Mitigating factors
On the other side, the defense expert also faces significant challenges, though the tools are different. Contrary to the prosecuting expert who loads an arsenal of subjective assessment tools, the defense expert will point to childhood trauma and mental illness as extenuating explanations for a crime. Having suffered abuse as a child is advanced to justify someone’s subsequent violence. This problem is reflected in the diagnosis of posttraumatic stress disorder (PTSD). An unscrupulous expert may simply allow an evaluee to endorse symptoms without clinical correlates or rigorous validation to advance this narrative.
For example, psychiatrists commonly ascribe the DSM criteria A for PTSD, “directly experiencing the traumatic event(s),” to a smaller slight in life. Some experts suggest that a medical diagnosis, even if not life-threatening but perceived as such, could warrant the diagnosis.10 This would expand our understanding of trauma and its consequences significantly. Yet already, a survey of Detroit area residents in 1998 found that 89.6% of the interviewees reported having experienced a significant trauma and that the average number of traumatic experiences was 4.8.11 The meaning of a diagnosis that can be applied to almost 90% of a population has unclear usefulness, especially if meant to diminish guilt and responsibility.
More recently, citing Adverse Childhood Experiences (ACEs) has been a common method of supporting mitigating evaluations. Using the ACEs questionnaires, researchers have supported the idea that social programs are a key player in an improved criminal justice system. The ACEs study identified 10 forms of childhood trauma in 17,000 patients, including abuse, neglect, abandonment, household dysfunction, and exposure to violence, that were strongly associated with negative psychological outcomes, engagement in high-risk behaviors, significant medical consequences, and even early death.12 However, similarly to past trauma, the prevalence of ACEs in the forensic population is the norm, not the exception.
Additional thoughts
Of particular concern is when diagnostic criteria intersect or seemingly contradict one another. For example, acts such as an outburst of anger may be interpreted by one evaluator as a sign of deviance, irritability, or recklessness – and meeting antisocial personality disorder criteria. Whereas another evaluator may interpret the same incident as hypervigilance, exaggerated startle response, or self-destructive behavior in PTSD.
An incident of not assisting someone in need may be interpreted as lack of remorse and glibness from antisocial characteristics or avoidance and detachment from others as a reaction to past trauma. Flashbacks from trauma can be interpreted by some as violent fantasies. Even the experience of trauma can be viewed as a risk factor for future violence. In some ways, our perspectives are influenced by our examination of someone’s history through the lens of sociopathy or empathy.
In summary
Psychiatry is entrusted by courts to comment on negative and mitigating factors. Negative factors hinge in part on our subjective impression of sociopathy, and mitigating factors hinge, in part, on our empathy for a defendant’s trauma. Psychiatry should recognize the limitations of both sides and humble itself in providing balanced evaluations to courts.
