Future self-perceptions seem to promote far-sighted decisions in intertemporal choices. Previous work suggested that future self-relatedness, the extent to which we feel similar and connected to our future self, is associated with moral concerns. We aimed to extend these findings to everyday moral judgments and behavior using experience sampling methods. In addition, we assessed how moral foundation concerns mediate the relationship between future self-relatedness and moral behavior. Participants (N = 151) reported their state-levels of future self-relatedness, individualizing, and binding moral foundations and answered whether they performed a moral action five times a day for seven days. Within- and between-participants future self-relatedness predicted daily fluctuations in individualizing and binding moral foundations concerns. On the behavioral level, only within-participants future self-relatedness predicted individualizing moral actions with individualizing moral foundations mediating this effect. Our findings suggest that within- and between-person changes in future self-relatedness might be used to predict everyday moral concerns and behavior.
