Advisory: Potential traffic, smoke impacts from Lake Union marina fire

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. UW posts the advisory in its own voice and attributes the fire status to "the Seattle Fire Department".

  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 concrete, a fire near the Ship Canal Bridge that "destroyed about 30 boats", producing smoke and street closures.

  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. It names Northlake Way "between 6th Avenue and 7th Avenue" plus the Publications Services Building, Northlake Building, Mercer Court Apartments and the Environmental and Occupational Health Sciences department.

  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 explicit instructions are given, "Please use alternate routes" for the closure and "keep windows and doors closed as much as possible" for smoke.

  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, 25 of 25. Consequences are quantified and localized: about 30 boats destroyed, blocked access to four UW buildings, and smoke "minorly affecting air quality" in west campus.

  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.
