--- - title: Accident fallacy - categories: [generalization] - synonyms: [fallacy of the accident, secundum quid, a dicto simpliciter, riding on principles] - related: [generalization/hasty_generalization, generalization/overwhelming_exception, rhetoric/slippery_slope, relevance/false_dilemma] - main_article: - main_article_de: --- # Accident fallacy **Core claim:** A generally valid rule (law, principle, norm) is applied rigidly to a specific case in which special circumstances would warrant an exception. ## Applies when - A universally stated rule or principle is enforced in a situation that clearly falls outside its intended scope or prerequisites. - The argument treats the rule as absolute and ignores relevant contextual factors (emergency, self-defence, disproportionate harm) that would justify deviating from it. - An automated system applies a rule mechanically without accounting for edge cases or exceptions (e.g., traffic cameras fining an ambulance, content filters blocking harmless words). - The insistence on the rule is presented as morally or legally binding even though applying it here would produce an obviously absurd or harmful outcome. ## Notes - The term "accident" here derives from Latin *accĭdens* = "circumstance, non-essential aspect", it should not be interpreted in the modern sense as in "traffic accident". - This fallacy is particularly relevant for *moral* predicaments: It describes a situation where a *deontological* approach (following rules strictly) was used in a situation where a *consequentialist* one (decisions based on the outcome) would have been more appropriate. ## Does NOT apply when - A rule is applied within its intended scope and no special circumstances exist that would justify an exception. - The speaker explicitly acknowledges possible exceptions but provides a reasoned argument for why none apply in this specific case. - The rule being discussed is genuinely absolute (e.g., logical axioms, mathematical theorems) with no legitimate domain of exception. ## Commonly confused with - **[Hasty generalization](generalization/hasty_generalization)** ([MD](generalization/hasty_generalization.md)) – the *reverse* direction: a universal rule is derived from too few or unrepresentative cases. Ask: is the error about *creating* an unjustified general rule (→ hasty), or *applying* a well-founded rule where it shouldn't reach (→ accident)? - **[Overwhelming exception](generalization/overwhelming_exception)** ([MD](generalization/overwhelming_exception.md)) – a general claim that is technically true but so riddled with exceptions as to be practically useless. Ask: is the problem that the *generalisation itself* is misleading because of too many exceptions (→ overwhelming), or that a *specific case* is being forced under a rule despite clear exceptional circumstances (→ accident)? - **[(Dogmatic) coherentism](knowledge/coherentism)** ([MD](knowledge/coherentism.md)) — claims something is true or real because it fits an existing narrative, ideology, or theoretical system. Ask: is the argument that a general rule should be applied, even when an exception is warranted (→ accident), or that it should be interpreted in a way consistent with a system or worldview, even though there is evidence to the contrary (→ coherentism)? These often overlap! - **[Appeal to authority](relevance/authority/index)** ([MD](relevance/authority/index.md)) – the *validity* of a rule is justified solely by its source (a law, an institution, an expert or a tradition), rather than by its content or applicability. Ask: is the error about *why the rule is considered binding at all* (→ authority), or about whether a well-founded rule is being applied *outside its intended scope* in a specific case (→ accident)? The latter is often the result of the earlier fallacy. ## Examples > **Input:** "It's illegal to injure someone, so a surgeon performing emergency surgery is committing a crime." > **Output:** The general prohibition against injuring others does not cover situations where the injury is necessary to save a life. Emergency surgery is a recognised exception. > **Input:** "The content filter flagged my post, so it must contain offensive language." > **Output:** Automated filters apply a simple keyword rule and cannot distinguish context (e.g., place names, medical terms). The flag is a signal to review, not proof that the content is actually offensive – a human should check before acting on it. > **Input:** "You must always obey your superiors' orders; refusing is never justified." > **Output:** The duty of obedience in hierarchical organisations has clear limits: orders that are manifestly illegal or violate fundamental moral principles (e.g., killing civilians) must be refused, regardless of rank or institutional pressure.
