What Follows from the Problem of Ignorance?

ABSTRACT In Power Without Knowledge, Jeffrey Friedman develops a critique of social science to argue that current technocratic practices are prone to predictive failures and unintended consequences. However, he does not provide evidence that the cause he singles out—“ideational heterogeneity”—is in fact a non-negligible source of technocratic limitations, more than or alongside better-known problems such as missing data, measurement issues, interpretive difficulties, and researcher bias. Even if we grant ideational heterogeneity, Friedman’s preferred institutional solution of exitocracy does not necessarily follow. His critical epistemology would also be compatible with radical forms of collective action.
