Speech patterns of a psychopath
Psychopaths make up about one percent of the general population and their skill at manipulation makes them particularly dangerous, but a team of researchers headed by Jeffrey Hancock at Cornell University believes they may have found a way to spot a psychopath by the one thing they can’t completely control: their speech patterns.
Psychopaths are typically profoundly selfish and lack emotion. “In lay terms, psychopaths seem to have little or no ‘conscience,'” write the researchers in a study published online in the journal Legal and Criminological Psychology.
Here’s a list of the characteristics they found after running their interviews through a computer analysis:
- Psychopaths describe their crimes in the past tense more often than and use “um” and “uh” – also known as dysfluencies – more often the researchers believe because they are trying to sound more sane.
- Psychopaths tend to use more cause-and-effect descriptors in their speech, such as “because” and “so that.”
- Psychopaths use twice as many words relating to the satisfaction of basic needs like food and shelter rather than “…higher-level needs, such as family, religion, spirituality, and self-esteem.”
Such analysis may also prove useful to investigations searching social media sites to track down possible suspects since similar, unconscious patterns tend to appear in one’s writing as well.
