infallibility

This term conveys an absolute sense of perfection and certainty, often carrying a heavy weight of authority or divine sanction. It is rarely used to describe a person's general skill, but rather to describe a state of being structurally or spiritually incapable of error. In secular contexts, it often appears in a critical or ironic sense to highlight the arrogance of someone who believes they cannot be wrong.

As an abstract quality, this noun is uncountable. It describes a conceptual state rather than a discrete object, meaning it cannot be pluralized or counted with numbers. To refer to specific instances of this quality, one must use partitive constructions such as a claim of infallibility or a sense of infallibility.
