Weather-related campus closure MU Alert notice — closure

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.

  Final assessment

  Present, 25 of 25. The message opens "MU Alert: MU/UM will be closed", tagging the university alert system as the sender with no dissent.

  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.

• Hazardabsent0/25

  Final assessment

  Absent, 0 of 25. Every read agreed that "due to weather" supplies only a generic cause and never names a storm, ice or other specific threat.

  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

  Present, 25 of 25. "MU/UM" plus the named vital services, "UMHC, vet health center, campus dining", identify the Columbia campus as the affected place.

  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

  Absent, 0 of 25. Unanimous that "Classes canceled" and unchanged service hours are operational notice; recipients are asked to take no 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.

• Impactabsent0/25

  Final assessment

  Absent, 0 of 25. No read found any statement of harm or severity; the weather consequences described are administrative closures, not danger to people.

  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.
