EVALUATIVE FOCUS: A DUAL-PROCESS VIEW OF MORAL JUDGMENT Ivar Allan Rodriguez Hannikainen A thesis submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy Department of Philosophy University of Sheffield February 2014 1 ii Abstract In this dissertation, I aim to develop an empirical account of moral judgment. Chapter 1 lays some philosophical and methodological groundwork. Next, in Chapters 2 and 3, I review and critically discuss past literature on moral judgment. In recent decades, automaticity research has led to the view that our social judgments are conducted automatically, and uncontrolled by conscious reasoning. In Chapter 2, I push back against this view, arguing that moral judgments are readily shaped by reasoning processes. Next, in Chapter 3, I differentiate a few empirical claims about the relationship between affective processes and moral judgment, and I arbitrate between them. I then aim to characterize the psychological processes that cause these affective responses, arguing for the involvement of a sensory and motor simulation of the behavior. This exercise gives rise to new empirical hypotheses, which are then tested in Chapters 4 and 5. In Chapter 4, I present a collaborative, empirical study that examines the aversions to harmful and disgusting behavior. Our results suggest that – across both purity and harm –condemnation of immoral behavior arises principally from a personal aversion to performing the target action, which shapes third-party judgments through the partly unconscious simulation of the agent‘s perspective. In Chapter 5, I present some analyses that examine the broader influence of evaluative focus on moral and political attitudes. Finally, Chapter 6 argues that the proposed psychological account of moral judgment is consistent with evidence from a wider range of disciplines, from neuroscience and animal cognition, to evolutionary theory and sociology of religion.

I am equally grateful to Stephen Laurence and Fiery Cushman for their invaluable mentorship and support. I would also like to especially mention Ryan Miller for a fruitful collaboration, and James Lenman for his thoughtful comments on previous drafts. I have been lucky to take part in three exceptional research environments: the Philosophy Department at Sheffield, the Moral Cognition Lab at Harvard, and the Moral Psychology Research Lab at Brown. Each of these has afforded me countless valuable discussions. I will name a few whose feedback has been particularly instructive: Bernardo Aguilera, Dan Bartels, Alek Chakroff, Ryan Doran, James Dungan, Josh Greene, Jon Haidt, Josh Rottman, and Liane Young. Finally, I should also thank Regan Bernhard, Kyle Dillon, and Bay McCulloch for their assistance in conducting the experimental research reported in Chapters 4 and 5, and my family and friends whose relentless encouragement and support I could not have done without. iii iv Table of Contents Chapter 1.
