Since the 1990s sociology has rediscovered a theme already present in the discipline’s foundational theories: the salience of future perceptions for social action. This article provides an overview of “the sociology of imagined futures”, a diverse but still scattered research field explicitly engaged with expectations, aspirations and future orientations. A review of recent scholarship emphasizes how an imagined future perspective is related to a wide range of topics and allows for innovative vantage points on persisting sociological research concerns, such as inequality, social identities, agency, coordination, power or understanding innovation and change. By systematically highlighting these contributions, but also by pointing to promising lacunae and perspectives that merit further development, this article shows how a reorientation of sociological research “back to the future” seems a promising way forward.
