Whereas the behavioral and health sciences have been mainly concerned with the private good, there is an urgent need to understand and foster the collective good. Without a coherent framework for the common good, it will be extremely difficult to prevent and manage crises such as pandemics, illness, climate change, poverty, discrimination, injustice, and inequality, all of which affects marginalized populations disproportionally. While frameworks for personal well-being abound in psychology, psychiatry, counseling, and social work, conceptualizations of collective well-being are scarce. Our search for foundations of the common good resulted in the identification of three psychosocial goods: mattering, wellness, and fairness. There are several reasons for choosing them, including the fact that they concurrently advance personal, relational, and collective value. In addition, they represent basic human motivations, have considerable explanatory power, exist at multiple ecological levels, and have significant transformative potential. The complementary nature of the three goods is illustrated in an interactional model. Based on empirical evidence, we suggest that conditions of justice lead to experiences of mattering, which, in turn, enhance wellness. Challenges and opportunities afforded by the model at the intrapersonal, interpersonal, occupational, communal, national, and global levels are presented. The proposed psychosocial goods are used to formulate a culture for the common good in which we balance the right with the responsibility to feel valued and add value, to self and others, in order to promote not just wellness but also fairness.
