The role of predictability in advertising

Doorknob or handle: which would you choose?
Doorknob or handle: which would you choose?

The picture at left shows the inside of the men’s room door in the building where I used to rent a studio, in San Francisco. The knob is the way you get out of the room; the much more prominent grab bar is a useless appendage. During the 18 months I rented this space I used the bathroom certainly 100+ times… and at least 50 of those times I grabbed the bar because my sense memories “knew” that was the right thing to do.

People expect things to work a certain way. And this can have important implications when you’re marketing to them. Ads that play against expectations, especially in web video and TV, can surprise and delight and get through to a dulled viewer. But direct marketing pitches that veer in an unexpected direction—introducing a surprise element in the middle of a sales letter, for example—can turn off a reader and cause them to pitch your message in the recycling bin.

The difference with these scenarios: in the first, the prospect is on the outside, tacitly agreeing to let you try to entice them into your world. In the second, you’ve already created agreement and now you’re violating the contract. That’s why so many paragraphs in classic direct mail letters begin “that’s why”—to let the reader know you’ve established your point and are transitioning to another. And why many direct marketing pitches (including web pages and email, as well as print) will include what my clients at Rodale used to call “head nodders”—statements you know your audience will agree with, used to establish that you are on the same page and your message is reasonable and relevant.

It’s OK to be unpredictable… just as long as you know when to use and not use this strategy. If you’re doing intrusive advertising—which would include most examples of direct marketing—then it’s best to stay within expectations and avoid surprising your prospect except with the wonderful news of your offer and its benefits.
