How the first alert is built
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.
Dear students, I write to you with a heavy heart as we begin to learn the early details of Saturday night's Boston-Cambridge shuttle accident and we await word on the condition of 27 riders who were transported to area hospitals. Sadly, we know that one person on the shuttle has died. We ask that anyone with information about the accident please reach out to Brandeis Public Safety at 781-736-3333. We will update our community as we learn more information. The Brandeis Counseling Center can be reached 24-7 at 781-736-3730 and is available to assist students throughout the night. The Counseling Center will be open Sunday from 12 to 4 with grief counselors; students are encouraged to drop in for support. The Dean of Students Office, the Office of Graduate Student Affairs, and the Center for Spiritual Life will be open Monday-Wednesday this week. Please consider reaching out to your family and close friends to let them know that you are safe. I encourage you to check in on your friends in the coming days and to be gentle with yourself and those around you. Sincerely, Andrea Dine Interim Vice President for Student Affairs

Hazardpresent25/25
Final assessment
Unanimous: the Boston-Cambridge shuttle accident is named as the hazard.
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.

Locationabsent8/25
Final assessment
Majority found no specific address or building given, only the general 'Boston-Cambridge shuttle' route name; a notable minority credited the route reference as sufficient location context.
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.

Guidancepresent23/25
Final assessment
Strong majority found the request to reach out to Brandeis Public Safety with information and to check on friends counts as actionable guidance; a couple of reads called this purely informational.
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.

Timepresent25/25
Final assessment
Unanimous: 'Saturday night' and specific counseling hours give clear timing.

Impactpresent25/25
Final assessment
Unanimous: the message states one person on the shuttle has died and 27 riders were hospitalized.
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.
