Detecting Deception with LIWC Lab

Detecting deception is an important skill, yet reviews of the psychological literature on the detection of deception tend to find accuracy rates of between 45 and 60% (cf., DePaulo & Friedman, 1998). A computerized text analysis, the Linguistic Inquiry Word Count (LIWC) offers one technological solution. Newman et al. (2003) used the LIWC to detect deception in five studies. Deceptive communications were characterized by fewer first person singular pronouns, third person pronouns, exclusive words (but, except, without), and more negative emotion words.

Through support from the Army Research Laboratory, we have replicated Newman et al.'s studies using different topics and different communication mediums.
