Lie Detector (Stargate SG-1)

In the Science fiction show Stagate SG1 the Tok'ra use an Advance from of lie detector. The person being interagated with the Lie detector does not have to answer yes or no questions but can be asked anything. It can even detect false statements even if the subject themselves don't know that they are lieing. Because of this they are able to detect if false memories have been implanted in the subject by the Goa'uld as was the case when it was being used in a joint operation by the Tok'ra and Stargate Command when trying to detect which people had been "programed" to kill the president upon meeting with the leader of the Tok'ra's High council.
