The slower is faster (SIF) effect occurs when a system performs worse as its
components try to do better. Thus, a moderate individual efficiency actually
leads to a better systemic performance. The SIF effect takes place in a variety
of phenomena. We review studies and examples of the SIF effect in pedestrian
dynamics, vehicle traffic, traffic light control, logistics, public transport,
social dynamics, ecological systems, and adaptation. Drawing on these examples,
we generalize common features of the SIF effect and suggest possible future
lines of research
