How the first alert is built

To check this alert, Claude (an AI) read it in full 25 separate times, independently. Each read decided whether the message answers each of the six questions and gave a short reason. A final reviewer then weighed all 25 and wrote the plain-English verdict you see when you open a row. The score (for example 22/25) is how many reads agreed; the 25 individual reads are tucked underneath if you want to check them.

  • Impactabsent5/25

    Final assessment

    Majority absent (20 of 25): naming burglaries and package thefts without separate severity language fails impact. Minority treat Clery serious or continuous threat boilerplate as impact.

    What the hazard could do to the people in its path. Beyond naming the threat, a complete warning conveys its potential consequences or severity, such as that a tornado can level buildings or that a leak could be explosive, so recipients grasp how much danger they are in. Research on warning message content finds that a concrete impact statement helps people personalize their risk and act sooner.

    See all 25 individual reads
    1. absent: Burglaries and package thefts are named without separate severity or harm wording.
    2. absent: No line states injuries, danger level, or what the crimes could do to people.
    3. absent: Impact is absent beyond naming the crime types themselves.
    4. present: Clery disclaimer says serious or continuous threat to the community, which is severity language.
    5. absent: Package removal is described factually without consequence phrasing such as dangerous.
    6. absent: The text does not say the offender is armed or that residents face personal injury risk.
    7. absent: Impact element fails under a strict reading that hazard names alone do not count.
    8. present: Serious or continuous threat in the Clery notice conveys community-level impact.
    9. absent: Piggybacking entry and package taking are events, not stated consequences or severity.
    10. absent: No injuries, no property loss amount, and no life-safety severity phrase appear.
    11. absent: Harm reduction tips imply risk context but do not state impact severity.
    12. absent: Naming burglaries and package thefts does not by itself satisfy impact.
    13. present: The disclaimer frames the crimes as a serious or continuous community threat.
    14. absent: Impact is not conveyed with words like dangerous, life-threatening, or may cause harm.
    15. absent: The body reports what happened without saying how severe the outcomes were.
    16. absent: Removed several packages describes sequence, not impact severity.
    17. absent: Strict rubric: hazard labels without consequence language yield I absent.
    18. present: Serious or continuous threat language can be read as explicit community impact.
    19. absent: No secondary effects such as injuries treated or trauma severity are described.
    20. absent: The alert stops short of stating what the hazard could do beyond naming it.
    21. absent: Consequence language for people is missing outside crime type names.
    22. absent: Impact absent: no severity adjective and no harm-to-people clause in the narrative.
    23. present: Clery serious or continuous threat clause states why the community faces impact.
    24. absent: Burglaries and package thefts names alone do not equal impact under the rubric.
    25. absent: No explicit statement of potential injury, danger, or property damage severity.
