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.

There is police activity at 28th St. and University Ave., at UPC, but no immediate threat exists. Please stay away from the area.

  • Sourcepresent19/25

    Final assessment

  • Hazardabsent0/25

    Final assessment

    0 of 25 passes marked Hazard present. Police activity does not name a specific 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.

  • Locationpresent25/25

    Final assessment

    25 of 25 passes marked Location present. The text gives 28th St. and University Ave., at UPC.

    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

    25 of 25 passes marked Guidance present. It says please stay away from the area.

    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

    0 of 25 passes marked Time present. There is no clock, date, or recency cue such as now or until further notice.

    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

    25 of 25 passes marked Impact present. The clause no immediate threat exists states the 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.
