The most difficult part of personality assessment involves determining the reliability of the information a person reports about himself. Today, psychologists, criminologists, and intelligence officers already have a fairly wide arsenal of tools to solve this problem: from non-contact methods of non-verbal personality assessment to testing with a contact polygraph (lie detector). This book discusses psychophysiological and psychological assessment methods, such as handwriting analysis, associative-motor techniques, and social surveys. Particular attention is paid to working with a “lie detector” (polygraph). The book may be of interest to HR specialists and all those interested in psychophysiological methods of obtaining reliable information.
