Eye tracking system looks deep into your eyes - can tell if you’re lying

SMI RED-oem Remote Eye Tracking platform render. (via SMI)


Law enforcement and federal agencies have been using polygraph machines to detect lies since Cesare Lombroso introduced his blood pressure device back in 1895. Before that? Torture was used as the best method to detect fibs (still is to some extent). Just ask any witch that was present at the Salem Trials and they could probably tell it didn’t work that well. Some analysts will tell you that the eyes are the gateway in detecting if someone is telling the truth or not. They claim the rate a person blinks is a telltale sign of lying as well as not making eye contact or even looking up and to the left or right may be an indication of false pretenses. Some of the early pioneers of computerized polygraph have banded together to form a company, known as Converus, which is developing a new platform that tracks eye movement to detect deception.


The soon-to-be-released EyeDetect device is outfitted with German-based SMI’s (SensoMotoric Instruments) RED-oem Eye Tracking 3D camera system that tracks gaze, eye movement and pupil dilation down to 1/10 of a millimeter. According to Converus, lying causes minute changes in the eye’s behavior because it induces ‘cognitive load’ (psychology- load related to executive control of working memory), which has an effect on eye movement. Think of it like computer RAM that holds on to pieces of data before being replaced by different programs. EyeDetect captures that ocular data and analyses it to assess the ‘likelihood’ of deception while ‘suspects’ answer a series of true or false questions. The company claims the system has an accuracy rate of 85%, which is pretty high in terms of reliability but most courts in the US still don’t allow polygraph tests submitted as evidence. Converus is set to launch their device in April of this year, with Mexico as its first test subject. Businesses will use it for pre-employment screening as well as using it for random testing on employees to weed-out those individuals that accept bribes or are involved in other nefarious activities (there goes police officers and government officials).

    Some employers are likely to abuse it, simply because they are human and it is easy to

    abuse power.

    They may (say) ask something like "will you disclose your employer's secrets assuming your employer is doing nothing illegal?") and that may be a valid question, but maybe some employers will just ask "will you disclose your employer's secrets".

    Disclosing secrets if the employer is doing something illegal may be morally right, and possibly or possibly not legally right, depending on the specific country.

    I blame John Grisham for such thoughts : )

    Also, some may stray into areas they should not, e.g. asking your thoughts on (say) whether you think alcohol should be legalized (if this was prohibition time).

    The point being, that it was always legal to _think_ that alcohol should be legalized.

    _Thinking_ something, and _doing_ something are two different things.

    Without freedom of thought, we cannot work towards changing legislation over time.

    Fair enough, but as I stated, refusal is usually a flag of suspicion.

    That said, we live in a country where we do have the freedom of choice.  I hope we never lose that freedom.

    I normally steer clear of politics at this site, but I feel compelled to say the following:  IMO requiring someone to take a polygraph test as a condition of employment violates several fundamental American values.  Specifically, it violates the Fifth Amendment (you cannot be compelled to give evidence against yourself), the Fourth Amendment (freedom from unreasonable search and seizure without probable cause), and the Presumption of Innocence (you are innocent until proven guilty).  These are fundamental values put into the Constitution by our founders to protect against abusive government.

     

    Many brave patriots have suffered and/or died fighting for these fundamental American values.  Citizens need to keep fighting for these values, or these freedoms will be lost.  IMO when people choose to work for organizations that violate these values, the values are eroded.  Sure, it's legal for non-government organizations to require lie detector tests, but IMO it shows contempt for American values and I don't want to be involved with such an organization.

     

    The idea that "refusal is usually a flag of suspicion" suggests to me that the suspicious person does not understand and/or does not believe in Presumption of Innocence, the Fifth Amendment, and/or the Fourth.  It also suggest that the organization has a culture of suspicion and paranoia and would be an unhealthy place to work.  It also suggests that if I were to join such an organization, it would be hard to find colleagues whose values I share and it would be an unpleasant place to work.

    Every choice has consequences.  As long as you can accept the result of your decision, you have every right to make it.

    Unfortunately, some decisions result in some very unfair results.  Only the people who make the rules can assess the fairness of it all.
