See the Difference
Same writing task. One takes the first draft. One asks for self-critique.
AI writes a reasonable email. It's fine. Generic professional tone, gets the job done, but nothing special.
Acceptable, but could be better.
Draft: [Initial email]
Critique: "The opening feels abrupt. The reason given is vague. It lacks a concrete alternative..."
Revised: [Warmer, clearer, more helpful email]
Self-identified problems. Actively improved.
Why This Works
AI doesn't automatically give you its best work on the first try. When you ask it to critique its own output, it notices things it missed — awkward phrasing, unclear structure, wrong tone. The revision addresses those specific issues.
This works because style and tone are subjective. AI can judge whether something sounds too formal, too wordy, or too cold — there's no "correct answer" to verify, just appropriateness to evaluate. That's something AI can do on its own.
How to Prompt It
- All-in-one: "Write [X]. Critique it for [aspects]. Rewrite incorporating your critiques."
- Two-step: First get the draft, then ask: "Critique this for tone and clarity, then revise it."
- Specific criteria: "Critique for: (1) professional warmth, (2) clarity of the main point, (3) appropriate length"
- Multiple rounds: After the revision, ask: "Critique and revise once more" (2-3 rounds is usually optimal)
What to Critique
- Tone: Too formal? Too casual? Warm enough? Confident without arrogance?
- Clarity: Is the main point obvious? Any confusing sentences?
- Structure: Does it flow logically? Is the most important thing first?
- Length: Too verbose? Missing important details?
- Audience fit: Right for the reader? Appropriate complexity?
Where This Doesn't Work
Self-critique works for style and quality — not for correctness. Research shows AI cannot reliably detect its own errors in math, logic, or facts. If you ask AI to "check your reasoning" on a math problem, it often makes things worse. For tasks with objectively right or wrong answers, use external verification instead (calculators, code execution, fact-checking). This technique is for polish, not proof.
The Technique
Ask AI to write, then critique, then revise. Be specific about what to critique — tone, clarity, structure. Two or three rounds usually gets you there. Works for writing; skip it for math and reasoning.
When to Use This
- • Professional emails where tone matters
- • Content that needs to be clear and engaging
- • Any writing where you want more than a first draft
- • Refining explanations for a specific audience
- • When the first output is close but not quite right
When to Skip This
- • Math problems — AI can't verify its own calculations
- • Logical reasoning — self-correction often makes it worse
- • Factual claims — AI can't fact-check itself
- • Code correctness — use actual execution to test
- • Quick tasks where the first draft is good enough
