Preference for depth versus breadth in social relationships: Childfood socioeconomic background matters

Abstract

ABSTRACT Although the need for social connection is fundamental, people approach this need through different strategies. Drawing from life history theory, the current research explored whether individuals’ early-life experiences are associated with narrow/deep (depth), or broad/shallow (breadth) approach to social relationships. Three studies revealed that participants’ childhood socioeconomic status (SES) interacts with perception of economic instability to create diverging preferences in social relationship pattern. Specifically, when economic instability was salient (chronic belief, Study 1; experimentally primed, Studies 2 and 3), individuals from lower-SES childhood preferred a narrower and deeper social network, whereas those from higher-SES childhood preferred a broader and shallower network. Taken together, the present research offers a novel understanding of depth- versus breadth-focused approach to social relationships from the perspective of life history theory.
