Brain Scans As Evidence: Truths, Proofs, Lies, And Lessons, Owen D. Jones, Francis X. Shen Apr 2019

Brain Scans As Evidence: Truths, Proofs, Lies, And Lessons, Owen D. Jones, Francis X. Shen

Owen Jones

This contribution to the Brain Sciences in the Courtroom Symposium identifies and discusses issues important to admissibility determinations when courts confront brain-scan evidence. Through the vehicle of the landmark 2010 federal criminal trial U.S. v. Semrau (which considered, for the first time, the admissibility of brain scans for lie detection purposes) this article highlights critical evidentiary issues involving: 1) experimental design; 2) ecological and external validity; 3) subject compliance with researcher instructions; 4) false positives; and 5) drawing inferences about individuals from group data. The article’s lessons are broadly applicable to the new wave of neurolaw cases now being seen …

This article, part of a symposium on the opinion of the Arizona Supreme Court in Logerquist v. McVey, questions that court’s rationales for refusing to apply heightened scrutiny to psychiatric testimony about the retrieval of repressed memories. It also challenges the court’s use of a “personal observations” exception to the heightened scrutiny standard of Frye v. United States. It proposes that a better solution to problems of scientific and expert evidence would be to adopt a sliding scale that attends to the use to which the evidence is put and the degree to which it has been shown to be …
