“Most studies of nonmonogamous relationships focus on their composition and consequences. But how do people decide to abandon monogamy in the first place? What difficulties do people face in doing so? How might they make better choices? In this rich book, James K. Beggan answers these questions by blending his grasp of the empirical literature on triadic relationships with a helpful decision-theoretic framework. The reader leaves with a nuanced sense of the different motivations, reasoning, and moral concerns surrounding these potentially transformative decisions. If you study human intimacy, read this book.”
