is speech useless

Speech can be ineffective or harmful in several ways. First, misinformation and disinformation spread false beliefs: speakers may be mistaken (misinformation) or deliberately deceptive (disinformation), leading audiences to act on wrong information with real-world harms (Lewandowsky et al., 2017). Second, manipulation exploits cognitive biases and emotional triggers to change attitudes or behavior without informed consent, undermining autonomy and democratic deliberation (Sunstein, 2001). Third, speech can be merely performative—utterances that signal identity or virtue without producing meaningful change (Butler, 1997)—which creates the appearance of action while leaving underlying problems unaddressed. Finally, certain speech acts can silence or marginalize others, entrenching power imbalances rather than fostering understanding. References: - Lewandowsky, S., Ecker, U. K. H., & Cook, J. (2017).
