Definition
"Anecdotal evidence" is used in more than one setting, and its meaning depends on the context. In consumer protection, it means reports of results from individual consumers or patients, or from a small group of them, offered to show what a product does. Source: FTC v. QT, Inc., Memorandum Opinion and Order
Experts in FTC matters treat it as a starting point for testing rather than as proof: it can be hypothesis generating, but hypotheses must be carefully tested because many do not prove to be accurate. Source: Report of Omer Kucuk, M.D., ¶ 45
Key legal rules
A claim that rests on customer anecdotes is still a claim, so it has to be truthful and substantiated. Three rules put that to work:
- Claims about a product’s attributes, performance, or efficacy carry an express or implied representation that the advertiser had a reasonable basis when the claims were made; without that basis, the representations are deceptive or misleading. Source: Initial Decision Filed by Chief Administrative Law Judge, D. Michael Chappell [Public Record Version], n.5
- Health, safety, and efficacy claims, including for dietary supplements, must be substantiated with competent and reliable scientific evidence; anecdotal evidence and consumer testimonials are not that evidence, honest endorser opinion is not enough without scientific support for the underlying claim, and testimonials do not adequately substantiate health-related efficacy claims. Source: Modified Stipulated Final Judgment and Order for Permanent Injunction and Monetary Relief, Attachment A (Notice to Distributors)
- The existence of some satisfied consumers is not a defense to false and misleading advertising, as FTC complaint counsel argued in the Daniel Chapter One matter, citing FTC v. Amy Travel Services, Inc. Source: Complaint Counsel's Motion in Limine, FTC Docket No. 9329

A testimonial reports what happened to one person after using a product, and that sequence alone cannot show that the product caused the result. As the Seventh Circuit put it in FTC v. QT, Inc., 512 F.3d 858, 862 (7th Cir. 2008), testimonials are not a form of proof because most represent the post hoc ergo propter hoc fallacy, since a person who feels less pain after putting on a bracelet may have enjoyed the same reduction without it. Source: Initial Decision Filed by Chief Administrative Law Judge, D. Michael Chappell [Public Record Version], n.5 The FTC's Dietary Supplements: An Advertising Guide for Industry makes the same point about placebo effects, saying that even genuine experiences may be attributable to a placebo effect or other factors unrelated to the supplement. Source: Memorandum in Support of Plaintiff's Application for an Order to Show Cause Why Defendants Enforma Natural Products, Inc. and Andrew Grey and Nonparty Michael Ehrman Should Not Be Held in Civil Contempt (quoting FTC, Dietary Supplements: An Advertising Guide for Industry) A witness in an FTC administrative hearing added a second reason: an anecdote is typically an observation in one or a few patients that may have been seen by chance, and with so few patients it may not be generalizable to the population. Source: Testimony of James A. Eastham, M.D., FTC Docket No. 9344
The substantiation duty exists because buyers usually cannot sort out coincidence from effect on their own. An FTC administrative law judge reasoned that the placebo effect of consumer expectations when taking a purported remedy makes it difficult for consumers to verify product effectiveness for themselves. Source: Initial Decision Filed by Chief Administrative Law Judge, D. Michael Chappell [Public Record Version], n.5 Requiring controlled evidence before a health claim is made keeps a seller from collecting money on the strength of results the buyer has no means to check, and treating anecdotes as a reason to run a study, not as the study, preserves their legitimate role in generating hypotheses.
Enforcement examples
FTC v. Sagee U.S.A. Group, Inc. (brain-health dietary supplement)
Stipulated Final Judgment and Order for Permanent Injunction and Monetary Relief (with Modified judgment Attachment A) (settlement dated July 2, 2006)
Sagee U.S.A. Group, Inc. and its chief executive officer settled with the FTC over advertising claims for covered products, which include dietary supplements such as Sagee and Dia-Cope. Source: Modified Stipulated Final Judgment and Order for Permanent Injunction and Monetary Relief, Attachment A (Notice to Distributors) Among the representations the judgment restrains is that the Sagee supplement repairs damaged brain cells. Source: Stipulated Final Judgment and Order for Permanent Injunction and Monetary Relief (Sagee) The settlement was not an admission, because the agreement does not constitute an admission that Sagee USA or its chief executive has violated any law. Source: Modified Stipulated Final Judgment and Order for Permanent Injunction and Monetary Relief, Attachment A (Notice to Distributors)
Outcome. The defendants are permanently restrained and enjoined from making health, performance, or efficacy representations about the product, including through endorsements. Source: Stipulated Final Judgment and Order for Permanent Injunction and Monetary Relief (Sagee) They may make such a representation only if, at the time, they possess and rely upon competent and reliable scientific evidence that substantiates it. Source: Stipulated Final Judgment and Order for Permanent Injunction and Monetary Relief (Sagee) The notice Sagee USA had to send distributors added that anecdotal evidence and consumer testimonials are not considered competent and reliable scientific evidence.

FTC v. On Point Global LLC (government-services websites)
On Point Global: Verdict and Order Following Non-Jury Trial, No. 19-25046-Civ-Scola (S.D. Fla. Nov. 15, 2021)
The FTC alleged that the defendants operated various websites that deceptively caused consumers to believe they could apply for, or complete transactions related to, government services or benefits, and the court held the websites were deceptive acts or practices in violation of Section 5(a). Source: FTC v. On Point Global LLC, No. 19-25046-Civ-Scola (S.D. Fla. Nov. 15, 2021) When the case reached the contempt phase, the court found significant and credible anecdotal evidence that many of the customers either suffered no harm or were wholly satisfied with their experiences with the Defendants. Source: FTC v. On Point Global LLC, No. 19-25046-Civ-Scola (S.D. Fla. Nov. 15, 2021)
Outcome. The court set the starting point for contempt damages at $102,768,235.47, then, because of the anecdotal evidence of satisfaction, chose a claims process so that unsatisfied consumers could be fully compensated. Source: FTC v. On Point Global LLC, No. 19-25046-Civ-Scola (S.D. Fla. Nov. 15, 2021) It rejected the argument that consumers who did not complain were satisfied, because failing to complain is not the equivalent to satisfaction. Source: FTC v. On Point Global LLC, No. 19-25046-Civ-Scola (S.D. Fla. Nov. 15, 2021)
FTC v. Enforma Natural Products, Inc. (weight-loss products)
Memorandum in Support of Plaintiff's Application for an Order to Show Cause Why Defendants Enforma Natural Products, Inc. and Andrew Grey and Nonparty Michael Ehrman Should Not Be Held in Civil Contempt
Enforma advertised that the Enforma System works because millions of consumers had purchased it and lost 10, 20, 30, 40, 50, even 100 pounds. Source: Memorandum in Support of Plaintiff's Application for an Order to Show Cause Why Defendants Enforma Natural Products, Inc. and Andrew Grey and Nonparty Michael Ehrman Should Not Be Held in Civil Contempt (quoting FTC, Dietary Supplements: An Advertising Guide for Industry) What it gave the Commission was a list of approximately 1,100 purchasers, many but not all of whom claimed to have lost some weight. Source: Memorandum in Support of Plaintiff's Application for an Order to Show Cause Why Defendants Enforma Natural Products, Inc. and Andrew Grey and Nonparty Michael Ehrman Should Not Be Held in Civil Contempt (quoting FTC, Dietary Supplements: An Advertising Guide for Industry)
Outcome. The Commission argued that purchasers' claimed weight loss is mere anecdotal evidence, which cannot constitute competent and reliable scientific substantiation of the claims. Source: Memorandum in Support of Plaintiff's Application for an Order to Show Cause Why Defendants Enforma Natural Products, Inc. and Andrew Grey and Nonparty Michael Ehrman Should Not Be Held in Civil Contempt (quoting FTC, Dietary Supplements: An Advertising Guide for Industry) It also argued that the existing order requires competent and reliable scientific evidence and does not countenance substantiation through mere anecdote. Source: Memorandum in Support of Plaintiff's Application for an Order to Show Cause Why Defendants Enforma Natural Products, Inc. and Andrew Grey and Nonparty Michael Ehrman Should Not Be Held in Civil Contempt As a civil contempt remedy, it asked the court to require the defendants to account for and turn over all gross revenues from these products and the Enforma System received after May 11, 2000.

FTC v. QT, Inc. (Q-Ray ionized bracelet)
QT and R-Ray Memorandum Opinion and Order
Que Te Park relied on anecdotal evidence to substantiate pain-relief claims for the Q-Ray bracelet, basing his view on personally meeting 8,100 consumers. Source: FTC v. QT, Inc., Memorandum Opinion and Order That group was only about one percent of all Q-Ray bracelet purchasers. Source: FTC v. QT, Inc., Memorandum Opinion and Order Many of the warranty cards the company relied on also gave buyers an incentive to submit testimonials, because they notified consumers that they would receive a 20% discount on their next purchase if they did. Source: FTC v. QT, Inc., Memorandum Opinion and Order A study from China fared no better: according to Dr. Hochberg, it had only five participants, did not appear to have been blinded in any way, and was not placebo-controlled, so at best it could be considered anecdotal evidence. Source: FTC v. QT, Inc., Memorandum Opinion and Order The company's infomercials, which were built on user testimonials, carried small-print statements such as "Individual results may vary," and those disclaimers did not alter the strong net impression conveyed by the prolific use of consumer testimonials and the host's sales pitch. Source: FTC v. QT, Inc., Memorandum Opinion and Order
Outcome. The court found inadequate scientific substantiation for the claim that the Q-Ray bracelet provides immediate, significant or complete pain relief. Source: FTC v. QT, Inc., Memorandum Opinion and Order It also noted that the company had at least a 25% refund request rate from dissatisfied purchasers, and that $27,132,249 was refunded to consumers between January 1, 2000, and June 30, 2003.

In re Daniel Chapter One (dietary supplements marketed for cancer)
Initial Decision Filed by Chief Administrative Law Judge, D. Michael Chappell [Public Record Version]
The respondents' advertising represented that the challenged products, individually or collectively, prevent, treat, or cure cancer, inhibit tumors, or ameliorate the adverse effects of chemotherapy or radiation. Source: Initial Decision Filed by Chief Administrative Law Judge, D. Michael Chappell [Public Record Version], n.5 The judge treated the respondents' testimonials as objective claims that the products inhibit tumors or are otherwise effective in the treatment of cancer. Source: Initial Decision Filed by Chief Administrative Law Judge, D. Michael Chappell [Public Record Version], n.5 Those testimonials did not constitute valid scientific evidence because, among other reasons, it could not be confirmed that the speakers had cancer. Source: Initial Decision Filed by Chief Administrative Law Judge, D. Michael Chappell [Public Record Version], n.5
Outcome. The initial decision found the company and its overseer liable for violating Sections 5(a) and 12 of the FTC Act. Source: Initial Decision Filed by Chief Administrative Law Judge, D. Michael Chappell [Public Record Version], n.5 The order attached to it prohibits representations that a health-related product prevents, treats, or cures cancer unless the representation is true, non-misleading, and, at the time it is made, the respondents possess and rely upon competent and reliable scientific evidence that substantiates it. Source: Initial Decision Filed by Chief Administrative Law Judge, D. Michael Chappell [Public Record Version], n.5
FTC v. the sellers of Grey Defence (gray-hair supplement)
Order on Cross Motions for Summary Judgment
The sellers pointed to their own "Observational Survey" as support for their claim that Grey Defence reverses or prevents gray hair, and the court found that it did not provide sufficient substantiation for their advertising claims. Source: Order on Cross Motions for Summary Judgment (Grey Defence) That survey consisted of feedback from twenty Grey Defence users out of the 100 contacted. Source: Order on Cross Motions for Summary Judgment (Grey Defence) The court found it clear, even to the Court, that the survey could not be characterized as a well-designed or controlled scientific study. Source: Order on Cross Motions for Summary Judgment (Grey Defence)
Outcome. The court found the efficacy claim unsubstantiated, so the sellers lacked a reasonable basis for it. Source: Order on Cross Motions for Summary Judgment (Grey Defence) In reaching that result, it noted Dr. Cotsarelis's statement that anecdotal evidence, such as reports from participants, is insufficient to prove a product's efficacy. Source: Order on Cross Motions for Summary Judgment (Grey Defence)
United States v. B4B Corp. (COVID-19 herbal tea)
Complaint for Civil Penalties, Permanent Injunction, Monetary Relief, and Other Relief
The complaint alleged that the defendants sold Earth Tea for $60 per 16-ounce bottle. Source: Complaint for Civil Penalties, Permanent Injunction, Monetary Relief, and Other Relief (Earth Tea) It further alleged that since at least April 2020 they advertised it to prevent, mitigate, treat, or cure COVID-19. Source: Complaint for Civil Penalties, Permanent Injunction, Monetary Relief, and Other Relief (Earth Tea) According to the complaint, the defendants purported to possess anecdotal evidence from customers and relied on a 15-person purported study that they stated was conducted in India. Source: Complaint for Civil Penalties, Permanent Injunction, Monetary Relief, and Other Relief (Earth Tea)
Outcome. The complaint alleged that neither the purported anecdotal reports nor the small, unpublished study suffices as competent and reliable scientific evidence to substantiate the claimed health benefits. Source: Complaint for Civil Penalties, Permanent Injunction, Monetary Relief, and Other Relief (Earth Tea) It added that the anecdotal reports are not documented and, even if accurate, do not constitute competent and reliable human clinical evidence that consuming Earth Tea caused any improvement in COVID-19 symptoms. Source: Complaint for Civil Penalties, Permanent Injunction, Monetary Relief, and Other Relief (Earth Tea)
Exposure
A business that rests health claims on anecdotes faces an injunction first. Once a challenged practice is found to be prohibited by Section 5 of the FTC Act, the appropriate remedy is an order requiring the respondents to cease and desist from it. Source: Initial Decision Filed by Chief Administrative Law Judge, D. Michael Chappell [Public Record Version], n.5 In the Sagee settlement that took the form of a permanent injunction that conditions future health, performance, and efficacy claims on competent and reliable scientific evidence. Source: Stipulated Final Judgment and Order for Permanent Injunction and Monetary Relief (Sagee) The order attached to the Daniel Chapter One initial decision also reaches beyond the challenged products, because it covers any dietary supplement, food, drug, or other health related product, service, or program. Source: Initial Decision Filed by Chief Administrative Law Judge, D. Michael Chappell [Public Record Version], n.5
Money exposure grows when a seller already operates under an order. In On Point, the court put the starting point for contempt damages at $102,768,235.47 and held the defendants jointly and severally liable for an amount not to exceed that figure, with any lesser final amount to be set after a claims process. Source: FTC v. On Point Global LLC, No. 19-25046-Civ-Scola (S.D. Fla. Nov. 15, 2021) In the Enforma matter, the Commission argued that where consumers are induced to buy a product through deceptive means, a contempt sanction in the amount of gross sales of the product is appropriate. Source: Memorandum in Support of Plaintiff's Application for an Order to Show Cause Why Defendants Enforma Natural Products, Inc. and Andrew Grey and Nonparty Michael Ehrman Should Not Be Held in Civil Contempt The B4B complaint, for its part, invoked authority to award monetary civil penalties of up to $46,517 for each violation of Section 5(a) of the FTC Act pursuant to the CCPA. Source: Complaint for Civil Penalties, Permanent Injunction, Monetary Relief, and Other Relief (Earth Tea)
Evidence of happy customers does not erase liability, though it can affect the size of a monetary sanction. The On Point court found significant and credible anecdotal evidence that many customers were satisfied, concluded that imposing over $100,000,000 in sanctions would be inequitable, and chose a claims process for unsatisfied consumers. Source: FTC v. On Point Global LLC, No. 19-25046-Civ-Scola (S.D. Fla. Nov. 15, 2021) Refund volume can cut the other way, as in the Q-Ray matter, where the company acknowledged at least a 25% refund request rate from dissatisfied purchasers. Source: FTC v. QT, Inc., Memorandum Opinion and Order Downstream sellers are exposed too, since a notice distributed under the Superior Products injunction warns that failure to follow any provisions of the order that apply to a distributor could result in civil or criminal sanctions. Source: Permanent Injunction, FTC v. Superior Products International II, Inc., No. 2:20-cv-2366-HLT-GEB (D. Kan.), Attachment A A notice sent to Seasilver distributors likewise warns that noncompliance may subject them to civil or criminal penalties.
