Hurricane closure; storm damage to a residence hall displaced 387 students

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.

• Sourcepresent24/25

  Final assessment

  Near-unanimous (24 of 25): the message repeatedly names "the university" as the closing authority, identifying the sender; one lone read missed it.

  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.

• Hazardabsent6/25

  Final assessment

  Majority (19 of 25): no specific hazard is named, only classes canceled "to prepare and be safe"; a minority inferred a winter storm from context, but it is never stated.

  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

  All 25 reads agree: locations are given, including "on campus" and "the Saturday football game at FIU."

  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.

• Guidancepresent24/25

  Final assessment

  Near-unanimous (24 of 25): recipients are told what to do, since employees "are expected to report to work on Wednesday" and classes are canceled; one read wanted an explicit protective action.

  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: clear timing is given, including "starting at 11 p.m. tonight," Wednesday, and Thursday.

• Impactpresent13/25

  Final assessment

  Present by a razor-thin 13 to 12 split: it cancels classes to let the community prepare and be safe ahead of the hurricane, conveying the storm's threat to safety; the near-even dissent holds no specific harm or storm severity is stated.

  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.
