Philosophers have often appealed to intuitive judgments in various thought experiments to support or reject particular theses. Experimental philosophy is an emerging discipline that examines the cognitive nature of such intuitive judgments. In this paper, we assess the methodological and epistemological status of experimental philosophy. We focus on the Knobe effect, in which our intuitive judgment of the intentionality of an action seems to depend on the perceived moral status of that action. The debate on the philosophical implications of the (...) Knobe effect has been framed in terms of the distinction between the competence and performance of the concept of intentionality. Some scholars seem to suggest that the Knobe effect reflects the competence (or otherwise, the performance error) of the concept of intentionality. However, we argue that these notions are purely functional and thus do not have philosophical implications, without assuming normativism, which we see as problematic in a psychological methodology. Finally, focusing on the gap between competence and rationality, we suggest future directions for experimental philosophy. (shrink)

An important theme in recent experimental philosophy is that certain judgements (e.g. our judgements involving intentional action and causation) exhibit a kind of normative penetration whereby, in spite of a not-obviously-normative subject matter, they turn out to be sensitive to, and co-vary with, our normative attitudes in interesting and surprising ways. We present the results of several new experimental studies that suggest that our judgements about feasibility also appear to exhibit this kind of normative penetration in at least some cases; (...) that the best explanation of it involves attributing to subjects a certain kind of extensional error that results from conflating the question at hand with another question that is more salient given their normative attitudes; and that these conclusions have significant, though not straightforward, implications for our understanding of both normative penetration and feasibility, respectively.

A large body of research has found that people judge bad foreseen side effects to be more intentional than good ones. While the standard interpretation of this Side-Effect Effect takes it to show that the ordinary concept of intentionality is influenced by normative considerations, a competing account holds that it is the result of pragmatic pressure to express moral censure and, thus, that the SEE is an experimental artifact. Attempts to confirm this account have previously been unsuccessful, but Lindauer and (...) Southwood :181–186, 2021) present a study that appears to provide support for it, by cancelling the SEE. We are not convinced. Here, we detail three studies testing their interpretation. The results indicate that it is the purported cancellation, rather than the SEE, that is an experimental artifact.

Certain recent experiments are often taken to show that people are far more likely to classify a foreseen side-effect of an action as intentional when that side-effect has some negative normative valence. While there is some disagreement over the details, there is broad consensus among experimental philosophers that this is the finding. We challenge this consensus by presenting an alternative interpretation of the experiments, according to which they show that a side-effect is classified as intentional only if the agent considered (...) its relative importance when deciding on the action. We present two new experiments whose results can be explained by our hypothesis but not by any version of the consensus view. In the course of doing so, we develop a methodological critique of the previous literature on this topic and draw from it lessons for future experimental philosophy research. (shrink)

In Unfit for the Future, Ingmar Persson and Julian Savulescu present a sophisticated argument in defense of the imperative of moral enhancement. They claim that without moral enhancement, the future of humanity is seriously compromised. The possibility of ultimate harm, caused by a dreadful terrorist attack or by a final unpreventable escalation of the present environmental crisis aggravated by the availability of cognitive enhancement, makes moral enhancement a top priority. It may be considered optimistic to think that our present moral (...) capabilities can be successfully improved by means of moral education, moral persuasion, and fear of punishment. So, without moral enhancement, drastic restrictions on human freedom would become the only alternative to prevent those dramatic potential outcomes. In this article, I will try to show that we still have reason to be less pessimistic and that Persson & Savulescu’s arguments are fortunately unconvincing. (shrink)

One aim of this article is to explore the connection between the Knobe effect and the epistemic side-effect effect (ESEE). Additionally, we report evidence about a further generalization regarding probability judgments. We demonstrate that all effects can be found within German material, using ‘absichtlich’ [intentionally], ‘wissen’ [know] and ‘wahrscheinlich’ [likely]. As the explanations discussed with regard to the Knobe effect do not suffice to explicate the ESEE, we survey whether the characteristic asymmetry in knowledge judgments is caused by a differing (...) perception of probabilities concerning the occurrence of the side-effects. Our findings show that a negative side-effect is judged more probable, even if the objective probabilities would suggest otherwise. We argue that the best explanation for these results is that the Knobe effect applies to the perception of probabilities as well: a probabilistic side-effect effect. (shrink)

Skill or control is commonly regarded as a necessary condition for intentional action. This received wisdom is challenged by experiments conducted by Joshua Knobe and Thomas Nadelhoffer, which suggest that moral considerations sometimes trump considerations of skill and control. I argue that this effect (as well as the Knobe effect) can be explained in terms of the role normative reasons play in the concept of intentional action. This explanation has significant advantages over its rivals. It involves at most a conservative (...) extension rather than a radical revision of what we tend to believe about intentional action, and it fits better with the way we conceive of the relation between intentional action and moral responsibility.

Abstract: Recent experimental research on the 'Knobe effect' suggests, somewhat surprisingly, that there is a bi-directional relation between attributions of intentional action and evaluative considerations. We defend a novel account of this phenomenon that exploits two factors: (i) an intuitive asymmetry in judgments of responsibility (e.g. praise/blame) and (ii) the fact that intentionality commonly connects the evaluative status of actions to the responsibility of actors. We present the results of several new studies that provide empirical evidence in support of this (...) account while disconfirming various currently prominent alternative accounts. We end by discussing some implications of this account for folk psychology. (shrink)

During the past two decades, an interest among philosophers in fictitious and illusory beliefs has sprung up in fields ranging anywhere from mathematics and modality to morality.1 In this paper, we focus primarily on the view that Saul Smilansky has dubbed “free will illusionism”—i.e., the purportedly descriptive claim that most people have illusory beliefs concerning the existence of libertarian free will, coupled with the normative claim that because dispelling these illusory beliefs would produce negative personal and societal consequences, those of (...) us who happen to know the dangerous and gloomy truth about the non-existence of libertarian free will should simply keep quiet in the name of the common good.

ZusammenfassungDem sogenannten Knobe-Effekt zufolge bestimmt die moralische Valenz von Nebeneffekten menschlichen Verhaltens die Zuschreibung ihrer absichtlichen Verursachung. Wir argumentieren, dass erstens die empirisch ermittelten sozialpsychologischen Daten den Knobe-Effekt in der üblichen Lesart nicht belegen, vor allem wegen der unvollständigen Untersuchung der entscheidenden moralischen Varianzfaktoren. Zweitens zeigen wir, dass - und wie - eine spezifische Version des traditionellen Prinzips des Doppeleffekts den empirisch bestätigten Teil des Knobe-Effekts philosophisch erklärt. Die Erklärungskraft des Prinzips des Doppeleffekts kann auch als eine Rechtfertigung eben dieses (...) Prinzips gesehen werden. (shrink)

Recent work by Joshua Knobe has established that people are 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)

The Knobe effect is the phenomenon demonstrated in the course of repeated studies showing that moral valence affects the way in which we apply concepts. Knobe explains the effect by appealing to the nature of the concepts themselves: whether they actually apply in some situation depends upon the moral valence of some element of that situation. In this paper, a different picture of the effect is presented and given motivation. It is suggested that subjects apply concepts on the basis of (...) substitution inferences. It is attempted to show that this picture is incompatible with, but preferable to, Knobe’s theory. In closing, some further observations and suggestions are given with respect to further research into the apparent effect of moral valence. (shrink)

Chandra Sripada's (2010) Deep Self Concordance Account aims to explain various asymmetries in people's judgments of intentional action. On this account, people distinguish between an agent's active and deep self; attitude attributions to the agent's deep self are then presumed to play a causal role in people's intentionality ascriptions. Two judgments are supposed to play a role in these attributions?a judgment that specifies the attitude at issue and one that indicates that the attitude is robust (Sripada & Konrath, 2011). In (...) this article, we show that the Deep Self Concordance Account, as it is currently articulated, is unacceptable. (shrink)

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)

Recently, a number of philosophers have advanced a surprising conclusion: people's judgments about whether an agent brought about an outcome intentionally are pervasively influenced by normative considerations. In this paper, we investigate the ‘Chairman case’, an influential case from this literature and disagree with this conclusion. Using a statistical method called structural path modeling, we show that people's attributions of intentional action to an agent are driven not by normative assessments, but rather by attributions of underlying values and characterological dispositions (...) to the agent. In a second study, we examined people's judgments about what they think drives asymmetric intuitions in the Chairman case and found that people are highly inaccurate in identifying which features of the case their intuitions track. In the final part of the paper, we discuss how the statistical methods used in this study can help philosophers with the critical features problem, the problem of figuring out which among the myriad features present in hypothetical cases are the critical ones that our intuitions are responsive to. We show how the methods used in this study have some advantages over both armchair methods used by traditional philosophers and survey methods used by experimental philosophers. (shrink)

Thomas Nadelhoffer claims that a morally praiseworthy agent cannot knowingly produce a morally positive side effect. I claim that the argument Nadelhoffer uses to establish this claim has two false premises. The two false premises are: If something is a side effect, then it is not desired or intended; and If agent S is morally praiseworthy and knows that her performing p will produce a morally positive q, then q forms part of S's reason for p-ing. I offer a counterexample (...) that shows the falsity of and . 2012 APA, all rights reserved). (shrink)
