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.
The MIT Police are working in conjunction with other local police agencies regarding a woman who reported being sexually assaulted at the Sigma Chi fraternity at 532 Beacon Street, Boston, MA between the hours of 1:00 AM and 2:00 AM on October 15, 2017. There is no suspect or suspect description at this time. The MIT Police Department was notified today, October 20, 2017, of a sexual assault that took place in the early morning hours of Sunday, October 15, 2017. The victim/survivor states she was using the bathroom in the basement of the fraternity house between 1:00 AM and 2:00 AM. As she used the stall an unknown male suspect was using the urinal in the same bathroom. After she left the bathroom stall the suspect approached and sexually assaulted her. She tried to leave, but noticed the door was locked. She unlocked the door and immediately left with her friends, who were outside the bathroom door. The incident was reported to another police agency before being reported to the MIT Police. The incident is being actively investigated by MIT Police at least one other agency.

Guidancepresent25/25

Impactpresent25/25
Final assessment
Present: Impact coded in MIT Police crime alert.
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.
