The Illusion of Productivity

The illusion of productivity is the specific cognitive distortion that Sophie Leroy’s research on attention residue implies and explicitly describes: the subjective experience of competent momentum that accompanies rapid task-switching is systematically decoupled from the objective quality of the cognitive work being performed. When switching between tasks, the switching itself generates a kind of cognitive arousal—a heightened state of activation that feels like productivity. The brain is working hard. Decisions are being made. Outputs are flowing. The sensation of effort is real. What is illusory is the inference that effort equals quality. A substantial portion of that effort is overhead: the cost of disassembling one cognitive constellation and assembling another, suppressing residue from the previous task, reconstructing context for the current one. This overhead is indistinguishable, from the inside, from productive cognitive work. The builder who has switched between five projects feels that she has worked as hard as, or harder than, the builder who spent the day on one. Her
