A Cheaper Alternative to the Polygraph

I got another confession. That makes 8 since I started the polygraph last year  . I guess polygraph dosn't work.

Congrats, polylawman.  I do hope the confession's not false (that does happen sometimes, you know).

BTW, no one here has said the polygraph isn't useful for eliciting confessions.  But a photocopier set to print out "he's lying!" has been used in the same manner.  That's called an "interrogation prop".

Elicited confessions has nothing to do with whether the polygraph can actually detect lying with any accuracy.
