The 4-Question
Pressure Test

Claude can be wrong and sound completely sure, which is the annoying part. These are the 4 prompts I paste in after every important answer. Each one catches a different kind of error. Run all four and very little slips through.

When To Use It

Run it when being wrong is expensive. Think of a decision you can’t easily undo, something you’re sending to your boss or a client, or anything legal, medical, financial or hiring-related. Skip it for brainstorming or anything where a mistake just means a redo.

How To Run It

After Claude’s first answer, paste the prompts one at a time, in order, in the same chat. Each one builds on what the last one surfaced. Keep web search on so Prompt 4 can point you to real sources. By the end you either trust the answer for good reasons or have a short list of what to check.

Prompt 1: The Confidence Check

Catches overconfidence. Claude sounds sure by default. This makes it rate its own answer, tag each claim high, medium or low, and say what would raise the score. Treat the score as a signal, not proof. A drop in confidence tells you where to dig.

Prompt 1: Confidence Check
On a scale of 1-10, how confident are you in the answer you just gave me? Be honest. Calibration matters more than sounding sure. Specifically tell me: 1. THE SCORE A single number, 1-10. 2. WHY THAT SCORE AND NOT HIGHER What’s making you less than fully sure? (Thin training data, ambiguous question, fast-moving field, conflicting sources, my missing context, etc.) 3. WHY THAT SCORE AND NOT LOWER What’s genuinely solid in your answer? Where are you on firm ground? 4. WHICH PARTS ARE WHICH Walk through your answer and tag each major claim: - HIGH CONFIDENCE: I’d defend this - MEDIUM CONFIDENCE: directionally right, details may be off - LOW CONFIDENCE: educated guess, verify before acting 5. WHAT WOULD PUSH THE SCORE UP The 2-3 specific things you’d need to know or check to move from a 6 to a 9. (More context from me? A specific source? A different framing of the question?) RULE: Don't just lower the score to look humble. If a claim depends on facts that change fast (prices, laws, product features, anything after your training data), say so and mark it LOW until it's checked.
Prompt 2: The Failure Mode Hunt

Catches hidden assumptions. The first answer assumes a normal version of your situation. This one makes Claude list what it assumed, find the edge cases where its answer breaks and argue the opposite side.

Prompt 2: Failure Mode Hunt
Where could the answer you just gave me fall apart? What’s the version of this answer that would be wrong, and for whom? Specifically: 1. THE TOP 3 WAYS THIS COULD BE WRONG The most plausible scenarios where your answer doesn’t hold. Rank them by likelihood. For each, tell me what would have to be true for the failure to happen. 2. THE ASSUMPTIONS YOU MADE List every assumption baked into your first answer. Things you assumed about my situation, my context, my industry, my level of expertise, my goals. Flag the ones I haven’t confirmed. 3. THE EDGE CASES YOU SKIPPED The unusual-but-real situations where your answer breaks. Be specific. Not “in some cases this might not apply,” but “if you’re in [X situation], the answer flips because [Y].” 4. THE STEELMAN OPPOSITE Argue the opposite of what you said. Make the strongest possible case for the OTHER answer. What would the smart person who disagrees with you say? 5. THE TELL What signal in MY situation would tell me your answer doesn’t apply? What should I look for in my own context to know I’m the exception?
Prompt 3: The Expert Review

Catches beginner mistakes. The first answer is usually the smart-generalist version. This puts Claude in the shoes of someone with 20 years in the field and has it rewrite the answer the way they would, plus the one question that expert would ask you first.

Prompt 3: Expert Review
Now take the perspective of a top expert in this field, someone who’s been doing this for 20+ years and has the scars to prove it. Critique your previous answer like they would. Specifically: 1. NAME THE EXPERT First, define who this expert IS. (Not a real person, a role: “a senior IP attorney with 20 years in tech transactions,” “a CFO who’s taken 3 companies through Series B,” “a family medicine doctor with a focus on autoimmune.”) Be specific about their lens. 2. WHAT YOU GOT RIGHT What in your first answer would the expert nod at? Don’t pad. Only the genuinely solid parts. 3. WHAT YOU OVERSIMPLIFIED What did you flatten that this expert would say has more nuance? Where would they push back on a generalization? 4. WHAT AN AMATEUR GETS WRONG HERE THAT THE EXPERT NEVER WOULD The 1-3 mistakes a smart-but-non-expert (which your first answer often is) typically makes in this domain, and which of them showed up in your answer. 5. THE EXPERT’S REWRITE Rewrite your original answer the way the expert would deliver it. Same goal, different depth. Use the actual frameworks, vocabulary, and judgment calls a real expert would. 6. THE EXPERT’S FOLLOW-UP QUESTION The single question this expert would ask me before fully committing to an answer. (This is usually the most useful sentence of the whole pressure test.)
Prompt 4: The Verification Path

Catches blind trust. This one makes Claude tell you exactly what to check, where and how long it takes, including when to stop and call a real lawyer, doctor or accountant. Click every link it gives you. If a source doesn’t open or doesn’t say what Claude claimed, that’s your answer.

Prompt 4: Verification Path
How would I verify your answer on my own? Tell me exactly what to check, where to check it, and how long it’ll take. Specifically: 1. THE 3-5 SPECIFIC THINGS TO CHECK Not generic “do research.” The actual sources, calculators, documents, or people. For each item: - WHAT to verify (the specific claim from your answer) - WHERE to verify it (the actual source: government site, specific tool, named expert, calculator URL, person to call) - WHY this is the highest-signal verification (vs. easier-but-weaker checks) 2. THE 30-MINUTE VERIFICATION PLAN If I have 30 minutes, the exact sequence: do A first, then B, then C. Use web search to find the real sources and give me working links. Never make up a URL; if you can't find one, name the source and tell me what to search for. 3. THE 5-MINUTE GUT-CHECK VERSION If I’m time-strapped: the single fastest check that’d catch the most likely error. The 80/20 of verification. 4. THE ONE MOST IMPORTANT THING If I only verify ONE thing from your answer before acting, what is it? The single highest-stakes claim: the one where being wrong matters most. 5. WHEN TO BRING IN A HUMAN The threshold at which I should stop trusting AI verification and bring in a real expert (lawyer, doctor, CPA, engineer, etc.). What signal would tell me “this is past the AI’s pay grade”? 6. WHAT WOULD CHANGE YOUR ANSWER If I come back and tell you what I found in verification, what specific finding that would make you revise your original answer materially? Tell me so I know what to bring back to you.
Why The Order Matters

01

The confidence check shows you where to push

You learn which parts of the answer are shaky and which are firm.

02

The failure hunt finds the cracks

Now Claude hunts problems in exactly the shaky areas. The assumption list usually surfaces the real issue.

03

The expert review goes deeper

With the weak spots already in the chat, the expert rewrite is far sharper than if you asked for it cold.

04

The verification path closes the loop

Claude already knows where it’s unsure, so its list of what to check is specific.

Only Have Time For One?

Run Prompt 3, The Expert Review. It catches the most on its own. The full stack is what gets you from "Claude told me X" to "I checked X, and here’s why it holds up."
