Message elements

How the first alert is built

To check this alert, Claude Opus 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.

There is police activity at Martin Luther King Blvd. & Vermont at UPC but no immediate threat exists. Please stay away from the area.

  • Sourcepresent25/25

    Final assessment

    Present, 25 of 25. The notice attributes the situation to "police activity", naming law enforcement as the agency on scene.

    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

    Absent, 0 of 25. No hazard type is specified behind the police presence, and the alert states "no immediate threat exists".

    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

    Present, 25 of 25. The intersection "Martin Luther King Blvd. & Vermont at UPC" locates the activity precisely.

    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

    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

    Absent, 0 of 25. Neither a clock time, a date, nor a recency word such as now appears in the message.

    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

    Absent, 0 of 25. The message states the absence of danger, "no immediate threat exists", so no severity or consequence reaches the reader.

    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.

    1. absent: The absence of threat is stated, so no consequence is conveyed.
    2. absent: The text explicitly says no immediate threat exists, conveying no severity.
