When media create pictures in the head, they act as agents of consonance.

By repeating and aligning images across outlets they build a shared, agreed picture of the world in people's minds.

This convergence of media portrayals fosters agreement rather than clash in public perception.

Corporate agenda-setters names who chooses topics, which is a different idea from producing mental pictures.

Political representatives stand for constituents in governance, not for the media's image-making role.

Tools of dissonance would sow conflict and disagreement, the opposite of the shared harmony consonance describes.
