In 4 longitudinal studies, the authors explicated how storytelling about re
lationships biases subsequent impressions in the direction of the story tol
d. In Study 1, storytelling about a relationship conflict vignette biased i
mpressions of blame 2 weeks later, even with memory bias neutralized. Study
2 tracked 2 distinct and variable influences on blame,-storytelling heuris
tic and memory mediated mechanisms-over a 40-week period. Heuristic but not
memory mediated effects depended on story quality. In Study 3, the need fo
r structure moderated use of the storytelling heuristic. In Study 4, storyt
elling biased impressions of real-life relationship conflicts 8 weeks later
. In light of past research indicating that storytelling and idealization c
haracterize satisfied relationships, the present results suggest that the c
ognitive side effects of storytelling may help cause idealization and satis
faction in relationships.
