  "title": "Preserve calls and texts when you want to test mobile internet rather than social isolation",
  "summary": "If the question is constant internet access, keep the parts of the phone that are not the question.",
  "kind": "question",
  "body": "The 2025 RCT isolated mobile internet while leaving texts and phone calls available. Borrow that logic when the research question is online access: keep essential direct communication and remove the always-available feed/browser layer. This makes the intervention less disruptive and the mechanism easier to interpret.",
  "limits": [
    "Modern messaging often depends on data rather than SMS; define exceptions from actual communication needs."

    "A 'phone detox' removes every communication channel at once, making the result hard to interpret."

  "avoid_when": [
    "Modern messaging often depends on data rather than SMS; define exceptions from actual communication needs."
  ],
  "example": "Keep family calls and two-factor SMS while removing browser/social-media mobile data during the trial.",
  "check": "The trial targets the suspected mechanism without unnecessarily cutting essential human contact.",
  "question": "Is the problem direct communication or constant internet access? · Which phone functions must remain available for safety and relationships? · Can the online functions move to a deliberate device or place?",
