>While the scientific community highly endorses double-blind testing, it can have disastrous effects on canine teams. As there is no way to determine whether the canine responded correctly at the time of the alert, the question is, should the handler reward the canine? This is a vital question due to the fact that detection canines are largely trained on a fixed ratio reward system where the canine is rewarded immediately for almost every correct response.
A measurement system that only works when you can't calibrate it isn't a useful system.
Also we live in a world where instantaneous communication at arbitrary locations is possible. How hard would it be to make an app where the evaluator can check if the canine's response warrants a treat?
