Since the 18th century, one of the key features of diagnosed psychopaths has been “moral colorblindness” or an inability to form moral judgments. However, attempts at experimentally verifying this moral incapacity have been largely unsuccessful. After reviewing the centrality of “moral colorblindness” to the study and diagnosis of psychopathy, I argue that the reason that researchers have been unable to verify that diagnosed psychopaths have an inability to make moral judgments is because their research is premised on the assumption that (...) there is a specific moral faculty of the brain, or specific “moral” emotions, and that this faculty or set of emotions can become “impaired”. I review recent research and argue that we have good reason to think that there is no such distinct capacity for moral judgment, and that, as a result, it is impossible for someone’s “moral judgment faculty” to become selectively disabled. I then discuss the implications of such a position on psychopathy research, the coherence of the disorder, and the moral responsibility of psychopaths. (shrink)

The psychological literature now differentiates between two types of psychopath:successful (with little or no criminal record) and unsuccessful (with a criminal record). Recent research indicates that earlier findings of reduced autonomic activity, reduced prefrontal grey matter, and compromised executive activity may only be true of unsuccessful psychopaths. In contrast, successful psychopaths actually show autonomic and executive function that exceeds that of normals, while having no difference in prefrontal volume from normals. We argue that many successful psychopaths are legally responsible for (...) their actions, as they have the executive capacity to choose not to harm (and thus are legally rational). However, many unsuccessful psychopaths have a lack of executive function that should at least partially excuse them from criminal culpability. Although a successful psychopath's increased executive function may occur in conflict with, rather than in consonance with their increased autonomic activity - producing a cognitive style characterized by self deception and articulate-sounding, but unsound reasoning - they may be capable of recognizing and correcting their lack of autonomic data, and thus can be held responsible.

De Re Significance accounts of moral appraisal consider an agent’s responsiveness to a particular kind of reason, normative moral reasons de re, to be of central significance for moral appraisal. Here, I argue that such accounts find it difficult to accommodate some neuroatypical agents. I offer an alternative account of how an agent’s responsiveness to normative moral reasons affects moral appraisal – the Reasonable Expectations Account. According to this account, what is significant for appraisal is not the content of the (...) reasons an agent is responsive to, but rather whether she is responsive to the reasons it is reasonable to expect her to be responsive to, irrespective of their content. I argue that this account does a better job of dealing with neuroatypical agents, while agreeing with the De Re Significance accounts on more ordinary cases. (shrink)

In popular culture psychopaths are inaccurately portrayed as serial killers or homicidal maniacs. Most real-world psychopaths are neither killers nor maniacs. Psychologists currently understand psychopathy as an affective disorder that leads to repeated criminal and antisocial behavior. Counter to this prevailing view, I claim that psychopathy is not necessarily linked with criminal behavior. Successful psychopaths, an intriguing new category of psychopathic agent, support this conception of psychopathy. I then consider reactive attitude theories of moral responsibility. Within this tradition, psychopaths are (...) thought to be blameless as a result of their pronounced affective deficits. Psychopaths are considered morally blind because they lack the moral emotions that make us sensitive to moral reasons. I argue that, even if they are morally blind, psychopaths remain open to forms of blame stemming from non-moral reactive attitudes. These reactive attitudes remain appropriate because psychopaths can express hateful, disgusting, or contemptible non-moral values in their judgments. (shrink)

I argue that psychopathy undermines three common assumptions typically invoked in favor of moderate reasons responsive theories of moral responsibility. First, I propose a theory of psychopathic agency and claim that psychopathic agency suggests that the systems underlying receptivity to reason bifurcate into at least two sub-systems of receptivity. Next, I claim that the bifurcation of systems for receptivity suggests that reactivity is not “all of a piece” but that it too decomposes into at least two subsystems. Lastly, I argue (...) that prior attempts by Fischer and Ravizza to address these concerns contain an appeal to internalism. Since Fischer and Ravizza want their theory to remain agnostic about the nature of reasons for action, this appeal to internalism is problematic for their view. I close by suggesting that if we are to make sense of when and why psychopaths are responsible then a mechanism-based theory of responsibility must be able to explain how different systems of receptivity and reactivity come together to constitute a single mechanism that grounds responsibility ascriptions for action and they must do so without tacitly appealing to implausible forms of internalism about reasons for action.

Many believe that there is at least some asymmetry between the extent to which moral and non-moral ignorance excuse. I argue that the exculpatory force of moral ignorance—or lack thereof—poses a thus far overlooked challenge to moral realism. I show, firstly, that if there were any mind-independent moral truths, we would not expect there to be an asymmetry in exculpatory force between moral and ordinary ignorance at all. I then consider several attempts the realist might make to deny or accommodate (...) this datum, and show why none of them work. (shrink)

Reactive theories of responsibility see moral accountability as grounded on the capacity for feeling reactive-attitudes. I respond to a recent argument gaining ground in this tradition that excludes psychopaths from accountability. The argument relies on what Paul Russell has called the 'subjectivity requirement'. On this view, the capacity to feel and direct reactive-attitudes at oneself is a necessary condition for responsibility. I argue that even if moral attitudes like guilt are impossible for psychopaths to deploy, that psychopaths, especially the "successful" (...) and "secondary" subtypes of psychopathy, can satisfy the subjectivity requirement with regard to shame. I appeal to evidence that embarrassment and shame are grounded on the same affective process and data that psychopathic judgments about embarrassment are neurotypical. If I am right, then psychopaths ought to be open to shame-based forms of accountability including shame punishments. I conclude by considering why psychopaths rarely self-report shame. I argue that lacking a capacity to see oneself as flawed is a different sort of failure than lacking the capacity to feel. (shrink)

Sometimes we make mistakes, even when we try to do our best. When those mistakes are about normative matters, such as what is required, this leads to a puzzle. This puzzle arises from the possibility of misleading evidence about what rationality requires. I argue that the best way to solve this puzzle is to distinguish between two kinds of evaluation: requirement and appraisal. The strategy I defend connects three distinct debates in epistemology, ethics, and normativity: the debate over how our (...) theories of epistemic rationality should accommodate misleading evidence, the debate over the relationship between complying with requirements and deserving particular appraisals, and the debate over whether normative ignorance can excuse. Part 1 shows how three apparently plausible claims about epistemic rationality generate a puzzle when agents have misleading evidence about what rationality requires. Part 2 solves this puzzle by distinguishing between evaluations of requirement and appraisal and rejecting the idea that one is required to conform to the Enkratic Principle. I argue instead that complying with the Enkratic Principle provides defeasible evidence that the agent should be positively appraised. One of the consequences of this solution is that false normative beliefs can sometimes excuse agents from negative appraisal they would otherwise deserve for violating requirements. Part 3 defends the view that false normative belief can sometimes excuse against the rival views that false normative belief always excuses, and that false normative belief never excuses. I argue that false normative belief can sometimes excuse violations of requirements, when it is the case that the agent has done what it is reasonable to expect of her. (shrink)

Researchers who argue that moral judgment is based on emotions (`emotion-backers') and those who believe that it is based on reasoning and deliberation (`reasoning-backers') have both struggled to account for the notorious moral deviance of incarcerated psychopaths. Emotion-backers, such as Jonathan Haidt, focus on psychopaths' lack of a affect,or defciencies in particular emotions, such as sympathy. Reasoning-backers, such as Lawrence Kohlberg, focus instead on psychopaths' de cient reasoning. Both accounts offer separate descriptions of what goes wrong in the disorder, but (...) neither can fully explain psychopathic moral deviance. The moral account that I built, bridges these accounts in an attempt to better and more fully describe the empirical data available on psychopathic moral judgment. I argue that their judgment is best explained with a dual-process account of moral judgment that incorporates a large system of moral emotions as well as integrates multiple bases of morality, such as concerns of fairness, harm, and purity. It is only by focusing on both the reasoning and emotional de cits in psychopaths that we can begin to understand psychopaths' use of utilitarian reasoning, general population psychopaths, and psychopaths' di erential presence in the prison popu- lation. All of these issues are best described using a dual-process account of moral judgment that incorporates a larger system of moral emotions than other accounts of morality as well as a pluralistic conception of moral foundations. I used psychopaths because their moral deviance can teach us about morality more broadly. By understanding the cognitive processes implicated in the moral judgment of psychopaths, I better explain how moral judgment works in the general population more broadly. My account of moral judgment has both theoretical and practical applications. Theoretically, it o ers a new dual-process paradigm for describing moral behaviour which bridges reasoning-based and emotion-based accounts. This description can explain both the moral deviance of psychopaths as well as, more broadly, moral judgment in non-psychopaths. Additionally, my theory challenges accounts of moral emotion that narrowly focus on speci c emotions, such as guilt or empathy. It in- stead integrates all emotions, including disgust, fear, and sympathy, and links speci c emotions to moral judgments. Practically, my paradigm of moral judgment encourages the development of new moral judgment measurements such as new self-report questionnaires of moral reasoning. According to my research, in order for these tools to accurately measure morality, they need to account for both emotion-based and reasoning-based judgments. (shrink)
