Prosocial lying, or lying that is intended to benefit others, is a ubiquitous phenomenon that can have profound consequences. Despite their prevalence and importance in social life, little research has investigated the causes and downstream effects of these lies. In this dissertation, I first define prosocial lies and explain how they fit into the theoretical framework of lying and deception. I also present empirical evidence for a causal driver of prosocial lies, and identify a key determinant of whether these lies are viewed favorably or unfavorably by their recipients.
