The experimental validity of research in the experimental philosophy of free will has been called into question. Several new, important studies (Murray et al. forthcoming; Nadelhoffer et al., Cognitive Science 44 (8): 1–28, 2020 ; Nadelhoffer et al., 2021; Rose et al., Cognitive Science 41 (2): 482–502, 2017 ) are interpreted as showing that the vignette-judgment model is defective because participants only exhibit a surface-level comprehension and not the deeper comprehension the model requires. Participants, it is argued, commit _bypassing_, _intrusion_, (...) and _fatalism_ errors. We respond in two ways: (1) we critique and improve existing methods for assessing deeper comprehension and (2) we develop videos to convey deterministic principles of change that succeed in significantly reducing participants’ bypassing, intrusion, and fatalism errors. Consequently, we have the best existing instrument for gauging folk intuitions about the relationship between free will and determinism. (shrink)

Belief in substance dualism, the idea that mind and matter are two different kinds of substances, has been found to be a strong predictor of belief in free will. Why? Here, we test whether believing that mind and matter are different kinds of substance correlates with differences in how people think of free will and/or differences in how people interpret the scenarios used to test their conceptions. We provided participants (N = 515) with two hypothetical scenarios where the world was (...) presented either as deterministic or not and asked them whether they thought that a given decision could be free in that world. Incompatibilist free will requires that determinism, the idea that at any instant only one possible future can follow from the state of the world, is false. Compatibilists hold that free will is possible even if determinism is true. In this study, we investigate if substance dualists are more compatibilist. We find that they are not, and that both dualists and physicalists agree that free will is incompatible with determinism. In addition, we show that dualists and physicalists are equally likely to commit bypassing, i.e., to misinterpret determinism as excluding mental causation. We also show that dualists have a stronger tendency to commit intrusion, i.e., to misinterpret determinism by importing indeterministic metaphysics into their interpretation of deterministic descriptions.

Experimental work on free will typically relies on deterministic stimuli to elicit judgments of free will. We call this the Vignette-Judgment model. We outline a problem with research based on this model. It seems that people either fail to respond to the deterministic aspects of vignettes when making judgments or that their understanding of determinism differs from researcher expectations. We provide some empirical evidence for this claim. In the end, we argue that people seem to lack facility with the concept (...) of determinism, which calls into question the validity of experimental work operating under the Vignette-Judgment model. We also argue that alternative experimental paradigms are unlikely to elicit judgments that are philosophically relevant to questions about the metaphysics of free will. (shrink)

The purpose of this chapter is to provide a guide for conducting thought experiments in epistemology effectively. The guide raises several considerations for best practices when using this research method. Several weaknesses in the way thought experiments are conducted are also identified and several suggestions are reviewed for how to improve them. Training in these research techniques promotes more productive scholarship in epistemology, saves time and resources wasted on less efficient approaches, and reduces the risk that researchers are fooling themselves (...) when they use thought experiments in philosophy.

In a recent paper, I argued that philosophical intuitions are surprisingly robust both across demographic groups and across development. Machery and Stich reply by reviewing a series of studies that do show significant differences in philosophical intuition between different demographic groups. This is a helpful point, which gets at precisely the issues that are most relevant here. However, even when one looks at those very studies, one finds truly surprising robustness. In other words, despite the presence of statistically significant differences (...) between demographic groups, a core finding coming out of those studies is that philosophical intuitions are surprisingly robust across demographic groups.

In order to be doing something intentionally, must one know that one is doing it? Some philosophers have answered yes. Our aim is to test a version of this knowledge thesis, what we call the Knowledge/awareness Thesis, or KAT. KAT states that an agent is doing something intentionally only if he knows that he is doing it or is aware that he is doing it. Here, using vignettes featuring skilled action and vignettes featuring habitual action, we provide evidence that, in (...) various scenarios, a majority of non-specialists regard agents as intentionally doing things that the agents do not know they are doing and are not aware of doing. This puts pressure on proponents of KAT and leaves it to them to find a way these results can coexist with KAT. (shrink)

Theories of free will are often measured against how well they capture everyday intuitions about free will. But what are these everyday intuitions, and what theoretical commitments do they express? Empirical methods have delivered mixed messages. In response, some free will theorists have developed error theories to undermine the credentials of countervailing intuitions. These efforts are predicated on the idea that people might misunderstand determinism in any of several ways. This paper sheds light on the comprehension problem. We first discuss (...) recent efforts to explain systematic errors in how people interpret determinism. Then, we present the alarming results of two new preregistered studies exploring three types of comprehension failure: (a) epiphenomenal bypassing, (b) fatalistic bypassing, and (c) indeterministic intrusion. Our findings suggest that misunderstanding runs deeper than others have supposed. This casts doubt on existing models of commonsense thinking about free will. Unless and until researchers properly control for the kinds of misunderstandings we identify, research on free will intuitions cannot shed light on whether ordinary thinking reflects commitments to compatibilism or incompatibilism.

The Challenge from Cognitive Diversity (CCD) states that demography-specific intuitions are unsuited to play evidential roles in philosophy. The CCD attracted much attention in recent years, in great part due to the launch of an international research effort to test for demographic variation in philosophical intuitions. In the wake of these international studies the CCD may prove revolutionary. For, if these studies uncover demographic differences in intuitions, then in line with the CCD there would be a good reason to challenge (...) philosophical views that rely on those intuitions for evidential support. I argue that philosophical views that rely on demography-specific intuitions for evidential support need not be threatened by such findings. I first provide a detailed analysis of the epistemological principles driving the CCD and distinguish three formulations of this challenge. I then show that there are good reasons to reject all such formulations of the CCD. (shrink)

Philosophers are divided on whether it is possible to intend believed-impossible outcomes. Several thought experiments in the action theory literature suggest that this is conceptually possible, though they have not been tested in ordinary social cognition. We conducted three experiments to determine whether, on the ordinary view, it is conceptually possible to intend believed-impossible outcomes. Our findings indicate that participants firmly countenance the possibility of intending believed-impossible outcomes, suggesting that it is conceptually possible to intend to do something that one (...) believes is impossible.

In a series of pre-registered studies, we explored (a) the difference between people’s intuitions about indeterministic scenarios and their intuitions about deterministic scenarios, (b) the difference between people’s intuitions about indeterministic scenarios and their intuitions about neurodeterministic scenarios (that is, scenarios where the determinism is described at the neurological level), (c) the difference between people’s intuitions about neutral scenarios (e.g., walking a dog in the park) and their intuitions about negatively valenced scenarios (e.g., murdering a stranger), and (d) the difference (...) between people’s intuitions about free will and responsibility in response to first-person scenarios and third-person scenarios. We predicted that once we focused participants’ attention on the two different abilities to do otherwise available to agents in indeterministic and deterministic scenarios, their intuitions would support natural incompatibilism—the view that laypersons judge that free will and moral responsibility are incompatible with determinism. This prediction was borne out by our findings. (shrink)

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)

Natural/social kind essentialism is the view that natural kind categories, both living and non-living natural kinds, as well as social kinds (e.g., race, gender), are essentialized. On this view, artifactual kinds are not essentialized. Our view—teleological essentialism—is that a broad range of categories are essentialized in terms of teleology, including artifacts. Utilizing the same kinds of experiments typically used to provide evidence of essentialist thinking—involving superficial change (study 1), transformation of insides (study 2) and inferences about offspring (study 3)—we find (...) support for the view that a broad range of categories—living natural kinds, non-living natural kinds and artifactual kinds—are essentialized in terms of teleology. Study 4 tests a unique prediction of teleological essentialism and also provides evidence that people make inferences about purposes which in turn guide categorization judgments. (shrink)

Philosophers have long debated whether, if determinism is true, we should hold people morally responsible for their actions since in a deterministic universe, people are arguably not the ultimate source of their actions nor could they have done otherwise if initial conditions and the laws of nature are held fixed. To reveal how non-philosophers ordinarily reason about the conditions for free will, we conducted a cross-cultural and cross-linguistic survey (N = 5,268) spanning twenty countries and sixteen languages. Overall, participants tended (...) to ascribe moral responsibility whether the perpetrator lacked sourcehood or alternate possibilities. However, for American, European, and Middle Eastern participants, being the ultimate source of one’s actions promoted perceptions of free will and control as well as ascriptions of blame and punishment. By contrast, being the source of one’s actions was not particularly salient to Asian participants. Finally, across cultures, participants exhibiting greater cognitive reflection were more likely to view free will as incompatible with causal determinism. We discuss these findings in light of documented cultural differences in the tendency toward dispositional versus situational attributions. (shrink)

In this article, we will identify two issues that deserve greater attention from those researching lay people’s attitudes to moral responsibility and determinism. The first issue concerns whether people interpret the term “moral responsibility” in a retributive way and whether they are motivated to hold offenders responsible for pre-determined behaviour by considerations other than retributivism, e.g. the desires to condemn the action and to protect society. The second issue concerns whether explicitly rejecting moral responsibility and retributivism, after reading about determinism, (...) would have any impact on “implicit” retributivism when recommending a sentence for a hypothetical offender. We will report the results of an exploratory study that investigated these questions. Our preliminary findings raise the possibility that a significant proportion of participants either i) may not interpret “moral responsibility” in the basic, retributive sense of the term, which is at issue in the determinism debate, or ii) may be unconsciously motivated by non-retributive considerations to judge that the offender is morally responsible, in the basic, retributive sense. If this is confirmed by future research, a wider implication would be that theorists’ arguments against retributivism are more likely to affect public attitudes to punishment when non-retributive ways of achieving important punishment goals are emphasised. Our preliminary findings also suggested that explicit retributivism did not correlate with implicit retributivism. If this is confirmed in future research, it would imply that free will theorists who wish to affect public attitudes toward punishment should, when communicating their research to the public, give detailed consideration to the implications for sentencing.

Many have argued we have a moral obligation to assist others in need, but given the scope of global suffering, how far does this obligation extend? According to one traditional philosophical view, the obligation to help others is limited by our ability to help them, or by the principle that “ought implies can”. This view is primarily defended on the grounds that it is a core principle of commonsense moral psychology. This paper reviews findings from experimental philosophy in cognitive science (...) demonstrating that “ought implies can” is rejected by moral psychology. Researchers find that moral obligations are ascribed to agents who cannot fulfill them, suggesting that moral requirements do sometimes extend beyond what we are able to do. This research furthers our understanding of moral obligation, identifies an important need for further cross-cultural work in moral psychology, and demonstrates a way in which scientific experimentation can be applied to improve upon the conceptual analysis of important philosophical concepts in normative ethics.

Abstract:In this article, we present a pragmatic approach to neuroethics, referring back to John Dewey and his articulation of the “common good” and its discovery through systematic methods. Pragmatic neuroethics bridges philosophy and social sciences and, at a very basic level, considers that ethics is not dissociable from lived experiences and everyday moral choices. We reflect on the integration between empirical methods and normative questions, using as our platform recent bioethical and neuropsychological research into moral cognition, action, and experience. Finally, (...) we present the protocol of a study concerning teenagers’ morality in everyday life, discussing our epistemological choices as an example of a pragmatic approach in empirical ethics. We hope that this article conveys that even though the scope of neuroethics is broad, it is important not to move too far from the real life encounters that give rise to moral questions in the first place.
