The Polygraph Isn't Perfect |

Scientists from the National Research Council say the polygraph
hasn't advanced much since it was first used in World War I. But since
1950, federal agencies have used it to screen for spies and other
security risks. (Use by private employers was outlawed in 1988.)
The government's use of the polygraph to test people for intelligence
or security work has mushroomed, and tens of thousands of people are
subjected to the test each year.
The panel says the test is more useful in criminal investigations where
questions are specific. Broader questions such as "Have you ever
violated security rules?" may trigger false positives by innocent
people who worry about breaking rules.
