See the Difference

Same writing task. One takes the first draft. One asks for self-critique.

First Draft Only
You: "Write an email declining a meeting invitation politely."

AI writes a reasonable email. It's fine. Generic professional tone, gets the job done, but nothing special.

Acceptable, but could be better.

With Self-Critique
You: "Write an email declining a meeting invitation. Then critique your email for tone, clarity, and warmth. Finally, rewrite it incorporating your critiques."

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.

What to Critique

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.
