{{Main|Chatham House Rule}}

Chatham House is the origin of the non-attribution rule known as the Chatham House Rule, which provides that a participant in a meeting may discuss the content of this meeting in the outside world, but may not discuss who attended nor identify what a specific individual said. The Chatham House Rule evolved to facilitate frank and honest discussion on controversial or unpopular issues by speakers who may not have otherwise had the appropriate forum to speak freely. Most meetings at Chatham House are held [[Journalism sourcing#Using confidential information|on the record]] rather than under the Chatham House Rule.<ref>Richard Horton, "Offline: The Chatham House Rule, over-ruled."
