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.

    Final assessment

    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

    Present, unanimous at 25 of 25. "Tornado warning" is stated in the opening clause as the specific severe weather threat.

    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.

  • Locationabsent0/25

    Final assessment

    Absent, 0 of 25 voted present. This spaced version still names no county, campus area or building; only the instruction to be indoors hints at any geography.

    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. Recipients are told to "shelter indoors", to "remain until warning expires" or all clear, and to "check TV/radio for updates".

    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

    Present, 25 of 25 with no dissent. The text states the warning "expires at 9:30 PM", an explicit clock time ending the shelter window.

  • Impactabsent0/25

    Final assessment

    Absent, 0 of 25 voted present. No damaging winds, destruction or threat to life is described; the alert stops at the hazard label and the action.

    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.
