Show notes

Ethan Decker applies brand science to questions marketers face every day: which ideas hold across contexts, which depend on the situation and which have no evidence behind them.

The discussion covers the banana curve of light and heavy buyers, brand repertoires, the mental shortcuts people use when choosing, and salience at the buying moment.

Half the ideas we have about advertising are wrong. Trouble is, we don't know which half.

— Ethan Decker

The Playbook

The core principles from this conversation.

  1. 1 Laws do not change. Levers sometimes work. Hogwash never does.
  2. 2 Design for light buyers: they are most of your volume
  3. 3 Stop retesting what is already established. Test what is genuinely unknown.
  4. 4 Salience at buying moment beats awareness in the abstract
