Message elements

How the first alert is built

To check this alert, SuperGrok Heavy 4.5 (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.

UWPD is on the scene of an active police incident on the east side of the UW Arboretum. Please avoid the area. More information to follow.

  • Sourcepresent25/25

    Final assessment

    UWPD is a named agency at the start of the message.

    Who is sending the alert and who is responding. People act faster on a message from a clearly identifiable, credible sender, such as a named department, the police, or a branded alert system, than on an anonymous notice. A branded signature counts.

  • Hazardabsent0/25

    Final assessment

    active police incident is generic; the first burst does not name a specific hazard such as a device or shots.

    What the threat actually is. A complete warning names the specific danger, such as a shooter, a fire, a tornado, or a gas leak, rather than a vague emergency, because people decide what to do based on what they are facing.

    1. absent: This pass finds no a specific threat name such as shots fired or suspicious device anywhere in the body, so the element is absent.

    11. absent: This independent pass sees no a specific threat name such as shots fired or suspicious device to quote.
    12. absent: Coding absent; the body omits a specific threat name such as shots fired or suspicious device.
    13. absent: No clause in the alert does the work of a specific threat name such as shots fired or suspicious device.

    18. absent: Without a specific threat name such as shots fired or suspicious device in the wording, the element is missing.
    19. absent: Present would need a specific threat name such as shots fired or suspicious device; that language is not used.
    20. absent: I record absent after confirming the product lacks a specific threat name such as shots fired or suspicious device.
    21. absent: The alert does not identify a specific threat name such as shots fired or suspicious device in any sentence.
    22. absent: Missing a specific threat name such as shots fired or suspicious device is the reason for the absent vote.
    23. absent: This pass will not infer a specific threat name such as shots fired or suspicious device from neighboring facts.

  • Locationpresent25/25

    Final assessment

    east side of the UW Arboretum is a named place.

    Where the threat is. Saying whether danger is in a specific building, a part of campus, or area-wide lets people judge their own proximity and choose a safe direction. Without a where, a warning is hard to act on precisely.

  • Guidancepresent25/25

    Final assessment

    Please avoid the area is a protective instruction to recipients.

    The protective action to take. A clear, specific instruction, such as shelter in place, evacuate, avoid the area, or run-hide-fight, drives faster and more correct protective behavior than describing the threat alone.

  • Timeabsent0/25

    Final assessment

    The first burst has no clock, date, now, or immediately.

    When the message applies. A timestamp, the word now or immediately, or a phrase like until further notice tells the reader whether the danger is current and how quickly to act.

  • Impactabsent0/25

    Final assessment

    No consequence language such as dangerous or life-threatening appears.

    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.
