What a claim record is How to read this page

One statement, bounded on purpose

The headline is a single claim that a named source supports. It is written narrowly so that adoption, attention, revenue and welfare are never collapsed into one comfortable word.

The three sections below the fold

What this does not establish is the boundary of the evidence. Counterevidence & uncertainty is what argues the other way. What would change the reading is the observation that would move it. A record missing any of the three is incomplete, not merely brief.

Primary routes are checkable

Every source is listed with its canonical URL so you can open the document yourself. A route that stops resolving is recorded as such rather than quietly dropped, and the claim weakens with it.

MWITA-SG-2026-017 · Evidence A · P1

In a 2025 Chinese randomized trial of 160 university students, eight weeks of team competition, points, leaderboards, feedback and rewards on top of the same watch-app platform and activity goals produced 2,114 more daily steps and 28 more daily minutes of moderate-to-vigorous activity than monitoring alone.

What this does not establish

The study does not isolate leaderboards from rewards, demonstrate post-incentive persistence or establish population-scale health benefit.

Counterevidence & uncertainty

Single-university, open-label design, retrospective trial registration and no postintervention durability assessment constrain inference.

What would change the reading

Update with prospectively registered multiarm replication, post-incentive follow-up and diverse campuses.
