In this article, I discuss recent research dealing with bias and accuracy of judgments in romantic relationships. First, two components of overall accuracy—directional bias and tracking accuracy—are outlined. Second, a model is described dealing with the causes and consequences of bias and accuracy in partner and relationship judgments, and research is reviewed showing that partners generally exhibit both positive bias and good levels of tracking accuracy. The roles played by various moderating variables (e.g., relationship stage, individual differences) are also discussed. I conclude that bias in relationship judgments is largely functional and that interactions between partners both shape and are shaped by the directional bias and tracking accuracy attendant in relationship and partner judgments.
