This paper proposes a contribution to the investigation of the relation between multilingualism and creativity. Past evidence of a correlation between multilingualism and creativity is reviewed in a generalist perspective, that is, without focusing on a specific population such as migrants or highly proficient bilinguals. This review is also anchored in contemporary cognitive psychology and specialised research on creativity, allowing for a consideration of different levels and domains of creativity, as well as a distinction between creative potential and manifest creativity. On this basis, we test various hypotheses with a sample of 596 participants, using multiple regressions that incorporate several control variables. Key results show that L2 skills are systematically and positively related to virtually all indicators of creativity. Additional results reveal effects of other linguistic variables, along with effects of control variables related to cultural diversity (travelling and experience of living abroad), as well as interactions between linguistic and control variables. These results are contrasted with earlier findings and then discussed in terms of language policy implications and perspectives for future research.
