Thank you for the insight...very helpful!

Even if no irrelevant questions are included in the mix, the technique you've described would most likely be scored in the same way as the relevant/irrelevant technique: the polygrapher looks for consistent, specific, and significant reactions to any of the relevant questions. If such reactions are observed to a particular question, then deception is inferred.

Augmenting reactions to a different pair of items during each chart collection would tend to diminish the liklihood that any one question would stand out more than others. However, behavioral countermeasures -- and having an innocuous explanation prepared in advance for any claimed "reactions" -- may well be enough to get one through.

In pre-employment screening, a question about marijuana usage would be a relevant one. It is highly irregular for a relevant question not to be reviewed during the pre-test phase. It is possible that a creative polygrapher in this department is using this question as a "control" stimulus. Alternatively, asking an unreviewed relevant question would be a simple way of rigging a polygraph examination against a particular applicant.

Hello All...

I am getting ready to take a pre-employment poly for LE.  I have read TLBTLD and found it very interesting.  I have heard through the grapevine that the agency I am testing with asks the following questions:

Have you been honest regarding the following:

-employment
-drug use
-sexual past
-education
-training
-financial
-ommissions
-use of marijuana
-etc

I believe this might be a R/I test but it seems these are all relevent questions....am I right here?

Also, I heard that sometimes they may add the mj question in the end and not notifiy you in the pretest...would that then become a control question purely for stimulations purposes?

If this were a R/I test and I were to use radom CMs would that be effective???  Any help would be greatly appreciated!
