Without taking a strong theoretical stance on the terminological boundary between ambiguity and vagueness, we suggest that, at least when considered as persuasion devices, they are quite different and almost opposite phenomena. We suggest that vagueness is effectively persuasive in that it can specifically divert epistemic vigilance from questionable or unpleasant contents. Ambiguity, conversely, encodes multiple meanings drawing additional attention to the message. We support such claims through examples from markedly persuasive texts and through the results of a self-paced reading experiment revealing differences between contextually precise vague expressions (VE), contextually non-precise VE, and precise expressions.
