It has often been suggested that people's ordinary understanding of morality involves a belief in objective moral truths and a rejection of moral relativism. The results of six studies call this claim into question. Participants did offer apparently objectivist moral intuitions when considering individuals from their own culture, but they offered increasingly relativist intuitions considering individuals from increasingly different cultures or ways of life. The authors hypothesize that people do not have a fixed commitment to moral objectivism but instead tend (...) to adopt different views depending on the degree to which they consider radically different perspectives on moral questions.

Experimental philosophy is a new interdisciplinary field that uses methods normally associated with psychology to investigate questions normally associated with philosophy. The present review focuses on research in experimental philosophy on four central questions. First, why is it that people's moral judgments appear to influence their intuitions about seemingly nonmoral questions? Second, do people think that moral questions have objective answers, or do they see morality as fundamentally relative? Third, do people believe in free will, and do they see free (...) will as compatible with determinism? Fourth, how do people determine whether an entity is conscious? (shrink)

In this crisply written book, Hanno Sauer offers the first book-length treatment of debunking arguments in ethics, developing an empirically informed and philosophically sophisticated account of genealogical arguments and their significance for the reliability of moral cognition. He breaks new ground by introducing a series of novel distinctions into the current debate, which allows him to develop a framework for assessing the prospects of debunking or vindicating our moral intuitions. He also challenges the justification of some of our moral judgments (...) by showing that they are based on epistemically defective processes. His book is an original, cutting-edge contribution to the burgeoning field of empirically informed metaethics, and will interest philosophers, psychologists, and anyone interested in how - and whether - moral judgment works.

Shows that the very same asymmetries that arise for intentionally also arise from deciding, desiring, in favor of, opposed to, and advocating. It seems that the phenomenon is not due to anything about the concept of intentional action in particular. Rather, the effects observed for the concept of intentional action should be regarded as just one manifestation of the pervasive impact of moral judgment.

Experimental moral philosophy emerged as a methodology in the last decade of the twentieth century, as a branch of the larger experimental philosophy (X-Phi) approach. Experimental moral philosophy is the empirical study of moral intuitions, judgments, and behaviors. Like other forms of experimental philosophy, it involves gathering data using experimental methods and using these data to substantiate, undermine, or revise philosophical theories. In this case, the theories in question concern the nature of moral reasoning and judgment; the extent and sources (...) of moral obligations; the nature of a good person and a good life; even the scope and nature of moral theory itself. This entry begins with a brief look at the historical uses of empirical data in moral theory and goes on to ask what, if anything, is distinctive about experimental moral philosophy—how should we distinguish it from related work in empirical moral psychology? After discussing some strategies for answering this question, the entry examines two of the main projects within experimental moral philosophy, and then discusses some of the most prominent areas of research within the field. As we will see, in some cases experimental moral philosophy has opened up new avenues of investigation, while in other cases it has influenced longstanding debates within moral theory. (shrink)

This paper provides a comprehensive review of the experimental philosophy of action, focusing on the various different accounts of the Knobe Effect.

Recent empirical work calls into question the so-called Simple View that an agent who A’s intentionally intends to A. In experimental studies, ordinary speakers frequently assent to claims that, in certain cases, agents who knowingly behave wrongly intentionally bring about the harm they do; yet the speakers tend to deny that it was the intention of those agents to cause the harm. This paper reports two additional studies that at first appear to support the original ones, but argues that in (...) fact, the evidence of all the studies considered is best understood in terms of the Simple View.

Studying the folk concept of intentional action, Knobe (2003a) discovered a puzzling asymmetry: most people consider some bad side effects as intentional while they consider some good side effects as unintentional. In this study, we extend these findings with new experiments. The first experiment shows that the very same effect can be found in ascriptions of intentionality in the case of means for action. The second and third experiments show that means are nevertheless generally judged more intentional than side effects, (...) and that people do take into account the structure of the action when ascribing intentionality. We then discuss a number of hypotheses that can account for these data, using reactions times from our first experiment. (shrink)

<P>Experimental philosophy is one of the most active and exciting areas in philosophy today. In <EM>Current Controversies in Experimental Philosophy</EM>, Elizabeth O’Neill and Edouard Machery have brought together twelve leading philosophers to debate four topics central to recent research in experimental philosophy.

Intuitions about intentional action have turned out to be sensitive to normative factors: most people say that an indifferent agent brings about an effect of her action intentionally when it is harmful, but unintentionally when it is beneficial. Joshua Knobe explains this asymmetry, which is known as ‘the Knobe effect’, in terms of the moral valence of the effect, arguing that this explanation generalizes to other asymmetries concerning notions as diverse as deciding and being free. I present an alternative explanation (...) of the Knobe effect in terms of normative reasons. This explanation generalizes to other folk psychological notions such as deciding, but not to such notions as being free. I go on to argue, against Knobe, that offering a unified explanation of all the asymmetries he discusses is in fact undesirable. (shrink)

Can an event’s blameworthiness distort whether people see it as intentional? In controversial recent studies, people judged a behavior’s negative side effect intentional even though the agent allegedly had no desire for it to occur. Such a judgment contradicts the standard assumption that desire is a necessary condition of intentionality, and it raises concerns about assessments of intentionality in legal settings. Six studies examined whether blameworthy events distort intentionality judgments. Studies 1 through 4 show that, counter to recent claims, intentionality (...) judgments are systematically guided by variations in the agent’s desire, for moral and nonmoral actions alike. Studies 5 and 6 show that a behavior’s negative side effects are rarely seen as intentional once people are allowed to choose from multiple descriptions of the behavior. Specifically, people distinguish between “knowingly” and “intentionally” bringing about a side effect, even for immoral actions. These studies suggest that intentionality judgments are unaffected by a behavior’s blameworthiness. (shrink)

Recent work by Joshua Knobe has established that people are far more likely to describe bad but foreseen side effects as intentionally performed than good but foreseen side effects (this is sometimes called the 'Knobe effect' or the 'side-effect effect.' Edouard Machery has proposed a novel explanation for this asymmetry: it results from construing the bad side effect as a cost that must be incurred to receive a benefit. In this paper, I argue that Machery's 'trade-off hypothesis' is wrong. I (...) do this by reproducing the asymmetry between judgments about good and bad side effects in cases that cannot plausibly be construed as trade-offs. (shrink)

Recent empirical and conceptual research has shown that moral considerations have an influence on the way we use the adverb 'intentionally'. Here we propose our own account of these phenomena, according to which they arise from the fact that the adverb 'intentionally' has three different meanings that are differently selected by contextual factors, including normative expectations. We argue that our hypotheses can account for most available data and present some new results that support this. We end by discussing the implications (...) of our account for folk psychology. (shrink)

We propose a causal model theory to explain asymmetries in judgments of the intentionality of a foreseen side-effect that is either negative or positive (Knobe, 2003). The theory is implemented as a Bayesian network relating types of mental states, actions, and consequences that integrates previous hypotheses. It appeals to two inferential routes to judgment about the intentionality of someone else's action: bottom-up from action to desire and top-down from character and disposition. Support for the theory comes from three experiments that (...) test the prediction that bottom-up inference should occur only when the actor's primary objective is known. The model fits intentionality judgments reasonably well with no free parameters. (shrink)

Research has consistently shown that people consider harmful side effects of an action more intentional than helpful side effects. This phenomenon is known as the side- effect effect (SEE), which refers to the influence of moral considerations in judgments of intentionality and other non-moral concepts. There is an ongoing debate about how to explain this asymmetric pattern of judgment and the psychological factors involved in it. It has been posited that affective reactions to agents that bring about harmful side- effects (...) could bias intentionality attributions in these cases, explaining the asymmetric pattern of intentionality judgments that we observe in the SEE. We call this the affective bias hypothesis (ABH). Evidence for the ABH is mixed, with some findings suggesting a role for affective processes, while others suggesting that affective processes play no role in the SEE. A possible explanation for these apparently contradictory results points to affective processes involved in the SEE being confined to anger. In a series of empirical studies, we systematically measured and manipulated participants’ anger in order to test this possibility. Our findings suggest that anger play no role in intentionality judgments in SEE cases, while providing support for a non-emotional motivation to blame as a factor underlying the SEE. (shrink)

I am working on a substantially revised second edition of this. It is due to be published by Palgrave in 2024.

The ‘Knobe effect’ is the name given to the empirical finding that judgments about whether an action is intentional or not seems to depend on the moral valence of this action. To account for this phenomenon, Scaife and Webber have recently advanced the ‘Consideration Hypothesis’, according to which people’s ascriptions of intentionality are driven by whether they think the agent took the outcome in consideration when taking his decision. In this paper, I examine Scaife and Webber’s hypothesis and conclude that (...) it is supported neither by the existing literature nor by their own experiments, whose results I did not replicate, and that the ‘Consideration Hypothesis’ is not the best available account of the ‘Knobe Effect’. (shrink)

People asymmetrically attribute various agential features such as intentionality, knowledge, or causal impact to other agents when something of normative significance is at stake. I will argue that three questions are of primary interest in the debate about this effect. A methodological question about how to explain it at all; a substantive question about how to explain it correctly: and a normative question about whether to explain it in terms of an error or a legitimate judgmental pattern. The problem, I (...) argue, is that these three questions are difficult to disentangle. I propose a solution to this problem, and show how it accounts for the most recent data regarding the effect.

Experimental philosophers have discovered a large number of asymmetries in our intuitions about philosophically significant notions. Often those intuitions turned out to be sensitive to normative factors. Whereas optimists have insisted on a unified explanation of these findings, pessimists have argued that it is impossible to formulate a single factor explanation. I defend the intermediate position according to which unification is possible to some extent, but should be pursued within limits. The key issue that I address is how it is (...) possible to set such limits in a way that is true to the phenomena. (shrink)

Joshua Knobe's work has marshaled considerable support for the hypothesis that everyday judgments of whether an action is intentional are systematically influenced by evaluations of the action or agent. The main source of evidence for this hypothesis is a series of surveys that involve an agent either helping or harming something as a side effect. Respondents are much more likely to judge the side effect intentional if harm is involved. It is a remarkable feature of the discussion so far that (...) it assumes without scrutiny that the substitution of one act-type for another could not, taken alone, explain the difference in responses that the two scenarios yield. This paper presents evidence, both experimental and conceptual, that it is precisely this difference that explains the asymmetry in responses. Briefly, agents who token the act-type help must fulfill certain psychological conditions that they don't have to fulfill if they are to token the act-type harm. Harming, unlike helping, does not require the ful.. (shrink)

A majority of people regard the harmful side-effects of an agent’s behavior as much more intentional than an agent’s helpful side-effects. In this paper, I present evidence for a related asymmetry. When a side- effect action is an instance of harming, folk ascriptions are significantly impacted by the relative badness of either an agent’s main goal or her side- effect action, but not her attitude. Yet when a side- effect action is an instance of helping, folk ascriptions are sensitive to (...) an agent’s expressed attitude, but not to the relative goodness of her main goal or side- effect. It seems that the connection between harmful side-effects and intentionality is, for many, uniquely impervious to the expressed attitude of the agent in question. (shrink)

Based on a puzzling pattern in our judgements about intentional action, Knobe [. “Intentional Action and Side-Effects in Ordinary Language.” Analysis 63: 190–194] has claimed that these judgements are shaped by our moral judgements and evaluations. However, this claim goes directly against a key conceptual intuition about intentional action – the “frame-of-mind condition”, according to which judgements about intentional action are about the agent’s frame-of-mind and not about the moral value of his action. To preserve this intuition Hindriks [. “Intentional (...) Action and the Praise-Blame Asymmetry.” The Philosophical Quarterly 58: 630–641;. “Normativity in Action: How to Explain the Knobe Effect and its Relatives.” Mind & Language 29: 51–72] has proposed an alternate account of the Knobe Effect. According to his “Normative Reason account of Intentional Action”, a side-effect counts as intentional only when the agent thought it constituted a normative reason not to act but did not care. In...

Accounts of act individuation have attempted to capture peoples’ pre-theoretic intuitions. Donald Davidson has argued that a multitude of action descriptions designate only one act, while Alvin Goldman has averred that each action description refers to a distinct act. Following on recent empirical studies, I subject these accounts of act individuation to experimentation. The data indicate that people distinguish between actions differently depending upon the moral valence of the outcomes. Thus, the assumption that a single account of act individuation applies (...) invariantly seems mistaken. (shrink)

We often find ourselves thinking of others as boring, nauseating, dim, dodgy, clumsy, or otherwise irritating or unpleasant. What’s the right thing to do when we have such thoughts? Some philosophers argue we ought to be civil and conceal them, lest others pick up on them and feel disrespected. Drawing on experimental psychology and classical Confucianism, I argue otherwise, suggesting that we ought to (literally) doubt such appraisals and be wary of their veracity.

The side-effect effect is the seemingly irrational tendency for people to say harmful side effects were more intentional than helpful side effects of the same action. But the tendency may not be irrational. According to the Tradeoffs Justification Model, judgments of a person's intentions to cause harm depend on how that person decided to act, and on whether the reasons for acting justified causing the harmful consequences. Across three experiments (N = 660), unjustified harms were viewed as more intentional than (...) justified harms. If the person had a choice of what to do and knowingly caused harm for no good reason, people judged that the person must have actually desired and intended to cause the harm. However, if the person had a strong, compelling reason (e.g., to ransom his daughter from kidnappers) that the observer deemed to have justified causing the harm, then observers thought the harm was weakly intended at most. Taboo harms that violated sacred moral values were especially likely to be seen as intentional because most reasons do not adequately justify violating a sacred value. (shrink)
