Meaning-making with romantic partners: Shared reality promotes meaning in life by reducing uncertainty.

We propose that, although deeply personal, meaning is facilitated by interpersonal processes. Namely, we theorize that experiencing a sense of shared reality with a close partner (i.e., perceiving an overlap in inner states about the world in general) reduces uncertainty about one's environment, which in turn promotes meaning in work and life. In the current research, we test this hypothesis across five mixed-method studies (e.g., longitudinal, experimental). We find cross-sectional evidence for this association in a couples' study (Study 1: = 103 romantic dyads) and in ecologically rich samples of people experiencing highly uncertain situations, specifically Black people consistently facing racism in the United States (Study 2: = 190 participants) and frontline health care workers directly treating COVID-19 patients during the height of the pandemic (Study 3: = 139 participants). Further, we provide causal evidence for this association in two experiments (Studies 4 and 5: ₄ = 364 participants, ₅ = 389 participants). Taken together, this work suggests that shared reality with close partners has real-world benefits, reducing uncertainty and promoting meaning. In addition, we show that experimentally heightening shared reality, by reducing uncertainty, can promote a greater sense of meaning in life.
