Tortini
Tortini, published by Nathan A. Schachtman, focuses on the intersection of scientific evidence and legal standards in tort litigation. The blog critically examines issues such as causation analysis in toxic torts, the reliability of expert testimony, and the influence of biases in scientific research related to litigation. It covers topics including the evaluation of epidemiological studies, the role of regulatory science, conflicts of interest in expert opinions, and the application of legal standards like Rule 702 and Daubert in court. The blog also discusses controversies around pharmaceutical safety, environmental toxicants, and the challenges of presenting scientific evidence in judicial proceedings.

Prada – Fashionable, But Unreliable Review on Acetaminophen and Autism
Back in the first week of this month, I posted about a paper (Prada 2025),[1] which featured a so-called navigation-guide systematic review of the scientific evidence on the issue whether pregnant women’s ingestion of acetaminophen causes their children to…
Specific Causation – The Process of Elimination
