It's about the "boy who cried wolf" vs how incident management works.

False positives can make real issues get an insufficient response when they occur (e.g. sentinel getting eaten).

False positives can be a far more serious issue than people are willing to admit. There are plenty of loss of life incident reports that include wording like "the operator disabled the alert system due to numerous false positives" near the beginning.
