Abstract

The psychological and neurobiological processes underlying moral judgement have been the focus of many recent empirical studies. Of central interest is whether emotions play a causal role in moral judgement, and, in parallel, how emotion-related areas of the brain contribute to moral judgement. Here we show that six patients with focal bilateral damage to the ventromedial prefrontal cortex (VMPC), a brain region necessary for the normal generation of emotions and, in particular, social emotions, produce an abnormally 'utilitarian' pattern of judgements on moral dilemmas that pit compelling considerations of aggregate welfare against highly emotionally aversive behaviours (for example, having to sacrifice one person's life to save a number of other lives). In contrast, the VMPC patients' judgements were normal in other classes of moral dilemmas. These findings indicate that, for a selective set of moral dilemmas, the VMPC is critical for normal judgements of right and wrong. The findings support a necessary role for emotion in the generation of those judgements.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Damage to MPFC regions causes disturbances in moral behavior and moral reasoning.

    “Convergent evidence from neuropsy- chological studies suggests that damage to these regions causes disturbances in moral behavior and moral reasoning (33–35).”
  • Ventromedial patients more often than controls choose to push an innocent man to death to save five others.

    “they would decide to push an innocent man to death on the tracks of a runaway trolley to save five other individuals more often than controls (Ciaramelli et al., 2007;Koenigs et al., 2007).”

    From Affective Cognition and its Disruption in Mood Disorders (2011) · cites this paper as Koenigs et al., 2007

  • The RTPJ appears to be strongly connected to other regions implicated in mental state attribution and moral cognition, such as the left TPJ, precuneus, and medial prefrontal cortex.

    “The RTPJ appears to be strongly connected to other regions implicated in mental state attribution (4, 13, 28–30) and moral cognition (16, 19, 31–34), such as the left TPJ, precuneus, and medial prefrontal cortex.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
