Does that mean the polygrapher can use a "manipulated" chart to let the examinee view their "deception" and then extort information from them if they desire? Then since it is saved reverted to actual, which may be a legitimate "passing" chart...The polygrapher is using "deception".
Since the polygrapher has every examinee sign a release of liability...this allows them to do this. Not saying that all poygraphers do... but just a thought
Since polygraphers feel free to deceive those whom they examine in order to achieve their goals, I wouldn't be surprised, not surprised at all.

It would appear that you missed one sentence in the catalog description, the one that states that all manipulations rervert back to the actual measured chart-- dubious as I am, they do mention it.
Beech Trees,

I would like you to clarify the following points that I read from the Lafayette Co. website
1. Chart Review:
· Ability to view GSC tracing in both manual & automatic mode after the chart has been recorded.
· Change tracing position, sensitivity, color and thickness before and after the chart has been recorded.
· Remove any tracing on the display after the chart has been recorded. All charts revert to original recorded values when closed
Does this imply that the polygrapher can actually ALTER the values on a chart during an exam? If so can the polygrapher change the tracing to show a false "deceptive" pattern to extract more information from the examinee?
2. · You do not need the sensor box attached to open, review, score or report on charts or files.
Is the sensor box what receives the raw data from the pneumo tubes and blood pressure cuff and sweat sensors?
If this is true, can the polygrapher use "stored" information to score any test?
The peer review was very interesting. But what about the Stoelting Co. equipment... any peer review on them?

It takes some nerve on the part of anyone involved in "lie detection" to bring up scientific peer reviews. Whether it's one polygraph instrument manufacturer criticizing another or polygraphers making attacks on CVSA, anyone who brings up peer-reviewed scientific research in an attempt to show that one type of lie detection device is superior to another is guilty of hypocrisy.
As readers of this site know, peer-reviewed scientific research has not shown ANY type of lie detection device to operate at better than chance levels under field conditions.
In the glass city of lie detection, it is amazing how quick these people are to throw stones.
