The fallacy occurs when it is argued that something is good or correct simply because it has been done that way for a long time. The central premise of this reasoning is that a long-standing practice or belief is inherently superior to a new one. For instance, asserting that a particular social custom is right merely because it has been practiced for generations exemplifies this flawed line of thought. This assumes longevity equates to validity, neglecting potential flaws or changed circumstances that might render the tradition obsolete or even harmful.
Recognizing this type of reasoning is important for critical thinking because it can hinder progress and perpetuate outdated ideas. While traditions can offer valuable insights and stability, they should be critically examined and adapted when necessary. A reliance on past practices without considering their current relevance can lead to stagnation and resistance to beneficial change. Historically, many societal advancements have been achieved by questioning and ultimately abandoning long-held, but ultimately detrimental, customs.
