suethem,

Regarding flatulence and polygraphy, see the discussion thread Countermeasure Accusation.

Saidme,

As a forensic psychophysiologist (or whatever they call you guys ) you must be concerned with science.
  
Flatulence happens!  Science says so!  It has certainly happened during polygraph exams.  

Since you can detect countermeasures, such as the cheek squeeze, for lack of a better term, surely you can detect the simple fart.

Does a fart look different on the charts than other countermeasures?

Do squeekers look different than the silent but deadlies?  

How many times have you detected the fart countermeasure?

Let me guess, only the ones that confessed?

Or did you count the ones that you could smell too?

I guess you'll need to have your clients eat beans as a new CM.   :)

George,

What kind of effect would flatulence have on a polygraph test?

I looked up flatulence online and found that the average range of occurrences is 14 to 23 times per day.  

It strikes me that applicants could accidently spike the 'test' results due to a natural release of built up gas.

Any thoughts?
