==Philosophical work== Chang's principal research interests lie in normative ethics, metaethics, action theory and moral psychology. Her work focuses on practical conflict, the nature of reasons and values and their relations, and rational agency. She is known for arguing that the structure of value is not what is commonly assumed: like space and time, which is not structured as we think it is, the normative and evaluative realm is not structured as we think it is. In particular, she is known for arguing that two items which are neither better nor worse than one another and yet not equally good may nevertheless be comparable: they may be 'on a par'.<ref name="newapps" /><ref name="sep1" /> If correct, her view has wide-ranging implications for axiology, normative theory, decision theory, economic choice theory, and rationality. Her work also develops a view of rational agency, 'hybrid voluntarism', according to which rational agents are not merely discoverers of reasons but creators of them through the activity of commitment.<ref name="ca" /> She has also written on value pluralism and social choice. She has given various public lectures on decision-making, love, and commitment.

Chang is the author of ''Making Comparisons Count,'' and the editor of the first volume on the topic of incommensurability of values in the Anglo-American world, ''Incommensurability, Incomparability, and Practical Reason'',<ref name="z6Wrn" /> and has authored articles and book chapters.

Ruth Chang is also widely known for her work on 'hard choices' and decision-making, and her research has been the subject of radio, newspaper, and magazine articles.<ref name="DKPgK" />
