"We call it the Voight-Kampff test for short"

I read about this prototype sensing device for the twats at the Homeland Insecurity department in the US on Boing Boing (bad enough US authorities have such a belief in their 'lie detector' technology which most psychology lecturers I know find laughable, now they want these stupid things which will never catch a bad guy but will get stressed travellers into trouble for no reason) and I couldn't help but think of the Voight-Kampff test used in Blade Runner to try and detect who was a Replicant.
