Social Facilitation

People and animals perform tasks with more effort and speed when in the presence of others, even passive observers — a phenomenon Owain Service cites as the psychological engine behind fitness apps like Strava, Peloton, and Zwift, whose real innovation over prior fitness trackers was making a private workout socially visible.

Founding study (Norman Triplett, 1898). An American psychologist and avid cyclist, Triplett noticed competitive cyclists rode faster racing against each other than racing the clock alone. He tested the effect directly: children reeling in a fishing line worked faster when another child was present and waiting their turn than when alone (see Triplett Fishing-Reel Social-Facilitation Study) — one of the first experiments in social psychology.

Generalizes across contexts and species. Service cites the effect extending to mental performance (faster learning, more generated arguments) and to animals — rats run a maze faster when another rat watches through a window.

A modern, unintended consequence: gaming the visibility itself. In 2024, Singapore-based "Strava jockeys" began charging roughly 50 pence per kilometre to log into a paying client's Strava account and run on their behalf, inflating the client's visible fitness feed without them exercising at all (see Strava Jockeys Singapore Case) — evidence the desire to look good to observers can be strong enough to fully decouple from the underlying behaviour it's meant to signal.
