Recent empirical work appears to suggest that the moral intuitions of professional philosophers are just as vulnerable to distorting psychological factors as are those of ordinary people. This paper assesses these recent tests of the ‘expertise defense’ of philosophical intuition. I argue that the use of familiar cases and principles constitutes a methodological problem. Since these items are familiar to philosophers, but not ordinary people, the two subject groups do not confront identical cognitive tasks. Reflection on this point shows that (...) these findings do not threaten philosophical expertise—though we can draw lessons for more effective empirical tests. (shrink)

A recent article in Neuroethics posited “bad news for conservatives,” on the basis of survey data collected on line. On the basis of bivariate correlations between self-reported conservatism/liberalism and a variety of moral propositions, the author inferred that those moral judgments were ‘conservative’ or ‘liberal.’ Then, based on a series of bivariate correlations between those same moral propositions and measures of “morally worrisome” personality characteristics, the author concluded that conservatives tended to have these morally worrisome characteristics. Unfortunately, the original article (...) was replete with methodological and statistical errors. This paper presents a reanalysis of the data from the original article, using good statistical and methodological technique. The reanalysis suggests that there are some small but potentially theoretically meaningful relationships between some moral propositions and three morally worrisome (antisocial) personality characteristics. The data also suggest that these relationships can change substantially depending on other conditions, so should not yet be generalized. (shrink)

We review evidence showing that disagreement in folk and expert philosophical intuitions can be predicted by global, heritable personality traits. The review focuses on recent studies of intuitions about free will, ethics, and intentional action. These findings are philosophically important because they suggest that while some projects cannot be done, other projects must take individual differences in philosophical character into account. But care needs to be taken when interpreting the implications of these individual differences. We illustrate one way that these (...) differences have been abused. We then illustrate two ways that these findings can be legitimately used to help illuminate philosophical issues. Given the large and readily available body of evidence, neglect of persistent and predictable philosophical differences is irresponsible. (shrink)

Recent metaphilosophical debates have focused on the methods/epistemology of philosophy, and the structure of the discipline. The paper reports the results of an exploratory study examining the relationship between personality and both kinds of metaphilosophical view. The findings reported are No important link between personality and attitudes to intuitions, Apparent differences between experts and non-experts as to which subfields are considered central, Only limited evidence that perceptions of centrality are related to personality in minor ways. Although no dramatic relationships between (...) personality and metaphilosophical view are found, the results nonetheless prompt some reflection about the role played by judgements about the centrality of subfields within the discipline.

Cognitive scientists have revealed systematic errors in human reasoning. There is disagreement about what these errors indicate about human rationality, but one upshot seems clear: human reasoning does not seem to fit traditional views of human rationality. This concern about rationality has made its way through various fields and has recently caught the attention of philosophers. The concern is that if philosophers are prone to systematic errors in reasoning, then the integrity of philosophy would be threatened. In this paper, I (...) present some of the more famous work in cognitive science that has marshaled this concern. Then I present reasons to think that those with training in philosophy will be less prone to certain systematic errors in reasoning. The suggestion is that if philosophers could be shown to be less prone to such errors, then the worries about the integrity of philosophy could be constrained. Then I present evidence that, according to performance on the CRT (Frederick 2005), those who have benefited from training and selection in philosophy are indeed less prone to one kind of systematic error: irrationally arbitrating between intuitive and reflective responses. Nonetheless, philosophers are not entirely immune to this systematic error, and their proclivity for this error is statistically related to their responses to a variety of philosophical questions. So, while the evidence herein puts constraints on the worries about the integrity of philosophy, it by no means eliminates these worries. The conclusion, then, is that the present evidence offers prima facie reasons to ascribe a mitigated privilege to philosophers' ability to rationally arbitrate between intuitive and reflective responses.
