Abstract: Clinical theory is skeptical of individuals’ ability to recognize the presence, severity, and impact of clinical symptoms and pathological traits (Oltmanns & Powers, 2012); however, empirical work has found moderate self-other convergence for reports of pathological traits and for Antagonism-related personality disorder (PD) constructs (i.e., psychopathy, narcissism, and Machiavellianism), which are characterized by low insight. Nevertheless, empirical examinations of insight into perceptions of impairment is scant. Thus, the present study sought to examine individuals’ insight regarding pathological traits and related impairment in two samples. In Sample 1, more psychopathic, narcissistic, and Machiavellian individuals reported higher levels of pathological traits and were aware of related impairment. In Sample 2, individuals reported higher levels of pathological traits and, albeit to a lesser degree, more Antagonism-related impairment. Thus, more psychopathic, narcissistic, and Machiavellian individuals possess a reasonable degree of insight into their trait levels and associated impairment.
