Brain scans show subconscious preferences of voters David Edwards and Mike Sheehan Do people tell the truth to pollsters? One group is doing brain scans of potential voters to find that out, as ABC News reports on "the next frontier in political polling." Lucid Systems, a marketing research company, used brain-measuring techniques on volunteer subjects (and potential voters) as portions of the recent New Hampshire Democratic debate were aired on a monitor, and, in another test, pictures of the candidates were displayed. Some were surprised by readings that indicated their subconscious minds weren't as keen on candidates' statements as they verbally expressed. "As we grow up," notes Lucid's Dr. Fernando Miranda, "and we learn to be politically correct, we learn to use judgment, we learn to say the appropriate things, then all these other layers are covering the unspoken truth."
