Because network interaction also requires the expenditure of effort, I argue that the predictions of loss aversion apply not only to individual decision making on economic matters but also to interpersonal decision making on social matters. Consider, for example, a person facing the uncertainty of organizational change. To mobilize social resources such as non-redundant information that could help in responding to uncertainty, the person must first identify the set of colleagues who are most likely to possess such information. Then, having identified those individuals, the person may have to schedule multiple meetings or calls, synthesize and reconcile the information provided, and follow up on leads for additional information. Similarly, the exchange of expressive resources requires effort because it entails psychological costs—for example, having to deal with the distress of others who are sources of information or influence but who are themselves affected by the organizational change (Fiore, Becker, and Coppel 1983; Kessler and McLeod 1984). Because people facing potential loss are inclined to expend greater effort than are people facing potential gain, the former are more apt to interact with more network contacts than are the latter. Thus, I expect: Hypothesis 1: People will choose to interact with more intraorganizational network contacts in situations of loss than in situations of gain.
