The role of a hero message versus supporting messages
Launch library · evergreen read

A hero message is the single sentence an audience should still remember after everything else about a campaign has faded from memory, which means it must survive being repeated by someone who only half remembers the surrounding details a week later, long after the original decision has quietly been forgotten.
Supporting messages exist to serve that central idea, not to compete with it for attention or airtime. Each one answers a different question a sceptical audience might reasonably ask, whether about cost, credibility, timing or relevance, while always pointing quietly back to the same core claim underneath everything.
Confusion tends to arise when supporting messages are given roughly equal weight to the hero message itself, because an audience presented with five equally loud points usually retains almost none of them with any real clarity once the moment has passed, particularly when several people share responsibility for the outcome.
Discipline here is mostly an act of subtraction rather than addition, however unnatural that feels to a team full of good ideas. The hardest part of message architecture is deciding what a spokesperson is simply not allowed to lead with, even when it happens to be true.
