Prof. Galit Nahari
Principal Investigator

Prof. Galit Nahari is the head of the Department of Criminology at Bar-Ilan University, Israel, and the editor of Legal and Criminological Psychology. Her research spans over a variety of topics in deception, applied memory, investigative interviewing and decision-making. As part of it, she develops interrogation and lie-detection methods (a prime example is the Verifiability Approach), examines their validity and suitability in different contexts, and their vulnerability to judgmental biases. A major part of her research further focuses on the cognitive processes underlies credibility and veracity assessments, as well as on individual differences which impact these assessments. She places a high emphasis on ecological validity and relevancy to the “real world”; thus, she works closely with practitioners, promoting fruitful academia-field cooperation in high education, research and training. She advises, lectures and conducts research and training workshops on verbal lie detection nationally and internationally.
