Do psychopathic individuals possess a misaligned moral compass? A meta-analytic examination of psychopathy’s relations with moral judgment.

Abstract

Psychopathic individuals are often characterized as lacking a moral sense. Although this hypothesis has received ample experimental attention over the past decade, findings have been inconsistent. To elucidate the relationship between psychopathy and abnormal moral judgment, we conducted a meta-analysis of the research on psychopathy and morality-related variables (k = 23, N = 4376). A random effects model indicated a small but statistically significant relation between psychopathy and moral decision-making (rw = .16) and moral reasoning (r = .10) tasks. These results reveal at best modest support for the common perception that psychopathic individuals fail to understand moral principles. A secondary meta-analysis (k = 9, N = 4294) of the growing body of literature on the relationship between psychopathy and moral reasoning on moral foundations measures provides preliminary evidence that psychopathic individuals may possess a differential set of "moral taste buds" than less psychopathic individuals. We discuss the implications of the results from both meta-analyses for models of the etiology of psychopathy and the criminal responsibility of psychopathic individuals. (PsycINFO Database Record

Personality predictors of creative achievement and lawbreaking behavior

“…Both Eysenck (1995) and Galang (2010) believed that creativity and disagreeable behavior are not causally connected but are products of a common underlying personality process. The fact that trait psychopathy does not seem to be strongly related to any particular deficit in moral reasoning (Marshall et al 2017;Marshall et al 2018) is perfectly consistent with the claim that creative individuals display good moral judgment as well as with the saying that in spite of their capacity for moral reasoning, creative people are prone to engage in morally dubious behavior and lawbreaking. In addition, since our data concerns creative achievement, some of these critiques might not be directly relevant, since most of the contrary evidence and arguments seems to focus either on creativity tasks (e.g., Liu et al 2014), Blittle-c^creativity (Niepel et al 2015), or with anecdotal examples (Shen et al 2017).…”

Internet trolling and everyday sadism: Parallel effects on pain perception and moral judgment

“…That level would better implicate moral culpability. To this end, we drew on emerging evidence that antisocial traits such as sadism (Trémolière & Djeriouat, 2016) and psychopathy (Marshall, Watts, & Lilienfeld, 2018) are accompanied by deficient moral judgment. Psychological rationalization may help explain how otherwise average people can reconcile cruel behavior with a positive self-view.…”

Lay Theories and Attitudes About Psychopathy

“…The authors' second meta-analysis was on the relationship between moral reasoning and psychopathy using moral foundations measures, and it revealed preliminary evidence that psychopathic individuals may have a differential set of "moral taste buds" than less psychopathic people. The authors suggest that their findings provide evidence against the idea that psychopathic individuals possess a distinct and overarching moral deficit (Marshall et al, 2016), a belief often held by laypeople . Instead, they suggest that psychopathic individuals may display subtle differences in moral decision-making and reasoning inclinations (Marshall et al, 2016).…”
