Creative Effectiveness
The repeated finding that the advertisement itself accounts for the largest single share of the sales effect, larger than targeting, reach, or where it ran.

What it does
Reorders where effort goes. If the creative carries the biggest share of the effect, then the hours spent re-cutting an audience segment are being taken from the input that matters most. It is the strongest available argument against treating advertising as a targeting problem with some artwork attached.
When it breaks
The effect itself is well established. Rosengren and colleagues pool studies where judges rate creativity independently, before any outcome is known, so this is no longer a residual left over after the measurable variables are counted. What does not survive is the ranking. The claim that creative outranks reach, targeting and placement comes from one kind of study, a commercial decomposition run by measurement vendors, and the academic work never puts those four in the same model. The size of the effect also moves a great deal depending on which dimension of creativity is measured, in which medium, against which outcome. A Law here would mean a magnitude you can plan against without knowing your category. This is not that yet.
Case
Nielsen's decomposition of advertising's sales contribution across a large set of campaigns placed creative as the largest single driver, ahead of reach, targeting, recency and context. The firm has restated the result across successive analyses.
