Abstract
Background: It is widely assumed that more group members produce more output. We test the competing hypothesis that group project effort is conserved, with total work fixed regardless of headcount.
Methods: We observed 240 student groups (size N = 1 to 9). Total output was measured in 'one person's sleepless night' (1 SN). Per-capita contribution was inferred from commit logs, guilt, and who 'looked for materials.'
Results: Total work done equaled 1.0 SN across all group sizes (R² = 0.98). Per-capita contribution fell as 1/N. We detected a dark-effort component — a member who 'researched options' but produced nothing observable — present in 100% of groups.
Conclusion: Group project effort is conserved. Adding members redistributes credit, not labor. We propose the SN as a base SI-adjacent unit, pending the lone author finishing the paperwork tonight.
