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.

Emergency Notification: Gas Leak Reported at Wilbur Powerhouse Emergency Response is investigating a reported gas leak at: Wilbur Powerhouse and currently a gas diagnostic is in progress. Immediate Action Required Action: All individuals should evacuate the area immediately. Move at least 300 feet away from the building. Do not return until an official "All Clear" is issued.

  • Sourcepresent23/25

    Final assessment

    Nearly all reads (23 of 25) find Source present: Emergency Response is named as the investigating authority on an Emergency Notification. Two dissenters call those labels too generic without a campus brand.

    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.

    See all 25 individual reads

  • Hazardpresent25/25

    Final assessment

    All 25 reads find Hazard present because the text names a gas leak, a specific threat rather than a generic incident.

    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: the leak is reported at Wilbur Powerhouse, a named building.

    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

    All 25 reads find Guidance present: everyone is ordered to evacuate immediately, move 300 feet away, and not return until an official All Clear.

    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.

  • Timepresent25/25

    Final assessment

    All 25 reads find Time present via currently, immediately, and not returning until an official All Clear is issued.

    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: a gas leak plus evacuation orders name the hazard and give guidance without stating explosion risk, injury, or danger.

    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: No stated consequence such as explosion risk, injury, or danger appears beyond the leak itself.
    2. absent: Naming a gas leak does not by itself state consequences such as explosion risk or injury.
    3. absent: Gas leak plus evacuation orders name the hazard and give guidance but never state explosion risk, injury, or other harm.
    4. absent: A gas leak is named but no consequence such as explosion risk or injury is stated.
    5. absent: No wording states explosion risk, injury, or that the leak is dangerous or life threatening.
    6. absent: No consequence is stated, such as risk of explosion, injury, or that the leak is dangerous.

    12. absent: The gas leak and distance to evacuate do not state what the leak could do or how serious it is.

    14. absent: A gas leak is named but the text does not state explosion risk, injury, or other harm.
