Not many years ago both anthropology and political science experienced internal disputes—in the first case over the publication of a book accusing a noted anthropologist of endangering indigenous subjects and in the second over the nature of the field. While the first led to polarization, the second produced a partial convergence and modest reforms. This article examines the two processes and seeks the key mechanisms that produced those differences, closing with a call for broadening the study of contentious politics to cover non-public controversies like the ones examined in this article.
