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.

  • Hazardpresent25/25

    Final assessment

    All 25 reads find Hazard present. The text names a specific threat such as shots, robbery, or inclement weather.

    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.

  • Locationpresent25/25

    Final assessment

    All 25 reads find Location present. A street, block, or campus location is given.

    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

    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

    All 25 reads find Time absent. No clock time, date, or recency cue such as now or immediately appears.

    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

    All 25 reads find Impact absent. Naming the crime or closing operations does not state a consequence for people or property.

    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: The text does not state any consequence or severity, such as injuries or that the situation is dangerous.
    2. absent: The text does not state any consequence or severity beyond naming gunshots.

    10. absent: Naming gunshots is the hazard only, with no consequence or severity such as dangerous or injury.
    11. absent: Nothing states consequences or severity such as injuries or danger, and naming gunshots alone does not satisfy Impact.

    13. absent: The text does not state consequences or severity beyond naming gunshots and telling people to be cautious.
    14. absent: Gunshots names the hazard, but no injury, danger, or other consequence is stated.
