faultfinding

This term carries a strong negative connotation, implying a pedantic or obsessive focus on errors rather than a constructive desire for improvement. It suggests a personality trait or a behavioral pattern that is irritating and demoralizing to others, often associated with micromanagement or a lack of empathy.

When used as a noun, it describes the general activity of criticizing. When used as an adjective, it describes the inherent nature of a person or their attitude. It is distinct from "critical," which can be objective or helpful; "faultfinding" is almost always perceived as petty or unfair.
