Is there any research indicating whether certain personality types have an easier time passing polygraph tests?
There is no research to indicate that the effects of personality variables are consistent for the various polygraph techniques. Personality is not an explicit component in any of the theories of polygraph, and it is not viewed as an important factor by field practitioners, which may explain why it has rarely been the focus of investigation in polygraph research. Some researchers have reported on the influence of demographic and psychological variables in their polygraph validity studies. Refer to attached Table for a summary of those effects.
