 More specifically, habitual action is a necessary feature of individual and collective—including institutional—life; and each single action performed on the basis of a habit, contributes in turn, and often unintentionally, to the maintenance and reinforcement of that habit. So the fact that institutional actors necessarily act in large part on the basis of habit means that many of their actions unintentionally contribute to the reproduction of the institution. However, this is consistent with a teleological account of social institutions—since, as noted above, there are outcomes other than institutional reproduction, and many of these are outcomes that are clearly aimed at. Moreover, it is consistent even with a teleological explanation of the reproduction of social institutions, since the establishment and periodic justificatory review of habits are themselves susceptible to teleological explanation.
