The authors in this collection start with the insight that not all instances of semiotic indeterminacy are produced in the same way, that they can be located differently in the process of semiosis, and this fact shapes how and when semiotic indeterminacy is deployed by formulators and interpreters. The authors explore patterned uses of semiotic indeterminacy in Brazil, Bulgaria, Iran, and the United States to examine the role indeterminacy plays in institutional attempts at control and persuasion.
