The Association for Psychological Science published a review by Tess Neal, Christopher Slobogin, Michael Saks, David Faigman, and Kurt Geisinger on the psychological assessment tools used by forensic psychologists. The study found 67% are generally accepted in the field and only about 40% have generally favorable reviews of their psychometric and technical properties.
The study also found that legal challenges to the admission of this evidence are infrequent. Legal challenges occurred in only 5.1% of cases in the sample. When challenges were raised, they succeeded about a third of the time. Challenges to the most scientifically suspect tools are almost nonexistent.
