Final answer:
The advertising technique that fits this description is called weasel words. Weasel words use positive language without making any specific guarantees or claims.
Step-by-step explanation:
The advertising technique that involves the use of positive words without actually making any guarantee is known as weasel words. Weasel words are used to create a positive image or impression without making any specific claims or guarantees. They give the impression of a claim being made, but in reality, they are vague and don't make any concrete promises.
For example, a company might use phrases like 'helps to reduce the appearance of wrinkles' or 'can contribute to weight loss', without making any direct promises. These weasel words make the product or service sound desirable, without actually committing to any specific results or benefits.
Endorsements involve the support or approval of a well-known person, while testimonials are personal accounts or experiences shared by satisfied customers. Facts and figures are statistical data and information that support a claim. Weasel words, on the other hand, are more subtle and use positive language without making any concrete guarantees.
