The expression conspiracy of silence, or culture of silence, relates to a condition or matter which is known to exist, but by tacit communal unspoken consensus is not talked about or acknowledged. Commonly such matters are considered culturally shameful. Taboo subjects may be indirectly discussed via the use of politically correct code words, or euphemisms.
Examples of conspiracies of silence 
The following are examples which at various times have been the subject of a culture (or conspiracy) of silence:
- Acknowledgement of war crimes
- Breaches of human rights, such as vanishing persons and torture
- Social conditions - gang crime, drugs or other unlawful or disparaged activity. Omertà, the Cosa Nostra (Mafia) cultural code of Sicily, is a significant example of an entire culture built upon silence. Stop Snitchin' is a recent example.
- Personal problems - for example the increasing alcoholism of a significant individual in some context may become the subject of a culture of silence, whereby attention is averted by the relevant group.
- Conditions considered shameful by the culture at large - for example erectile dysfunction and yeast infections
- Child abuse in the Church or in social services accommodation.
- Blue Code of Silence - When police officers refuse to speak out against the crimes of fellow law enforcement.
- Institutional Racism, Institutional Sexism
- Persecution of Christians by national socialists and communists in such countries as the Soviet Union, Mexico, Germany and Spain in the 1930s.
- Avoidance of recognition of some problem in order to officially bury (hide) a possible problem and thus avoid accusations, investigations or liability.
- Between 1972 and 1994, members of the Charlestown community in Massachusetts were unwilling to share information that would facilitate homicide investigations because of their reliance on vigilante justice, fear of retaliation by criminals, and anti-police sentiment according to the Dept. of Justice.
On 22 November 2006, Italian writer Antonio Socci claimed in his Il Quarto Segreto di Fatima ("The Fourth Secret of Fatima") that the Holy See has, in spite of its statements to the contrary, not released the Third Secret of Fatima.
Effects of a conspiracy of silence 
A conspiracy of silence in some field, has effects at many levels:
- Those who are directly suffering, or causing others to suffer, perpetuate their cycle of harm and suffering
- Those who have suffered have their suffering extended by having their condition ignored or minimized, and are not considered seriously or redressed appropriately
- Lessons that might be learned for future are not learned
