Don't be a walkee-talkee" 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
Uses ridicule to shame the target behavior. Portraying the gossiper as an arrogant, mindless radio receiver strips away any sense of self-importance they might get from sharing secrets.
Steal this when
When you need to make an undesirable behavior look foolish and socially unacceptable.
