  "title": "Run a bounded mobile-internet block when constant phone connectivity is the suspected problem",
  "summary": "Sometimes the cleaner experiment is to remove the pipe, not negotiate with every tap.",
  "kind": "template",
  "body": "The 2025 randomized trial blocked mobile internet on smartphones for two weeks while preserving calls, texts and desktop internet. Participants improved on sustained attention and several well-being outcomes. Use that design as a bounded experiment when feasible: remove mobile internet access, preserve essential communication and observe what changes.",
  "limits": [
    "The RCT tested a specific two-week intervention; some jobs, accessibility needs and safety contexts require mobile data."

    "Your smartphone feels like the main source of fragmented attention, but deleting individual apps has not clarified the effect."

    "The RCT tested a specific two-week intervention; some jobs, accessibility needs and safety contexts require mobile data."
  ],
  "example": "For one or two weeks, use the phone for calls, SMS, camera and offline tools while doing intentional web access on a computer.",
  "check": "The experiment changes constant mobile internet availability rather than merely asking for more self-control.",
