A conspiracy of silence, or culture of silence, describes the behavior of a group of people that by unspoken consensus does not mention, discuss, or acknowledge a given subject. The practice may be motivated by positive interest in group solidarity or by negative impulses such as fear of political repercussion or social ostracism. Unlike a taboo subject or the use of euphemisms, a conspiracy of silence is limited to specific social and political contexts rather than to an entire culture.
Some instances of such a practice are sufficiently well-known or enduring to become known by their own specific terms, including the code of silence, the refusal of law enforcement officers to speak out against crimes committed by fellow officers, and omertà, the cultural code of organized crime in Sicily.
Compare the Streisand effect, where deliberate efforts to suppress a particular topic or information result instead in increased awareness of the subject.
Examples of the use of the term vary widely and include:
The sinister fact about literary censorship in England is that it is largely voluntary. Unpopular ideas can be silenced, and inconvenient facts kept dark, without the need for any official ban. Anyone who has lived long in a foreign country will know of instances of sensational items of news—things which on their own merits would get the big headlines—being kept right out of the British press, not because the Government intervened but because of a general tacit agreement that "it wouldn't do" to mention that particular fact. ... At this moment what is demanded by the prevailing orthodoxy is an uncritical admiration of Soviet Russia. Everyone knows this, nearly everyone acts on it. Any serious criticism of the Soviet regime, any disclosure of facts which the Soviet Government would prefer to keep hidden, is next door to unprintable. [7]
