A persistent question in discussions of the ethics of advance directives for euthanasia is whether patients who go through deep psychological changes retain their identity. Rather than seek an account of identity that answers this question, I argue that responsible policy should directly address indeterminacy about identity directly. Three sorts of indeterminacy are distinguished. Two of these—epistemic indeterminacy and metaphysical indeterminacy—should be addressed in laws/policies regarding advance directives for euthanasia.

People narrating the experience of dysregulated anger after a brain injury call upon metaphor in patterned ways to help them make sense of their situation. Here, I analyze the use of the metaphor of the doubled self in a personal narrative of brain injury, and I situate this metaphor in its cultural history by analyzing Dr Jekyll and Mr Hyde and The Incredible Hulk as landmark moments in its development. A pattern of thought reflecting Seneca’s philosophy on the incompatibility of (...) anger with rational selfhood emerges. I discuss implications for the way we care for people struggling with post-brain-injury anger. (shrink)

In the paper, after clarifying terms such as ‘identity’, ‘self’ and ‘personhood’, I propose an empirical account of identity based on the notion of “whole phenotype”. This move allows one to claim the persistence of the individuals before and after their being affected by dementia. Furthermore, I show how this account permits us to address significant questions related to demented individuals’ loss of the capacity of moral decisions.

To what extent do aesthetic taste and our interest in the arts constitute who we are? In this paper, we present a series of empirical findings that suggest an Aesthetic Self Effect supporting the claim that our aesthetic engagements are a central component of our identity. Counterfactual changes in aesthetic preferences, for example, moving from liking classical music to liking pop, are perceived as altering us as a person. The Aesthetic Self Effect is as strong as the impact of moral (...) changes, such as altering political partisanship or religious orientation, and significantly stronger than for other categories of taste, such as food preferences. Using a multidimensional scaling technique to map perceived aesthetic similarities among musical genres, we determined that aesthetic distances between genres correlate highly with the perceived difference in identity. Further studies generalize the Aesthetic Self Effect beyond the musical domain: general changes in visual art preferences, for example from more traditional to abstract art, also elicited a strong Self Effect. Exploring the breadth of this effect we also found an Anaesthetic Self Effect. That is, hypothetical changes from aesthetic indifference to caring about music, art, or beauty are judged to have a significant impact on identity. This effect on identity is stronger for aesthetic fields compared to leisure activities, such as hiking or playing video games. Across our studies, the Anaesthetic Self Effect turns out to be stronger than the Aesthetic Self Effect. Taken together, we found evidence for a link between aesthetics and identity: we are aesthetic selves. When our tastes in music and the arts or our aesthetic interests change we take these to be transformative changes. (shrink)

Why is it that forgetting moral knowledge, unlike other paradigmatic examples of knowledge, seems so deeply absurd? Previous authors have given accounts whereby moral forgetting in itself either is uniformly absurd and impossible or is possible and only the speech act is absurd. Considering findings in moral psychology and the experimental philosophy of personal identity, I argue that the knowledge of some moral truths—especially those that are emotional, widely held, subjectively important, and contribute to social relationships—cannot be forgotten because they’re (...) too tightly tied to one’s true self. Moral knowledge at the level of individual propositions, when it does not have these attributes and so is not so tied to the agent’s identity, can sometimes be forgotten. I identify two such cases: where the moral knowledge results partly from an emotional trigger that has been forgotten, and where the moral knowledge results partly from a process of reflection that has been forgotten.

Recent research has begun treating the perennial philosophical question, “what makes a person the same over time?” as an empirical question. A long tradition in philosophy holds that psychological continuity and connectedness of memories are at the heart of personal identity. More recent experimental work, following Strohminger & Nichols (2014), has suggested that persistence of moral character, more than memories, is perceived as essential for personal identity. While there is a growing body of evidence supporting these findings, a critique by (...) Starmans & Bloom (2018) suggests that this research program conflates personal identity with mere similarity. To address this criticism, we explore how loss of someone’s morality or memories influence perceptions of identity change, and perceptions of moral duties towards the target of the change. We present participants with a classic ‘body switch’ thought experiment and after assessing perceptions of identity persistence, we present a moral dilemma, asking participants to imagine that one of the patients must die (Study 1) or be left alone in a care home for the rest of their life (Study 2). Our results highlight the importance of the continuity of moral character, suggesting lay intuitions are tracking (something like) personal identity, not just mere similarity. (shrink)

A long tradition of psychological research has explored the distinction between characteristics that are part of the self and those that lie outside of it. Recently, a surge of research has begun examining a further distinction. Even among characteristics that are internal to the self, people pick out a subset as belonging to the true self. These factors are judged as making people who they really are, deep down. In this paper, we introduce the concept of the true self and (...) identify features that distinguish people’s understanding of the true self from their understanding of the self more generally. In particular, we consider recent findings that the true self is perceived as positive and moral, and that this tendency is actor-observer invariant and cross-culturally stable. We then explore possible explanations for these findings and discuss their implications for a variety of issues in psychology. (shrink)

The personal identity relation is of great interest to philosophers, who often consider fictional scenarios to test what features seem to make persons persist through time. But often real examples of neuroscientific interest also provide important tests of personal identity. One such example is the case of Phineas Gage – or at least the story often told about Phineas Gage. Many cite Gage’s story as example of severed personal identity; Phineas underwent such a tremendous change that Gage “survived as a (...) different man.” I discuss a recent empirical finding about judgments about this hypothetical. It is not just the magnitude of the change that affects identity judgment; it is also the negative direction of the change. I present an experiment suggesting that direction of change also affects neuroethical judgments. I conclude we should consider carefully the way in which improvements and deteriorations affect attributions of personal identity. This is particularly important since a number of the most crucial neuroethical decisions involve varieties of cognitive enhancements or deteriorations. (shrink)

When explaining human actions, people usually focus on a small subset of potential causes. What leads us to prefer certain explanations for valenced actions over others? The present studies indicate that our moral attitudes often predict our explanatory preferences far better than our beliefs about how causally sensitive actions are to features of the actor's environment. Study 1 found that high-prejudice participants were much more likely to endorse non-agential explanations of an erotic same-sex encounter, such as that one of the (...) men endured a stressful event earlier that day. Study 2 manipulated participants' beliefs about how the agent's behavior depended on features of his environment, finding that such beliefs played no clear role in modeling participants' explanatory preferences. This result emerged both with low- and high-prejudice, US and Indian participants, suggesting that these findings probably reflect a species-typical feature of human psychology. Study 3 found that moral attitudes also predicted explanations for a woman's decision to abort her pregnancy (3a) and a person's decision to convert to Islam (3b). Study 4 found that luck in an action's etiology tends to undermine perceptions of blame more readily than perceptions of praise. Finally, Study 5 found that when explaining support for a rival ideology, both Liberals and Conservatives downplay agential causes while emphasizing environmental ones. Taken together, these studies indicate that our explanatory preferences often reflect a powerful tendency to represent agents as possessing virtuous true selves. Consequently, situation-focused explanations often appear salient because people resist attributing negatively valenced actions to the true self. There is a person/situation distinction, but it is normative. (shrink)

Our aim in this entry is to articulate the state of the art in the moral psychology of personal identity. We begin by discussing the major philosophical theories of personal identity, including their shortcomings. We then turn to recent psychological work on personal identity and the self, investigations that often illuminate our person-related normative concerns. We conclude by discussing the implications of this psychological work for some contemporary philosophical theories and suggesting fruitful areas for future work on personal identity.

Having positive moral traits is central to one’s sense of self, and people generally are motivated to maintain a positive view of the self in the present. But it remains unclear how people foster a positive, morally good view of the self in the present. We suggest that recollecting and reflecting on moral and immoral actions from the personal past jointly help to construct a morally good view of the current self in complementary ways. More specifically, across four studies we (...) investigated the extent to which people believe they have changed over time after recollecting their own moral or immoral behaviors from the personal past. Our results indicate that recollecting past immoral actions is associated with stronger impressions of dissimilarity and change in the sense of self over time than recollecting past moral actions. These effects held for diverse domains of morality (i.e., honesty/dishonesty, helping/harming, fairness/unfairness, and loyalty/disloyalty), and they remained even after accounting for objective, calendar time. Further supporting a motivational explanation, these effects held when people recollected their own past actions but not when they recollected the actions of other people. (shrink)

People maintain a positive identity in at least two ways: They evaluate themselves more favorably than other people, and they judge themselves to be better now than they were in the past. Both strategies rely on autobiographical memories. The authors investigate the role of autobiographical memories of lying and emotional harm in maintaining a positive identity. For memories of lying to or emotionally harming others, participants judge their own actions as less morally wrong and less negative than those in which (...) other people lied to or emotionally harmed them. Furthermore, people judge those actions that happened further in the past to be more morally wrong than those that happened more recently. Finally, for periods of the past when they believed that they were very different people than they are now, participants judge their actions to be more morally wrong and more negative than those actions from periods of their pasts when they believed that they were very similar to who they are now. The authors discuss these findings in relation to theories about the function of autobiographical memory and moral cognition in constructing and perceiving the self over time. (shrink)
