Sufficiency as a logical fallacy

Ross Woods, 2020

Standards often require that something be “sufficient.”

Simply put, “sufficient for what”?

It is a fallacy to state either that something is sufficient or insufficient without applying a criterion. The criterion should be either explicitly stated or necessarily implied. (Without a criterion, an assertion of either "sufficient" or “insufficient” is only an arbitrary statement of personal preference.)

This also applies to other words such as adequate, inadequate, enough, too, and excessive.

It is a variation of the missing premise fallacy.
