Early Life Adversity Is Associated With Diminished Social Trust in Adults

Social trust is at the center of democratic societies, but it varies considerably between individuals and cultures. Socioeconomic status has been identified as an important predictor of such variability. Although this association has mostly been reported for measures of socioeconomic status taken in adulthood, recent studies have found unique effects of harsh conditions experienced during childhood on social trust assessed decades later. Here, we report a series of three studies that provide further support for the importance of early childhood conditions in social trust. The first study revealed that higher childhood socioeconomic status was associated with greater social trust in a diverse sample of French participants (N = 915), even after adjusting for current socioeconomic status. The second study confirmed this result using data from the European Values Survey (N = 64,780, 45 countries). In both samples, our analyses revealed that adding childhood socioeconomic status significantly improved the fit of the model thereby providing suggestive evidence of the central role of this variable for explaining variations in social trust. Finally, the last study replicated this association using a behavioral measure of social trust (N = 60 in original study, N = 75 in replication study).
