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.

  • Hazardpresent25/25

    Final assessment

    All 25 reads agree that a hazard is named: Names the specific hazard "Sexual Assault".

    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 agree that a location is given: Specifies "a residential housing complex located on the south side of the Tempe campus".

    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

    A clear majority of the reads find that guidance is given: It instructs those with information to "contact the ASU Police Department", which is the only directed action given. A sizable minority disagreed, noting no protective action directed to recipients; it only asks those with information to contact police.

  • Impactpresent25/25

    Final assessment

    Present by unanimous agreement: it reports a sexual assault of a victim by a known suspect, an explicit 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.

About this analysis
Context

Background

Arizona State University operates one of the largest Clery Act timely warning archives in the country at cfo.asu.edu/clery-timely-warning, where every qualifying incident is published on a dedicated, date-stamped URL. On the evening of September 11, 2024, a sexual assault occurred in a residential housing complex on the south side of the Tempe campus. The suspect was an acquaintance who had been in the victim's room with a group; when the others departed, the reported assault occurred. ASU Police received the report on September 12, 2024 and posted the Clery timely warning the same day. The incident occurred during the first weeks of the fall semester, within the campus safety research period known as the Red Zone, when first-year students face elevated sexual assault risk. ASU's transparent, URL-per-incident archive approach contrasts with many institutions that publish only aggregate statistics or bury timely warnings in generic alert feeds, and the Tempe campus has been the subject of federal Clery Act review in prior years.
Analysis

Key Findings

ASU maintains a Clery timely warning archive with a unique URL per incident, which supports longitudinal research
The assault pattern described (acquaintance in the room with a group; others depart; assault occurs) is a common scenario identified in campus sexual assault research and bystander intervention curricula
The incident fell within the Red Zone, the first weeks of the fall semester, consistent with national data showing elevated sexual assault risk in early September
ASU has faced federal Clery Act scrutiny in prior years, making its public-facing timely warning archive both a legal obligation and a reputational investment
Outcome
Investigation ongoing at time of timely warning. Suspect was known to the victim. No public arrest reported.
