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.
Illini-Alert Emergency. There is an incident of mob action near 306 E Green St, Champaign. An offender displayed a weapon. Avoid area.
Final assessment
Present, 25 of 25 agreeing, since the message is tagged "Illini-Alert Emergency", identifying the campus alerting system as its 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.
Final assessment
Present by 25 of 25: "an incident of mob action" is sharpened by "An offender displayed a weapon", together naming a specific armed disturbance.
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
Present at 25 of 25, since the alert gives a street address, "near 306 E Green St, Champaign", locating the mob action precisely.
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 by 25 of 25: "Avoid area" is the single protective instruction, and every read treats it as direct guidance 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
Absent, 0 of 25. The alert says an offender "displayed a weapon" but attaches no clock time, date, or recency phrase such as just occurred.
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 at 0 of 25. A displayed weapon is reported without any statement of the danger it poses or what harm could result for people nearby.
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.
