In the era of digital technological dominance, data have become a strategic instrument of cultural, cognitive, and political control. Data colonialism refers to the reproduction of colonial structures through surveillance and platform-based mechanisms, illustrating how global technological powers, through the ownership, extraction, and processing of user data, seek cognitive penetration and the transformation of national identities. This study aims to examine the role of data colonialism in the design and advancement of cognitive warfare against the Islamic Republic of Iran by conducting a qualitative thematic analysis of the “Second Step of the Revolution” statement. The research seeks to answer how data colonialism is represented within the statement and what functions it performs in perception engineering and the weakening of revolutionary consciousness. The research method employs qualitative content analysis using ATLAS.ti software. Through open coding and thematic categorization, the semantic network of the statement was extracted. A total of 28 key quotations were identified and analyzed, resulting in 267 conceptual codes organized into seven sub-themes and one overarching theme. The principal sub-themes include: halting the process of civilization-building; distortion of reality and cognitive inversion; weakening the younger generation; inducing perceptions of inefficiency; disconnection from historical memory; promotion of Western lifestyles; and political perception engineering. The findings indicate that data colonialism functions as a tool of cognitive warfare aimed at constructing alternative narratives, eroding social trust, emptying cultural capital, and inducing perceptions of spiritual collapse. It operates not only at economic and technological levels but also at epistemological and identity-based dimensions. Within the discourse of the Second Step statement, data are conceptualized not merely as informational resources but as instruments of psychological and cultural domination—used for truth inversion, collective memory distortion, and weakening revolutionary will. Consequently, the study concludes that data colonialism is not solely a technological or economic issue but an epistemicide and identity-eroding project.
