Psychopathy is often used to settle disputes about the nature of moral judgement. The Trolley Problem is a familiar scenario in which psychopathy is used as a test case. Where a convergence in response to the Trolley Problem is registered between psychopathic subjects and non-psychopathic (normal) subjects, it is assumed that this convergence indicates that the capacity for making moral judgments is unimpaired in psychopathy. This in turn is taken to have implications for the dispute between motivation internalists and motivation externalists, for instance. In what follows, we want to do two things: firstly, we set out to question the assumption that convergence is informative of the capacity for moral judgement in psychopathy. Next, we consider a distinct feature of psychopathy which we think provides strong grounds for holding that the capacity for moral judgement is seriously impaired in psychopathic subjects. The feature in question is the psychopathic subject's inability to make sincere apologies. Our central claim will be this: convergence in response to Trolley Problems doesn't tell us very much about the psychopathic subject's capacity to make moral judgements, but his inability to make sincere apologies does provide us with strong grounds for holding that this capacity is seriously impaired in psychopathy.Psychopathy: what apology making tells us about moral agency
