Identify what type of testing would need to be done to ensure that the assertion that “no two fingerprints are alike” is true? Examine whether or not this type of testing is feasible and why or why not. Analyze what role cognitive bias might play in influencing the forensic lab results of tests in areas such as fingerprint identification, firearms identification, bite mark identification, or the “smell of death” technique described in the Frontline film. There is much criticism that techniques used in fingerprint identification and other types of forensic identification described in the NAS report (Chapter 5) are inherently unscientific because there have been no validation studies. Without validation studies that establish known error rates, these methods cannot be said to be scientifically sound. Recommend whether or not to use commonly accepted scientific techniques that have not been scientifically validated and supports these recommendations with research materials. Suggest at least one intervention to overcome the effects of cognitive bias that may influence a forensic examiner’s identification decision. Analyze the type of training and credentials forensic examiners should have in order to work in a forensics lab. Provide recommendations for training and credentialing forensic examiners to ensure that they are adequately trained.
