Weather-related delayed start MU Alert notice

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 speaks for "the MU campus and UM System operations" and refers readers to "the MU Alert weather page", marking institutional authorship.

  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.

• Hazardpresent25/25

  Final assessment

  Present, 25 of 25. "continuing wintry conditions" names the weather hazard that keeps the campus closed, which no read disputed.

  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. "the MU campus and UM System", with MU Health Care hospitals and the Veterinary Health Center, identify the affected locations.

  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.

• Guidancepresent22/25

  Final assessment

  Present, 22 of 25. "Employees should check with their supervisors" and the referral to the MU Alert weather page are instructions to recipients; three reads called them administrative rather than protective.

• Impactpresent13/25

  Final assessment

  Present, but only 13 of 25. "wintry conditions limiting travel" states an effect of the hazard; the twelve dissenting reads judged limited travel an operational fact rather than harm 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.
