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

    Absent on a 1 of 25 vote. No police, campus office or alert tag signs the thread; the lone dissenter seized on "not affiliated with the University of Washington", which identifies the victim, not the sender.

    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. The threat is named as "an armed robbery in the 4500 block of 19th Avenue NE. involving three men with a gun".

    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

    Present, unanimous at 25 of 25. The scene is "the 4500 block of 19th Avenue NE", with suspects tracked "westbound on 47th from 18th Avenue NE" and then on 45th.

    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

    Absent, with 0 of 25 finding guidance. The updates supply suspect descriptions and directions of travel, and even note "Area reopening", but never tell recipients to avoid, shelter or report anything.

    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.

    Present, unanimous at 25 of 25. Every entry is stamped, from "2:15 p.m." through "2:20 p.m.", "2:24 p.m." and "2:40 p.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.

  • Impactabsent1/25

    Final assessment

    Absent on a 1 of 25 vote. The text says "No one was hurt during the robbery" and states no potential harm; one read inferred danger from armed suspects still at large, which the message never asserts.

    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.
