Scoring algorithms' only utility would be when numerous charts are to be scored as in a study. Performing discriminant analysis on a sampled waveform is actually trivial as far as DSP is concerned. Computerized instruments are by no means a scientific leap; they just provide an opportunity for polygraph operators to fool themselves into thinking that they are "high tech."

Ladies and Gentlemen - Here you have a prime example of the high caliber of intellectual debate you will get from most polygraphers.  They can't defend their position so they resort to childish taunts, crude name calling, and personal attacks.  My name alone gets them so riled up that they can't even use proper grammar when they rant and rave!   

Mr. Williams, 

Or as I like to call you, Dougie Douchebag



"they often default to DECEPTION INDICATED or indicate COUNTERMEASURES have been used when there has been no deception and no use of countermeasures!"

Either you are bold faced lying there or you are clueless.  I would like to think it is the later, but I think the former maybe more the case.  I would say the rest of your post is as well a lie, but I'm laughing too hard at the above quote to take anything more you say seriously.   

I heard they too your license away from someone.  If this is true, I can see why.

Anyway, yea, you lie

Have a nice day, I am done with you, go crawl back under your rock now. 

Absolutely right.  I have 2 digital and 2 analog instruments and they do in fact produce the same charts.  But the digital instrument's scoring algorithms not only DO NOT eliminate examiner bias, they often default to DECEPTION INDICATED or indicate COUNTERMEASURES have been used when there has been no deception and no use of countermeasures!  

I have also run tests without even asking the questions, just clicking on the computer to indicate the questions were asked, and the subject didn't do anything except sit quietly in the chair - and the computer scored DECEPTION or COUNTERMEASURES!  No questions were asked, and no answers were given, but they were all accused of lying or using "countermeasures" by the computer!

adrian,

You are incorrect. There is no difference between an analog and digital instrument; they both produce the same charts. If you are thinking that scoring algorithms somehow eliminate examiner bias, you are dead wrong.

it cant be done. you cannot fool a computerised, properly conducted test. these tests are simply more accurately able to do what law enforcement professionals are already taught to do. i.e they measure physical responses to to questions asked. however, the tests leave out the good cop bad cop routine, they leave out any personal prejudices of the cop toward the subject, they prevent the cop from putting pressure on the subject, bombarding the subject with questions in a rapid fire and desperate fishing expedition to find anything in word or physical reaction that they can twist to fit their fantasy and use against the subject. granted, the old analogue tests were complete bunkum, and easily fooled. but today the science has moved on. the question we should be raising is how accurate are trained police officers and juries by comparison to properly conducted, computerised polygraphs? too many innocents are having their lives torn to shreds because for others it is better to send 9 innocents into hell if it means that just 1 offender is caught and dealt with. well i say, not for any of the 9, or their families it isnt. if you were innocent and faced that living hell yourself you would want to have accepted anything that could point to reasonable doubt and might spare you from that hell. wouldnt you? in the uk for example, in all cases, legally, the police must withhold any evidence which they have gathered and which might prove the defendant is innocent. certain types of serious criminal allegations (historical allegations of child abuse for example) are  tried on the basis of guilty until innocent, and anything the defendant wishes to enter as evidence in their own favour gets ruled as inadmissable. historical allegations often have no real evidence and come down to one persons word against anothers. prosecution dont have to prove their case, only destroy the credabilty of the defendant with the full help and support of the court. they are the easiest cases to secure convictions and make the authorities look good. and with private prosecutions now possible, in many cases theres more money on the table for victim compensation. currently it is too easy to play the system for cold hard cash playing the victim.  polygraphs on both sides would make this harder and protect genuine victims of abuse and protect the innocent from a life of hell. they could also help clear innocents and give them back their lives. (albeit mentally scarred and in need of much help and support to resettle and recover). its not polygraphs that are the problem, it is when and how they are conducted and how the results are used. clearly in many organisations people are abusing their privileges and/or not making use of honest and well trained, professional examiners. clearly polygraphs are being used against subjects already rejected or marked out as someone they wish to remove by one person in the chain of command but who must provide "valid" reason for this to their bosses. any more than three questions requiring a simple yes or no, one word answer (beyond the control questions) is simply no less than a desperate fishing trip by those overseeing the exam trying to find anything they can use against the subject for their own ends. this should not be used an excuse to seek to pour scorn on the use of polygraphs. dig deeper. dig deeper too when anyone says that polygraphs can be beat and ask: has that individual actually got proof that they themselves did either beat the polygraph, or they have been witness to such an event, and can they provide the proof? and when was this? and was it an analogue test or computerised? dont rely on hearsay and missinformation like russ. dont even take my own word for it as someone who took a properly conducted polygraph in my own home, off my own back, without coercion, without dictating the test questions to the examiner and passed. i urge you to do your own research.

In September of last year, U.S. News and World Report writer Elizabeth Flock interviewed both Russ Tice and myself regarding polygraphy for an article titled, "NSA Whistleblower Reveals How to Beat a Polygraph Test":

http://www.usnews.com/news/blogs/washington-whispers/2012/09/25/nsa-whistleblowe...

On 26 September 2012, American Polygraph Association president Barry Cushman posted a link and the full text of the article to the PolygraphPlace.com private forum, an archive of which (94 mb ZIP) was recently posted to AntiPolygraph.org. Cushman titled his post "NSA whistleblower (making things up...)." (The message thread is found in folder 2 of the archive, and a PDF "print" is attached to this post.)

Dan Mangan replied to Cushman:

Cushman, who is also registered on the AntiPolygraph.org message board, never provided an explanation.

Barry, do you still believe that Russ Tice is "making stuff up?" Would you care to explain?

In an interview with Sibel Edmonds' Boiling Frogs show, NSA whistleblower Russ Tice mentions (at 55:38) that contacts inside the NSA who are providing him information are all beating the polygraph:

Quote:


Perhaps emboldened by Edward Snowden's whistleblowing, Tice makes explosive new revelations in the interview, including the fact that the NSA wiretapped Barack Obama in the summer of 2004 when he was running for the U.S. Senate. Tice alleges that many other senior government officials have also been targeted and he names names. Here's a partial transcript, beginning at 45:35:
