However, researchers have found limitations to these tests as subjects voluntarily control their reaction time, deception can still occur within the response deadline, and the test itself lacks physiological recording. "[5], The control question test, also known as the probable lie test, was developed to overcome or mitigate the problems with the relevant-irrelevant testing method. The CQT may be vulnerable to being conducted in an interrogation-like fashion. He later entered the field of forensic psychiatry.
