This article examines the emergence of a Developmental Character-Based Discourse in post-revolutionary Iran (1989–2001). The dominant revolutionary discourse initially emphasized “innate guidance” and a “divine human being,” rendering early character narratives unrelated to developmentalism. The war’s end and practical necessities revived character-based discourse. The core question is how this shift from “revolutionary essentialism” to a “Developmental Character-Based Discourse” occurred and was reconfigured in cultural and social policymaking. The shift emerged through a realignment of official discourse that redefined “backwardness” as a threat to Islamic values and promoted “civilization-building.” Developmentalist social and political scientists, stressing the measurement and management of Iranian “attitudes” and “character traits,” played a pivotal role. Alongside state institutions—especially IRIB and the Supreme Council of Cultural Policy—they constructed a new character-driven subjectivity aligned with state developmental objectives. This project crystallized in initiatives like the “Survey of Iranian Values and Attitudes,” which aimed not to empower society but to control and harmonize behaviors to establish a desirable “social order” and support economic development. Thus, the discourse moderated public expectations and legitimized state economic and cultural policies. Without analyzing such surveys directly, this study explores the historical context that made them relevant.
