In literature, “tactless” is commonly deployed to characterize characters or actions that lack the finesse expected in social interactions. Authors use the term to signal moments when honesty or candor crosses the line into insensitivity—as when a diplomat ruefully admits, “I see I've been tactless again” [1], or when a character’s blunt remarks expose a deeper flaw in character [2]. It is also invoked to underline the conflict between good intentions and poor execution, such as a speaker’s inability to soften harsh truths [3] or a social misstep that disrupts cordiality [4]. At times, the term conveys a nuanced interplay between admirable honesty and social awkwardness, as seen in portrayals of individuals who, though straightforward, are unable to temper their remarks [5] or who inadvertently offend through overzealous frankness [6]. Through such varied usage, “tactless” underscores the perennial tension between sincerity and decorum in human relations [7][8].
