> Meanwhile, as CBS Seattle first reported, some scientists are claiming they can “hack” information out of a subject’s brain, and engage in lie detection, by using a simple “brain computer interface”—biofeedback brain-wave readers that are increasingly used to control computers and are available off the shelf for only $300. According to the scientists, a “guilty knowledge test” based on a particular brain wave, the P300, “has a promising use within interrogation protocols that enable detection of potential criminal details held by the suspect.”

> Five or so years ago, we looked at this issue in great depth—consulting with experts, hosting a forum, and filing a Freedom of Information Act Request. Around that time several companies were aggressively marketing the technology as lie detectors and for other purposes. One of our concerns was that the technology might be applied by our national security agencies against suspects in the “war on terror,” who would then be mistreated based on inaccurate results. Our FOIA request attempting to find out if that was true did not yield any answers.
