Thermal Imaging Lie Detector In Development 183
beaverdownunder writes with this quote from the BBC:
"A sophisticated new camera system can detect lies just by watching our faces as we talk, experts say. The computerized system uses a simple video camera, a high-resolution thermal imaging sensor and a suite of algorithms. ... It successfully discriminates between truth and lies in about two-thirds of cases, said lead researcher Professor Hassan Ugail from Bradford University. ... We give our emotions away in our eye movements, dilated pupils, biting or pressing together our lips, wrinkling our noses, breathing heavily, swallowing, blinking and facial asymmetry. And these are just the visible signs seen by the camera. Even swelling blood vessels around our eyes betray us, and the thermal sensor spots them too."

Great job weaving some bigotry and flame-baiting into an otherwise reasonable post.

"It was terribly dangerous to let your thoughts wander when you were in any public place or within range of a telescreen. The smallest thing could give you away. A nervous tic, an unconscious look of anxiety, a habit of muttering to yourself, anything that carried with it the suggestion of abnormality, of having something to hide. In any case, to wear an improper expression on your face, was itself a punishable offense. There was even a word for it in Newspeak: facecrime"
Why bother? It would show nothing. Sociopaths can trivially pass these kinds of tests.
Indeed, the greatest con men not only make their marks believe the lies - they believe the lies themselves, at least while they're being spoken. How do you think you get to become part of the Inner Party in the first place? Unsufficient to be doubleplusgood duckspeaker, must be doubleplusgood doublethinker.

Damn, I'll have to find another excuse for doing those things.

Despite what your mommy told you, you have no "right" to not be made fun of for believing in an invisible sky-daddy.

Which, of course, raises plenty of important epistemological concerns: chiefly, what is a lie? Perhaps we could say it is speaking with the intent to deceive. But in what way is the speaker attempting to deceive, which pieces of information does he actually wish to conceal and which bits of misinformation are merely the detritus of a twisted story?
Even if an actual lie detector were to exist, it would be up to the operator to decide what it means. Nobody is really prepared to deal with that sort of weighty thinking on a consistently sound basis, especially not a policeman or a judge.

Not bigotry. He chose an apt example that clashes with your worldview. He isn't intolerant of you having that worldview - he just disagrees with you and isn't trying to hide it. You, on the other hand, are being a bigot by attacking him because he doesn't believe in what you believe.
