Telephone Game

Telephone Game	Communications Protocol
Whisper in a noisy environment.	Boost the signal-to-noise ratio: speak louder, diminish the source of noise, use simpler encoding system (e.g., Morse code vs. voice, binary vs. analogue).
Use unfamiliar language.	Use terms that are appropriate to your audience.
Say the sentence only once.	Repeat the message as often as necessary.
Allow no questions from the receiver.	Allow as many questions as needed.
Don't allow the receiver to repeat the message to the person transmitting the message.	Test the receiver to make sure the transmission was received correctly.
Address only one person.	Address a group of people who can cross-check, confirm, or correct what they heard.
Demand immediate re-transmission.	Do not allow the receiver to re-transmit the message until you are sure of the integrity of the message. Authorized receivers (bishops, priests, deacons) act as guardians of the transmission. Remove (excommunicate) transmitters that habitually distort the message--take them off-line.
Foster conditions that favor random mutation.	Foster conditions that conserve/preserve the message.
