So close, and yet so far: does collectivism foster transparency overestimation?

The present research demonstrated that horizontal collectivism (HC), the tendency to emphasize social bonds and interdependence, is associated with overestimating the extent to which one's preferences, feelings, and behavioral inclinations are transparent to close others. The link between HC and felt transparency was mediated by self-other merging but was not significantly mediated by perceived similarity, behavioral closeness, or metaperception positivity. Evidence of a causal connection was obtained in an experiment where individuals for whom interdependence was primed exhibited greater transparency overestimation than did those for whom it was not. Additional results indicated that higher HC is associated with greater confidence but not greater accuracy in judgments about a friend. The authors argue that other perspective-taking deficits involving overuse of the self in judgments of others should also be exacerbated by the self-other merging that is associated with HC.
