Final assessment
Unanimous: the title "Sexual Assault" names the hazard, describing a male who groped a victim.
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
All 25 reads find a specific location: "the 1000 block of Vaughn Street".
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
Unanimous: recipients are advised to "Walk with a trusted friend" and "Consider late-night transportation options".
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.

Final assessment
Absent by strong consensus (23 of 25): the groping is described but no injury or explicit severity is stated. Two reads counted "groped her" after pulling her toward him as stated harm.
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.
