« Back to Glossary IndexChatham House Rules are a framework governing the confidentiality of discussions held in meetings, workshops, or forums—originally established by the Royal Institute of International Affairs (Chatham House) in London—to encourage open and honest exchange of views. Under these rules, participants are free to use the information received, but the identity or affiliation of speakers, or that of any other participant, must not be revealed.
Unlike formal confidentiality agreements, which are legally binding contracts, Chatham House Rules rely on professional trust and mutual respect among participants. Their purpose is to create an environment where individuals can express opinions, share insights, and debate sensitive topics without concern that their statements will be publicly attributed or misrepresented. The rules are frequently invoked in policy discussions, international negotiations, corporate strategy sessions, and risk communication forums where candor and collaboration are essential.
Context
For example, a multinational roundtable on cybersecurity might be conducted under the Chatham House Rules to allow government officials, industry leaders, and researchers to discuss emerging threats and vulnerabilities without attribution. Participants may report on general findings or insights but cannot disclose who made specific statements.
At Risk Sciences International (RSI), the Chatham House Rules are often applied in stakeholder consultations and expert workshops. They support transparent yet non-attributable dialogue on complex risk issues, helping participants share perspectives freely while preserving confidentiality and fostering collective understanding.
