In two longitudinal studies, university students, their roommates, and parents assessed the quality and forecast the longevity of the students’ dating relationships. The longitudinal nature of this research allowed assessment of the relative accuracy of predictions offered by students and observers. Students assessed their relationships more positively, focusing primarily on the strengths of their relationships, and made more optimistic predictions than did parents and roommates. Although students were more confident in their predictions, their explicit forecasts tended to be less accurate than those of the two observer groups. Students, however, possessed information that could have yielded more accurate forecasts: In comparison to parents’ and roommates’ evaluations of relationship quality, students’ assessments of relationship quality were more predictive of stability at 1 year. Implications of these findings for understanding biases and accuracy in prediction are discussed.
