This guide is for use by attorneys when questioning a witness named by opposing counsel as their DV expert. A strategy and deposition questions are provided. Additionally, a non-transferrable limited license is provided to original purchasing attorneys to use the Empirical Capability Assessment Test, Modified For Attorneys (ECAT-MFA), which is a set of questions to be asked in deposition. Responses can be scored by Dr. Nelson who will rank the witness as demonstrating adequate empirical skills, demonstrating some empirical skills or demonstrating a lack of empirical skill. Those with limited or no empirical skills are at high risk for testifying to false and disproven "facts" about DV because they lack the ability to parse well done empirical research from badly done and untrustworthy "science." The responses of DV "experts" with little to no empirical skills may help support a motion to disqualify. Additionally, responses will reveal the extent to which an "expert" testifies to empirical facts or to dogma and belief. A sample report is included. This is a one of a kind resource.
