Fallible vs. Infallible — What's the Difference?

Fallible describes humans or systems prone to errors, reflecting the inherent imperfections in human nature and most human-made systems. On the other hand, infallible is used to describe someone or something that is incapable of making mistakes, often in a context that requires absolute trust, such as religious doctrines or theoretical models.

In everyday language, being fallible is a common human trait, suggesting humility and the recognition of one's limitations. Whereas, claiming infallibility is typically reserved for figures or entities in positions of significant authority or sanctity, such as religious leaders or certain philosophical ideals.

The concept of fallibility is crucial in fields like science and philosophy, where assumptions must be continuously tested and questioned. In contrast, infallibility often holds a foundational role in religious contexts, where certain texts or decrees are considered beyond doubt or error.

Legal systems, too, operate under the assumption of fallibility; hence, mechanisms for appeal and review exist. Conversely, doctrines considered infallible are expected to be adhered to without questioning, highlighting a stark contrast in approach and application between the two terms.

In literature, characters' fallibility often drives narrative conflict and character development. In contrast, infallible characters might be portrayed as static or divine, serving different narrative purposes and themes.
