LAG
Metaphorically, trailing behind. In development, some variableS may change faster than others and if they are dependent on each other these temporal differences, called Lag, can cause structural stress within a system. E.g., in modern society, institutional developments tend to lag behind changes in technology causing many social problems from alienations to social inequalities and conflicts. In cybernetics, lag refers to the time for information to pass through one complete feedback loop. Lag makes regulation difficult. E.g., if the time for a gunner to obtain information about his target plus the time for his projectile to reach its destination is large, a hit is considerably more difficult than if that lag is small. A regulator's lead may compensate for the lag in a feedback loop. (Krippendorff)
