This is the problem with detecting lying based on verbal cues: they're really easy to fabricate. The most reliable way to detect lying is by picking up on a person's involuntary nonverbal cues. If you are good enough at picking up on them, you can easily tell when someone is lying.

If you're interested in this subject, I'd highly recommend checking out "Telling Lies" by Paul Ekman: http://books.google.com/books?id=7I_wDDfrwCgC&dq=ekman+telling+lies&printsec=frontcover&source=bn&hl=en&ei=T7tuTJPoC4m8sAPeu6mhCw&sa=X&oi=book_result&ct=result&resnum=4&ved=0CC4Q6AEwAw#v=onepage&q&f=false http://books.google.com/books?id=7I_wDDfrwCgC&dq=ekman+t...

- j_baker 16y agoThese cues can be suppressed, and most people do so naturally without any practice. The thing is that these cues happen unconsciously. They usually show up before the conscious intellect can suppress them. Let me give you an example. Oliver North was summoned to Congress to testify about the whole Iran Contra affair. I forget what the question was, but the important part was North's response. If you watch closely, you can see his lower lip extend below his upper lip for a split second: he pouted. He was upset by the question somehow, but didn't want to show it, so he quickly suppressed it. Apart from psychopaths, there are very few people (less than 1%) who can totally suppress these types of cues.

- quanticle 16y agoThe problem with non-verbal cues is that one has to have video or be physically present in the room to observe them. The paper was conducting an analysis of investor conference calls, where the investors on the other side of the line had no idea what sort of gestures the executive was making.
