In literature, tenaciousness is often depicted as a quality that can be both admirable and burdensome. Authors use the term to evoke a sense of persistence—whether in a character’s unwavering determination, as seen in references to steadfast purpose and endurance [1, 2], or in the intransigence of opinions that cling despite reason [3, 4]. It is equally employed to highlight both the positive aspects of resoluteness, such as in feats of valor or the holding fast to one’s dignity [5, 6], and its negative dimensions, where an obstinate grip on error or sentiment becomes oppressive [7, 8]. This multifaceted use enriches characters and settings, presenting tenaciousness as a double-edged trait that can drive individuals to both greatness and downfall.
