obstinacy

This term carries a strong negative connotation, suggesting a rigid, irrational refusal to yield. It describes a psychological state of stubbornness that is often perceived as obstructive or frustrating to others, rather than a principled stand. It is typically used in formal or literary contexts to describe a character flaw or a systemic deadlock.

As an uncountable noun, it refers to an abstract quality. It cannot be pluralized or counted as individual units; instead, it is measured in degree, often paired with adjectives like sheer, blind, or dogged to emphasize the intensity of the refusal.
