After decades of exile from US courts, the science of lie detection is gaining new acceptance. But the federal government wants to put a stop to it, and the US Supreme Court has now agreed to consider a request from the Department of Justice to bar the technology from military courts.
Uncertainties surround the science of lie detection, which uses a device called polygraph. In 1991, President George Bush banned lie detector evidence in military courts. But that ban has since been overturned by the US Court of Military Appeals, which ruled that it restricts defendants’ rights to present evidence of their innocence.
In the past two years, some federal courts have also ruled ’that polygraph evidence can be heard. This follows a decision by the Supreme Court in 1993 that gave federal judges more discretion to decide on the admissibility of evidence.
A polygraph consists of monitors for pulse rate, sweating and breathing rate.
A. Highly-educated college students can beat the polygraph
B. College students do not want to beat the polygraph
C. Polygraph is reliable
D. Polygraph failed to detect the lies of college students
