Under disconnected leaders, decision making tends to be done in isolation, either solely by the leaders or in organizational silos that they build or foster. Sometimes disconnected leaders allow one or two people into their worlds, but usually only to act as human shields, allowing the Corner One leader to stay in a bubble. Such a shield might be a colleague, a direct report, a spouse, or anyone else who helps the leader stay disconnected from the whole, and that connection itself is usually not very healthy—mutually beneficial, they both may feel, but not healthy.
