Double linking is the principle that two nested circles are connected by a double link: the leader is the top-down link, representing the next-higher’s circle’s voice in the circle but being a full member (with consent rights) in both circles. The delegate (or rep) is the bottom-up link, representing the circle’s voice in the next higher circle (but, again, being a full member of both circles).
Double linking ensures flow of information and transparency in all directions. It also makes sure there is no power-over because two individuals who are members of both the higher and the lower circle have consent rights in both circles. The higher circle cannot make a decision over the lower circle because of double linking. Double linking also increases the level of information because two people filter information according to their perspective.
