This fMRI technology exists and it's superior to the polygraph, which the CIA and other foreign spies are trained to 'beat' (and do so, very easily) The MRI based lie detection cannot be defeated, and has an accuracy of 90% or higher.  The accuracy is assesed by the ability of a neurology panel to be able to determine if they are lying or not This is why you have to extreme-vet the neurologists also And why you also have to anonymize the person being scanned in a double-blind kind of situation, because that way you don't influence the MD's / neurologists with politics for example.    It might even be helpful to have a lightweight MRI scanner of the neurologist (scan the scanner), so that you can see them side by side; but these MDs can only have a certain amount of exposure, so they'd have to do only a few assessments per month and be traded out.  This could be a very good thing, becasue it would eliminate the possiblity of a RUBBER STAMPER  The most improtant 'weak link' is to guard against rubber stamper neurologists who approve everyone or who are paid to approve certain applicants BTW--this MRI technology can detect PSYCHOPATHY / PSYCHOPATHS as well.  We should exclude all psychopaths from the US Government, --OR-- give them a position that exploits their gifts but limits their POLICY, PROCESS OR POLITICAL INFLUENCE POTENTIALITIES
