In one of the earlier influential papers in the field of experimental philosophy titled Normativity and Epistemic Intuitions published in 2001, Jonathan M. Weinberg, Shaun Nichols and Stephen Stich reported that respondents answered Gettier type questions differently depending on their ethnic background as well as socioeconomic status. There is currently a debate going on, on the significance of the results of Weinberg et al. (2001) and its implications for philosophical methodology in general and epistemology in specific. Despite the debates, however, (...) to our knowledge, there has not been a replication attempt of the experiments of the original paper. We collected data from four different sources (two on-line and two in-person) to replicate the experiments. Despite several different data sets and in various cases larger sample sizes and hence greater power to detect differences, we failed to detect significant differences between the above-mentioned ethnic and socioeconomic groups. Our results suggest that epistemic intuitions are more robust across ethnic and socioeconomic groups than Weinberg et al. (2001) indicates. Given our data, we believe that the notion of differences in epistemic intuitions among different ethnic and socioeconomic groups that follows from Weinberg et al. (2001) needs to be corrected.

: Psychological explanations of philosophical intuitions can help us assess their evidentiary value, and our warrant for accepting them. To explain and assess conceptual or classificatory intuitions about specific situations, some philosophers have suggested explanations which invoke heuristic rules proposed by cognitive psychologists. The present paper extends this approach of intuition assessment by heuristics-based explanation, in two ways: It motivates the proposal of a new heuristic, and shows that this metaphor heuristic helps explain important but neglected intuitions: general factual intuitions (...) which have been highly influential in the philosophies of mind and perception but neglected in on-going debates in the epistemology of philosophy. To do so, the paper integrates results from three philosophically pertinent but hitherto largely unconnected strands of psychological research: research on intuitive judgement, analogy and metaphor, and memory-based processing, respectively. The paper shows that the heuristics-based explanation thus obtained satisfies the key requirements cognitive psychologists impose on such explanations, that it can explain the philosophical intuitions targeted, and that this explanation supports normative assessment of the intuitions' evidentiary value: It reveals whether particular intuitions are due to proper exercise of cognitive competencies or constitute cognitive illusions.

Frankfurt-Style Cases (FSCs) seem to elicit the intuitive judgment that an agent is morally responsible despite being unable to act otherwise, which is supposed to falsify the Principle of Alternative Possibility (PAP). Recent empirical studies have shown that the inclination toward this intuitive judgment is shared among people, which seems to reinforce the argument against the PAP. However, some scholars have argued for Descriptive Anti-Intuitionism (DAI) — intuitive judgments have never played an evidential role in philosophy — and thus denied (...) the philosophical significance of such empirical findings. I point out that although DAI fails in its literal claim for FSCs, an associated insight remains potent: an intuitive judgment is so fragile that it can be easily defeated by further arguments. Nevertheless, I argue, empirical studies are significant in uncovering the general principles to which we are committed in our practice concerning moral responsibility. I clarify how such findings can play a robust evidential role in philosophical debates concerning moral responsibility by tracing the literature written by Frankfurt and philosophers. (shrink)

The field of experimental philosophy has received considerable attention, essentially for producing results that seem highly counter-intuitive and at the same time question some of the fundamental methods used in philosophy. A substantial part of this attention has focused on the role of intuitions in philosophical methodology. One of the major contributions of experimental philosophy on this topic has been concrete evidence in support of intuitional diversity; the idea that intuitions vary systematically depending on variables such as ethnicity, socioeconomic background, (...) or gender. Because of the important implications, these findings have been the subject of extensive debate. Despite the seeming significance of the findings and despite all the debates that the experimental philosophy movement has prompted, what has not been examined systematically is the reproducibility of the results. Instead, the reported findings have been simply accepted as established facts. We set out to replicate a wide range of experiments and surprisingly failed to reproduce many of the reported findings, some of which are from the most cited and attention grabbing papers of the field. We draw two conclusions from our findings. The first is that the instability of intuitions has been exaggerated by experimental philosophers. Intuitions appear to be more uniform across different demographic groups. The argument that intuitions need to be discarded because they depend on arbitrary factors such as ethnicity, socioeconomic background, or gender does not seem tenable anymore. The second conclusion is that experimental philosophy needs a better system to ensure the reproducibility of published findings. The current research-publication system of various empirical fields, especially those employing statistical methods, leads to an overproduction of false-positive findings in the published literature. Unless changes are made to the current research-publication system, this overproduction is likely to continue, in experimental philosophy as well as other disciplines. (shrink)
