Can the polygraph tech manipulate the test

[sailor6535]

Everyone talks about "beating the test" but what about law enforcement that goes fishing?  Is there a way for a polygrapher to manipulate the test to show deceptive to use it to get a confession?

Also on the LX3000, how often does it need to be calibrated, and is the functionality still 6 months?

In the words of Dr. James Blascovitch, one of the members of the National Research Council's Committee to Review the Scientific Evidence on the polygraph, "...every examiner I asked at DoDPI, 'If you wanted someone to fail this test, could you have them do it, physiologically?' they said 'yes.'"

There have also been instances where different examiners studied the same charts and gave different opiniongs regarding truth or deception.

With that in mind it seems likely an examiner wouldn't have to do very much of anything other than give a "deception indicated" score at the end of the test.

Sounds to me like you are trying to project your lack of morals and your desire to cheat on a polygraph test onto polygraphers.

Since Polygraphy is a interrogation tool geared to benefit the Polygraph operator with his interrogation.
The results can be influenced by the Polygraph operator and they do it repeatedly.
