Which of the following is true regarding lie detectors?
A) Lie detectors are accepted as valid evidence in most U.S. courts, but not in other countries.
B) Research suggests that traditional polygraphs are about 78% accurate as lie detectors.
C) Polygraphs are able to detect arousal, but are not valid indicators of lying.
D) Researchers have been unable to identify any potential lie detector replacements for the polygraph.
Answer: C
Rationale: Although many support its use, controlled studies of polygraph recordings suggest that they provide evidence of arousal (that is what they are designed to do), but they are not valid indicators of lying. Newer brain imaging techniques may turn out to be more accurate. Currently, most U.S. courts do not accept polygraph results as valid evidence.
