Stress-Test Your Argument With a Sceptic
You get a ranked list of the weakest points in your argument, each paired with the best opposing view and a practical fix. It works because the AI is given a specific adversarial role and told to be fair, so it critiques instead of agreeing with you.
The prompt
Act as a sharp but fair-minded sceptical reader who has no stake in my success and wants the truth.
Task: Challenge the argument below so I can strengthen it before I publish it to {target_audience}.
Argument:
{my_argument}
Steps:
1. Restate my main claim in one sentence so I know you understood it.
2. Find the three most serious weaknesses, such as gaps in evidence, hidden assumptions or ignored counterpoints. Rank them from most to least damaging.
3. For each weakness, explain why a reasonable person might disagree with me, using the strongest version of their view.
4. Suggest one concrete change to my wording or evidence that would answer each weakness.
5. Do not flatter me or invent facts. If something is a matter of opinion, say so.
Output: A one-sentence restatement, then three numbered sections headed "Weakness", "Why someone would disagree" and "How to fix it". Keep each section to two or three sentences. Finish with one line stating which fix to make first.
Change the parts in curly braces. Use it on a near-final draft, such as a blog post, pitch or proposal, before anyone else reads it.

Act as a sharp but fair-minded sceptical reader who has no stake in my success and wants the truth. Task: Challenge the argument below so I can strengthen it before I publish it to small business owners who read our monthly newsletter and are wary of new software. Argument: Every small business should move its bookkeeping to cloud accounting software this year. Spreadsheets cause errors and waste hours each month. Cloud tools update automatically and let your accountant see the figures in real time. Businesses that stay on spreadsheets will fall behind competitors who make faster decisions. Steps: 1. Restate my main claim in one sentence so I know you understood it. 2. Find the three most serious weaknesses, such as gaps in evidence, hidden assumptions or ignored counterpoints. Rank them from most to least damaging. 3. For each weakness, explain why a reasonable person might disagree with me, using the strongest version of their view. 4.
