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.

  • Hazardabsent5/25

    Final assessment

    H is present on 5/25 votes and absent on 20/25. Generic wording such as hazard and emergency does not name a specific threat type, so H is coded 0.

    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

    L is present on 25/25 votes. The alert names Temple Hoyne Buell and the street address 611 Lorado Taft Dr.

    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.

  • Impactabsent2/25

    Final assessment

    I is present on 2/25 votes and absent on 23/25. The text has no harm or severity language, and evacuation instructions alone do not establish 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: Harm or severity is not stated or clearly implied, and naming a hazard alone does not count as impact.
    2. absent: There is no stated consequence or severity beyond the hazard label itself.
    3. absent: The text does not state injuries, deaths, damage, or any other harm or severity.
    4. present: Emergency branding plus mandatory evacuation implies high local severity for people in or near the building.

    10. absent: No consequence wording. Evacuate/avoid is guidance, not impact.
    11. absent: No harm, injuries, damage, or other consequences are described.
    12. absent: No explicit at-risk population is named and no harm is described.
    13. absent: No harm, damage, or other consequence of the event is described.
