Luck for Moral Luck?

In their article “No Luck for Moral Luck” (Kneer and Machery Cognition, 182, 331-348 2019), the authors claim to have dissolved the philosophical puzzle of resultant moral luck through empirical studies that show that people do not judge morally lucky and morally unlucky agents differently. In this paper, I will argue that one can accept the results of their experiment and still uphold the puzzle of resultant moral luck. In order to do so, I will first turn to Machery’s suggestion that implicit biases should be viewed as traits instead of mental states and introduce three levels of moral commitment. I will use the distinctions made in Machery (2016) to argue that Kneer and Machery’s experiments test respondents’ second-level moral commitments but that the puzzle of moral luck is actually about third-level moral commitments which are indicative of traits that manifest in practice. I will make this point by returning to Nagel's article (Williams and Nagel 1976) and arguing that the original puzzle of resultant moral luck is best described as a puzzle about moral practice rather than moral theory. As a result, Kneer and Machery’s analysis does not show that people do not have a Difference Intuition as they claim, but only that they have a second-level theoretical commitment to the control principle, which is a conclusion that should have been expected given Nagel’s formulation of the problem.
