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 W. 23rd St. & Oak St. but no immediate threat exists. Please stay away from the area.

  • Sourcepresent25/25

    Final assessment

    Present, 25 of 25. The reads treat "There is police activity" as naming law enforcement the responding authority, the only attribution this short notice offers.

    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. "police activity" names no hazard, and the message adds "no immediate threat exists", so nothing specific is being warned about.

    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 "W. 23rd St. & Oak St." pinpoints where the activity is, a specific street corner.

    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

    Present, 25 of 25. "Please stay away from the area." is a plain protective instruction to recipients, unanimously read as guidance.

    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. The message carries no date, clock time, or recency word; the bare "There is" was not counted as timing by any read.

  • Impactabsent0/25

    Final assessment

    Absent, 0 of 25. The alert affirmatively denies harm, saying "no immediate threat exists", instead of describing any potential consequence.

    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.
