Message elements

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.

There is potential for severe weather today. The start of the game may be delayed or play suspended if there is lightning within 10 miles. Instructions will be shared over PA, video screens & Twitter. Shelter locations include vehicles, Pioneer HS & U-M facilities. Stay tuned.

    Final assessment

    All 25 reads agree the element is absent: no sender, agency, or branded signature identifies who issued the stadium message.

    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

    All 25 reads agree the element is present: it names lightning detected within 10 miles, a specific 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.

    Final assessment

    All 25 reads agree the element is present: it references the stadium, the field and seating bowl, and shelter areas.

    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.

  • Guidancepresent25/25

    Final assessment

    All 25 reads agree the element is present: it instructs spectators to clear the field and seating bowl and seek shelter under the concourse.

    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.

  • Impactpresent25/25

    Final assessment

    Present unanimously (25 of 25): warns that lightning has been detected within 10 miles and directs seeking shelter, conveying the danger lightning poses to spectators.

    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.

About this analysis
Context

Background

Michigan Stadium, the largest stadium in the United States, cannot shelter its roughly 110,000-capacity crowd, so its severe-weather plan relies on moving fans to the concourse and to nearby buildings such as the Indoor Track Building and Crisler Center. On September 10, 2022, isolated storms and lightning near the stadium delayed the Michigan-Hawaii opener, with Michigan announcing the kickoff delay at about 7:24 p.m. EDT ET and ultimately resetting it to roughly 9 p.m. ET. The Wolverines won the weather-delayed game 56-10. The episode echoed earlier lightning disruptions at the venue, including the first-ever weather delay in 2006 and the called 2011 Western Michigan game that forced the evacuation of more than 110,000 fans.
Analysis

Key Findings

Michigan clears the seating bowl when lightning is detected within 10 miles, a stricter trigger than the NCAA 8-mile minimum
With no shelter for its full crowd, Michigan Stadium routes fans to the concourse and to the Indoor Track Building and Crisler Center
The delay pushed a planned afternoon/early-evening kickoff to roughly 9 p.m. ET, gates reopening near 8:30 p.m. EDT ET
The first two messages are verbatim from the official @UMichAthletics X account; only the final all-clear remains reconstructed
Outcome
Gates reopened around 8:30 p.m. EDT and the game kicked off about 9 p.m. EDT; Michigan defeated Hawaii 56-10.
