I have to join those who are skeptical of this. Doesn't sound very scientifically based to me, especially given that it's been done by a professor of computer science and engineering and a professor of communication, neither of which fields have much if anything to do with evaluating or predicting behavior. If it's "biometrics" then shouldn't a biologist of some sort be involved? And behavior clearly falls more within the bailiwick of the psychological arts and sciences. A psychologist should be in charge of this type of research. Sounds like someone's looking for (or has already landed) research grants from the feds.

I'll bet you anything those whose tests came up positive were entered into a government data base, where that info will come up if they apply for a job, or a loan, or a passport, or god knows what else.
