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.
Ann Arbor: 3:53am Shooting at William/Maynard. Suspect is 20s black male wearing white shirt, black pants. Avoid area. Updates: http://dpss.umich.edu https://dpss.umich.edu
Final assessment
Near unanimous agreement among the reads that a sender is identified: References "dpss.umich.edu", a named authority and sender domain. A few dissenters read it the other way, noting no branded signature appears; "dpss.umich.edu" is a URL but the text names no sender or agency directly.
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 that a hazard is named: Names the specific hazard "Shooting".
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 that a location is given: Specifies the location "William/Maynard".
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.
Final assessment
All 25 reads agree that guidance is given: Instructs recipients to "Avoid 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.
Final assessment
All 25 reads agree that no timing is conveyed: No clock time, date, or recency cue appears in the text.
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
Absent by 14-11 majority; the shooting alert names the hazard with a suspect description and to avoid the area but states no injury or explicit consequence, with substantial dissent reading gunfire as implied danger.
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.
