Interpersonal accuracy and interaction outcomes: Why and how reading others correctly has adaptive advantages in social interactions

Abstract

Interpersonal accuracy (IA), which is the ability to correctly assess others, is an important aspect of successful social interactions. But what exactly are the advantages of being interpersonally accurate in social interactions, and how does being able to correctly read and interpret nonverbal cues in others affect the outcomes of social interactions? In this chapter, we will explain what IA is and how it plays out in social interaction processes using a Brunswikian Lens Model approach. We will then provide an overview of the empirical findings showing the positive effect of IA for social interactions across many different contexts. Finally, we will introduce the Behavioral Adaptability Model to explain the process by which IA can positively impact social interaction outcomes.
