The human in the loop of a delegated agent: the theory of adjustable social autonomy

We refer to social autonomy in a collaborative relationship among agents based on delegation and help. We address the problem of adjustable autonomy. We stress in particular the role played in autonomy by: 1) the degree of “openness” of delegation; 2) the allowed initiative in (re)starting negotiation; 3) the degree and kind of control; and 4) the strength of delegation with respect to interaction. We show how the adjustability of delegation and autonomy is actually “bilateral”. Adjustment is also “bidirectional” and multidimensional. Finally, we analyze some reasons for modifying the assigned autonomy and show how the adjustment of autonomy depends: on the delegator´s side; on a “crisis of trust” and vice versa; the delegee´s adjustment of its own autonomy depends on some disagreement about the trust received from the delegator, and, in particular, either a higher or lower confidence in itself or in external circumstances. Some preliminary hints about necessary protocols for adjusting the interaction with agents are provided. This work is aimed at providing a theoretical framework, i.e., the conceptual instruments necessary for analyzing and understanding interaction with autonomous entities
