"A second way in which milieu control is affects group members is linked to groups' conscious efforts in that regard. That is, the groups maintain milieu control especially by way of labeling recalcitrant members as 'subjective' or 'objective agent.' The former term is used for those who are thought to have harmed the organization by their mistakes or failures in groups' operations."
