Final answer:
Persuasion is primarily used for promotion when the product benefits from analytical differentiation, such as in the sale of a highly technical item to an audience that values data and facts. The central route to persuasion involves logical arguments based on product qualities, while the peripheral route utilizes positive associations like celebrity endorsements.
Step-by-step explanation:
Persuasion becomes the primary promotion goal when a product can benefit from being distinguished by its features and quality, as during a situation where there are monopolistic competition and the audience is analytical and willing to engage with this detailed information. An example of this would be in the case of selling a highly technical product like computers to small business owners, who are likely to be influenced by the computer's quality and its processing speed and memory capacity. This approach uses the central route to persuasion, which is logic-driven and relies on data and facts to make a convincing argument. The central route can lead to a more durable impact on the consumer's attitude towards the product.
Conversely, the peripheral route to persuasion, which relies on positive associations and less information processing, such as celebrity endorsements or positive emotions, may not create as lasting of an attitude or behavior change. This method is often used when the audience is less analytical or interested in processing detailed product information and can be more successful in industries like clothing or with products appearing in product placements on shows like American Idol.
