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.

Weather Update – Columbia campus closed Monday, Sept. 11; reopening at 10 a.m. Tuesday, Sept. 12, 2017

  • Sourceabsent0/25

    Final assessment

    Majority 25/25 absent. no branded signature appears in the text itself.

    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
    1. absent: no branded signature appears in the text itself.
    2. absent: source is absent without a sender tag in the message body in the message.

  • Hazardabsent0/25

    Final assessment

    Majority 25/25 absent. no specific weather hazard is named in the text.

    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.

    1. absent: no specific weather hazard is named in the text.
    2. absent: hazard is absent without naming a storm or threat type in the message.

  • Locationpresent25/25

    Final assessment

    Majority 25/25 present. location is Columbia campus.

    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.

  • Guidanceabsent0/25

    Final assessment

    Majority 25/25 absent. campus closed is a status not a protective instruction to act.

    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.

    Final assessment

    Majority 25/25 present. time is present via Monday Sept. 11 and Tuesday Sept. 12 10 a.m..

    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.

  • Impactpresent25/25

    Final assessment

    Majority 25/25 present. impact is Columbia campus closed.

    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.
