As the saying goes, it pays to advertise.
'Advertise' as in jazz yourself up. Sell the sizzle, not the steak.
Thing is, the average polygrapher is just as guilty and the APA encouraged
that behaviour in the first instance.
We were told by our APA Instructors that having completed our 10 week courses,
we were now 'Forensic Psychophysiologists' - that ranks right up there with the
phony PhD scam. Hell, half of the twats cant even spell anything beyond 3 syllables.

Most of them need 2 lines to write their 'letters' - ( I need at least 4 )
