Alert Sequence
2 messages in sequence · 1 verified verbatim
Confirmed wording is transcribed character-for-character from a primary source. Use Verify this quote under each message to open that source in a new tab and compare the text yourself.
Some messages in this sequence are documented (their existence, timing, and channel are sourced) but their exact wording is not preserved in the public record. Those entries appear as placeholders; only confirmed text is displayed.
This message is documented at this point in the sequence, but its exact wording is not preserved in the public record. The public edition displays only confirmed alert text.
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.
Earlier today, members of the Lehigh University community received a disturbing email including a racially targeted threat to campus. LUPD, in coordination with the FBI, has determined the threat is not credible and that there is no ongoing risk to our community. Multiple campuses across the country were subject to similar coordinated threats today, which have been determined to be hoaxes. Out of an abundance of caution, LUPD will be increasing its presence across campus. We recognize that this message may leave some feeling unsettled. Lehigh Counseling & Psychological Services is available to students for in-person support, and Telus Health offers 24/7 online counseling with multilingual options so students can speak with someone in their native language if desired. Faculty and staff can also seek confidential support through the Lehigh Employee Assistance Plan (EAP). Resources are available for the campus community (https://www2.lehigh.edu/news/support-resources). As always, we encourage the campus community to be vigilant and aware of your surroundings. Report any suspicious persons or behavior to LUPD at (610) 758-4200. Jason Schiffer Associate Vice President of Campus Safety & Chief of Police Lehigh University Police Department

Final assessment
Unanimous agreement the message is signed by Jason Schiffer, Chief of Police, and names the Lehigh University Police Department (LUPD).
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
Unanimous agreement the 'racially targeted threat' via email names the 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.

Locationabsent8/25
Final assessment
Most reads found no specific campus location, only generic references to 'campus' and 'community'; a minority credited 'across campus' as a location, but the majority correctly finds nothing site-specific.
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
Unanimous agreement the message instructs recipients to be vigilant and report suspicious persons or behavior to LUPD.
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.

Impactabsent0/25
Final assessment
Unanimous agreement the statement of 'no ongoing risk to our community' negates rather than conveys 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.
