1904,

Yes, yes, and off the top of my head, I think so.  

The APA doesn't "accredit" scoring systems.  There are two that have been "validated" scientifically: the Utah Scoring System and the (now) DACA Scoring System.  There is another that shows much promise (and perhaps better reliability), but that's not my work, so it would be improper for me to comment.  One could argue that the Backster system has been validated as well; however, it isn't as accurate as the other two.  (There are many variables to consider when talking about a scoring system, and sometimes decisions come down to one's philosophical perspective.  For example, there will always be an error rate in any test.  The question is then, what types of errors is one willing to make.  With polygraph, the question revolves around the perceived costs of false positives and false negatives.)

The Utah clan has consistently shown that the computer outperforms all but the best hand-scorers.  Whether that was published in a peer-reviewed journal escapes me, but science is science whether or not it's peer-reviewed.  (I think that's a straw man often raised.  With that said, peer review is an essential part science.)

Okay, back to work.  Pray I don't throw a computer out the window - although, I do feel a little better now.
