To increase sales, first confuse then explain simply

From Science Daily:

The researchers found that by presenting a confusing sales pitch to consumers and then restating the pitch in a more familiar way, they were able to increase sales of a candy bar in a supermarket, increase students' willingness to pay to join a student interest group, and increase students' acceptance of a tuition increase.

Here's what they did, and their hypothesis.

Consumers in the study were confused with an unusual monetary request (e.g., 100 cents for a candy bar, 300 cents to join a student interest group, or 7500 cents for a tuition increase). However, the researchers found that a confusing sales pitch alone -- such as one utilizing technical jargon, confusing terminology, or large and confusing product assortments -- does not lead to greater consumer interest.
Rather, it increases the "need for cognitive closure"; consumers will grasp for easy-to-process or unambiguous information that has direct and obvious implications for judgment and behavior.
Furthermore, the researchers found that this need for cognitive closure will cause particularly susceptible consumers to "freeze" their judgments, that is, hold them with a high degree of confidence and refrain from considering additional evidence that could potentially threaten closure.

I wonder how well this works on teenagers?
