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.
IU Indy emergency: A dangerous situation is occurring near 402 Blackford Street, Science Building. Avoid the area. Call 911 with information.
Final assessment
Unanimous: 'IU Indy emergency' is a branded sender signature naming the source.
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
Absent by unanimous agreement: 'a dangerous situation' is generic and names no specific threat such as a shooter or fire.
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 'near 402 Blackford Street, Science Building' gives a precise location.
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
Present unanimously: 'Avoid the area. Call 911 with information.' are direct protective instructions to recipients.
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
Present by majority: 18 of 25 read 'is occurring' as conveying an ongoing, happening-now event, while 7 dissenters wanted an explicit clock time or the word 'now'.
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
Present unanimously: the word 'dangerous' explicitly conveys the severity or potential harm of the situation.
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.
