Adding more detail to green marketing claims does not hurt brand appeal.

Positioning & messaging

Reader Note:
The finding is a null: qualified claims did not change brand attitudes compared with broad ones, in either direction. A null with no effect size published and no per-condition sample given cannot rule out a small cost — it shows the study did not detect one. Both claim types did beat an ad carrying no environmental message. The ads were simulated and the outcome was a stated attitude, not a purchase.
Evidence:
Experimental
Vendor interest:
Low
Sample:
Survey of 1,794 consumers in the United States shown simulated advertising across six product and service categories.

Not for

  • Situations far from the one tested, without checking again.
  • The source never says when this data was collected. It could be considerably older than the publication date suggests.
  • The source never says how this number was measured.
  • This was measured in one market. It may not hold where you are.
  • The source says how much it looked at, but not how any of it was chosen.
