How the first alert is built
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.
7:09 p.m.: The tree has been cleared, and the road has reopened. 5:03 p.m.: No one was injured by the downed tree. Check bus routes for transit updates. 4:56 p.m.: Downed tree blocking traffic on Stevens Way at Rainier Vista NE. Use alternate routes. Crews are responding to remove the tree, but the process is expected to take a while.

Final assessment
Absent, 0 of 25 voted present. The message is only a run of time stamped updates about the tree and the road; no university, department or alert system ever identifies itself as the sender.
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. The hazard is named directly as a "Downed tree blocking traffic", with crews responding to remove it.
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 spot is fixed at "Stevens Way at Rainier Vista NE", a named campus intersection.
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
Present, 25 of 25. Two instructions are given, "Use alternate routes" and "Check bus routes for transit updates", both actionable for recipients.
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
Present, 25 of 25. The sequence is stamped from "4:56 p.m." through "5:03 p.m." to "7:09 p.m.", when the road reopened.
When the message applies. A timestamp, the word now or immediately, or a phrase like until further notice tells the reader whether the danger is current and how quickly to act.

Impactabsent5/25
Final assessment
Absent, 5 of 25. The alert reports an outcome, "No one was injured by the downed tree", rather than any potential consequence; the few dissenters counted the injury statement and the expected delay as impact.
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.
