I used to love watching the show Lie to Me. For those who clearly do not watch enough television, its now cancelled tv show about a psychologist who is an expert in detecting lies through subtle clues in body language. He uses his skills to help solve crimes. I have never taken a psych class before, so when I heard that the show was based off of a the work of a real person (Paul Ekman), I was convinced that everything they said on the show must be true. I was sad to see that the textbook rejects this notion and that even so called "experts" often do little better than chance when determining whether or not someone is lying. Why not? Although the textbook does state that there are certain primary emotions whose expressions are universal (That is, that a surprised face is a surprised face everywhere), lying is not an emotion. Furthermore, there is no emotion universally associated with lying. Perhaps Ekman was actually reading people's emotions through microexpressions and just happened to be really good at interpreting them. I wish the textbook had more on microexpressions and body language.
