Keep your eyes open and your mouth shut" poster
The pattern
This still is filed under Negative headline.
Define
The first line is a warning, a refusal, or a negated claim. Something the reader cannot skim as praise.
Mechanism
Pattern interrupt. A negative is harder to slide past than a compliment. The payload must arrive immediately after the stop.
Verdict
The category is full of sunny claims
Why it works
Provides a direct, acceptable alternative script for a high-risk situation. Instead of just saying 'don't talk', it gives the soldier exactly what he should say.
Steal this when
When telling someone not to do something isn't enough, and you need to provide a safer, positive alternative action they can take instead.
