Temporal Rebound

Temporal rebound names the systematic phenomenon by which technologies that save time in the production of a given output fail to produce leisure. Instead, they produce expansion of the field of possible outputs, such that the total time spent on the relevant activity remains constant or increases. The washing machine did not produce leisure; it produced higher standards of cleanliness and more frequent laundering. The car did not produce free time; it produced longer commute distances and suburban sprawl. The email did not reduce time spent on correspondence; it multiplied the number of correspondences. The pattern is not a failure of the technologies but a structural consequence of the institutional context in which they are deployed — the context of dynamic stabilization, in which every efficiency gain must be converted into additional output to maintain the system's stability.
