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.

    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.

  • Hazardpresent25/25

    Final assessment

    Law Enforcement Activity names a specific situation. Majority 25/25.

    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.

    See all 25 individual reads
    1. present: Hazard is law enforcement activity, a specific named situation (UO 12th AVOID, pass 1).
    2. present: LAW ENFORCEMENT ACTIVITY names the threat class (UO 12th AVOID, pass 2).

  • Locationpresent25/25

    Final assessment

    East 12th Ave and Patterson is a named intersection. Majority 25/25.

    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.

    See all 25 individual reads
    1. present: Location is East 12th Ave and 12th/Patterson, a named street address (UO 12th AVOID, pass 1).
    2. present: 2345 PATTERSON is a specific place (UO 12th AVOID, pass 2).

  • Guidancepresent25/25

    Final assessment

    AVOID is a protective instruction. Majority 25/25.

    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.

    See all 25 individual reads
    1. present: Guidance is AVOID, a protective instruction to stay away (UO 12th AVOID, pass 1).

  • Timepresent25/25

    Final assessment

    12/8/25 12:52 PM is a date and clock. Majority 25/25.

    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.

    See all 25 individual reads
    1. present: 12/8/25 12:52 PM is an explicit date and clock time. (UO 12th AVOID, pass 1).
    2. present: T is present via 12/8/25 and 12:52 PM. (UO 12th AVOID, pass 2).

  • Impactabsent0/25

    Final assessment

    No explicit consequence in the first-burst AVOID. Majority 0/25.

    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.

    2. absent: Law enforcement activity names the situation, not a harm clause (UO 12th AVOID, pass 2).
