    Are Psychopathy Checklist (PCL) Psychopaths Dangerous, Untreatable, and Without Conscience? A Systematic Review of the Empirical Evidence.Rasmus Rosenberg Larsen, Jarkko Jalava & Stephanie Griffiths - 2020 - Psychology, Public Policy and Law 26 (3):297–311.
    The Hare Psychopathy Checklist (PCL; Hare, Neumann, & Mokros 2018) scales are among the most widely used forensic assessment tools. Their perceived utility rests partly on their ability to assess stable personality traits indicative of a lack of conscience, which then facilitates behavioral predictions useful in forensic decisions. In this systematic review, we evaluate the empirical evidence behind 3 fundamental justifications for using the PCL scales in forensics, namely, that they are empirically predictive of (1) criminal behavior, (2) treatment outcomes, (...)

  2. Is the Psychopathic Brain an Artifact of Coding Bias? A Systematic Review.Jarkko Jalava, Stephanie Griffiths, Rasmus Rosenberg Larsen & B. Emma Alcott - 2021 - Frontiers in Psychology 12.
    Questionable research practices are a well-recognized problem in psychology. Coding bias, or the tendency of review studies to disproportionately cite positive findings from original research, has received comparatively little attention. Coding bias is more likely to occur when original research, such as neuroimaging, includes large numbers of effects, and is most concerning in applied contexts. We evaluated coding bias in reviews of structural magnetic resonance imaging studies of PCL-R psychopathy. We used PRISMA guidelines to locate all relevant original sMRI studies (...)

    Philosophers On Psychopaths: A Cautionary Tale in Interdisciplinarity.Jarkko Jalava & Stephanie Griffiths - 2017 - Philosophy, Psychiatry, and Psychology 24 (1):1-12.
    Philosophers typically rely on empirical data when they comment on psychopaths’ moral responsibility. Many argue that psychopaths, as per the data, suffer from significant impairments in the precursors of moral reasoning and behavior, and therefore they should not be held morally responsible for their actions. However, careful analysis of these studies shows that this view is mistaken. We discuss how several philosophers— perhaps following the lead of social scientists—have systematically misinterpreted or simplified psychological data to support their conclusions about psychopaths’ (...)
