 For the most recent work in the coherence project, see Neufeld 2022. For the most recent work in the diversity project, see Gaus 2021. Gaus’s work has pushed public reason so far in a diversity direction that in some ways it is no longer a form of social contract theory (Gaus 2018). Gaus now models the choice of principles as a socially interdependent choice process, and not a single agreement. Gaus even began developing a research program based on these insights called the New Diversity Theory (Gaus 2018b).
