Do stakes affect ordinary knowledge ascriptions? Epistemic contextualists and interest relative invariantist claim that stakes do play a role in ordinary knowledge ascription. But results from a large scale cross-cultural study we conducted suggested otherwise. We collected data on people’s judgments in response to high and low stakes versions of “Bank Cases”. The cases were translated into 14 different languages and data was collected from 4504 people across nineteen sites, spanning fifteen countries. In every site sampled, we find that stakes (...) do not play a role in ordinary knowledge ascriptions. In light of the surprising cross-cultural robustness of our findings, we suggest that the scales tilt against epistemic contextualism and interest-relative invariantism and that a version of classical invariantism about knowledge should perhaps be taken seriously.

This article examines whether people share the Gettier intuition (viz. that someone who has a true justified belief that p may nonetheless fail to know that p) in 24 sites, located in 23 countries (counting Hong-Kong as a distinct country) and across 17 languages. We also consider the possible influence of gender and personality on this intuition with a very large sample size. Finally, we examine whether the Gettier intuition varies across people as a function of their disposition to engage (...) in “reflective” thinking. (shrink)

Is behavioral integration (i.e., which occurs when a subjects assertion that p matches her non-verbal behavior) a necessary feature of belief in folk psychology? Our data from nearly 6,000 people across twenty-six samples, spanning twenty-two countries suggests that it is not. Given the surprising cross-cultural robustness of our findings, we suggest that the types of evidence for the ascription of a belief are, at least in some circumstances, lexicographically ordered: assertions are first taken into account, and when an agent sincerely (...) asserts that p, non-linguistic behavioral evidence is disregarded. In light of this, we take ourselves to have discovered a universal principle governing the ascription of beliefs in folk psychology. (shrink)

Nichols and Bruno claim that the folk judge that psychological continuity is necessary for personal identity. In this article, we evaluate this claim. First, we argue that it is likely that in thinking about hypothetical cases of transformations, the folk do not use a unitary concept of personal identity, but instead rely on different concepts of ‘person’, ‘identity’, and ‘individual’. Identity can be ascribed even when post-transformation individuals are no longer categorized as persons. Second, we provide new empirical evidence suggesting (...) that the folk do not consider psychological continuity to be necessary for an individual to be categorized as a person or for ascribing identity over time and through transformations. In this, we assume, along with Nichols and Bruno, that folk judgments about identity can be read off the use of proper names. Furthermore, we raise some doubts about the ability of current experimental designs to adequately distinguish between qualitative and numerical identity jud.. (shrink)

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)

The question of transtemporal identity of objects in general and persons in particular is an important issue in both philosophy and psychology. While the focus of philosophers traditionally was on questions of the nature of identity relation and criteria that allow to settle ontological issues about identity, psychologists are mostly concerned with how people think about identity, and how they track identity of objects and people through time. In this article, we critically engage with widespread use of inferring folk judgments (...) of identity from study participants’ use of proper names in response to experimental vignettes. We provide reasons to doubt that using this method one can reliably infer judgments of numerical identity over time and transformations. We also critically examine allegedly-Kripkean justification of this method and find it lacking. Merely assuming that names are rigid designators will not help. A study participant’s use of proper names can be taken to track the participant’s identity judgments only if supported by the participant’s belief that names used in the scenario are used rigidly.
