I'm doing well enough, you? I like your art, especially the "Lorax" series!

Most of what constitutes a "lie detector" test mostly resembles a cold reading (like a fortune-teller) with intimidation from the examiner. After having been raised by an abusive alcoholic, intimidation is not much of an issue. Having worked in the "Fortune-Teller" trade, a cold or warm reading is not much of an issue, either.

I believe AS could interfere with polygraph indicators, including establishing a base-line.

The whole need to sit very very still for a period of time would raise my tension levels, and I do not think in my case it would actually be achievable to sit that still that long.

They do not work at all. Why they they shall now work specific with Aspies?

In Germany the courts are not allow to use "evidence" of lie detector, because of the lack of reliability, most recently in a decision of the BGH (Federal Court of Justice) of 2003: http://www.jusline.de/pdf/de/entscheidu ... _32702.pdf

i'm ok. life is rolling along in self-imposed and preferred hermitism. working on a big 9ft painting at present. I am ok so long as i am relegated to painting and WP, special interests and developmental delays that render me not far off this side of 9 years old or so.
then, i seem to function fairly well in the world.....


although i was considering applying for the armed forces or the police force or something....


i chuckle at the new signature.....(having a spot of fun are we??)

Isn't the lack of a time limit one of their weapons!?!?!? THINK ABOUT IT!

According to HowStuffWorks,
"the examiner looks to see how the person's heart rate, blood pressure, respiratory rate and electro-dermal activity (sweatiness, in this case of the fingers) change in comparison to normal levels."

That does not seem like enough factors to me. Suppose their was a murder investigation, and the person asks "did you do it?", wouldn't your stress levels be high regardless of weather you say yes or no? I mean you are not going to be relieved by telling the truth because of the question they are asking, so wouldn't both the truth and whats false appear to be a lie because of a stressful question?

Also I think you can tell when an aspie is lying if they look at you in the eye. Suppose the person does not usually look you in the eye when telling the truth, but when asked a question they all of a sudden are looking you in the eye ( that means they are thinking hard about how to react and are purposely trying to look you in the eye because they are lying.)

That is only one type of lie detector test, they have one that measures brain activity too.

How would you react to hour after hour of repeated questions? Eventually, you'd likely confess to something just to get out of the room!

Actually, limiting the time puts all the burden back on the examiner.

Oh, and always have your attorney present during questioning.

Me too. I'm a really good liar, but knowing that I'd be tested on it would throw off the polygraph's ability to establish a baseline because I'd already be so stressed out.

Interesting. I'd have thought so.

I heard lie detector test results are inaccurate and cannot be trusted in any circumstance. Do not be fooled into taking one. They are meaningless.

I'd probably be so anxious about giving a false positive that I'd fail while telling the truth. On the other hand I could probably tell a simple lie without any anxiety elevated above the baseline while telling the truth. I image people who lie all the time would be able to pass a polygraph easily.

Your baseline is established by asking you simple things that you should answer honestly. If you are stressed when establishing your baseline, you will create a baseline that matches your stress levels. If you are lying, it will still deviate from your baseline, by how much is whether or not they can call it positive, and that might be indeterminate. You can't generate a false positive very easily, in fact, it is easier to generate a false negative.
