Appeal to Tradition: Why "We've Always Done It This Way" Is Not a Reason

Somewhere in the history of every bad idea is a long run of unbroken practice. The appeal to tradition — known in Latin as argumentum ad antiquitatem — is the fallacy of treating the age or longevity of a practice, belief, or institution as evidence of its correctness, superiority, or moral legitimacy. The argument's form is disarmingly simple: "We have always done it this way; therefore, it is right to continue doing it this way." The error is equally simple: duration is not validation.

The Logical Structure

The fallacy takes a recognisable form:

1. Practice/belief X has been followed for a long time (or since ancient times).
2. Therefore, X is correct, good, or should be continued.

The second step does not follow from the first. A practice can persist for centuries due to institutional inertia, social conformity, lack of alternative knowledge, political enforcement, or simple habit — none of which constitute evidence for its truth or value. The question "is this practice good?" remains entirely open after we establish that it is old.

Philosopher Nicholas Rescher identified the core error as a confusion between chronological precedence and epistemic or moral authority. Age tells us when something originated; it says nothing about whether that origin was wise, the perpetuation is justified, or the practice survives on merit rather than momentum.

The Counterexamples Are Devastating

The most immediate refutation is historical enumeration. Medical practice provides some of the starkest examples. Bloodletting — the removal of blood to restore humoral balance — was practised for over two thousand years across multiple independent medical traditions: Greek, Roman, Chinese, Islamic, European. Its longevity was not evidence of efficacy; it was killing patients. George Washington may have been hastened to death by the repeated bloodletting his physicians administered in 1799, following a tradition that was already ancient. The tradition was wrong. It had always been wrong.

Female genital mutilation is practised in parts of Africa, the Middle East, and Asia as a cultural and sometimes religious tradition going back thousands of years. Its defenders frequently cite its traditional status as justification. The age and cultural embeddedness of the practice are real. They constitute no argument for its continuation, as the documented health consequences make clear.

The geocentric model of the solar system was the astronomical consensus for roughly two millennia. Burning heretics and executing apostates was a long-established institutional practice of multiple major religions. Slavery was a universal feature of organised societies from the earliest records. The traditional status of each of these is historically unambiguous. Their wrongness is equally unambiguous.

Why Traditions Persist: The Real Mechanisms

Understanding why traditions endure — even harmful or incorrect ones — is essential to seeing why longevity cannot be treated as evidence of merit. Several mechanisms explain persistence independent of value:

Institutional inertia. Organisations develop procedures, hierarchies, and cultures that are costly to change. Medical protocols, legal procedures, educational curricula, and bureaucratic processes persist long after the original rationale has dissolved, simply because changing them requires effort and coordination that no individual participant can supply unilaterally.

Path dependence. Early decisions constrain later ones in ways that lock in suboptimal outcomes. The QWERTY keyboard layout was designed to prevent typewriter jams — a problem that has not existed since the 1970s. The layout persists not because it is optimal but because billions of people have learned it and the switching costs are vast. Path dependence explains many persistent practices: not because they were best, but because they got there first.

Status quo bias. Humans systematically prefer the existing state of affairs over alternatives, even when the alternatives are demonstrably superior. Research by William Samuelson and Richard Zeckhauser documented this bias: people require much larger gains from change to overcome their preference for what already exists, compared to what rational expected-value calculation would predict. Tradition benefits from status quo bias at civilisational scale.

Social conformity and signalling. Following tradition signals group membership, respect for elders, and social reliability. Deviating from tradition signals the opposite. In cultures where deviation is costly and conformity is rewarded, traditions can persist through social enforcement long after any functional justification has evaporated.

The Conservative Insight: Traditions Aren't Worthless

A sophisticated appeal to tradition must be distinguished from the simple fallacy. Edmund Burke's conservatism, and the philosophical tradition following it, makes a more nuanced claim: traditions represent accumulated practical wisdom that may not be articulable in explicit principles but that has been tested against the reality of human social life across generations. Chesterton's Fence captures this: before you remove a fence, you should understand why it was built. If you cannot explain the reason, you probably shouldn't remove it.

This is not the same as saying traditions are correct because they are old. It is saying: there may be non-obvious reasons for traditional practices, and epistemic humility warrants caution before discarding them. This is a reasonable empirical claim about the evidential weight of survival — not a logical argument that age equals correctness.

The distinction matters. The Burkean position says: "This tradition has survived; we should investigate why before discarding it." The fallacious position says: "This tradition has survived; therefore it is correct and should not be questioned." The first is cautious empiricism. The second is the appeal to tradition fallacy.

Institutional Religion and Cultural Practice

Religion provides the highest-stakes arena for appeals to tradition. Many religious practices and doctrines are defended primarily by their traditional status — they are authoritative because they are ancient, because they were revealed to ancient figures, or because they have been practised continuously for millennia. The theological complexities here exceed this article's scope, but the logical point is clear: the age of a religious claim does not settle its truth, and the age of a religious practice does not settle its moral status.

Cultural practices more broadly — dietary restrictions, dress codes, gender roles, marriage customs, child-rearing norms — are frequently defended by tradition. "This is our culture" can serve as genuine contextual explanation, or it can serve as a substitute for ethical evaluation. When it substitutes, the appeal to tradition fallacy is operating: the cultural embeddedness of a practice is treated as its justification.

Legal and Political Applications

Common law systems are partly founded on precedent — previous judicial decisions constrain current ones, providing stability and predictability. This is sometimes misread as an institutional appeal to tradition, but it is a different thing: the rule of precedent reflects values of consistency, fairness, and the rule of law rather than the claim that older decisions are more correct. Courts regularly overturn precedent when they conclude it was wrongly decided.

Political conservatism often deploys tradition as a policy argument: existing social arrangements have demonstrated their viability and should not be disrupted by untested alternatives. This can be a legitimate empirical claim (proven arrangements have lower variance) or an appeal to tradition fallacy (existing arrangements are good because existing). Distinguishing between these requires examining whether an independent case for the arrangement's value is being offered or merely its longevity asserted.

How to Counter It

• Apply Chesterton's Fence productively. "Why has this tradition persisted? What specific function does it serve? Is that function still relevant?" If the tradition cannot be functionally defended beyond its age, the case collapses.
• Supply counterexamples. "Bloodletting was a two-thousand-year-old tradition. Female genital mutilation is ancient. Age has not protected these practices from being correctly evaluated as harmful."
• Separate persistence from merit. "You've established that this practice is old. That tells us something about how it has spread and survived — it doesn't tell us whether it is good."
• Request an independent argument. "Setting aside its traditional status, what is the case for this practice on its own merits?"
