16 C.F.R. § 255.2 Consumer endorsements.
Title 16 - Commercial Practices
(a) An advertisement employing an endorsement reflecting the experience of an individual or a group of consumers on a central or key attribute of the product or service will be interpreted as representing that the endorser's experience is representative of what consumers will generally achieve with the advertised product in actual, albeit variable, conditions of use. Therefore, unless the advertiser possesses and relies upon adequate substantiation for this representation, the advertisement should either clearly and conspicuously disclose what the generally expected performance would be in the depicted circumstances or clearly and conspicuously disclose the limited applicability of the endorser's experience to what consumers may generally expect to achieve. The Commission's position regarding the acceptance of disclaimers or disclosures is described in the preamble to these Guides published in the (b) Advertisements presenting endorsements by what are represented, directly or by implication, to be “actual consumers” should utilize actual consumers, in both the audio and video or clearly and conspicuously disclose that the persons in such advertisements are not actual consumers of the advertised product. (c) Claims concerning the efficacy of any drug or device as defined in the Federal Trade Commission Act, 15 U.S.C. 55, shall not be made in lay endorsements unless (1) the advertiser has adequate scientific substantiation for such claims and (2) the claims are not inconsistent with any determination that has been made by the Food and Drug Administration with respect to the drug or device that is the subject of the claim. Guide 2, Example 1: An advertisement presents the endorsement of an owner of one of the advertiser's television sets. The consumer states that she has needed to take the set to the shop for repairs only one time during her 2-year period of ownership and the costs of servicing the set to date have been under $10.00. Unless the advertiser possesses and relied upon adequate substantiation for the implied claim that such performance reflects that which a significant proportion of consumers would be likely to experience, the advertiser should include a disclosure that either states clearly and conspicuously what the generally expectable performance would be or clearly and conspicuously informs consumers that the performance experienced by the endorser is not what they should expect to experience. The mere disclosure that “not all consumers will get this result” is insufficient because it can imply that while all consumers cannot expect the advertised results, a substantial number can expect them. [See the cross reference in Guide 2(a) regarding the acceptability of disclaimers or disclosures.] Example 2: An advertiser presents the results of a poll of consumers who have used the advertiser's cake mixes as well as their own recipes. The results purport to show that the majority believed that their families could not tell the difference between the advertised mix and their own cakes baked from scratch. Many of the consumers are actually pictured in the advertisement along with relevant, quoted portions of their statements endorsing the product. This use of the results of a poll or survey of consumers probably represents a promise to consumers that this is the typical result that ordinary consumers can expect from the advertiser's cake mix. Example 3: An advertisement purports to portray a “hidden camera” situation in a crowded cafeteria at breakfast time. A spokesperson for the advertiser asks a series of actual patrons of the cafeteria for their spontaneous, honest opinions of the advertiser's recently introduced breakfast cereal. Even though the words “hidden camera” are not displayed on the screen, and even though none of the actual patrons is specifically identified during the advertisement, the net impression conveyed to consumers may well be that these are actual customers, and not actors. If actors have been employed, this fact should be disclosed. [Guide 2] [45 FR 3872, Jan. 18, 1980]
