Ermakoff distinguishes several mechanisms of alignment in troubled and uncertain times and assesses their significance through a fine-grained examination of actors’ beliefs, shifts in perceptions, and subjective states. To this end, he draws on the analytical and methodological resources of perspectives that usually stand apart: primary historical research, formal decision theory, the phenomenology of group processes, quantitative analyses, and the hermeneutics of testimonies. In elaborating this dialogue across disciplinary boundaries, Ruling Oneself Out restores the complexity and indeterminate character of pivotal collective decisions and demonstrates that an in-depth historical exploration can lay bare processes of crucial importance for understanding the formation of political preferences, the paradox of self-deception, and the makeup of historical events as highly consequential.
