What do you think of this?

Tipsters,

I have some concerns about the quality of the experimental method used here, but I wanted to run this by you guys and see what you think.  Since there are always questions about lie detectors in my intro psych classes,and I am about to start Winter session, I wanted to be prepared....

Your thoughtful opinions would be appreciated.

LONDON--Scientists have developed an instant lie detector technique which picks up mini hot flushes around the eyes and could lead to truth tests becoming standard at airport check-ins, the journal Nature reported on Wednesday. In the new tests developed by scientists at the Mayo Clinic in Rochester, Minnesota, a high definition thermal-imaging camera scans a person's face to see if they blush when answering a question. In theory, blood should rush to the eye area of liars, researcher James Levine said, while the innocent remain coolly and calmly unaffected. Experiments in which 20 people were randomly asked to stab a mannequin, rob it of $20 and then profess their innocence, showed the technique to be as effective as existing lie detector, or polygraph, tests. The thermal camera correctly picked out 75 percent of the 'guilty' individuals and 90 percent of the 'innocents', a control group who had no knowledge of the mock crime.
