stubbornness

This term describes a rigid adherence to a position or state, often carrying a negative connotation of irrationality or obstinacy. When applied to people, it suggests a willful refusal to yield, regardless of the logic or evidence presented. In a non-human context, the word describes a persistent or resistant quality, such as a stain that will not fade or a disease that resists treatment. In these cases, the connotation shifts from a personality flaw to a frustrating physical property of endurance.
