Telling the truth but failed voces stress...what's the problem?

Question

I have never used or sold drugs in any shape or form but today I took a voice stress test for a Police job and it's saying it detected stress from the 2 question about drug use and the selling of drug. I repeat in my 27 yrs on this earth I have never used or sold drugs. I have been a stand up guy my whole life and this test breaks my spirits. Is this possible?

Answer 1

Voice stress tests are notoriously unreliable.

They just detect if you are nervous or not (and don't even neccessarily do that all that accurately), so if your mind was going "I hope I pass this. Help! I wonder what happens if I get this drugs question wrong" (which is an entirely reasonable thing to be thinking), then you'll have seemed stressed, and might have flubbed that question.
