RESUMEN
Throughout the course of scholarly history, some concepts have been notoriously hard to define. The 'common good' is one such concept. While the common good has a long and contested scholarly history, social psychology research on folk theories - lay beliefs that represent an individual's informal and subjective understanding of the world - may provide a key for unlocking this nebulous concept. In the current paper, we analysed lay definitions of the common good using the linguistic inquiry and word count's meaning extraction method. From a nationally representative Australian sample of open-ended text responses (n = 14,303), we uncovered a consistent conceptual structure, with nine themes corresponding to three core aspects: (i) outcomes and objects, (ii) principles and processes and (iii) stakeholders and beneficiaries. From this, we developed a working definition of the folk concept of the common good: 'achieving the best possible outcome for the largest number of people, which is underpinned by decision-making that is ethically and morally sound and varies by the context in which the decisions are made'. A working definition benefits the academic community and society more broadly, particularly when diverse stakeholders come together to act for the common good to address shared challenges.
