  • Impactabsent1/25

    Final assessment

    24 of 25 reads find Impact absent. Buzzing entry and missing packages describe the crime. The Clery serious or continuous threat line is legal boilerplate, not a stated consequence.

    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.
