A constructivist approach is applied to characterizing social embeddedness.
Social embeddedness is intended as a strong type of social situatedness. I
t is defined as the extent to which modeling the behavior of an agent requi
res the inclusion of other agents as individuals rather than as an undiffer
entiated whole. Possible consequences of the presence of social embedding a
nd ways to check for it are discussed. A model of co-developing agents is e
xhibited which demonstrates the possibility of social embedding. This is an
extension of Brian Arthur's 'El Farol Bar' model, with added learning and
communication. Some indicators of social embedding are analyzed and some po
ssible causes of social embedding are discussed. It is suggested that socia
l embeddedness may be an explanation of the causal link between the social
situatedness of the agent and it employing a constructivist strategy in its
modeling.
