iologist's that there is no specific lie response. Basically, no specific action has been identified and allocated as an irrepressible deceptive cue. This seems to be very contradicting to the whole purpose of the polygraph test. The fact that the polygraph is wide open to interpretation crates invalidity from the start. Although alterations have been made to protect the validity an minimize the error of the polygraph, the results are still dependant of the subjects physiological response. Although research has shown that these alterations do in fact minimize the inaccuracy of the results, no matter what changes are made, there is still a minimal possibility that one can wittingly breach the barriers. Even with the alterations the results however, are still open to interpretation. The possible bias of the interpreter that precedes the initial tests can be a confounding factor as well. The fact that there is no way to control ones interpretation is an open highway for error. Until science can uncover an unbiased and standardized approach to the interpretation of what specifically constitutes as a deceptive cue, I feel that polygraphs should not be used or held in favor as evidence in the court of law. ...
