So, what's the rate of false positives, given that only 1 in 1000 is a true positive?


From the source: "CCE agents identified 24 times more mock passengers (66%; 60% at Month 1 and 72% at Month 6) than suspicious signs agents (3%; 6% at Month 1 and 0% at Month 6)" ... "base rates of identification of genuine travelers identified as being deceptive in the 6 months before the trial (1 in 1,247 passengers) did not differ during the trial with suspicious signs (1 in 1,219 passengers), or CCE (1 in 1,295 passengers)"

So my reading is 2/3 mock passengers identified as true positives, 1/1000 real passengers identified as false positives.

(With some provisos as noted in the paper)
