Expected mindreading is the belief that romantic partners should know one’s needs and feelings without overt communication. This dysfunctional belief is predicted to undermine relationship satisfaction, yet previous research provides mixed support. In two studies, I test my prediction that individuals higher in expected mindreading would be more reactive to misunderstandings by assessing relationship quality and attributions after participants imagined feeling understood or misunderstood by their romantic partner. In Study 1 (introductory psychology students), participants who felt misunderstood and were higher in expected mindreading were more likely to attribute misunderstandings to their partner’s lack of love than those who felt understood or were lower in expected mindreading. In Study 2 (community sample), satisfaction was lower for individuals who felt misunderstood and were higher in expected mindreading, compared to those who felt understood and were lower in expected mindreading. These findings have important implications for relationship counseling. / October 2016
