Map explicit premises, an unstated assumption and a counterexample without evaluating people. The worked result is a written example for practice; the AI steps have not been tested.

Make a start
One step at a time.
3 steps
Start with the synthetic worked example or other non-sensitive inputs. Run one prompt at a time in your chosen AI tool. Replace any bracketed placeholders with the requested material, check each reply, and supply the source or earlier outputs that step needs. Paste them again if the tool lacks that context.
Start with the synthetic example, then adapt each prompt to your task.
01
Open a chat and paste the example
Open https://chatgpt.com and choose New chat. Copy every line under Input in this guide into the message box. Then add the prompt below (the instructions telling the assistant what to do) and send both together. Expect a written response shaped like the example under Output. The wording may differ. If the assistant asks for information already in the input, point to that line; if a necessary fact is missing, keep it unknown rather than guessing. The Input explains premise, conclusion and assumption before you use them.
Your starting prompt
Map the short argument using the supplied definitions. Give the conclusion, two stated factual premises, one clearly labelled unstated assumption and one hypothetical case that would weaken the recommendation. Do not convert the assumption into a fact or invent group availability.
02
Check the specific result
Check that the afternoon recommendation is the conclusion, while venue and lighting facts are reasons. The group’s availability must be an unknown assumption, not a claimed fact. Compare it with the Input yourself. If the response fails a check, paste the correction prompt below into the same chat. Recheck the corrected version before saving it.
Your starting prompt
Recheck which statements are actually present in the original argument. Move any invented availability claim out of the premises and label it as an assumption or hypothetical case. Keep the conclusion separate from the reasons.
03
Try it with your own example
Open a new chat. Copy the prompt below, then replace [PASTE YOUR INPUT HERE] with your own non-sensitive facts and rules. Include the kinds of details listed under Requirements. Send the whole message. Expect the same kind of result as this guide, using your values. Compare every name, number and rule with your input. If something differs, point to the exact mismatch and ask for a corrected complete answer. Save only a version you have checked.
Your starting prompt
Map my argument using the definitions below. Separate its conclusion, stated factual premises and any unstated assumption. Label the assumption as an inference, not a source fact. Give one clearly hypothetical case that would weaken the recommendation. Do not invent evidence or people’s availability.
Use only the new input below. If a fact needed to finish is missing, ask me for it before choosing an answer.

Optional: improve the result
Strengthen the argument with one extra fact
Add a declared fact and see precisely which uncertainty it resolves. This extension uses the worked example. Return to that example chat, or paste its input and your checked example answer into a new chat first. Do not apply its sample values unchanged to your own input.
Advanced prompt
New made-up fact: all group members confirmed they can attend next Saturday from 14:00 to 16:00. Show how this affects the availability assumption. State any remaining limits without inventing another venue, lighting system or schedule.

01 / The starting point
Synthetic input
Made-up example for practice. Argument: “Our sketch group uses the conservatory. The conservatory has good daylight in the afternoon and no lighting available after dark. Therefore, we should hold the next sketch session in the afternoon.” A premise is a stated reason; a conclusion is the claim those reasons support; an assumption is an unstated link the reasoning depends on. Task: identify the conclusion, the two stated factual premises and one important unstated assumption. Do not invent the group’s availability or decide that the conclusion must be correct.
Copies text only. For image or file tasks, use the source files named in the steps too.
Written example for practice; not a recorded AI response.
Conclusion: hold the next sketch session in the afternoon.
Stated factual premises
1. The group uses the conservatory.
2. The conservatory has good afternoon daylight and no lighting available after dark.
One important unstated assumption: an afternoon session is workable for the group, including attendance. The argument does not establish availability.
How the reasons support the conclusion: afternoon daylight addresses the stated lighting limitation in the chosen space.
What could weaken the recommendation: if no group members were available in the afternoon, the suggested time might not work. That is a hypothetical counterexample, not a known fact.
The argument offers a reason to prefer afternoon; it does not prove that afternoon is the only possible choice.
These checks use the worked example and its particular facts. With your own material, check your actual names, numbers, sources and rules; do not reuse the sample’s values as the answer.

A few things to watch for.
Finding an unstated assumption does not automatically make an argument useless; it shows what still needs checking.
Do not treat a counterexample you invent for learning as something that really happened.
