They say a picture is worth a thousand words—and researchers
have found a video can be worth even more. A recent
article talks about research
that was conducted using videos of Lance Armstrong where he denied doping, as
well as the video where he finally confessed, taken from the Oprah
Winfrey interview (see confession clip below). Researchers put the videos through
a lie detector program to see the results.
The videos passed through the lie detector computer program and “revealed consistent patterns of behavior.” When Armstrong lied and denied allegations of doping, the computer detected patterns and revealed that Armstrong was lying. “Among the few, subtle patterns that Armstrong unwittingly repeated when lying were shaking his head, blinking and pressing his lips together.” When Armstrong confessed, the computer did not detect these same patterns.
