This paper supplements our Commentary on “Three-Way ROCs for Forensic Decision Making” by Nicholas Scurich and Richard S. John (in: Statistics and Public Policy). We reply to allegations made by Nicholas Scurich and Richard S. John in their rejoinder "On Coping in a Non-Binary World: Rejoinder to Biedermann and Kotsoglou". These allegations do not carry sufficient intellectual weight to warrant discussion in a published response. However, they are serious insofar as they misquote and misinterpret our Commentary, contain demonstrably false assertions, and thus amount to an attempt to mislead the scientific and legal communities. In this paper, we provide the context and background at the origin of this debate and examine each of Scurich and John’s allegations.
