We are a group of researchers investigating human factors and cogntiive issues in forensic identification and their solutions. This applied area of cognitive forensics bring together a number of domains in human information processing in which we specialize within cognitive psychology. These domains include pattern recognition, mental representations, decision making, expertise, visual cognition, and knowledge acquisition. These areas all converge together in the applied domains of biometrics and the criminal justice system. Other areas of interest to us which are vital for biometric and forensic applications are the use and integration of technology and selection & training of examiners; including issues of confirmation & other cognitive biases, and optimizing decision making (for more information, please also see the pages dedicated to decision making and to cognition & technology).
We have taken our expertise in these areas and our understanding of human performance & cognition and have applied them to real world issues (not only in forensic science, but in many other expert domains, such as medicine, frontline policing, and US Air Force pilots).
Through Cognitive Consultants International (CCI-HQ) we have provided training and consultancy to forensic examiners on how to deal with and minimize confirmation and other cognitive biases (e.g., to police forces and national forensic institutes in the Netherland and Australia, as well as to police forces in the US and the UK, such as the London Metrapolitan Police, Greater Manchester Police, NYPD, LAPD, and the FBI). We have also provided expert reports and testimony on these issues to the courts (e.g., in the case of R v Shahiriar Firouzian, and the Levi Bellfield serial killer case in the Central Criminal Court at the Old Bailey in London), and to legislators (e.g., MD Senate hearings on Bill 404 regarding Criminal Law – Death Penalty – Evidence). We provided consultancy to the UK Passport and Identity Services on reducing fraud detection through facial recognition. Dr Itiel Dror is an Associate Editor and on the Board of Editors of a number of scientific journals, such as Science & Justice, Forensic Science Policy & Management, and Pragmatics & Cognition.His research has been cited throughout the National Academy of Sciences report on Forensic Science (2009), the Fingerprint Enquiry Report, and in dozens of court cases (e.g., by the Supreme Judicial Court of Massachusetts, in the case of Commonwealth vs. Gambora, 2010; by the Court of Appeal in the UK, in the cases of R v Dlugosz, Pickering, and MDS, 2013).
Dr. Itiel Dror has received the 2014 ABP (Association for Business Psychology) Annual Award for 'Excellence in Training' for his work in improving decision making and reducing bias in forensic science, and is the Chair of the Forensic Human Factors Committee of the US Department of Justice (DoJ) & National Institute of Standards and Technology (NIST). Dr Dror is also a member of the AAAS (The American Association for the Advancement of Science) Advisory Committee on Forensic Science Assessment (a project in which the AAAS will conduct an analysis of the underlying scientific bases for the forensic tools and methods currently used in the criminal justice system).
