Responding to recent concerns about the reliability of the published literature in psychology and other disciplines, we formed the X-Phi Replicability Project to estimate the reproducibility of experimental philosophy. Drawing on a representative sample of 40 x-phi studies published between 2003 and 2015, we enlisted 20 research teams across 8 countries to conduct a high-quality replication of each study in order to compare the results to the original published findings. We found that x-phi studies – as represented in our sample (...) – successfully replicated about 70% of the time. We discuss possible reasons for this relatively high replication rate in the field of experimental philosophy and offer suggestions for best research practices going forward. (shrink)

Recent and puzzling experimental results suggest that people’s judgments as to whether or not an action was performed intentionally are sensitive to moral considerations. In this paper, we outline these results and evaluate two accounts which purport to explain them. We then describe a recent experiment that allegedly vindicates one of these accounts and present our own findings to show that it fails to do so. Finally, we present additional data suggesting no such vindication could be in the offing and (...) that, in fact, both accounts fail to explain the initial, puzzling results they were purported to explain.

Philosophers have tended to construe friendship as an intimate relationship involving mutual love, and have focused their discussions on this ‘true’ form of friendship. However, everyone recognizes that we use the word ‘friend’ and its cognates to refer, non-ironically, to those with whom we share various relationships that are not terribly intimate or which do not involve mutual love. I argue that there exists no general reason to restrict our philosophical focus to ‘true’ friendships, and allege that we can gain (...) important insights if we broaden our perspective to include lesser friends. I contend that friendships, in the broad sense (encompassing both ‘true’ and lesser forms), are necessarily relationships that are the product of significant collaborative norm manipulation. And I argue that understanding friendship in this way helps explain important features, including the difference between friendships and familiar relations, the non-fungibility of friends, and why friendships are often in flux.

Abstract: Recently, the experimental philosopher Joshua Knobe has shown that the folk are more inclined to describe side effects as intentional actions when they bring about bad results. Edouard Machery has offered an intriguing new explanation of Knobe's work—the 'trade-off hypothesis'—which denies that moral considerations explain folk applications of the concept of intentional action. We critique Machery's hypothesis and offer empirical evidence against it. We also evaluate the current state of the debate concerning the concept of intentionality, and argue that, (...) given the number of variables at play, any parsimonious account of the relevant data is implausible.

According to the discontinuity view, people recognize a deep discontinuity between phenomenal and intentional states, such that they refrain from attributing feelings and experiences to entities that do not have the right kind of body, though they may attribute thoughts to entities that lack a biological body, like corporations, robots, and disembodied souls. We examine some of the research that has been used to motivate the discontinuity view. Specifically, we focus on experiments that examine people's aptness judgments for various mental (...) state ascriptions to groups. These studies seem to reveal that people are more inclined to think of groups as having intentionality than as having phenomenology. Combined with the fact that groups obviously lack a single biological body, this has been taken as evidence that people operate according to the relevant discontinuity. However, these studies support discontinuity only on the assumption that the experimental participants are interpreting the relevant group mental state ascriptions in a specific way. We present evidence that people are not interpreting these ascriptions in a way that supports discontinuity. Instead, we argue that people generally interpret group mental state ascriptions distributively, as attributions of mental states to various group members. (shrink)

Philosophical tradition has long held that free will is necessary for moral responsibility. We report experimental results that show that the folk do not think free will is necessary for moral responsibility. Our results also suggest that experimental investigation of the relationship is ill served by a focus on incompatibilism versus compatibilism. We propose an alternative framework for empirical moral psychology in which judgments of free will and moral responsibility can vary independently in response to many factors. We also suggest (...) that, in response to some factors, the necessity relation may run from responsibility to free will. (shrink)

Philosophers of mind typically group experiential states together and distinguish these from intentional states on the basis of their purportedly obvious phenomenal character. Sytsma and Machery (Phil Stud 151(2): 299–327, 2010) challenge this dichotomy by presenting evidence that non-philosophers do not classify subjective experiences relative to a state’s phenomenological character, but rather by its valence. However we argue that S&M’s results do not speak to folk beliefs about the nature of experiential states, but rather to folk beliefs about the entity (...) to which those experiential states are attributed. In two experiments, we demonstrate that ordinary attributions of subjective experiences (of smell and felt emotions) to a simple robot are not sensitive to valence, but instead respond to functional assumptions about the entity to which the states are (or are not) attributed.

Many moral philosophers have assumed that ordinary folk embrace moral objectivism. But, if so, why do folk embrace objectivism? One possibility is the pervasive connection between religion and morality in ordinary life. Some theorists contend that God is viewed as a divine guarantor of right and wrong, rendering morality universal and absolute. But is belief in God per se sufficient for moral objectivism? In this paper, we present original research exploring the connections between metaethics and particular conceptions of God among (...) religious participants. Study 1 shows that, when controlling for religiosity, age, and belief in God’s loving characteristics, it is belief in God’s punishing characteristics (specifically, the existence of Hell) that uniquely predicts rejection of moral relativism. Study 2 shows that followers of Abrahamic faiths are more likely to endorse moral objectivism when thinking of the Divine, regardless of loving or punishing characteristics. And Study 3 shows that priming for moral objectivism makes theists more likely to endorse God’s punishing characteristics. A general picture is suggested by these data. For Abrahamic theists, God’s particular characteristics are not germane to the question of whether his moral commandments are real and objective. And while theists strongly endorse God’s loving characteristics, focusing on the objective nature of morality can highlight God’s punishing nature, reminding theists that objective morality requires a divine guarantor of justice to enforce it.

We evaluate the role of embodiment in ordinary mental state ascriptions. Presented are five experiments on phenomenal state ascriptions to disembodied entities such as ghosts and spirits. Results suggest that biological embodiment is not a central principle of folk psychology guiding ascriptions of phenomenal consciousness. By contrast, results continue to support the important role of functional considerations in theory of mind judgments.

Philosophers have alleged that paraphrases of metaphors are inadequate. They have presented this inadequacy as a datum predicted by, and thus a reason to accept, particular accounts of ‘metaphorical meanings.’ But to what, specifically, does this inadequacy claim amount? I argue that, if this assumption is to have any bearing on the metaphor debate, it must be construed as the comparative claim that paraphrases of metaphors are inadequate compared to paraphrases of literal utterances. But the evidence philosophers have offered does (...) not support the comparative inadequacy of paraphrases of metaphors. I offer my own empirical evidence against the inadequacy assumption.

We argue that the causal account offered by analytic functionalism provides the best account of the folk psychological theory of mind, and that people ordinarily define mental states relative to the causal roles these states occupy in relation to environmental impingements, external behaviors, and other mental states. We present new empirical evidence, as well as review several key studies on mental state ascription to diverse types of entities such as robots, cyborgs, corporations and God, and explain how this evidence supports (...) a functional account. We also respond to two challenges to this view based on the embodiment hypothesis, or the claim that physical realizers matter over and above functional role, and qualia. In both cases we conclude that research to date best supports a functional account of ordinary mental state concepts. (shrink)

In the past several decades, psychologists and linguists have begun experimentally investigating linguistic pragmatic phenomena. They share the assumption that the best way to study the use of language in context incorporates an experimental methodology, here understood to comprise controlled studies and careful field observations. This article surveys some key projects in experimental pragmatics and relates these projects to ongoing philosophical discussions.

Cathy Mason (2020) argues – against my position in Phelan (2019) – that significant norm-manipulation is unnecessary for friendship. Instead, she holds that norm manipulation is a, perhaps omnipresent, causal result of the very feature I deny as necessary to friendship: mutual caring or love. Mason’s counter-examples allow for further explication of the norm-manipulation view of friendship. However, they do not constitute a compelling challenge to that view, because they do not seem to involve collaborative norm manipulation at all. Instead, (...) they are better described as cases in which people come to be subject to established cultural norms they were not previously subject to, because they voluntarily come to fall under a distinctive relationship relative to one another.

Pragmatics is the study of the role of context in communication. This chapter discusses experimental research in pragmatics. It provides clarity on pragmatics by contrasting the role of context in communication with the role of sentence meaning. There is some disagreement about which communicative effects are due to which thing, so there is some disagreement as to where to draw the boundary between semantics and pragmatics. The chapter considers a rich experimental research project in pragmatics, which has developed primarily within (...) linguistics and psychology over the course of the last several decades in response to the boundary disputes. Finally, it talks about a more nascent experimental research project, which, building upon insights from psychology, aims towards understanding survey pragmatics. These two projects are discussed and attention is paid to the methods unique to each project and the philosophical and linguistic underpinnings they share in common. (shrink)

This short paper, forthcoming as part of a symposium on experimental philosophy to appear in the popular publication, The Philosophers’ Magazine (including contributions by Papineau, Stich, Machery, Sommers, and Knobe), offers an accessible summary of seven years of experimental-philosophical research into intentional action attributions.

The desire for parsimony – to posit as few explanatory features as possible – has a rich philosophical history and is often given lots of weight in philosophical theory construction. But, as the psychologist Tania Lombrozo has demonstrated, our bias in favour of parsimony can lead us to adopt simple explanations even when it’s far more likely that a complicated explanation is correct.

Sally and Sid have worked together for a while, and Sally knows Sid to be a hard worker. She might make this point about him by saying, “Sid is a hard worker.” Or, she might make it by saying, “Sid is a Sherman tank.” We all recognize that there is some distinction between the first assertion, in which Sally is speaking literally, and the second, in which she is speaking figuratively. This is a distinction that any theory of figurative language (...) worth its salt should capture. But, as I will argue, it is a distinction that contemporary accounts of figurative language fail to successfully explain. This is because such theories have been mostly concerned to explore the nature of figurative understanding and the status of figurative meanings. Perhaps proponents of these theories suppose that, by appealing to a special kind of figurative meaning, we can eventually explain the difference between speaking literally and speaking figuratively. I believe this approach gets the order of explanation backwards. I contend that accounts of figurative meaning and understanding can only be fully articulated against a prior account of the distinction between figurative and literal language. What’s more, once my account of figurative language is in place, we can begin to see why people bother speaking figuratively at all, or so I will argue. (shrink)
