Message elements

How the first alert is built

To check this alert, Claude (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

    All 25 reads agree (1): Seattle Fire Department holds the lead role and "is investigating" the report.

    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.

    Final assessment

    All 25 reads agree (1): Threat centers on a reported "smell of natural gas."

    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.

    Final assessment

    All 25 reads agree (1): Odor sits "near several buildings in the central area of 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.

    See all 25 individual reads

  • Guidancepresent25/25

    Final assessment

    All 25 reads agree (1): Text directs people to "Follow directions from firefighters at the scene."

    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

    All 25 reads agree (1): Clock mark reads "9:35 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.

    Final assessment

    All 25 reads agree (0): No outcome or risk beyond the gas smell is spelled out.

    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.
