Moral psychology investigates human functioning in moral contexts, and asks how these results may impact debate in ethical theory. This work is necessarily interdisciplinary, drawing on both the empirical resources of the human sciences and the conceptual resources of philosophical ethics. The present article discusses several topics that illustrate this type of inquiry: thought experiments, responsibility, character, egoism v . altruism, and moral disagreement.

Some research suggests that moral behavior can be strongly influenced by trivial features of the environment of which we are completely unaware. Philosophers, psychologists, and neuroscientists have argued that these findings undermine our commonsense notions of agency and responsibility, both of which emphasize the role of practical reasoning and conscious deliberation in action. We present the results of four vignette-based studies (N = 1,437) designed to investigate how people think about the metaphysical and moral implications of scientific findings that reveal (...) our susceptibility to automaticity and situational influences. When presented with lightly fictionalized narratives about these findings, participants exhibit no tendency toward changing judgments of freedom and responsibility compared to control groups. This suggests that people seem unwilling to adopt skeptical attitudes about agency on the basis of these scientific findings. (shrink)

Two debates in contemporary philosophical moral psychology have so far been conducted almost entirely in isolation from one another despite their structural similarity. One is the debate over the importance for virtue ethics of the results of situational manipulation experiments in social psychology. The other is the debate over the ethical implications of experiments that reveal gender and race biases in social cognition. In both cases, the ethical problem posed cannot be identified without first clarifying the cognitive structures underlying the (...) problematic phenomena. In this chapter, I argue that the two kinds of phenomena share a basic cognitive structure, which is well articulated by the findings of the empirical psychology of attitudes, especially if these findings are understood in the context of the cognitive-affective system theory of personality. On the basis of this joint construal of situationism and implicit bias, I argue that the negative programme of ethical improvement that many philosophers recommend in response to one or other problem is unrealistic. Instead, we should consider more seriously the prospects of the positive programme of ethical improvement recommended by Aristotle, the direct aim of which is to instil deeply in ourselves the values at the heart of each of the virtues.

This paper proposes the idea of thinking about practical rationality in terms of self-regulation and defends the thesis that self-regulation is a virtue, insofar as we have reason to think it is our highest form of practical rationality. I argue that understanding self-regulation as a virtuous form of practical reasoning is called for given the kinds of limitations we face in developing agency and pursuing our goals, and presents us with several advantages over traditional understandings of practical rationality.

Why are people trustworthy? I argue for two theses. First, we cannot explain many socially important forms of trustworthiness solely in terms of the instrumentally rational seeking of one’s interests, in response to external sanctions or rewards. A richer psychology is required. So, second, possession of moral character is a plausible explanation of some socially important instances when people are trustworthy. I defend this conclusion against the influential account of trust as ‘encapsulated interest’, given by Russell Hardin, on which most (...) trustworthiness is explained by the interest of continuing relationship.
