Open communication is important for maintaining relationships when conflicts inevitably arise. Nevertheless, people may avoid constructive confrontation to the extent that they expect others to respond negatively. In experiments involving recalled (Experiment 1), imagined (Experiment 2), simulated (Experiment 3), and actual confrontations (Experiments 4a and 4b), we find that people's expectations are systematically miscalibrated such that they overestimate how negatively others respond to confrontation. These overly negative expectations stem, at least in part, from biased attention to potentially negative outcomes of a constructive confrontation (Experiment 5), and from failing to recognize the power of relationship-maintenance processes that are activated in direct conversations (Experiment 6). Underestimating how positively relationship partners will respond to an open, direct, and honest conversation about relationship concerns may create a misplaced barrier to confronting issues when they arise in relationships, thereby keeping people from confronting issues that would strengthen their relationships.
