Many advertisements use fallacies to boost their effectiveness and impact on readers and the audience.

Shills are used to assure a customer that the product is worth buying, since another customer has given feedback that he approves of it. For example, a tuition advertisement by BrainFit Studio states that a customer is satisfied with its services, and its effects include reducing the time to learn a subject from three days to two hours. The statement is written by a parent to satisfy other parents who want to send their children for the course. However, the “customer” may be a false customer, who has been paid to pose for the advertisement. Alternatively, the statement may be conjured up by the advertiser.

Testimonials are used to convince potential buyers by making fallacious appeals to authorities. Authorities can include celebrities who endorse the product, or scientific authority. For example, an advertisement by BEST selling laptops claim that a notebook or a tablet uses less than half the amount of electricity used by a desktop computer. This will lead potential buyers to believe that their product is more efficient that a computer, and thus buy it. However, the statement may not be scientifically accurate. Still, customers may accept it without any suspicions and buy the product.

However, not all advertisements use fallacies. They may use other forms of psychological mechanisms. Telemarketers contact customers to demonstrate a product’s effectiveness, hence persuading a customer to buy the product. However, the customer is able to judge for himself the effectiveness of a product and is not misled in any way.

Hence, to a larger extent, advertisements use fallacies to advertise products. However, not all advertisements mislead customers to sell their products. In such cases, customers can judge for themselves the effectiveness of the product, making a well-informed decision.
