Individuals simultaneously choose and are affected by their web of connecti
ons. This paper explores this co-evolution of individual and network in the
context of longitudinal attitudinal and sociometric data collected from a
government agency, the Office of Information and Regulatory Affairs. Analys
is of these data suggests that networks vary in their elasticity - where th
e internal network of the agency was rigid, but the extra-organizational ne
twork quite fluid. Further, the data suggest that, consistent with theories
of socialization, individuals differ in plasticity - how they are affected
by the network - where the cross-sectional analysis of the data suggest th
at individuals were molded by the organization, but that the attitudes of i
ndividuals who left were unaffected by the change in milieu.
