only.
- F09 — Workshop time: 10:30–11:15, Singapore local time.
- F10 — Workshop venue: Room B.
- F11 — Advance registration is required for the workshop.
- F12 — Workshop registration closes at 17:00 on 10 November 2026.
- F13 — Workshop capacity is at most twenty registered participants.
- F14 — Workshop participation has no fee.
- F15 — Workshop participants must bring a pencil.
- F16 — Bringing a water bottle is optional; no remaining-seat or attendance information is provided.
9. Identify the two different activities
The fair and the workshop are related, but they are not identical. General fair entry takes place in the school hall from 10:00 to 12:00. The Story Builders workshop takes place in Room B from 10:30 to 11:15.
These time periods overlap, and that is not necessarily an administrative conflict because they refer to different activities and locations. A summary should not erase the separate roles of the fair and its workshop.
10. Separate general admission from workshop admission
General admission is free and does not require advance registration. Workshop participation is also free but does require advance registration. The word free does not mean registration is unnecessary for every part of the programme.
An AI may be tempted to compress the rules into “Free event, no registration”. That would be incomplete for a reader specifically seeking a workshop place. The summary needs to preserve the exception relevant to that reader.
11. The registration deadline belongs to the workshop
The fictional notice closes workshop registration at 17:00 on 10 November 2026. The public event itself takes place on 14 November. These are distinct timestamps with different purposes.
A careless summary might say “Fair registration closes on 10 November”, making it sound as though general visitors must register. That would change the admission policy. The deadline should remain attached to the workshop.
12. The workshop has a narrower audience
The Story Builders session is for Primary 5 and Primary 6 pupils only under the fictional source. General fair entry is not restricted by that specific workshop condition.
An assistant that writes “The Reading Fair is only for Primary 5 and 6 pupils” has improperly applied the workshop’s audience boundary to the entire event. The difference matters for readers deciding whether to visit.
13. Why the location matters
The hall is the stated venue for general fair attendance. Room B is the stated location of the separate workshop. Both are named places in the same fictional school.
An AI that says every visitor should arrive at Room B has moved the workshop venue into the general instructions. Copying a location word correctly is not enough if the event it belongs to has changed.
14. A duration should be calculated from the right interval
The fair runs from 10:00 to 12:00, a two-hour interval. The workshop runs from 10:30 to 11:15, which is forty-five minutes.
Reporting a two-hour workshop would confuse the general event duration with the smaller session. The source times support precise arithmetic only when the correct activity labels are preserved.
15. A capacity is not available inventory
The source specifies that the workshop can have at most twenty registered participants. It does not say how many places have already been taken or whether any seats are still available.
An AI should not write “Twenty seats available now” or “All twenty spaces are booked.” Those are different factual claims requiring a real booking record. Capacity alone cannot establish remaining availability.
16. No fee is different from confirmed registration
The workshop has no participation fee under the fictional notice. A pupil may still need to complete the required registration and satisfy the stated year-level restriction.
A free activity is not automatically open to every person without limits. This is another example of why a summary must preserve multiple independent conditions rather than keeping only the friendliest-sounding sentence.
17. A required pencil is not a required water bottle
Workshop participants must bring a pencil. The notice describes bringing a water bottle as optional. An accurate practical summary should list these separately.
If the AI announces that all visitors must bring both, it has added a requirement that the source does not contain. The correction is not merely to soften the tone; it is to restore the original policy.
18. A weak one-sentence summary
Consider: “Cedar School is holding a free reading event on 14 November, with activities for pupils.” This is not necessarily false, but it omits the deadline, different entry rules, specific audience, time, venues and materials.
For a parent who only wants to know the event exists, the summary might provide a starting point. For someone deciding whether to register a Primary 6 child, it is not complete enough to guide the next action.
19. A misleading one-sentence summary
Now consider: “Everyone must register by 10 November and bring a water bottle to Room B for the two-hour Reading Fair.” This statement is not merely short. It wrongly applies workshop registration to all visitors, makes an optional item mandatory and confuses the event’s venue.
The distinction between omission and distortion is important. A summary can be insufficient because it leaves out necessary facts, or false because it changes the facts it chooses to include.
20. A concise faithful general-visitor summary
“The fictional Cedar Reading Fair is on Saturday, 14 November 2026, from 10:00 to 12:00 Singapore time in the Cedar School Hall. General entry is free and does not require advance registration. A separate workshop has its own rules.”
This short paragraph preserves the most important general-admission conditions and alerts readers that the workshop should not be treated as having the same entry requirements. It is suitable for a general visitor’s first question.
21. A concise faithful workshop summary
“Story Builders is a free Primary 5–6 workshop on 14 November from 10:30 to 11:15 in Room B. Advance registration is required by 17:00 on 10 November. Capacity is twenty; participants must bring a pencil, while a water bottle is optional. Remaining places are not known.”
This longer summary retains the details a parent would need to evaluate the proposed workshop. It does not pretend to guarantee a place or claim that registration has already succeeded.
22. Summary length depends on the reader
A public poster may need a short description plus a link to full rules. An internal registration checklist must often retain every eligibility condition and deadline. A reading-comprehension answer may need to explain how the two activities differ.
An AI should aim for the shortest response that still preserves the information necessary for the user’s purpose. “Shorter” is not a licence to remove the condition that determines the decision.
23. What information loss actually means
Compression intentionally omits some detail. In data science, lossy compression is not perfectly reversible: the original source cannot necessarily be reconstructed from the compressed representation.
Natural-language summarisation is usually lossy in that broad sense. The design challenge is selecting which information may be omitted without altering the core meaning or misleading a reader who relies on the result.
24. Facts and attribution should travel together
A source may describe an event as scheduled, proposed, cancelled or completed. The summary should retain that status where it matters. A planned event is not proof that it actually took place.
Our Cedar fixture is explicitly fictional. An AI that turns it into a real school event announcement or historical attendance report has crossed beyond the evidence, even if every time and capacity number is copied correctly.
25. Source quotes can be incomplete too
Quoting a short phrase accurately is not enough when its surrounding sentence contains an exception. “Registration required” may be true of the workshop and false of the general fair.
A trustworthy answer cites or preserves the passage’s scope and avoids using a quotation fragment to support a broader claim. Extracting text and understanding what it applies to are separate tasks.
26. A fact checklist improves review
Before approving a summary, list the material facts: event, date, start/end, venue, audience, fee, registration condition, deadline, capacity, required materials and optional items. Compare each summary statement against the appropriate source fact.
This is often more dependable than asking a model whether its own writing “looks complete”. A source-to-summary checklist makes missing constraints visible and allows a reviewer to inspect the transformations.
27. Why a model can preserve numbers and still be wrong
A response may mention 10 November, 14 November, twenty participants and 10:30 without assigning them to the right fields. The digits alone do not establish accuracy.
The semantic roles of the values are essential: registration deadline versus event date, maximum capacity versus remaining vacancies, workshop start versus general admission start. A reliable AI preserves those pairings.
28. Twenty-eight claims for an AI to classify
Use SUPPORTED when a claim follows from the fictional notice, CONTRADICTED when it conflicts with it, and NOT ESTABLISHED when it requires information that was not supplied. The first type needs faithful reading; the second identifies distortion; the third protects against invented certainty.
The exercise is a controlled teaching case, not evidence that any AI product would achieve a particular score on summarisation.
- 01. The fictional fair date is 14 November 2026 — SUPPORTED.
- 02. The general fair runs from 10:00 to 12:00 — SUPPORTED.
- 03. The general venue is Cedar School Hall — SUPPORTED.
- 04. General admission is free — SUPPORTED.
- 05. Every general visitor must register in advance — CONTRADICTED.
- 06. Advance registration is required for the workshop — SUPPORTED.
- 07. The workshop takes place in Room B — SUPPORTED.
- 08. The workshop runs from 10:30 to 11:15 — SUPPORTED.
- 09. The workshop is for Primary 5 and 6 pupils — SUPPORTED.
- 10. The workshop capacity is at most twenty registered participants — SUPPORTED.
- 11. The workshop deadline is 17:00 on 10 November — SUPPORTED.
- 12. Workshop participants must bring a pencil — SUPPORTED.
- 13. A water bottle is mandatory — CONTRADICTED.
- 14. Every general visitor is directed to Room B — CONTRADICTED.
- 15. The workshop is scheduled for two hours — CONTRADICTED.
- 16. The general fair is scheduled for two hours — SUPPORTED.
- 17. Every general visitor must bring a pencil — CONTRADICTED.
- 18. Exactly twenty workshop seats are confirmed available now — NOT ESTABLISHED.
- 19. The event has already taken place and actual attendance was verified — NOT ESTABLISHED.
- 20. The fixture identifies a real Cedar School fair open to the public — CONTRADICTED; it is invented.
- 21. General admission requires no advance registration — SUPPORTED.
- 22. Workshop participation has no fee — SUPPORTED.
- 23. The workshop requires no advance sign-up — CONTRADICTED.
- 24. All twenty workshop places are already filled — NOT ESTABLISHED.
- 25. The workshop ends at 11:15 — SUPPORTED.
- 26. The workshop is open to every pupil below Primary 5 — CONTRADICTED.
- 27. Workshop registration closes at 10:30 on event day — CONTRADICTED.
- 28. A general visitor will definitely be asked to show identification at the entrance — NOT ESTABLISHED.
29. Reconcile the reference labels
Supported are 01–04, 06–12, 16, 21, 22 and 25: fifteen. Contradicted are 05, 13, 14, 15, 17, 20, 23, 26 and 27: nine. Not established are 18, 19, 24 and 28: four. Fifteen plus nine plus four equals twenty-eight.
The distinction among the three categories matters. A false capacity statement is not just an incomplete summary. A claim about how many seats are currently free is unestablished because the notice never supplied live availability.
30. A summary can be wrong by expanding its audience
The instruction “Primary 5 and 6 pupils only” belongs to the workshop. It cannot be used to exclude younger or older visitors from the wider fair under the general admission facts.
An AI should track which people each condition governs. This is especially important when a source contains multiple programmes, products, eligibility pathways or rooms under one broad heading.
31. Negative facts are often important
“No advance registration required for general entry” is a useful fact in this notice. Removing it may force a reader to guess whether registration is needed, even though the source provides a clear answer.
Similarly, the absence of a participation fee and the fact that water bottles are optional can matter. A summary should not routinely drop negative and optional statements merely because they contain few keywords.
32. Preserve time and certainty
The event is announced for a future date within the fictional story. That does not provide a receipt proving it took place, nor the final attendance after the date passes. A planned action and a completed action require different evidence.
A model can say the notice schedules the fair for a particular time. It should not say the organiser successfully ran the event unless an appropriate verified event record exists.
33. Why this matters beyond school notices
Scientific papers contain methods and findings with caveats; contracts contain conditions and exceptions; medicine instructions contain limits and populations; meeting notes distinguish proposals from decisions. Summaries that lose these boundaries can reverse practical meaning.
The same reading discipline applies across domains, although high-stakes decisions may require professional review and the complete authoritative document rather than reliance on a generated short summary.
34. A simple compression quality scorecard
Instead of asking whether the summary includes enough keywords, a reviewer can check separate dimensions: factual support, missing must-have details, preservation of qualifiers, correct attribution and unsupported inferences.
The rubric should be tailored to the task. A general visitor’s summary might omit the workshop capacity but should still avoid claiming that everyone must sign up. A parent planning workshop participation needs the deadline and audience.
35. A classroom exercise
Give pupils the sixteen fictional source facts. Ask them to write one paragraph for a general visitor and one for a parent considering the workshop. Then exchange summaries and underline every required, optional or conditional phrase.
Discuss which omitted details change a reader’s decision and which can reasonably be left out. The goal is not maximal length; it is careful selection of information while preserving meaning.
36. What AI builders should test
Construct multi-part notices with different audiences, separate dates, capacity limits, optional versus mandatory materials, and changing status. Freeze reference answers before asking a summariser to produce short outputs.
Evaluate whether the summary invents a completed action, broadens eligibility or confuses a maximum with remaining availability. Test different output-length constraints, because omissions may increase as the summary becomes shorter.
37. The best final verification
Read the generated summary beside the original notice. For each consequential statement, identify the source fact that supports it. For each mandatory source fact relevant to the user’s purpose, check whether the summary preserves it.
If a detail is unknown, retain that uncertainty. If a fact is ambiguous, do not invent a resolution. A confident, readable summary is useful only when the source-to-output relationship remains traceable.
38. The central lesson
Summarisation compresses words, but should not compress away the conditions that determine meaning. Registration, deadlines, audiences, capacity, venue, optional items and completion status are easy to confuse when several activities share one notice.
A trustworthy AI summariser keeps facts attached to their correct subjects, chooses omissions according to the reader’s purpose and never upgrades a planned or unknown condition into certainty. The shortest reliable answer is the one that still tells the truth.
Frequently asked questions
- Is a short summary always better? — No. It must retain the facts necessary for its intended reader.
- What is information loss? — Detail omitted or changed during a transformation.
- Does preserving all numbers guarantee accuracy? — No. Numbers also need their correct labels and roles.
- Is capacity the same as availability? — No. Maximum permitted places do not prove how many remain.
- Can “optional” become “recommended”? — That may be a separate recommendation, but it should not be presented as the source’s required rule.
- Does an event notice prove the event happened? — No. The notice describes a plan, not a verified occurrence.
- How should I check an AI summary? — Compare its claims and qualifiers against the original source.
