Vos PCAST Article

Vos PCAST Article

Eric Ray and Glenn Langenburg discuss last year’s article, Using the PCAST Report to Exclude, Limit, or Minimize Experts by Eric Alexander Vos published in Criminal Justice. We note the extreme bias of the article to exploit the emotions of the judge and jury instead of logic, reason, or data, and we find the serious flaws in many aspects of the paper.

Koehler Error Rate Article

Koehler Error Rate Article

Glenn Langenburg and Eric Ray follow up from last week’s discussion of Glenn’s recent Daubert hearing with a 2016 article from Jonathan Koehler entitled, Intuitive Error Rate Estimates for the Forensic Sciences. As Glenn suspected, the findings of this article are suspiciously close to the center of the group of choices that participants were presented with. Although there are some larger themes that are interesting, the exact values of the error rate estimates from potential jurors do not match personal experience or even some of the cited prior works.
