Appeal to Tradition

Examples

A new hire suggests a change to a weekly process.

Nadia: “Could we submit these reports through the shared form instead of printing and scanning them?” Team lead: “We’ve filed reports this way for twenty years. If it were broken, we’d have changed it by now.”

Twenty years of a process shows that it hasn’t been fatal — not that it’s the best option, or even a good one. Nobody in the story has actually compared the two methods; the age of the habit is doing all the arguing.

The same move appears in online arguments about customs:

Comment: “Why do we still write dates as month/day/year here? Most of the world doesn’t.” Reply: “Because that’s how it’s always been written. It’s tradition, leave it alone.”

“It’s tradition” describes the practice’s history, but it isn’t a reason the practice is better than the alternative.

Why the reasoning fails

Appeal to tradition treats the age or persistence of a practice as evidence that the practice is correct or optimal. But a practice can survive for reasons that have nothing to do with its quality — inertia, the effort of changing it, or simply nobody questioning it. Longevity shows that something was tolerable enough not to be replaced, which is a much weaker claim than this is the best way to do it. The reasoning fails because “old” and “good” are separate questions that need separate evidence, and pointing to how long something has lasted answers neither.

How to respond

• Ask what tradition is standing in for: “Setting the history aside, what makes this the best approach for us now?”
• Separate the two questions: “I’m not saying it’s bad because it’s old — I’m asking whether it still works better than the alternative.”
• Propose a direct comparison: “Could we test the new form on one team before deciding?”
• Let tradition break a genuine tie. When two options are otherwise equally good, sticking with the familiar one is often the sensible, low-cost choice — the fallacy is using tradition as the whole argument, not as a tiebreaker.
