The findings of all of these evaluations could then be used to paint a picture that sheds light on whether the insanity plea in question is potentially or verifiably legitimate or if it seems to be a ploy to get around the charges in play. Some notable findings of the study reviewed for this discussion response include the fact that there was some disparate responses among the study subjects but it did not seem to be based on the fact that some of the people involved were psychologists while others were psychiatrists (Gowensmith, Murrie & Boccaccini, 2013).

Forensic psychologists should also take note that the study found that of all of the cases where an insanity defense was actually used, only 35.4% of the people in question (out of around 450 cases) were found insane while 58.6% were found sane. Of those 450 or so cases, there was unanimous agreement amongst all relevant forensic psychologists, psychiatrists and so forth just more than half the time. In the other 45% or so of cases, there was always at least one detractor from the larger group...

As such, this would tell forensic psychologists that the science is not exact and multiple professionals looking at the same case might find differently even after reviewing the same facts (Gowensmith, Murrie & Boccaccini, 2013).
