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.

8:30 a.m.: Seattle firefighters are responding to a report of a possible gas leak at the UW’s Electrical & Computer Engineering building. The building is being evacuated. Avoid the area.

  • Sourcepresent25/25

    Final assessment

    25 of 25 passes found Source present. Seattle firefighters are a named agency, and the text names UW.

    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.

  • Impactabsent0/25

    Final assessment

    0 of 25 passes found Impact present and 25 found it absent. Naming a gas leak and an evacuation does not state harm or severity.

    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.

    12. absent: The notice does not say the leak may injure people, explode, or is dangerous.
    13. absent: As printed, no words state that the leak could injure anyone or how serious it is.
