The word "indubitable" has been deployed in literature as a marker of undeniable truth or clarity about a fact, observation, or perception. In many texts—from Freud’s observation that unpleasant impressions can be readily forgotten [1] to Jane Austen’s commentary on social judgments in Emma [2]—the term underscores an assertion that leaves little room for debate. Its use spans both scientific and literary discourse, where it often qualifies evidence as self-evident, such as in discussions of observable phenomena in sociology and criminal psychology [3, 4, 5]. Additionally, the word appears in the works of authors like Carlyle, Hawthorne, and Dickens, where it not only lends an air of certainty to historical events or character traits [6, 7, 8] but also subtly conveys the persuasive power of ostensibly irrefutable details, as seen in Jefferson’s foundational document [9].
