"Ignorance per se is not nearly as dangerous as ignorance of ignorance"
About this Quote
The phrase "ignorance of ignorance" is doing double duty. It’s not just a personal flaw; it’s a civic hazard. A person who knows they don’t know might ask questions, consult expertise, hedge their claims. A person who doesn’t know they don’t know tends to speak in absolutes, interpret doubt as weakness, and treat complexity as a conspiracy. Harris is diagnosing the psychology behind bad certainty: the confidence that comes not from understanding, but from the absence of friction with reality.
Context matters here. Harris wrote in an era when mass media was consolidating its power to shape public common sense - network television, Cold War propaganda, advertising’s gloss of authority. Journalism’s job, ideally, is to puncture false confidence and model intellectual humility. Harris is warning that the real enemy isn’t the uninformed; it’s the un-self-suspicious. The subtext is a quiet rebuke to every institution and personality that profits from making people feel sure, especially when they shouldn’t.
