I wonder how reliable these other technologies will be either because won't they only work if someone is consciously lying? What if there are situations where eye witness testimony isn't the truth but the witness believes it is? Loftus and Palmer's study demonstrated that witnesses will try to fill in gaps if they don't know the details to help others. Would these technologies be able to put up these uncertainties too do you think?
Polygraph tests- so-called "lie detectors"--are typically based on detecting autonomic reactions and are considered unreliable.
That's why psychologists have been cataloging clues to deception--such as facial expressions, body language and linguistics--to help hook the dishonest. From this research, psychologists are developing new detection tools such as software to analyze facial expressions and writing style.
