To belong or not to belong: some self-conceptual and behavioural consequences of identity uncertainty / Pertenecer o no pertenecer: algunas consecuencias de la incertidumbre identitaria en el autoconcepto y en el comportamiento

Abstract How does identity uncertainty affect the extent and way in which people identify with and define themselves in terms of prototypical group attributes? According to uncertainty-identity theory feelings of uncertainty about oneself and one’s identity are a powerful motive for identifying with and defining oneself in terms of a social group, particularly one that is a distinctive and clearly defined entity that furnishes a consensual group prototype. In this article I overview uncertainty-identity theory and some of its key findings, with a particular focus on how uncertainty-identity processes can produce extremism — zealous identification with and attachment to autocratically led, normatively homogeneous groups that are pronouncedly ethnocentric and intolerant of dissent. I also explore uncertainty-identity contexts in which groups may break apart and where people may be reticent about identifying with highly entitative groups — a discussion of marginalization, exclusion and schism.
