INVESTIGATION 2 OF 6

Find the bridge between evidence and a proposal

Separate a claim, its evidence and its unstated assumption, then qualify the claim when the bridge is weak.

Why learn this? A genuine observation can support a much narrower conclusion than a campaign presents.

Quick recap: A claim is an assertion someone asks you to accept. A warrant is the reasoning connecting evidence to that assertion.

1. Try — read before judging

Original fictional evidence packet. The counts describe inquiries, not unique students, attendance or willingness to use the room.

CLAIM: Eastbank should open the study room every evening.
EVIDENCE: The desk recorded 36 inquiries after 6 p.m. across three Tuesdays.
ASSUMPTION A: Each inquiry came from a different student.
ASSUMPTION B: Tuesday inquiries represent demand on every evening.
ASSUMPTION C: Students who ask would attend if the room opened.
LIMIT: No attendance, other-day or cost-comparison data were collected.

3. Experiment — test your reading

In the claim field, write a recommendation whose scope matches the evidence. In the reason field, state the evidence and the warrant separately.
Use the objection field to identify the strongest untested assumption; do not merely say the sample is small.
Write a reply that changes the recommendation or proposes a bounded test. Explain what result would make you withdraw the proposal.

Follow each connection. A reason supports a claim only if you explain how the evidence makes it plausible.

4. Understand — connect choice and effect

Evidence does not carry its own conclusion

The addition is straightforward: 12 + 15 + 9 = 36 inquiries. The difficult move comes next. Calling these “36 students” assumes each inquiry came from a different person. Calling them evidence for daily opening assumes Tuesday patterns extend to other days. Neither assumption follows from addition.

A warrant supplies the bridge between an observation and a claim. Sometimes it is well supported: a staffing requirement must be met before a staffed room operates. Sometimes it needs investigation: people who ask about a room will use it when it opens. Write the bridge as a separate sentence so another reader can challenge it.

Three useful questions are: What exactly was counted? Under what conditions? What conclusion does that permit? Here the unit is inquiries, the conditions are three Tuesday evenings, and the conclusion concerns a reason to investigate possible demand. Even a complete count of those inquiries would not answer questions about other days or budget priorities.

Qualification is more than sprinkling “perhaps” into an overclaim. Change the claim’s scope: from permanent daily opening to a bounded Tuesday investigation. Then name an outcome that would change your recommendation. If no result could change it, the proposed test is serving as decoration.

Finally, separate empirical and value questions. Attendance records can help estimate use. They cannot by themselves decide how much access for a small underserved group should matter compared with total attendance. State that priority openly rather than hiding it inside a numerical conclusion.

Warrant: The stated or implied reasoning that connects evidence to a claim.
Qualification: A limit on a claim’s strength, scope or conditions.

Worked example — a possible revision, not the only answer

Before

Thirty-six students need the room every night, so it must open daily.

After

Thirty-six inquiries across three Tuesdays justify investigating Tuesday demand, but may include repeat visitors. A Tuesday pilot with attendance records would test whether inquiries translate into use before expansion.

The revised argument distinguishes inquiries from people and demand from actual use. A proposed test is not evidence that its predicted result will occur.

5. Apply — make something and try a new case

Your main artifact

Label claim, evidence and warrant in a paragraph, then add one meaningful qualification.

Keep your artifact in the working draft above. Suggested lengths help you plan; they do not measure quality.

Unfamiliar passage

A café receives 18 comments praising its outdoor tables during one sunny weekend. Its owner concludes that indoor seating is unnecessary.
