Engineers make decisions as if a bear were chasing them. Scientists are eaten by bears.
I just made that up; it needs another sentence about the role of bear detection/avoidance.
I think I'll check in with DARPA. Should probably check prior art in my copious free time first.
Bonus question: what does the ROC curve for the population of TSA screeners look like?

My original text used "early" but I decided it wasn't sufficiently erudite.
A long, long time ago in a career far, far away, TSA agents found a 5.999" inch cold chisel in my laptop back. I was 0.001" from Gitmo that day. TSA agent got a nice, free, cold chisel.
On average, for the population of screeners, the unassisted-by-technology ROC curve is a straight diagonal line at 45° that starts at the origin and extends to the upper right. After pondering that and the wiki page on ROC curves, the meaning of this can be summarized in a single word.
Bonus-bonus question: what is the mechanism of the gain for this "detector?" (Answer: the current threat level.)
I went through screening some years ago, then sat down to re-organize by stuff. What's that bright yellow thing in the bottom of my bag? I almost had it out when I realized it was a box knife. Now what? Go up to an agent and say "I have a knife"? Slip it into a trash can? Will some remote screener see it and call for a swarm? Well, since I was a good guy with a knife, I kept it.
Anyway, ROC was not good that day.

I stopped reading Zen and the Art of Motorcycle Maintenance when it caused me to question the QUALITY of my teaching. Curt...buy an SEM. We can find fun 928 things to look at.
