The Foundations of the Comparison Forensic Sciences: Report of the President's Council of Advisors on Science and Technology

Research output: Contribution to journalArticleOtherpeer-review


In September 2016, the President’s Council of Advisors on Science and
Technology (PCAST) in the United States published its report to the President
entitled Forensic Science in Criminal Courts: Ensuring Scientific Validity of
Feature-Comparison Methods. The need for this report arose out of the highly
critical 2009 National Research Council report on the state of forensic
sciences in the United States. The report had noted that there were particular
problems in feature-comparison disciplines where the science underpinning
the validity of the discipline was poor. The PCAST report has developed the
National Research Council’s thinking further. It looked at the foundational
validity of a number of forensic disciplines, including, for example, bite mark
interpretation in forensic odontology. PCAST concluded that bite mark analysis
does not meet the scientific standards for foundational validity. In addition, it felt that the prospects of developing bite mark analysis into a scientifically valid
method were poor, and they advised against government investment in
research to try to establish such validity.The principles discussed in this report,
focused as they are on forensic science, will need to be digested by forensic
medicine. Forensic medicine will be increasingly called upon to justify the
validity of the various areas in which its practitioners provide expert evidence.
