Contrastive Example Calibration: Show It What You Want AND What You Don't — One Negative Example Beats Three Positive Ones

Demonstrate both the 'desired output' and the 'output that shouldn't appear' at the same time, so the AI calibrates between the two poles; for tasks about tone and precision, a single negative example often outperforms three positive ones.

01PROMPT
Task: {{task}}

GOOD example (match this tone and depth):
{{good}}

BAD example (avoid this, it is too {{badtrait}}):
{{bad}}

Now produce the output for: {{input}}. Calibrate against both anchors.

Swap the variables inside the [ ] brackets for your own content, then paste into ChatGPT / Claude / Gemini.

02CONTEXT / Why it works

Can't get the AI to nail the tone you want? Beyond positive examples, give it one 'not like this' counter-example too — it will calibrate between the two poles, and that's usually more accurate than giving it only good examples.
