Mediating involvement happens when information flows from person A to B to C, where A and C rarely talk directly. A & C could be individuals or a group. In some cases there are multiple Bs! Think about the telephone game where everyone sits in a circle passing a message around until it comes back to the source. It's often crazy what gets back, even with the best of intentions. Imagine having a conversation back and forth between the first and last person in the circle!
