The Essentialist Glitch: Western Individualism and the Performance of Difference in Twinship

This paper examines how identical twins navigate individuality within a cultural framework that assumes identity is singular, visible, and easily recognized. It asks: how can individuality be understood when both biological similarity and social perception reinforce sameness? Drawing on cognitive theories of essentialism, sociological research on twin similarity, and Judith Butler’s concept of performativity, this paper argues that individuality for identical twins is not simply expressed, but actively performed in order to be recognized. Through analysis of theoretical scholarship alongside lived experiences—including personal narrative, twin studies, and ethnographic accounts—this paper demonstrates that twins face a unique tension between the expectation of visible difference and the reality of reinforced sameness. Recognition as an individual often depends on the ability to produce legible distinction, placing twins in a position where difference must be continuously demonstrated rather than assumed. The findings suggest that the performance of individuality is not optional, but necessary, and often comes with psychological consequences such as comparison, objectification, and anxiety. By highlighting this dynamic, the paper reveals the limitations of current theories of identity that assume recognition is readily available to all. Ultimately, the experience of identical twins exposes broader assumptions within Western individualism, showing that identity is not simply possessed, but depends on being recognized by others.
