Globalisation generates intense debate and contradictory positions, being a particularly relevant object of social representations (SR). This article attempts to better understand the SR of globalisation by analysing how the normative social metasystem controls, verifies and selects the material produced by the operative system in contexts of social comparison. Using a multi-method approach, we conducted two studies, with semi-structured interviews (N=30) and a free association questionnaire (N=100), in the Porto Metropolitan Area, Portugal. Results highlight how social comparison contexts trigger arguments in favour of group interests and reveal the existing power relations between groups. The importance of identifying the relations that guide thinking about social objects and the applicability of SR theory for understanding complex, controversial, sociopolitical objects are discussed.
