It seems that The Eagles were on to something when they sang that "there ain't no way to hide your lyin' eyes," because researchers are working on eye-tracking technology which will detect dishonesty better than a traditional polygraph test.

This promising-sounding technology is being researched by some folks at the University of Utah:

The researchers determined that lying requires more work than telling the truth, so they look for indications that the subject is working hard. For example, a person who is being dishonest may have dilated pupils and take longer to read and answer the questions.

Of course, it'll be a little while before this eye-tracking lie-detection system is perfected, so don't start worrying about someone scanning your eyes for fibs during a conversation just yet. [Physorg via Dvice via Neatorama]
