What new developments do we have to offer in this third edition of the book? The conceptual and empirical underpinnings of the Forensic Distortion Analysis (FDA-5) model continue to be explored, refined, and expanded. Virtually every chapter has been updated with new studies and updated, empirically based, research. New chapters have been added to amplify methodological rigor in forensic cases involving child abuse and neglect, and a clearer idea on evolving trends and advances in deception analysis. New information has been added to include discussions of terrorism by individuals and small groups, an expanded commentary on deception and American wars, and the role of deception in the media, politics, finance, and business. In the utilization of principle-driven, ethically consistent, deception-related information and procedures, however, this book steadfastly pursues quality forensic evaluation of individual persons, consultation, training, and research, and proffering opinions as an expert in the criminal or civil court.
