The Use of Ads
Advertising may legally contain opinions and exaggerations which are misleading. There "legal lies" are called puffs because they puff up a product's qualities and make it seem better than it really is. Learn how to spot advertising puff.
Advertising is controlled by law. The Federal Trade Commission (FTC) regulates the content of advertisements—what the manufacturer can and can not say about its product. You as a Consumer can protect yourself from misleading ads by learning how to recognize them.
Misleading advertising often presents the seller's opinion as if it were fact. "Zeno's Cola is the finest soft drink. Acme Cars give you the most comfortable ride in town." When you see advertisements like this, ask yourself "Who says so?" This is the type of advertising puff that reflects an opinion. The words "finest" and "most" show that a judgement is being made—a personal opinion, not a statement of fact. Of course the Zeno Company thinks their cola is the finest. They want you to think so too, so you'll buy it.
Some advertising puffs try to connect an unrelated quality to a product. For example, beauty and popularity are often linked with perfume, cars, mouthwash, or toothpaste. This kind of advertising is called "image making". Will you really meet nicer people if you drive a Panther automobile? Will people think you're sexier if you brush your teeth with Sparkle toothpaste? Of course not. When you see these advertisements, remember that very few products will automatically make you a better or happier person. Some advertising puffs describe the product accurately but are still misleading. For instance, a leading hamburger is described as a quarter of a pound. This statement is true: the hamburger does weigh a quarter of a pound—before cooking. Since it's purchased after being cooked, this claim may be classified as puff.
Check the frozen food aisle in your supermarket. A frozen pie is labeled as a "nine-inch pie." This statement is true if you measure the pie from the outside of the rim on one side to the other side. The actual body of the pie is only 7.5 inches. If you buy a standard nine-inch pie plate for making your own pres, you'll see that the nine inch measurement is for the inside of the pie.
You should always question the claims made by any advertisement. Ask yourself: will the product really do all of these things? Is it truly the best?
Decide which of the following advertisements reflects/reflect only the seller's opinion?
A.Acme Cars give you the most comfortable ride in town.
B.Use Sparkle Toothpaste to whiten your teeth.
C.White Cat, washes whiter.
D.All of the above.
