Common questions
Why has no court admitted No Lie MRI evidence as substantive proof?+
Courts applying reliability standards such as Daubert or Frye have found fMRI lie detection lacks established real-world error rates and has not been shown reliable outside controlled laboratory conditions, the same problem that has kept polygraph evidence largely excluded.
What distinguishes No Lie MRI from Cephos?+
Both companies offered a similar commercial fMRI-based lie detection service around the same period. Neither succeeded in getting its results admitted as substantive courtroom evidence in the cases that tested the question.
