Previous research suggests that free will beliefs and moral responsibility beliefs are strongly linked, yet ultimately distinct. Unfortunately, the most common measure of free will beliefs, the free will subscale (FWS) of the Free Will and Determinism Plus, seems to confound free will beliefs and moral responsibility beliefs. Thus, the present research (1,700 participants across two studies) details the development of a 2-factor FWS – the FWS-II – that divides the FWS into a free will subscale and a moral responsibility (...) subscale. The FWS-II showed good fit compared to standard fit thresholds and superior fit compared to the original FWS. The moral responsibility subscale was moderately correlated with general punitive attitudes and specific punitive assignments, even when controlling for the free will subscale. Conversely, the free will subscale was moderately correlated with conservativism and religiosity, even when controlling for the moral responsibility subscale. These results provide evidence that the FWS is better suited – psychometrically, theoretically, and practically – as a 2-factor measure of free will beliefs and moral responsibility beliefs than as a 1-factor measure of free will beliefs.

The claim that common sense regards free will and moral responsibility as compatible with determinism has played a central role in both analytic and experimental philosophy. In this paper, we show that evidence in favor of this “natural compatibilism” is undermined by the role that indeterministic metaphysical views play in how people construe deterministic scenarios. To demonstrate this, we re-examine two classic studies that have been used to support natural compatibilism. We find that although people give apparently compatibilist responses, this (...) is largely explained by the fact that people import an indeterministic metaphysics into deterministic scenarios when making judgments about freedom and responsibility. We conclude that judgments based on these scenarios are not reliable evidence for natural compatibilism. (shrink)

Some have argued that advances in the science of human decision-making, particularly research on automaticity and unconscious priming, would ultimately thwart our commonsense understanding of free will and moral responsibility. Do people interpret this research as a threat to their self-understanding as free and responsible agents? We approached this question by seeing how feelings of surprise mediate the relationship between personal sense of control and third-personal attributions of free will and responsibility. Across three studies (N = 1,516) we found that (...) people with a greater sense of personal control were more surprised at the results of experiments showing effects of unconscious priming on moral behavior. Surprise differentially mediated the relationship between personal control and attributions of free will and responsibility: people attributed less free will and more responsibility as they were more surprised. This suggests that people exhibit defensive thinking with respect to responsibility, but not free will. (shrink)

Pereboom and Caruso propose the quarantine model as an alternative to existing models of criminal justice. They appeal to the established public health practice of quarantining people, which is believed to be effective and morally justified, to explain why -in criminal justice- it is also morally acceptable to detain wrongdoers, without assuming the existence of a retrospective moral responsibility. Wrongdoers in their model are treated as carriers of dangerous diseases and as such should be preventively detained (or rehabilitated) until they (...) no longer pose a threat to society. Our main concern in this paper is that Pereboom and Caruso adopt an idiosyncratic meaning of quarantine regulations. We highlight a set of important disanalogies between their quarantine model and the quarantine regulations currently adopted in public health policies. More specifically, we argue that the similarities that Pereboom and Caruso propose to substantiate their analogy are not consistent—despite what they claim—with the regulations underlying quarantine as an epidemiological process. We also notice that certain quarantine procedures adopted in public health systems are inadequate to deal with criminal behaviors. On these grounds, we conclude that Pereboom and Caruso should not appeal to the quarantine analogy to substantiate their view, unless they address the issues and criticism we raise in this paper.

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.
