In literature, "fatuous" is frequently invoked to denote a kind of hollow, foolish behavior or empty self-satisfaction. Writers apply the term to characters whose actions or expressions betray a lack of depth, as when a gentleman smiles in a way that appears both insincere and absurdly self-complacent [1, 2]. In other contexts, it describes misguided impulses—ranging from capricious emotional outbursts [3] to a vacuous sense of curiosity that leads characters into dubious pursuits [4]. Whether denoting a superficial optimism or an ironic self-reflection on one’s own conceited nature [5, 6], the word serves as a subtle critique of pretension and vacuity in human conduct.
