If I'm understanding this correctly, it essentially tries to tell if someone agrees with a statement ("I want to end my life") by looking at "preconscious" brain signals, regardless of what the interviewee answers consciously. So is it like an MRI for lie detectors? I wonder how it compares to the faults of traditional lie detectors. Besides the weird "precog" minority report vibes, it makes for an interesting validation problem.
