Introduction
A common response in product safety disputes is: “Millions of customers use this product without problems.” The statement may be true, but as an argument it can become a red herring. A large user base does not by itself answer whether a smaller group faces a serious and foreseeable danger. In safety analysis, risk depends not only on how often an event occurs but also on how severe the outcome can be. A hazard that affects one user in a million may be acceptable if the consequence is minor inconvenience; the same frequency may be unacceptable if the consequence is death, permanent disability, or severe injury.

Within discussions of logical fallacies, the problem arises when scale is used as a substitute for addressing the specific hazard. The relevant question is not how many people were unharmed. It is whether the exposed group, the mechanism of injury, and the severity of the outcome justify design changes, warnings, repairs, or recalls.
Why Large User Counts Feel Persuasive
Large numbers create a powerful psychological impression. If a company can point to millions of sales, years of use, or a vast customer base, many people instinctively conclude that the product must be safe. That intuition is not entirely unreasonable. Widespread use often does provide useful information about reliability and performance.
The difficulty is that aggregate success can hide concentrated risks. A product can work exactly as intended for 99.99% of users while still creating an unacceptable danger for a predictable minority. Safety investigations therefore look beyond overall popularity and ask more focused questions:
- Who is exposed to the hazard?
- Under what conditions does the hazard appear?
- Can users reasonably detect or avoid it?
- What is the likely severity of injury if it occurs?
- Are vulnerable groups disproportionately affected?
When those questions remain unanswered, citing customer scale can distract from the issue under examination. The argument shifts from “Is this hazard acceptable?” to “Many people like the product,” which is not the same claim.
When Rare Injuries Still Justify Safety Action
Product safety decisions are rarely based on frequency alone. Regulators, engineers, and courts commonly evaluate risk as a combination of probability and severity. A low-probability event may still require intervention if the consequences are catastrophic. [www.cedengineering.com]cedengineering.comwww.cedengineering.com Ethics: An Alternative Account of the Ford Pinto Casewww.cedengineering.comEthics: An Alternative Account of the Ford Pinto CaseSeptember 22, 2020 — by M Rossow · 2015 · Cited by 3 — “A thin…
Consider the difference between two hypothetical defects:
- A defect causes a cosmetic scratch in one out of every 100,000 uses.
- A defect causes a fatal injury in one out of every 100,000 uses.
The frequency is identical. The severity is not. Most safety frameworks treat these situations very differently because the consequences differ dramatically.
This is why safety debates often focus on the exposed group rather than the total customer population. If a hazard threatens infants, children, patients, or people who cannot easily recognise the danger, even a relatively small number of incidents may carry substantial weight. Regulators frequently act before injuries become common precisely because waiting for larger numbers would mean accepting preventable harm.
What the Peloton Treadmill Dispute Revealed
The controversy surrounding the Peloton Tread+ treadmill illustrates the tension between scale claims and severe low-frequency hazards.
The issue was not whether thousands of customers exercised safely. The concern was a specific mechanism: reports that children, pets, and objects could be pulled underneath the rear of the machine. The U.S. Consumer Product Safety Commission (CPSC) warned of serious risks including fractures and death. Reports included a child’s death and multiple injuries involving children. Peloton ultimately recalled the product, and the company later agreed to pay a civil penalty related to reporting and recall issues.

From a logical standpoint, “many owners use the treadmill safely” did not resolve the underlying question. The relevant inquiry was whether the design created an unreasonable risk for a smaller, identifiable group of users and bystanders. The size of the satisfied customer base could not answer that design-specific concern.
The Rock ‘n Play Sleeper and the Limits of Popularity
The Fisher-Price Rock ‘n Play sleeper provides another example of why sales volume and customer adoption are not decisive safety arguments.
Millions of units were sold, making the product commercially successful. Yet regulators and safety advocates became increasingly concerned about infant fatalities associated with the sleeper. The CPSC’s recall notices eventually involved roughly 4.7 million units, and later reports documented additional deaths after the initial recall. The concern centred on a specific risk mechanism involving infant positioning and suffocation hazards, not on whether most purchasers reported positive experiences.

The case demonstrates an important principle: a product can achieve enormous market penetration while still presenting a severe hazard to a subset of users. Popularity and safety are related questions, but they are not identical.
Why Safety Analysis Focuses on the Exposed Group
A key weakness in scale-based arguments is that they often treat all users as equally relevant.
Suppose ten million people use a product. If a hazard affects only infants, children, or a particular usage scenario, the true population at risk may be far smaller than ten million. Looking only at total sales can dilute attention away from the group that actually faces the danger.
A more informative analysis asks: [jstor.org]jstor.orgJSTORCorporate Risk Analysis: A Reckless Act?by WK Viscusi · 2000 · Cited by 286 — the internal Ford Pinto safety documents has been foll…
Who experiences the incidents?
Are injuries concentrated among a particular age group, body type, medical condition, or use pattern?
How severe are the outcomes?
Do incidents produce minor injuries, hospitalisations, permanent impairment, or fatalities?
Is the hazard foreseeable?
Could engineers reasonably anticipate the circumstances that lead to injury?
Can ordinary users avoid the risk?
If preventing harm requires perfect vigilance, the design itself may deserve scrutiny.
These questions address the hazard directly. Raw customer counts do not.
The Ford Pinto Debate and Severity-Based Reasoning
The Ford Pinto remains one of the most discussed examples in debates about acceptable risk. Although details of the historical narrative are often simplified in popular retellings, the controversy helped crystallise an important safety principle: evaluating risk requires considering both probability and severity rather than frequency alone.

Critics argued that the existence of many uneventful vehicle trips did not eliminate concern about a fuel-system design that could contribute to especially severe outcomes in certain rear-end collisions. The enduring lesson is not that every rare event demands drastic action. Rather, it is that a low-frequency hazard cannot be dismissed merely because most users never encounter it.
When the potential consequence is death or severe injury, decision-makers are expected to examine whether the risk is foreseeable, reducible, and reasonable—not simply whether it is uncommon.
Questions That Reveal the Real Issue
When a company responds to a safety concern by emphasising customer scale, several questions help determine whether the argument is relevant or merely distracting:
- What is the specific hazard being discussed?
- How serious are the potential injuries?
- Which users are actually exposed to the danger?
- Would the affected group consider the risk acceptable if fully informed?
- Can the hazard be reduced through design changes, repairs, or warnings?
- Does the company have evidence addressing the hazard itself, or only evidence of broad customer adoption?
If the answer relies primarily on sales figures, user counts, or popularity metrics, the response may be sidestepping the core safety question.
Can Big Numbers Hide a Serious Hazard?
Yes. Large user counts can provide useful context, but they cannot settle a dispute about a severe low-frequency hazard. Millions of successful uses may show that a product performs well for most people. They do not automatically show that the remaining risk is acceptable.
In product safety debates, the decisive evidence usually concerns the exposed group, the injury mechanism, the severity of outcomes, and the feasibility of reducing the danger. When those issues remain unresolved, appeals to customer scale risk functioning as a red herring—drawing attention to impressive numbers while leaving the central safety question unanswered.
