Lie detectors are most definitely one big scam. The one running the machine is the main input. Also, dogs don’t work as they get alerts from the trainer and fingerprints are not accurate at all.
Polygraphs are stone age tools to detect obfuscation and untruths. But far better things exist today. They are based on MRI scanners that observe neuron activity in the brain. They do still use the control questions at the start of the interview to establish baseline responses. Those questions rely on the interviewer KNOWING the correct answers.
After that, regions of the brain not involved in rote response, the parts that supply imagination, light up like a christmas tree when utilized in an untruthful response.
When you recount memory very predictable pathways are employed. When you lie, other functions with distinctive signatures to these machines are used.
We cannot yet pull memories from the brain. But we can tell IF what you speak out loud IS a memory. Or a fabrication.
@Lowell – Thanks for that description of FMRI as “lie detector” – I hadn’t heard about that.
In your opinion, do you think it possible to fake the machine and operator out by visualizing fictitious images when making truthful replies, thereby making all replies appear to be untrue?
Lowell,
Is it possible someone could brainwash themselves thoroughly enough to anticipate the important questions by rehearsing the lies and basically committing them to memory, to the point that it would at least obfuscate the readings?
Al beat me to it.
Waterboarding works though.
I have known people who actually believed their lies, so they could have easily passed these tests. None of them were criminals, but having worked in the courts for many years, the criminals did seem to believe their lies too.
A car battery to the testicles works best. Or so I’ve been told.
🎯 How about this: 🎯
“State your name.”
-breath in very deep, twitch your fingers, move around.
Wouldn’t the lie detector register that control question as normal, so when asked a questions you wanted to lie to, but you relaxed and didn’t move much, register as being truthful?
🎯🎯🎯 Besides, if you are asked a question, “Did you murder so-and-so?” Most people WOULD be nervous b/c they would be afraid of going to jail for something they didn’t do. It doesn’t mean guilt, we can’t measure guilt. You can react nervously for any number of reasons.
It’s like the gay people doing an experiment of putting on a measuring device on a straight man’s penis, then making him watch gay porn. If the guage increases, he is aroused and secretly GAY. Nooooo, it just means he’s got something on his penis and gets excited thinking about sex.
SCAM!
@ Uncle Al
These things (machines) are so far beyond a polygraph it just ain’t funny. You can’t beat them by ‘pre conditioning’ your response as that also shows as a non typical usage area of the cortex as opposed to recall from short or long term memory. The thoughts we use to tell an untruth fire off in different parts of the brain, and the connections drawn in that real time display, as they propagate to the speech centers show them as lies.
We are making quite some progress into deciphering the functions of the brain on a gross level. Lying/ not lying has turned out to be a specific area that has bourn a lot of fruit. Funny that would be an area of intense research, huh?
I do know that writing a lie is much more difficult to detect. The connections from memory to muscle action to scribe or type are not nearly as well defined.
I might get a random one this month, our staff was put on notice, I’ll report if I’m selected. 🙂
Should I open a fakebook account and wikileaks account before hand?
Bwhahahahahaha!
@Lowell – Thanks again. Very interesting. At least for the moment FMRI machinery is expensive and non-portable! I assume the buggy software algorithm from last year has been fixed…
Oops. Forgot to add the link to the fMRI bugs could upend years of research article on The Register.
