Imagine a pleasant, smiling person someone comes up to you and says "Excuse me, would you be willing to sign this petition in favor of cleaner water in our state?" Most people (whether they know much about the issue or even care much about the state of water, are likely to agree to this request. Now imagine you get a call the next day thanking you for signing the petition and asking whether you will donate to the cause of cleaner water in the state. Would you contribute? Plenty of research on this "foot in the door" technique has shown that people who signed the petition are much more likely to contribute than those who didn't. The interesting part is that research has also shown that the people who sign the petition actually come to believe in the cause more than people who didn't sign the petition. So, such commitments can not only affect your future behavior, but also form attitudes about things where you earlier had no firm beliefs. One of the factors that make commitments more effective at changing future behavior is making the commitment "active" ( written or verbal instead of just mental).
That was all just background for the main point of this post. I recently saw a flyer in the mail for
Gerber Life Insurance (or something like that) that had this dramatic headline "Isn't your child's future worth $1 a day?" and then proceeded to explain how for this small daily cost, your child could be insured in case something should happen to you. Just looking at this ad raised a simple question in my mind. Would it make any difference to the effectiveness of the campaign if the headline instead had read "Is your child's future worth $1 a day?" While the difference in the two headlines is trivial in semantic terms, I think the cognitive process of these two questions are different. The former is almost framed as a rhetorical question while the latter almost demands that the reader make an answer. My guess is that the latter would make for a more active commitment than the former and thus may be more effective. A third version could include two check boxes below the question with YES and NO as the two options. This again seems to enhance the need for the reader to respond and thereby make a more active commitment.Why should you care? I have no idea. I think this would make for an interesting experiment and thought I would document this idea here for possible future use. Wouldn't it be interesting if changing TWO LETTERS in an ad could have a measurable impact on the effectiveness of the ad? This is the kind of stuff that fascinates me. Now you know.
