Many wrongs principle
From OpenwaterpediaMany-wrongs principle is a theory first proposed in 1964 that has implications for open water swimming and the swim leg of triathlons. The principle predicts that swimmer cohesion can cause packs to navigate more accurately than single athletes making decisions independently and alone. Group navigational accuracy is generally increased with group size and when individual directional uncertainty is high.
The many wrongs principle is often seen in open water swims and triathlons since few swimmers know the exact, optimal course.
