The art and science of detecting deception has always been a fascinating area for me, especially being a veteran of law enforcement and current trainer in interview and interrogation techniques, statement analysis, detecting deception, and credibility assessment.
As a professional interviewer, it is important to stay on top of BOTH...the art and science...of detecting deception. One can be very skilled at the art and interpersonal level of conducting interviews and interrogations, but if they use tactics and employ techniques which are unethical, ineffective or have been proven to be inaccurate as a method of distinguishing between truthfulness and deception, that can have disastrous results for their investigations. The same is true for science. If you conduct experiments, test college kids and write your thesis on effective methods of identifying when someone is lying or telling the truth, but is does not get into the hands of the interviewers conducting critical, high-stakes interviews, that does not help improve the interview and interrogation process either.
To help keep you on the cutting edge, check out the information from the 13th Conference of the European Chapter of the Association of Computational Linguistics during the Workshop on Computational Approaches to Detecting Deception held earlier this year. Don't let the fancy name scare you off...click the link below for the information presented at this conference.
