Most campaign briefs only show the upside. The big idea, the hook, the reasons it'll land.
That one-sided view is exactly why campaigns miss. You never stress-tested the parts that could go wrong.
An anti-brief flips the script. It's a version of your campaign written from the audience's point of view, built to expose confusion, boredom, or resistance before you spend a dollar on it.
Try this prompt:
You are a skeptical member of my target audience. Read the campaign brief below and tell me honestly how it could fail with someone like you.
Cover these three angles:
1. CONFUSION: What parts of the message are unclear, contradictory, or require too much effort to understand?
2. BOREDOM: What feels generic, expected, or easy to scroll past?
3. RESISTANCE: What might make someone like me distrust, ignore, or actively dislike this?
For each issue, explain what's causing it and suggest one specific fix.
Campaign brief:
[PASTE YOUR BRIEF]
Target audience:
[DESCRIBE WHO THIS IS FOR]
Run this before every brief goes to production. It's a lot cheaper than finding out after launch.
Happy prompting!
