Comparisons Across Dimensions, People, and Time: On the Primacy of Social Comparison in Self-Evaluations

People often consider how their performance in one domain compares to their performance in other domains, the performance of other people, and their past performance (i.e., dimensional, social, and temporal comparison). The present research is the first to test whether social comparisons have a significantly larger effect on self-evaluations than dimensional and temporal comparisons. Study 1 participants received downward versus upward dimensional, social, and temporal comparison feedback (N = 393). Study 2 participants received downward versus upward comparison feedback for one type and lateral comparisons for the other two types (N = 281). Dimensional and social comparison significantly influenced self-evaluations and affective reactions in both studies. As anticipated, however, social comparison had a significantly larger effect on self-evaluations and affective reactions than either dimensional or temporal comparison. These data provide novel, causal evidence for the primacy of social comparison when people receive three feedback types.
