  1. Responsible Brains: Neuroscience, Law, and Human Culpability.William Hirstein, Katrina L. Sifferd & Tyler K. Fagan - 2018 - New York, NY, USA: MIT Press.
    [This download includes the table of contents and chapter 1.] -/- When we praise, blame, punish, or reward people for their actions, we are holding them responsible for what they have done. Common sense tells us that what makes human beings responsible has to do with their minds and, in particular, the relationship between their minds and their actions. Yet the empirical connection is not necessarily obvious. The “guilty mind” is a core concept of criminal law, but if a defendant (...)

    Are Psychopaths Legally Insane?Anneli Jefferson & Katrina Sifferd - 2018 - European Journal of Analytic Philosophy 14 (1):79-96.
    The question of whether psychopaths are criminally and morally responsible has generated significant controversy in the literature. In this paper, we discuss what relevance a psychopathy diagnosis has for criminal responsibility. It has been argued that figuring out whether psychopathy is a mental illness is of fundamental importance, because it is a precondition for psychopaths’ eligibility to be excused via the legal insanity defense. But even if psychopathy counts as a mental illness, this alone is not sufficient to show the (...)

  3. On the Criminal Culpability of Successful and Unsucessful Psychopaths.Katrina L. Sifferd & William Hirstein - 2013 - Neuroethics 6 (1):129-140.
    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 (...)

    When laws or legal principles mention mental states such as intentions to form a contract, knowledge of risk, or purposely causing a death, what parts of the brain are they speaking about? We argue here that these principles are tacitly directed at our prefrontal executive processes. Our current best theories of consciousness portray it as a workspace in which executive processes operate, but what is important to the law is what is done with the workspace content rather than the content (...)

    How Is Criminal Punishment Forward-Looking?Katrina L. Sifferd - 2021 - The Monist 104 (4):540-553.
    Forward-looking aims tend to play a much less significant role than retribution in justifying criminal punishment, especially in common law systems. In this paper I attempt to reinvigorate the idea that there are important forward-looking justifications for criminal law and punishment by looking to social theories of responsibility. I argue that the criminal law may be justified at the institutional level because it is a part of larger responsibility practices that have the effect of bolstering our reasons-responsiveness by making us (...)

  6. Translating Scientific Evidence Into the Language of the ‘Folk’: Executive Function as Capacity-Responsibility.Katrina L. Sifferd - 2013 - In Nicole A. Vincent (ed.), Legal Responsibility and Neuroscience. Oxford University Press.
    There are legitimate worries about gaps between scientific evidence of brain states and function (for example, as evidenced by fMRI data) and legal criteria for determining criminal culpability. In this paper I argue that behavioral evidence of capacity, motive and intent appears easier for judges and juries to use for purposes of determining criminal liability because such evidence triggers the application of commonsense psychological (CSP) concepts that guide and structure criminal responsibility. In contrast, scientific evidence of neurological processes and function (...)

    Author’s Reply: Negligence and Normative Import.Katrina L. Sifferd & Tyler K. Fagan - 2022 - Criminal Law and Philosophy 22 (August):1-19.
    In this paper we attempt to reply to the thoughtful comments made on our book, Responsible Brains, by a stellar group of scholars. Our reply focuses on two topics discussed in the commenting papers: frst, the issue of responsibility for negligent behavior; and second, the broad claim that facts about brain function are normatively inert. In response to worries that our theory lacks normative implications, we will concentrate on an area where our theory has clear relevance to law and legal (...)

    In Defense of the Use of Commonsense Psychology in the Criminal Law.Katrina L. Sifferd - 2006 - Law and Philosophy 25 (6):571 - 612.
    The criminal law depends upon 'commonsense' or 'folk' psychology, a seemingly innate theory used by all normal human beings as a means to understand and predict other humans' behavior. This paper discusses two major types of arguments that commonsense psychology is not a true theory of human behavior, and thus should be eliminated and replaced. The paper argues that eliminitivist projects fail to provide evidence that commonsense psychology is a false theory, and argues that there is no need to seek (...)

    Do Rape Cases Sit in a Moral Blindspot?Katrina L. Sifferd - forthcoming - In Samuel Murray & Paul Henne (eds.), Advances in Experimental Philosophy of Action. London, UK:
    Empirical research has distinguished moral judgments that focus on an act and the actor’s intention or mental states, and those that focus on results of an action and then seek a causal actor. Studies indicate these two types of judgments may result from a “dual-process system” of moral judgment (Cushman 2008, Kneer and Machery 2019). Results-oriented judgements may be subject to the problem of resultant moral luck because different results can arise from the same action and intention. While some argue (...)

Sifferd - 2018 - In Bebhinn Donnelly Lazarov (ed.), Neurolaw and Responsibility for Action: Concepts, Crimes, and Courts. Cambridge: Cambridge University Press. pp. 71-103.
    This chapter will argue that the criminal law is most compatible with a specific theory regarding the mind/body relationship: non-eliminative reductionism. Criminal responsibility rests upon mental causation: a defendant is found criminally responsible for an act where she possesses certain culpable mental states (mens rea under the law) that are causally related to criminal harm. If we assume the widely accepted position of ontological physicalism, which holds that only one sort of thing exists in the world – physical stuff – (...)

    In a recent book, Neil Levy argues that culpable action – action for which we are morally responsible – is necessarily produced by states of which we are consciously aware. However, criminal defendants are routinely held responsible for criminal harm caused by states of which they are not conscious in Levy’s sense. In this chapter I argue that cases of negligent criminal harm indicate that Levy’s claim that moral responsibility requires synchronic conscious awareness of the moral significance of an act (...)

    The emerging neuroscience of psychopathy will have several important implications for our attempts to construct an ethical society. In this article we begin by describing the list of criteria by which psychopaths are diagnosed. We then review four competing neuropsychological theories of psychopathic cognition. The first of these models, Newman’s attentional model, locates the problem in a special type of attentional narrowing that psychopaths have shown in experiments. The second and third, Blair’s amygdala model and Kiehl’s paralimbic model represent the (...)

    Philosophy Labs.Kit Rempala, Katrina Sifferd & Joseph Vukov - 2021 - Teaching Philosophy 44 (2):187-206.
    Conversation is a foundational aspect of philosophical pedagogy. Too often, however, philosophical research becomes disconnected from this dialogue, and is instead conducted as a solitary endeavor. We aim to bridge the disconnect between philosophical pedagogy and research by proposing a novel framework. Philosophy labs, we propose, can function as both a pedagogical tool and a model for conducting group research. Our review of collaborative learning literature suggests that philosophy labs, like traditional STEM labs, can harness group learning models such as (...)

  15. Chemical Castration as Punishment.Katrina L. Sifferd - 2020 - In Thomas Nadelhoffer & Nicole A. Vincent (eds.), Neuro-Interventions and the Law.
    This chapter explores whether chemical castration can be justified as a form of criminal punishment. The author argues that castration via the drug medroxyprogesterone acetate (MPA), or some similar drug, does not achieve the punishment aims of retribution, deterrence, or incapacitation, but might serve as punishment in the form of rehabilitative treatment. However, current U.S. chemical castration statutes are too broad to be justified as rehabilitative. The state is warranted in targeting psychological states in criminal defendants for rehabilitative treatment where (...)

    Child soldiers, who often appear to be both victims and perpetrators, present a vexing moral and legal challenge: how can we protect the rights of children while seeking justice for the victims of war crimes? There has been little stomach, either in domestic or international courts, for prosecuting child soldiers—but neither has this challenge been systematically addressed in international law. Establishing a uniform minimum age of criminal responsibility would be a major step in the right direction; we argue that such (...)

While many scholars have considered the ethical implications of emerging technologies, such as nanotechnology, few have considered their potential impact on crucial institutions such as our criminal justice system. Specifically, I will discuss the implications of two types of technological advances for criminal sentencing: advanced tracking devices enabled by nanotechnology, and nano-neuroscience, including neural implants. The key justifications for criminal punishment- including incapacitation, deterrence, rehabilitation, and retribution – apply very (...)

    In this chapter I use virtue theory to critique certain contemporary punishment practices. From the perspective of virtue theory, respect for rational agency indicates a respect for choice-making as the process by which we form dispositions which in turn give rise to further choices and action. To be a moral agent one must be able to act such that his or her actions deserve praise or blame; virtue theory thus demands that moral agents engage in rational choice-making as a means (...)

  19. Juvenile Self-Control and Legal Responsibility: Building a Scalar Standard.Katrina L. Sifferd, Tyler Fagan & William Hirstein - 2020 - In Alfred Mele (ed.), Surrounding Self-Control.
    US criminal courts have recently moved toward seeing juveniles as inherently less culpable than their adult counterparts, influenced by a growing mass of neuroscientific and psychological evidence. In support of this trend, this chapter argues that the criminal law’s notion of responsible agency requires both the cognitive capacity to understand one’s actions and the volitional control to conform one’s actions to legal standards. These capacities require, among other things, a minimal working set of executive functions—a suite of mental processes, mainly (...)

    Neuroethics is the body of work exploring the ethical, legal, and social implications of neuroscience. This work can be separated into two rough categories. The neuroscience of ethics concerns a neuroscientific understanding of the brain processes that underpin moral judgment and behavior.

  21. What Does It Mean to Be a Mechanism? Stephen Morse, Non-Reductivism, and Mental Causation.Katrina L. Sifferd - 2014 - Criminal Law and Philosophy:1-17.
    Stephen Morse seems to have adopted a controversial position regarding the mindbody relationship: John Searle’s non-reductivism, which claims that conscious mental states are causal yet not reducible to their underlying brain states. Searle’s position has been roundly criticized, with some arguing the theory taken as a whole is incoherent. In this paper I review these criticisms and add my own, concluding that Searle’s position is indeed contradictory, both internally and with regard to Morse's other views. Thus I argue that Morse (...)

    The cases that Doris chronicles of confabulation are similar to perceptual illusions in that, while they show the interstices of our perceptual or cognitive system, they fail to establish that our everyday perception or cognition is not for the most part correct. Doris's account in general lacks the resources to make synchronic assessments of responsibility, partially because it fails to make use of knowledge now available to us about what is happening in the brains of agents.

    In this chapter we will argue that the capacities necessary to moral and legal agency can be understood as executive functions in the brain. Executive functions underwrite both the cognitive and volitional capacities that give agents a fair opportunity to avoid wrongdoing: to recognize their acts as immoral and/or illegal, and to act or refrain from acting based upon this recognition. When a person’s mental illness is serious enough to cause severe disruption of executive functions, she is very likely to (...)

    In this chapter we explore the ethical justifications for criminal detentions prior to adjudication. Because defending pretrial detentions cannot be justified on purely forward-looking grounds, any plausible justification for pre-conviction detention must be partly backward-looking. Reflecting on the aims of the criminal law more broadly suggests that pretrial detentions, like post-conviction detentions, may be justified on “hybrid” grounds—but only if certain backward-looking retributive criteria and forward-looking instrumental criteria are met. We conclude that while it is possible in principle to justify (...)

    This chapter argues that a successful plea of legal insanity ought to rest upon proof that a criminal act is causally related to symptoms of a mental disorder. Diagnosis of a mental disorder can signal to the court that the defendant had very little control over relevant moral ignorance or incompetence. Must we draw the same conclusion for defendants who lack moral knowledge due to miseducation or other extreme environmental conditions, unrelated to a mental disorder?

    Douglas Husak’s book is an intelligent, wide-ranging exploration of the legal principle ‘ignorance of law is no excuse’. This principle is one of the few pieces of legal doctrine known by many regular folks, along with the criminal standard of proof ‘beyond a reasonable doubt’. The traditional approach to the doctrine might be explained in this way: in some cases, ignorance of the law fails to excuse offenders from culpability because as a matter of policy we feel they ought to (...)
