Correlating Psychopathy With Speech Patterns

florescent_beige writes "Researchers from Cornell and UBC report that analysis of speech patterns using Wmatrix, along with something called the Dictionary of Affect in Language (see a demo here), shows that psychopaths speak differently from other people, at least statistically (abstract). Although they say that these differences are 'presumably beyond conscious control,' the authors do not say if the method has any predictive use. Regardless, the popular press has already gone headline-nonlinear about it."
