Challenging a flexible neuropsychological battery under Kelly/Frye: a case study.

The ability of the flexible neuropsychological battery approach to withstand a challenge under California's evidentiary standard, Kelly/Frye, was tested in an actual trial. Despite repeating many criticisms offered by the literature (e.g., no malingering measures, unknown accuracy rates, ignoring statistical limitations, not using age norms), the battery was allowed in "for the weight of the evidence," rather than being excluded as unreliable.
