Wait what? You want false positives. You definitely don't want false negatives.

Absolutely, 100%, no. This is terribly wrong. I work for a company that manufactures smoke detectors, and false positives are almost as dangerous as false negatives. False positives encourage people to disregard the alarm as "just a false alarm", and ignore it, which can, and has, led to people die needlessly.
Also, if one of our products woke people up in the middle of the night because of a false alarm and they were unable to silence it, I would join them in calling it crap.
