When perfected it will replace the polygraph

   

It's extremely limited in its functionality as it is.... unless one can accurately map where the "red stripey pattern" memory is stored in all people, or the "location of my chopped up spouse" memory, they can only compare the signals to what they already know.

The application to paraplegics seems very feasible, and useful.

   

There is a saying my wife tells me, "When you tell the truth you don't have to remember what you have said." Lies and deception require more work than the truth, that is how this works basically. Your throwing off more 'heat' when you lie because your accessing different parts of the brain that deal with creativity, memory, and cogitative conditioning. You know when you lie and it feel 'unnatural' and you get a feeling in your gut, why? You conscious is rallying against what your doing as the baseline for all activity is the truth. It is what we base reality upon and we have a reaction when the truth is warped.

Most people are good, honest and aspire to work with others because we as humans are social animals. To lie is a defence or a shield vs harsh realities and to some people that comes naturally to raise that shield but it will still a have tell tale signature in the brain patterns.

   

Counterpoint, I give you a card and then show you the deck of cards and ask if this card is the one your holding. If you say no to every card you will still have an immediate response when you see your card as you have to process it, is it your card? It's not that you care that it is your card it is that you have to remember which one is yours. Memory can be linked you lying. This has been demonstrated when you tell a lie and your eyes move up and to the right as your accessing the left side of the brain. It is a conditioned and unconscious response.

   

Scape in some people.. the answer is yes.. You can train yourself to beat a polygraph.. and you can train you body not to react in certain ways..... Also doesn't really work with pycho and sociopathic people....

   

But you can't train to use your brain differently. This brain scan will be able to detect the changes which are impossible to control....

   

With proper training it is possible. In addition, since they would need to establish a baseline reading (indicate by the respondant giving known truths & lies) a person wishing to conceal his lies could easily confuse the machine simply by manipulating his thoughts as he gives verbal responses. I don't believe this technology would ever be addmissable in court much like a polygraph. It will certainly have a plethora of medical uses though.

   

Sounds like the same pseudo-psychological bullshit that the polygraph is based on, only seemingly more elaborate.

Most people know how to lie, and most people can lie quite well. What is claimed that everyone gives off tell-tale signals may or may not be true, no one really knows, because if they are in fact there, they are different for everyone thus there is no way to be able to establish if someone is lying or not.

However, this very line will be repeated by any polygrapher for the specific reason of making the subject believe in the polygraph, and theoretically when you believe in the polygraph, and when asked about ones supposed involvement with an action theoretically ones level of nervousness will spike, then the polygraphers further make the assumption that an innocent person will not be able to tell the difference between a 'control' question and a specific question.

That were two people asked the questions have you stolen items before, and did you rob the bank, the innocent person will have about an equal level of nervousness for both, while the guilty person while be far more nervous about the robbing the bank question.

And if thats not enough to shake the credibility of any polygraph test theres the question of countermeasures...

So considering the hypothetical nature of the "tendency towards honesty" and the reason it was proposed and assumed to be true, I tend not to trust any report which makes such claims.

   

The purpose of the card trick that the polygraphers use is to establish their credibility, not because it actually clues them into whether or not someone is lying. One can reduce ones response to such a question as a matter of reflexes, much like when someone is talking on the phone with someone saying "yeah...yup...exactly" without listening to a single word that is being said.

I suggest reading this website over http://antipolygraph.org/

   

That is the exact premise investigators use when interrogating a witness or a suspect. They will keep asking the same basic questions, at different times during an interrogation. After time, the suspect commonly slips up and is therefore caught in a lie.

This is an interesting idea, but I agree with DerbyX, I don't see it being admissable in court.

   

Canucker,

A better technique than asking the same question over and over again, (try it out on your kids if you have any to "test" the theory) is to have the person being interviewed run through their story two or three times.

Then, make them run through the story in reverse or in a chronologically disordered pattern. In a deceitful story, the errors and mistakes will crop up in huge numbers.

Besides, polygraph tests are admissable in the court of public opinion. Have you never watched an episode of Maury Povich?

   

Only the people on that show, and others, should have electrodes inserted beneath the skull for a slightly different reason....

   

HA! That's a good idea.



Once or twice before when there was nothing else on.... LOL

   

In any story mistakes will appear, it may be true that more mistakes will appear in a lie (however, good liars will know to keep the lie simple, and generally close to the truth because of it) one cannot use it to judge the veracity of a statement unless you know the person.

   

But you can't control the fact that you know it's a lie, and that's likely what this method will be able to detect.

As you as you can be at hiding the fact that you're lying, the fact that you know you're not telling the truth will be a disadvantage, if only at a neurological level.
