"It is dangerous to be sincere unless you are also stupid"
About this Quote
The barb is in “unless you are also stupid.” Stupidity functions as a kind of diplomatic immunity. If you’re simple-minded, sincerity reads as innocence; people forgive the bluntness because there’s no threat of calculation. Intelligence, by contrast, makes sincerity suspicious and therefore dangerous. A smart person speaking plainly can expose the machinery: class performance, sexual double standards, political euphemisms, the whole playacting that keeps the drawing room from turning into a courtroom. That’s why sincerity becomes a weapon, and why society punishes it as if it were aggression.
Shaw’s context matters: late-Victorian and Edwardian Britain prized decorum, coded speech, and moral posturing. His theater specialized in characters who puncture that code and pay for it. The line isn’t anti-truth; it’s a warning about power. In a world built on agreed-upon fictions, clarity is a form of sabotage, and the saboteur is most at risk when everyone knows he meant it.

Evidence: It is dangerous to be sincere unless you are also stupid. (Appendix: "Maxims for Revolutionists" (appears under the "The Perfect Gentleman" section in the 1903 text; exact page varies by edition)). This line appears in Shaw’s own text in the "Maxims for Revolutionists" appendix to the play/book "Man and Superman" (written/published 1903). A scan-backed online text of the same appendix is also available via Wikisource (see "Man and Superman/Maxims for Revolutionists"), which likewise contains the sentence verbatim. Bibliographic records for the 1903 printed first edition list publication as Westminster: Archibald Constable & Co., Ltd., 1903 (physical collation varies by copy/issue), but the quote’s exact page number depends on the specific printing/typesetting; the Project Gutenberg HTML transcription does not preserve original pagination. Supporting references: Wikisource text (scan-backed) and library catalog records (e.g., Morgan Library / WorldCat) confirm the 1903 edition/publisher details.
