  "supported_claim": "Disabling automatic notifications can reduce notification interruptions; in this field experiment, fewer interruptions mediated better perceived performance and lower irritation.",
  "unsupported_or_overstated_claims": [
    "All notifications should be off all day for everyone.",
    "The study proves an optimal focus-block duration.",
    "The effect is independent of FoMO and response expectations."
  ],
  "limitations": [
    "The study was a one-day field experiment, so it does not establish durable effects of notification blocking over longer work periods or adaptation over time.",
    "Performance and irritation outcomes were self-reported, and the direct intervention effect on performance was not significant; the reported performance pathway was indirect through fewer interruptions.",
    "Work roles differ in response-time obligations, telepressure, fear of missing out and safety or escalation requirements, so an always-off notification rule is not supported.",
    "The study tests communication-application notification interruptions, not every form of digital distraction or every focus-window design."
