As most of you know, you could write books on what I don't know about polygraphy and mostly, I lurk in and around a different area.  Of recent interest though is this;  I was looking on various polygraph manufacturers websites and I noted that the Stoelting Co is advertising loudly that they do NOT use this deception detecting (?) algorithm used by Axciton and Lafayette.  They then offer supporting evidence they say refutes the claims that this algorithm works at all.  Again, I know little or nothing about the polygraph.  What I do note is that they seem to be fighting amongst each other.

Stay safe.
