Social and political movements have a wide range of effects. The biographical consequences of social movements are one of them. They can be defined as effects on the life course of individuals who have participated in movement activities, effects that are at least in part due to involvement in those activities. Other types of effects include political and cultural outcomes. Political consequences are those effects of movement activities that alter in some way the movements' political environment. Policy outcomes, a special category of political outcomes consisting of changes in legislation or other policy measures induced by social movements, are among the most often studied. Cultural outcomes are those effects of movement activities that alter in some way the movements' cultural environment. They are perhaps the most difficult to study empirically as they are not easily identified, they depend on a wide range of other actors and events, and often they make themselves felt only in the long run. In addition, one can also imagine the existence of that which some have called spillover effects, that is, effects of movements on each other.
