Partly its that. Partly its about tricking juries, "He failed/refused the polygraph" is a very nice way to discredit someone. At least 5 of the 12 people there will find that concerning and not know its BS.

Any lawyers in the house? I was under the impression that (in the US) refusing to take a polygraph was not considered an admission of guilt though could be grounds for dismissal from federal employment.

What's legal has nothing to do with swaying a jury.

Just like those dogs that indicate the presence of drugs. Except of course when there aren't any. I've had my car searched a couple of times at the Canadian/American border because a dog gave a signal. Given the number of times I've crossed that border the false positive rate must be ridiculously high. Since you don't have much in terms of rights when crossing a border I wondered why they even bother with the pretext…

Oh wow! I've never even considered that. I wonder if the dogs pick up on subtle behavior cues from their handlers, which the handler may not even be aware of. The dog ends up giving a seemingly legit outlet for some unconscious bias.

An officer can give the dog a subtle cue to alert. Happens all the time.

Citizen X is an American drama. If it depicts what you're saying (I've seen it but can't remember it) then it's just another Western dramatization depicting post-Stalin Soviet Union in cliches from the 1930s. In the real life case Citizen X is inspired by[0], nobody was tortured for a conviction, even the guilty man, who was simply put into a cell with a police informer to gather information and questioned normally b…

Post-Stalin Soviet Union clichés, of course. How do you think the wrongly arrested people confessed to the murders in the first place? "At his trial, Kravchenko retracted his confession and maintained his innocence, stating his confession had been obtained under extreme duress."

> How do you think the wrongly arrested people confessed to the murders in the first place?

As in that example with Kravchenko, the same way false confessions occur in every country, pressure in some form from the police who want to convict their prime suspect / clear up a case.

It's indefensible but it's nothing unique to the Soviet Union and it's not uncommon.

What are the chances of an actual spy being able to beat a lie detector? I'd put those at about 100%. So you will end up with nervous people who will increase the size of the haystack with zero chance of identifying the needles, which is a net negative.

> What are the chances of an actual spy being able to beat a lie detector? I'd say not even remotely close to 100%. What is an "actual spy"? Those people are often regular employees with zero relevant training, that are simply recruited by a foreign intelligence agency via pressure, money, or manipulation, and are targeted based on their access to information. I'd say that a huge percentage of them won't be able to b…

What you are referring to are embedded assets. Embedded assets are different than trained spies in intel or counter intel. A trained spy may be a handler of assets but they generally do intel work themselves and usually have some form of cover. A trained agency spy will undoubtedly be able to beat a poly and are trained to do so, on a regular basis. While the accuracy of a poly is too low to be usable for the discerning of truth, they do work to some degree. They are better at telling what you said was true than they are at telling what you said was a lie. So generally if a question is asked and you don't pop then it is fairly safe to assume that you told the truth. Where their completely fail, is sometimes they will pop when you are telling the truth and you can train yourself to not set off the machine when you lie. The problem is it works on the right kind of person in a clean room setting, but that is never the real world, there are just too many variables that are not handled for it to be anything other than a psychops tool, where it just becomes a loose guide on where to dig deeper.

Fun fact, lie detectors are completely ineffective on compulsive liars.

If the opposing side brought up refusing to take a polygraph you would object and ask the judge to explain to the jury why that had to be disregarded, right?

I'll say it again: they don't work.

You can't really use them for anything. A polygraph machine might have an application though: doorstop.

Can't these just be beaten with some breath training and a short training in how to answer? All they measure is your physical reaction, right?

You clench you butt cheeks when they do the calibration when you want something to register as a lie. So you tell a truth and then clench your butt cheeks for calibrating a lie. Thus they get a strong response on a truth/lie and a less strong response on a lie. The other trick is to recall a traumatic event.

The story was around before The Wire.

Yes, in David Simon’s book Homicide: A Year on the Killing Streets, as well as the David Simon series Homicide: Life on the Street. David Simon also created The Wire.

Fine, it's been around since before David Simon cribbed it:

I doubt that any judge would allow that to even be brought up in a trial. If it were, it would probably be an appealable issue that would get the case thrown out.
