The Strategic Use of Fidelity in Romantic Relationships interrogates the monogamy myth by identifying the logical and pragmatic fissures in monogamy theory and practice. Beggan's expansive examination begins with a simple observation regarding divorce rates and proceeds to address previous research, popular defenses, and persistent assumptions regarding Western culture's continued valorization of monogamy particularly in its most common form, marriage. Beggan's provocative concept of “defensive monogamy” challenges existing conceptualizations and data regarding fidelity and is a significant contribution to relationship studies. Through “defensive monogamy,” he more accurately and more rationally describes the way in which relationships function and the ways they dysfunction. In the words of J. P. Morgan, people make decisions for two reasons: the “good reason” and “the real reason.” Beggan's excellent work investigates the real reasons we deploy monogamy and how those reasons frequently derail the fidelity and security couples seek.

The Strategic Use of Fidelity in Romantic Relationships trades moral panic for precision. It shows how control can masquerade as care, then offers language and tools to separate fear from values and to build agreements that fit real lives. Rigorous yet humane, it favors consent as practice, clarity about boundaries, and honest talk about risk and desire. As a scholar of ethics and communication, I admired its steadiness and respect for readers' values. As a reader, I felt seen. A smart, compassionate companion for anyone trying to keep love and honesty in the same room.

Defensive Monogamy explores the provocative idea that monogamy and fidelity may serve as strategic tools for self-protection rather than moral ideals. Drawing on psychology, behavioral economics, and evolutionary theory, James K. Beggan examines how individuals might use monogamy to influence partners and navigate the uncertainties of modern love. These hypotheses, rooted primarily in American perspectives, are intended to stimulate discussion and further inquiry into the complexities of intimate human behavior.
