Neo-functionalism ascribes a dynamic role to interest groups in the process of integrating pluralist communities. By participating in the policymaking process, interest groups are expected to develop a stake in promoting further integration in order to acquire economic payoffs and additional benefits from maintaining and stimulating the organization through which certain demands can be articulated and goals attained. This implies that in the integration process interest groups have an instrumental role to play in the maintenance of the system; and that by virtue of their participation in the policy-making process of an integrating community they will “learn” about the rewards of such involvement and undergo attitudinal changes inclining them favorably towards the system. Thus, they acquire an interest in seeing the system's perpetuation, and the policy and decision makers acquire an interest in being responsive to interest groups' demands. What is implied overall is that actors' loyalties will shift towards those decision makers in the systems best able to reward them.
