Wit & Attitude Quote by George Bernard Shaw

"It is dangerous to be sincere unless you are also stupid"

About this Quote

Sincerity gets sold as moral currency, but Shaw treats it like live ammunition. The line is funny because it flips a virtue into a liability: honesty is not inherently noble, its impact depends on the intelligence of the person wielding it and the social room it’s detonated in. Shaw, a dramatist who made a career out of polite society’s hypocrisies, understands that “being sincere” isn’t just expressing a feeling; it’s a claim on reality. You’re asking others to accept your version of the world without the cushioning lies that keep institutions, marriages, and reputations intact.

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.

This line appears in Shaw’s own text in the "Maxims for Revolutionists" appendix to the play/book "Man and Superman" (written/published 1903).
