I think it’s possible to beat such lie detectors by considering the question in such a way that you get the answer you want. “Did you kill that man?” “No” (mental framing: the knife killed him/he killed himself by annoying me/I’m a different person today/My name is not “you” so it’s technically false, etc)

I would bet that the hesitation caused by doing the mental reframe would be picked up by this.
The counter to this is, always take your time whether you need to or not.
