Scepticism about Virtue and the Five-Factor Model of Personality

Published online by Cambridge University Press:  28 November 2016

University of St,


Considerable progress in personality and social psychology has been largely ignored by philosophers, many of whom still remain sceptical concerning whether the conception of character presupposed by virtue theory is descriptively adequate. Here, I employ the five-factor model of personality, currently the consensus view in personality psychology, to respond to a strong reading of the situationist challenge, whereby most people lack dispositions that are both cross-situationally consistent and temporally stable. I show that situationists rely on a false dichotomy between character traits and situations, and that evidence supports the empirical adequacy of the sorts of character traits presupposed by virtue ethics. Additionally, I suggest that the personality traits of the five-factor model are relevant to virtue theory, in so far as they are malleable, morally salient, and seem to structurally parallel Aristotelian virtues and vices. Thus, contra situationism, the five-factor model supports the descriptive adequacy of a virtue-theoretical framework.

2 I concentrate on ‘virtue ethics’ as opposed to virtue theory in general, although most of what I have to say applies, mutatis mutandis, to any ethics which presupposes character traits saliently like those presupposed by virtue ethics.

3 In this article I focus on situationism as a philosophical, as opposed to psychological, position. Whereas situationist psychologists, such as Ross and Nisbett in Ross, L. and Nisbett, R. E., The Person and the Situation (New York, 1991)Google Scholar, posit the primacy of situations in explaining behaviour on the basis of experimental evidence, philosophical situationists, such as Doris in e.g. Doris, J. M., Lack of Character (Cambridge, 2002)CrossRefGoogle Scholar and Harman in e.g. Harman, G., ‘Moral Philosophy Meets Social Psychology: Virtue Ethics and the Fundamental Attribution Error’, Proceedings of the Aristotelian Society 99 (1999), pp. 315–31CrossRefGoogle Scholar, concentrate on the implications of such work in psychology for philosophical theories like virtue ethics.

4 I shall ignore differences between ‘character’ and ‘personality’ traits since I take the situationist challenge, under the strong interpretation which I will presently develop, to pertain, as Doris puts it, ‘not so much [to] what distinguishes character and personality traits as what they have in common: behavioral consistency as the primary criterion of attribution’ (Doris, Lack of Character, p. 20).

19 Although, as I have suggested, it is not the widespread existence of the virtues and vices per se that is best seen as the main situationist target, occasional remarks in the debate seem to invite such a reading, such as Doris's comment that the exceptions to situationist findings in experiments such as those mentioned above only ‘prove the rule’ (Lack of Character, p. 60). Moreover, more often than not, situationists will remain silent concerning the few subjects who, for instance, do stop to help while in a hurry, refuse to administer shocks, help whether or not they find a dime, and so on.

20 Sabini, J. and Silver, M., ‘Lack of Character? Situationism Critiqued’, Ethics 115 (2005), pp. 535–62CrossRefGoogle Scholar, especially at 537, 545, 561–2, also seem to suggest that this is the only pernicious reading of situationism.

21 Since Doris's and Harman's challenges appeared, situationism has developed, so it is important to bear in mind that I am not refuting, and cannot here refute, all versions of the challenge. Recently, for instance, Merritt, M. W., Doris, J. M. and Harman, G., ‘Character’, The Moral Psychology Handbook, ed. Doris, J. M. and The Moral Psychology Research Group (Oxford, 2010), pp. 355–92CrossRefGoogle Scholar, took issue not with people's lack of cross-situational consistency and temporal stability of traits, which they claim is no longer ‘much in dispute’ (p. 358). Instead, Merritt et al. targeted the assumption that the conception of practical rationality built into certain Aristotelian conceptions of virtue ethics is empirically viable. Though this is an important question in its own right, I think that my arguments here leave it open for the most part. For the question of whether there exist global traits (understood as traits meeting conditions (i) and (ii) above) is largely orthogonal to whether or not such traits are the result of (conscious) practical reasoning, or largely unconscious affective-cognitive dispositions.

22 This claim, in turn, can be understood in different ways. It may be that global traits are psychologically impossible. However, since situationist arguments rely on experiments in empirical psychology, it is unclear how these could establish psychological impossibility. Alternatively, it may be that human psychology, for the most part, is infertile soil for the cultivation of global traits, since most people lack global traits. But since virtues and vices are global traits, most people lack the psychological resources for virtue.

23 Compare: ‘(1) If behavior is typically ordered by robust traits, systematic observation will reveal pervasive behavioral consistency. (2) Systematic observation does not reveal pervasive behavioral consistency. (3) Behavior is not typically ordered by robust traits’ (Merritt et al., ‘Character’, pp. 357–8).

30 This approach to traits echoes the CAPS approach (see e.g. Mischel, W. and Soda, Y., ‘A Cognitive-Affective System Theory of Personality: Reconceptualizing Situations, Dispositions, Dynamics, and Invariance in Personality Structure’, Psychological Review 102 (1995), pp. 246–68CrossRefGoogle Scholar), which, according to Miller, C., Character and Moral Psychology (Oxford, 2014)CrossRefGoogle Scholar, ch. 5, provides a sophisticated framework for our folk-psychological trait discourse, and has recently been employed by philosophers building their own, empirically informed theories of virtue, as witness Russell, D., Practical Intelligence and the Virtues (Oxford, 2009)CrossRefGoogle Scholar and Snow, N., Virtue as Social Intelligence: An Empirically Grounded Theory (New York, 2009)Google Scholar. Although I take what I say here to be compatible with such views, my aim is not to construct a new theory of character traits, but rather to rely on current personality psychology to undermine situationism, on the one hand, and possibly rekindle trust in virtue ethics, on the other. The CAPS model itself is compatible with the five-factor model discussed below, and often thought to simply elucidate different aspects of personality rather than articulate a distinct conception of traits (see McAdams, D. P. and Olson, B. D., ‘Personality Development: Continuity and Change Over the Life-Course’, Annual Review of Psychology 61 (2010), pp. 517–42CrossRefGoogle ScholarPubMed). Much of what I say here, then, will predictably be compatible with that view.

34 Debate is ongoing concerning whether more dimensions should be added. For example, the HEXACO model is like FFM with the addition of ‘honesty/humility’. See, e.g. Ashton, M.

Alfano, M., Character as Moral Fiction (New York, 2013), pp. 52–3CrossRefGoogle Scholar, basically dismisses it as irrelevant to virtue ethics within two pages. However, in his more recent Alfano, M., Moral Psychology: An Introduction (Cambridge, 2016), pp. 130–2Google Scholar, Alfano is less pessimistic concerning the prospects for the FFM, suggesting that evidence for the model highlights the need to take personality into account if we are to offer any adequate explanation of human behaviour.

66 I should note that any correlations in the .30 ballpark mentioned in this section are not subject to the criticism that correlation coefficients for personality measures stagnate at around .30, which mainly concerns single-item behavioural measures (as Doris, Lack of Character, p. 72 acknowledges), since the correlations cited herein concern meta-analytic results for predictions of major life outcomes (almost inevitably containing a wide range of results if they are any good), as well as moment-by-moment behavioural predictions. Questioning the importance of .30 correlations for such measures manifests insensitivity to our subject matter, namely human psychology.

86 This remark may require some clarification, for someone who has a mean score on a given dimension may be thought to not have a trait. For instance, consider the dimension of Neuroticism; someone may be on the high or low end; but someone may also be in the middle, thereby seeming to be neither neurotic nor the contrary. Hence, it may be said, such a person might appear to be trait-less at least vis-à-vis Neuroticism. But to think so would be a mistake. On the FFM (as on Aristotelian ethics) someone who has a mean score may be said to have an affective-cognitive disposition to behave, etc. in a way that lies somewhere in between those of the person who is very high and the one who is very low in Neuroticism. To illustrate, on pain of oversimplification, someone with a mean score on neuroticism will probably be neither insensitive to all danger and threat (as someone exceptionally low might), nor interpret every difficulty as a hint of impending doom (as someone very high might). But this does not mean that one with the score in question would not be disposed (i.e. have a disposition) to respond in certain characteristic ways in trait-relevant situations, even if we lack a term for this trait.

100 This should be interpreted with caution, for it would be a gross oversimplification to think that however high one scores on these dimensions, it is always for the better. Indeed, the links between extreme scores on FFM dimensions and pathologies should seriously undermine our confidence in such scenarios.

105 Some situationists (e.g. Olin and Doris, ‘Vicious Minds’; Alfano, Character as Moral Fiction, pp. 111-80) have recently targeted the epistemic virtues.

However, the story I offer is compatible with such views as Miller's, for instance, according to whom most people have ‘mixed traits’, comprising some features that we would describe as virtuous and others which seem vicious.
