Sh-h-h. Carnegie - Illinois production soldier sleeping here" poster
The pattern
This still is filed under Us-versus-them positioning.
Define
The buyer is invited into a side. The product is what we use. The named other is what we refuse.
Mechanism
Identity contrast. Choosing the offer is choosing a group. The out-group does as much work as the claim.
Verdict
The category is crowded
Why it works
Uses an innocent child to politely but firmly enforce quiet hours for shift workers in a patriotic context.
Steal this when
You need to ask for a behavioral change in a community and want to soften the demand with an endearing messenger.
